Circular Systems of Industry, Agriculture and Services — to follow the principle of optimized industrial processes, greatly supporting circular production.

Growth of the Recycling Industry — to recycle and reuse urban waste streams, focusing on remanufacturing and renewable energy.

Green Consumption — to guide citizens towards smart, healthy and safe consumption.

principles

  • Keep resources in use for as long as possible.
  • Recover and regenerate resources at the end of use.
  • Keep resources at their highest quality and value at all times.

No other natural resource offers the potential of hemp. Cannabis Hemp is capable of producing significant quantities of paper, textiles, building materials, food, medicine, paint, detergent, varnish, oil, ink, and fuel. Unlike other crops, hemp can grow in most climates and on most farmland throughout the world with moderate water and fertilizer requirements, no pesticides, and no herbicides. Cannabis Hemp (also known as Indian Hemp) has enormous potential to become a major natural resource that can benefit both the economy and the environment. Hemp is much easier to process than many materials whilst utilizing less energy and producing toxic by-products.

Industrial hemp is a different strain of Cannabis Sativa containing very little of the psychoactive substance found in marijuana. You simply cannot get high on industrial hemp.

Hemp is a genetically diverse species, with varieties adapted to a wide range of latitudes and climatic zones. It is a summer annual, short-day flowering plant, with 2-3 crops per year in some areas.  The fibre of the hemp plant comes from the stalk, which is comprised of bast (the outer bark fraction of the stem) and the hurd (which is the inner woody core).

Hemp as a fibre crop grows over the peak of summer, typically a 100-120-day crop.  It is a low-cost crop, with minimal infield operations post-planting.  A grower requires an appropriate licence or permit to grow industrial hemp.

Hemp is far more productive than typical agroforestry projects, producing annual, versatile biomass alongside more rapid CO2 uptake. It can produce a vast range of sustainable raw materials with an overall low environmental impact, as well as improving soil structure, using low fertiliser and no other chemical inputs (i.e. reduced agrochemical residues).

Hemp can be grown on existing agricultural land (unlike most forestry projects) and can be included as part of a farm’s crop rotation with positive effects on overall yields of follow on crops. This, along with super versatility in diverse soil conditions and climates, makes hemp cultivation a viable and genuine potential large-scale contributor to GHG mitigation.

Opportunity for a Sustainable Solution

The use of hemp as a building material is more environmentally friendly and sustainable than conventional building materials.

Green building is the science of creating a structure that is energy-efficient, resource-efficient and environmentally responsible. It is the art of building design that minimizes the negative impact on the environment by incorporating efficient application of resources through effective utilization of wind, water and sunlight.

On a practical level, this encompasses the use of design, materials and technology to reduce energy and resource consumption and create improved and healthier conditions for humans and the environment.

Hemp is naturally resistant to most pests, so it doesn’t need pesticides or herbicides. In rotation, it leaves a weed-free field for the next crop. Huge reductions in chemical use can be achieved by returning to rotation agriculture. Hemp grown in rotation with wheat in England resulted in a 20% increase in wheat yield, without any commensurate increase in chemical or energy inputs. In Ontario, hemp grown in rotation with soybeans reduced cyst nematode infestation by 50-75%, reducing the need for chemical pesticides.

A limiting factor in sustainable agriculture is the lack of profitable rotation crops. Hemp could be quite profitable. Studies in Wisconsin and Kentucky suggest that per-acre profits from hemp could exceed most other crops. Hemp’s extensive root system and the falling leaves in the field (the stalks are what are sought) leave better soil tilth. Hemp needs fertilization, as it consumes a lot of nitrogen. Because it is fast-growing and has an extensive root system, it might be useful in removing excess nitrogen fertilizer from fields, thereby reducing agricultural runoff problems. On fields where nitrogen is the limiting factor to crop growth, hemp requires about 50% of the nitrogen fertilizer as corn.

50% of all pesticides used in America are associated with cotton. Hemp can substitute for many uses of cotton.

Farmers are losing money on corn, wheat and soybeans. In North Dakota, farmers have been making more by selling the wheat straw to a particleboard plant than from selling the grain. Hemp can make a difference in the agronomic equation. Due to the bulkiness of the fibre, local processing facilities will have to be built near the farms. This can provide new jobs for rural America.

Local Reports in durban, kwazulu-natal

KZN farmers could benefit with $7.1bn per year from licenced cannabis cultivation

By Helmo Preuss Time of article published Mar 31, 2019

DURBAN –  A recent report by Prohibition Partners forecasts that Africa could benefit by US$7.1 billion per year by 2023 if cannabis cultivation is legalised. 

As KwaZulu-Natal (KZN) has an ideal climate for the cultivation of cannabis, many KZN farmers would benefit from licenced cannabis cultivation.

The World Health Organisation estimates that South Africa is the third-largest producer in the world of cannabis, which employs some 1.2 million people made up of 900,000 cannabis farmers and 350,000 traditional healers who grow their cannabis for medical reasons.

The African Cannabis Report, the first detailed report on the legal cannabis industry in Africa, found that the continent could reap significant rewards through the legalisation of cannabis as it would improve a country’s balance of payments, support the local currency so reducing imported inflation, and create many thousands of jobs.   

Daragh Anglim, Managing Director at Prohibition Partners, said legal cannabis cultivation could be a game-changer for the continent. 

In this Wednesday, Oct. 5, 2016 photo, a government forest worker destroys fully grown marijuana plants in Malana village in the northern Indian state of Himachal Pradesh. Nestled deep in the higher reaches of the Indian Himalayas, Malana has become one of the world’s top stoner destinations, and a symbolical battleground for India’s fight against ‘charas,’ the black and sticky hashish that has made the village famous. While the rising demand and price of “charas” has benefited the villagers, it has also led to a slight increase in prosecutions and prompted the government to send machete-wielding police and forest personnel on long treks to destroy a small percentage of the marijuana fields. (AP Photo/Rishabh R. Jain).

A regulated legal cannabis market could be transformative to patients, farmers and economies across Africa. From a financial standpoint, Africa could reap significant rewards through the legalisation of cannabis, with international demand offering a strong commercial opportunity for cannabis cultivation,” he said. Despite moves to legalise the cultivation of cannabis for medical products in several key markets such as South Africa, Lesotho and Zimbabwe, cannabis remains illegal across most of the continent as the great majority of African government have yet to follow the trend of legalisation that is sweeping across Europe, North America and Latin America.

 Assuming there are full legalisation and regulation of the cannabis industry, South Africa and Nigeria potentially represent the region’s two largest value medicinal cannabis markets going forward, worth US$667m or around R9.7 billion or around a tenth of the foreign exchange generated by gold mining to South Africa and US$75m to Nigeria by 2023. 

Africa has a long history of cannabis cultivation and many farmers have turned to illegal cannabis cultivation as the only means of subsistence since the decline in demand for other crops such as tobacco. According to figures from the United Nations (UN), South Africa produces around 2,500 tonnes of cannabis per year and a significant portion of that is grown in KZN. 

 Following the decision to legalise the private use of cannabis in South Africa in September 2018, a fledgeling industry capitalising on the various uses for the plant has sprung up with the first cannabis exhibition and trade fair held in December 2018.

 In 1999, the Department of Health issued the legal permit to the House of Hemp to research the health benefits of pharmaceutical-grade cannabidiol (CBD) and other cannabinoids. Based out of Dube Tradeport at King Shaka International Airport‚ the company was established in 1999 as part of the National Hemp Foundation project which was formed to conduct legal research into hemp fibre and seeds‚ fibre production‚ and hemp CBD.

In May 2018, South Africa’s first medical cannabis dispensary opened in Durban. One of the centre’s founders creators is Krithi Thaver, the founder of Canna Culture and chair of the KwaZulu-Natal branch of the Cannabis Development Council of South Africa. 

The Holistic Relief Wellness and Pain Management Centre is said to combine traditional medical practices in chiropractic, physiotherapy, diseases and illnesses (acute and chronic) to treat the whole body.

Patients will see a doctor, chiropractor or traditional healer who will consult and prescribe them different strengths oils infused with cannabis and ayurvedic ingredients.

 Anecdotal reports are that the cannabis seed banks are low on stock because everyone has started to cultivate cannabis on their private properties, with many old age homes, where many people suffer chronically.

 Law firms are looking to the inevitability in a change of labour laws, but many employers have reiterated by letter to their employees that there is still a zero-tolerance for illegal drugs in their workplace. Many estate agents and landlords have posted a notice that as far as they are concerned “weed” is still illegal and its use will not be tolerated on their premises. To satisfy the need for knowledge on cultivation and how to process the feminized cannabis into medical-grade CBD using coconut oil, many Internet-based growing guides are springing up, while indoor grow shops are flourishing and many seminars are held with visiting international keynote experts.

Medicinal Hemp & Cannabis

According to a report from the World Health Organization, “In humans, CBD exhibits no effects indicative of any abuse or dependence potential…. To date, there is no evidence of public health-related problems associated with the use of pure CBD.” CBD has been touted for a wide variety of health issues, but the strongest scientific evidence is for its effectiveness in treating some of the cruellest childhood epilepsy syndromes, such as Dravet syndrome and Lennox-Gastaut syndrome (LGS), which typically don’t respond to antiseizure medications.

In numerous studies, CBD was able to reduce the number of seizures, and in some cases, it was able to stop them altogether. Videos of the effects of CBD on these children and their seizures are readily available on the Internet for viewing, and they are quite striking. Recently the FDA approved the first-ever cannabis-derived medicine for these conditions, Epidiolex, which contains CBD.

CBD is commonly used to address anxiety, and for patients who suffer through the misery of insomnia, studies suggest that CBD may help with both falling asleep and staying asleep.

CBD may offer an option for treating different types of chronic pain. A study from the European Journal of Pain showed, using an animal model, CBD applied on the skin could help lower pain and inflammation due to arthritis. Another study demonstrated the mechanism by which CBD inhibits inflammatory and neuropathic pain, two of the most difficult types of chronic pain to treat. More study in humans is needed in this area to substantiate the claims of CBD proponents about pain control. This is the least developed realm of treatment, however, research to date shows that CBD and medical marijuana shows promise in treating; dementia, cannabis dependence, tobacco and opioid dependence, psychoses and schizophrenia, general social anxiety, posttraumatic stress disorder, anorexia nervosa, attention-deficit hyperactivity disorder, Parkinson’s disease and Tourette’s disorder.

CBD can in fact “counteract the undesirable effects of the psychoactive cannabinoid Δ9-tetrahydrocannabinol (Δ9-THC) that hinder clinical development of cannabis-based therapies” as “CBD blunts Δ9-THC-induced cognitive impairment in an adenosine A2A receptor (A2AR)-dependent manner.”

Consumer interest has been particularly focussed on the use of CBD for anxiety. Multiple studies have found that CBD use significantly reduces anxiety.

CBD oil has therapeutic and health benefits for both humans and animals, alleviating aches and pains from conditions like arthritis. Fortunately, hemp plants grow and regenerate quickly enough to keep up with growing industry demand.

The use of hemp as a building material is more environmentally friendly and sustainable than conventional building materials.

Green building is the science of creating a structure that is energy-efficient, resource-efficient and environmentally responsible. It is the art of building design that minimizes the negative impact on the environment by incorporating efficient application of resources through effective utilization of wind, water and sunlight.

 On a practical level, this encompasses the use of design, materials and technology to reduce energy and resource consumption and create improved and healthier conditions for humans and the environment.

 

  • It takes just 2.5 acres of hemp to produce enough hemp shiv to build a 1, 250sq ft house.
  • If 900 traditional homes were built using industrial hemp, over 45 000 tons of CO2 would be saved during the building process.
  • 40 percent of the world’s global energy is consumed by the construction sector.
  • 25 percent of the world’s water is consumed by the construction sector (un environment program 2016).
  • December 5th is UN world soil day; the building industry has thus been called to account for its role in the massive use of mineral raw materials and environmental pollution. The construction sector is one of the major sources of soil, air and water pollution.
  • 40 percent of the global raw materials is used by the building industry.
  • 50 percent of CO2 emissions into the atmosphere come from the construction sector.
  • The production of cement contributes to 10% of all industrial carbon emissions as opposed to hemp which absorbs 10-110kgs per metre cubed.
  • For every 100kg of cement produced- 900kg of CO2 is emitted into that atmosphere.
  • The construction industry in south Africa and the use of buildings accounts for over half (50%) of the carbon dioxide produced.
  • Conventional building produces up to 200kg of CO2 emissions in the production of each square metre of walling for houses alone, equating to 40 tons for the walls of a typical house.

 

 

hempcrete

What is Hempcrete?

Hempcrete is a concrete substitute made with hemp hurds and a binder (Lime).

Woody core is typically used in the construction industry and is transformed into particles of 2-25mm in length called hemp hurds or shiv. Hemp hurds constitutes between 60 to 80% of the hemp stalks mass, making it ideal for the use of construction.

The intentions of hempcrete and its applications are to improve materials on a thermal, hygrothermal and acoustic scale, creating a carbon-storing envelope.

Similar to conventional methods and tools used, so no need for further education of labour for the applications. Hempcrete is a sustainable and eco-friendly alternative that is non-toxic and safe to work with.

benefits of hempcrete

  • Allows for natural ventilation.
  • Hempcrete stores heat or internal heating in the thermal mass in its walls, to be released slowly as the building cools down.
  • Maintains constant temperature inside building so little heating or cooling is required.
  • Keeps the building cool in summer and warm in winter with a dramatic reduction in fuel bills.
  • Building with hempcrete and hemp blocks is considerably lighter due to its low density meaning cheaper transport of materials that are lighter and stronger. When using a lighter and stronger material transport costs are reduced.
  • Improved health of the building’s occupants.
  • Prefabricated hempcrete walls are faster and cheaper.
  • Buildings will need to pass tensile strength, energy efficiency, compression and increase of performance due to high thermal mass.
  • Hempcrete can be used for roofing.
  • No need to heat up for industrial use like concrete.
  • Will cut energy costs significantly.
  • Hemp houses can last 300-800 years as opposed to houses created from concrete that last 80 years.
  • Hemp homes are biodegradable, leaving no waste in their wake.
  • Hempcrete is carbon negative. Due to its composition, it holds carbon dioxide within its structure, thus significantly reducing carbon emissions in and around the house.

hempcrete in action

Tony Budden and his partner Duncan Parker aimed to give the Hemp House the lightest carbon footprint possible but had to import most of the materials since South Africa lacks a domestic supply of hemp products. The internal modular walls are comprised of hemp insulation and sealed with magnesium oxide boards, while the external walls are made from a lime-based hempcrete that is considerably less energy-intensive to produce and less dense than traditional cement. But what makes the building South Africa’s most sustainable?

It is passively cooled, heated, and ventilated, incredibly well insulated, and partly powered by solar energy. The floors are made from sustainably-sourced cork, 85% of the furniture and cabinetry is made from hemp board, and all of the grey and black water will be treated and recycled. Also included are LED lamps to reduce energy use, eco-paints to prevent harmful off-gassing, and reclaimed stone.

Not only is the Hemp House an impressive achievement in sustainable building, but Budden’s determination to overcome misguided regulatory roadblocks to illustrate the huge environmental and social advantages of growing hemp locally puts this groundbreaking home on par with Nelson Mandela and Desmond Tutu peace efforts. Already government officials are reconsidering their formerly-held bias against what is an excellent antidote to water and chemical-happy fibres such as cotton.

Specific green building measures’ include careful building design to reduce heat loads, maximize natural light and promote the circulation of fresh air. Many building contractors and surveyors are unaware of the use of hemp in building materials and availability in South Africa or Africa. Buildings and applications using Hemp will need to become GREEN STAR SA CERTIFIED 

Hempcrete can be mixed with various binders such as sand, gypsum, metakaolin, pozzolan or even cement. Hempcrete can be used for manually compacted, casted walls, sprayed insulation coatings, external and internal plasters, premade blocks and panels for non-load bearing or load-bearing applications, floor slabs, slabs and roof insulation, including structural application like vaults and cupolas. Hempcrete mixtures can use industrial or agricultural lime and for environmental and economic reasons, non-calcined binders e.g. Clay or soil-based are preferable in load-bearing applications.
Hydraulic lime, as well as mixes of aerial lime (carbonates-hardens slowly-climate sensitive) pozzolanic aggregates, are favourable options to accelerate the hardening process of hemp concrete and allow setting with important coatings or wall thickness without compromising the water vapour diffusion compared to an aerial lime binder. Humid climates require precise constructive measurements when using gypsum, un-stabilized clay and organic binders to protect them from water. Possess a porous Intra and inter particular structure of up to more than 70%.

Fiberboard/Particle Board

Particleboard is an engineered wood that is less expensive, and generally more uniform than wood and plywood. Wood scraps, fragments and even sawdust are commonly used, and agricultural fibres such as hemp can be used in a board making process, whether wholly or in blends. The short fibre and low density of hemp’s core fibre make up 70-75% of the total hemp biomass, making it suitable for lightweight particleboard. Hemp’s longer bast fibres can also be cut into strands for structural composite board manufacture.

While hemp and other crops have considerably different harvesting and storing logistics than wood, the use of agricultural fibres to supplement wood supply and in some cases displace wood materials has a lot of potentials.
The wood used in Particleboard which is used in construction and other applications can be substituted with Hemp hurds creating a lighter, stronger and eco-friendly building alternative.

Bio-diesel can be made from the oils in the seeds and stalks for machinery to run eco-friendly.

Reduced operational energy.
Flammable classification B1 or B2.

Plaster

Primarily used for insulation qualities.

Only applied to areas where the material is only required to stay in place, such as loft spaces and between floors.

Only about 10% of the volume is lime to coat the hemp particles and bond them to each other.

Has greater flexural strength than traditional lime plasters making it extremely durable e.g. it is far more resilient for use on corners, reveal and other vulnerable areas of the building.

It is easier to use than conventional lime plasters due to minimal shrinkage even on high suction backgrounds offering reduced labour costs.

A solid lightweight fibre reinforced material that combines masonry and organic qualities providing good breathable, flexibility and water-repelling qualities.

insulation

While hempcrete is in a sense a form of insulation, it requires its own building system. Hemp insulation is made from the hemp plant’s long bast fibres and is available as mats and rolls. The products can be used in new or old buildings as a substitute for fibreglass based insulation.

According to manufacturers, hemp fibre insulation has optimal moisture regulation and has a high thermal resistance. Lacking protein, it is highly resistant to mould growth, dust, and other pollutants. Soda added to the insulation adds to fire resistance values. There’s even a variety of manufacturing blends involving long fibre hemp insulation, including recycled cotton and polyester.

One cubic metre of hempcrete insulation absorbs 60-110kg of C02 from the atmosphere.

Non-toxic and better to work with as you don’t need gloves, goggles or masks.

50-80% energy savings due to its high insulation value.

Prefabricated hempcrete walls allow for fast and cheap installation

wall hempcrete

20% of lime is used in the mixture. Used to withstand forces of impact, wind loading and the additional structural rigidity. More lime is used to solidly bond the hemp particles together but to retain insulation properties. Shuttering is used in the application. Soil can be added for structural support in load-bearing areas.

spraying hempcrete

One method of application is spraying against formwork. To mix the hempcrete, hemp hurds or shiv are combined with lime and water. placed in a hopper which then is lifted into the adaptive mixer which finishes the process.

Hempcrete Vs Concrete

Hempcrete
Concrete
Bio-composite that is made from the inner wood core of the hemp plant and mixed with the lime and other natural materials. It is also known as hemp-concrete.
The final product resulting from mixing cement, aggregates (including sand), water, and mixtures. It is initially malleable in its “wet” state and solidifies over time, gaining strength and durability.
Versatile building material can be used for wall insulation, flooring, walls and roofing. Used above ground, it’s fire-proof, water-proof, rot-proof and termite resistant.
It is an important construction material used extensively in buildings, bridges, roads and dams. Its uses range from structural applications to paviours, kerbs, pipes and drains. Concrete is a composite material, consisting mainly of Portland cement, water and aggregate (gravel, sand or rock).
Hempcrete houses need little cooling or heating to stay comfortable, and thus save lots of energy.
The main energy benefit of using concrete in buildings is its high thermal mass that leads to thermal stability. According to the European Concrete Platform, this saves energy and produces a better indoor climate/environment for building occupants and users.
3 times more resistant to cracking from earthquakes than regular concrete.
Less resistant to cracking from earthquakes than regular Hempcrete.
Lightweight building material weighing 1/7th of concrete.
Heavier building material compared to Hempcrete.
Fully recycled material which can be reused for making fertilizers.
Not recycled material

benefits

  • Humidity Control– Hempcrete is highly hygroscopic meaning that it absorbs humidity from the air. This is a good thing! Hempcrete can hold and shed moisture depending on the weather and climate so when there is a lot of moisture in the air the walls will absorb and hold moisture, when humidity is low the walls begin to shed moisture. This creates a very consistent and comfortable humidity level for the interior throughout various weather cycles while also prevent condensation and the chance for mould.

     

  • Monolithic Design– Because hempcrete is cast in a wall it creates a monolithic or continuous, structure which means there is little to no thermal bridging (“cold spots”). You get consistent insulation and seal from pests and the outdoor elements.

     

  • High insulation value and thermal mass– With hempcrete, there is no need for any other layers within your walls, including insulation, because that is what hempcrete does best. Hempcrete can absorb heat and dissipate it over a longer period, so during the day the walls will absorb heat and by night time it will have just begun to start releasing that heat to the interior to keep you warm all night. This is also great because it eliminates the need for robust HVAC systems in your home which will save you money.

     

  • Fire/Bug/Mold Resistant– Lime has natural fire-resistant qualities and when cast and cured in the hempcrete mix the walls become highly fire resistant with the ability to resist flame for several hours. Again, thanks to the lime, hempcrete homes see little to no bugs, including mites! The mould-resistant aspect is attributed to the hemp hurd and as mentioned early, hempcrete is hygroscopic and it can regulate its humidity levels and shed excess moisture when over-saturated.

long term sustainability

Hempcrete is carbon negative meaning while hemp grows it absorbs an abundant amount of carbon from the air, approximately 4 times more than the same area of trees. After it is harvested, broken down for hempcrete, then mixed and then cast into a house, it continues to absorb CO2 for up to 100 years!

Natural is better for us and our planet. Growing and innovating with sustainability and renewability as our foundation will lead to long term success, not just for us but for generations to come.

The cultivation of hemp will aid the environment to reduce the negative impact of global warming. A whole range of sustainable building products is currently being made from all parts of the hemp plant for use in restoration and new building projects. Hemp construction uses renewable crop-based materials which absorb carbon dioxide (CO2) as they grow, providing an opportunity to capture and store CO2 in the fabric of buildings. Hemp fibre is made into ‘user-friendly’ recyclable materials which do not contain harmful ingredients. Compressed hemp shiv is used to make a fibreboard but by far the most exciting development is Hempcrete, a material that can be used for construction.

Insulation Applications

Low-density hempcrete bio-composite used to insulate roofs or subfloors.

Loose wool can be made from the bast fibre for insulation which is non-toxic.

Thermo-welded insulating panels (85% hemp fibre or 80% hemp fibre and hurds) are lightweight and non-toxic.

Fibre is used(bast) and made into a quilt, very similar to glass fibre or mineral wool insulation

Densities for Application

Sprayed coatings or void filler-200-250 kg/m3

Wall mixture non load-bearing-400-500kg/m3

Plasters, external renders-600-1000kg/m3

Load bearing external walls-600-1000kg/m3

Lime

One ton of manufactured cement (1400–1450 °C) releases 850kg of carbon dioxide into the atmosphere! This is a consequence of the chemical reaction and cannot be reduced by energy saving.

The use of lime instead of cement will save approximately 80% of the CO2 release compared to ordinary cement. One single residence will save between 5,000 and 10,000 lbs of CO2 emissions.

Health Benefits of Living in a Hemp Home

bio-fuel

Fuel for the Future

Hemp has been successfully used for many years to create bioethanol and biodiesel, is environmentally friendlier to produce than sugar beet, palm oil, corn or any of the crops used in conventional Bio-Fuel production band can grow in practically any temperate to hot climate leaving the ground in better condition than when it was planted. The point where the cost of producing energy from fossil fuels exceeds the cost of biomass fuels has been reached. With a few exceptions, energy from fossil fuels will cost more money than the same amount of energy supplied through biomass conversion.

Hemp biofuel comes from hemp seed oil — the same seed oil you can drizzle on salads, add to a smoothie or feed to livestock — and the rest of the plant can be made into either ethanol or methanol. The global push towards utilizing a greater amount of sustainable resources to reduce our dependence on polluting energy sources such as fossil fuels has led to an increasing amount of research devoted to alternative energy sources.

Commonly known alternative energy sources include solar, wind, hydroelectric, geothermal and biomass energy. Since you can produce 10 tons of hemp per acre in four months, it is the planet’s No. 1 biomass source. Just 6 percent of the continental United States could be used to provide the biomass needed to fill all of the country’s energy needs. Because it grows quickly in mass quantity, this renewable resource is more ecologically responsible and better for the earth than the deforestation that tears down forests for wood products. Bioenergy is currently the fastest-growing source of renewable energy. Cultivating energy crops on arable land can decrease dependency on depleting fossil resources and it can mitigate climate change.

Enthusiasts have been promoting the use of industrial hemp for producing bioenergy for a long time now. With its potentially high biomass yield and its suitability to fit into existing crop rotations, hemp could not only complement but exceed other available energy crops. Biogas production from hemp could compete with production from maize, especially in cold climate regions such as Northern Europe and Canada. Ethanol production is possible from the whole hemp plant, and biodiesel can be produced from the oil pressed from hemp seeds. Biodiesel production from hemp seed oil has been shown to overall have a much lower environmental impact than fossil diesel. Sustainable bioenergy production is not easy, and a diversity of crops will be needed.

Industrial hemp is not the ultimate energy crop. Still, if cultivated on good soil with decent fertilisation, hemp can certainly be an environmentally sound crop for bioenergy production and other industrial uses as well. Plants possess several biomass components that have been transformed into currently used fuel sources. Additionally, plants also possess a wide variety of phytochemicals that are shown to successfully mimic liquid fuels and therefore potentially

CBD hemp fuel can be used as is, as biogas or liquid biofuels. The process of extracting fuel from biomass is through chemical decomposition or biological digestion. From the processing of the waste from the cannabis plant, we get a carbon nanomaterial which is the primary material in high power batteries and super-capacitors.

“Dried biomass has a heating value of 5000–8000 Btu/lb. with virtually no ash or sulphur produced during combustion. About 6% [to now 10%] of contiguous United States land area put into cultivation for biomass could supply all current demands for oil and gas. And this production would not add any net carbon dioxide to the atmosphere.”

A biofuel-based infrastructure would create a completely decentralized power grid and no more ultra-mega power companies. Each county and state could provide its own energy using easily renewable plants. Let that seed sink into the garden of your mind…

In Colorado, a company called Vega Biofuels offers bio-coal — which is renewable, comparable in price to conventional coal and produced using Terre faction technology — and biochar which can sequester carbon in the soil for hundreds to thousands of years without the negative impacts.

Using hemp as biomass fuel would also reduce global warming because the hemp energy crop would pull carbon from the air and release an equal amount when burned, instead of just releasing carbon as petroleum gasoline does now. Using hemp biomass to make charcoal, could eliminate the need to burn petroleum coal. Hemp biomass burns with virtually no sulphur emissions or ash, which minimize acid rain caused by the burning of coal.

A by-product

Almost any type of plant or organic material can be converted to fuel, and the advantages that these alternative fuel sources have over fossil fuels are huge. Below are some of the advantages:

Plants contain little to no sulphur components or other contaminants that are commonly found in gasoline. These contaminants are associated with causing air pollution and the subsequent promotion of acid rain.

Photosynthesis is the process by which plants convert water and carbon dioxide (CO2) into carbohydrates and oxygen. The production of biomass recycles CO2, a major contributor to global warming, back into the fuel source, which is also beneficial for the environment.

No mining, strip-mining or drilling is required to harvest plants, as compared to those processes that are used for the extraction of oil.

Converting Hemp to Fuel

As a crop, hemp exhibits good resistance to drought and pests, a well-developed root system that is resistant to soil erosion, as well as a much lower water requirement as compared to other crops like cotton. Hemp is, therefore, a highly versatile fibre crop that is particularly unique for its possession of both a high percentage of useful oil and biomass components.

Historically, hemp biomass has been used for energy purposes, however, its use for this purpose was traditionally limited to the use of oil that was pressed from hemp seed to provide lighting for some applications.

In 2011, Dr Thomas Prade of the Swedish University of Agricultural Sciences investigated the energy yield of hemp for its potential application as both a solid biofuel and biogas and comparing this data to other commonly used energy crops in northern Europe. In his work, Prade determined that industrial hemp exhibits a high energy yield per hectare, as well as a good specific methane yield that could be increased through the pre-treatment of biogas2.

Additionally, a group of researchers from the University of Connecticut have also confirmed that physical and chemical properties of biodiesel derived from unrefined hemp soil meets the standards set by the American Society for Testing and Materials for biodiesel fuel2. According to some, industrial hemp biofuel performs second only to algae.

hemp paper

What is hemp paper?

Hemp paper is made from hemp plants’ bast fibre. The paper created from the short bast fibre (pulp) is easy to make, soft, thick and great for everyday use.

The chemical composition of hemp bast is similar to that of wood, making hemp a good choice as a raw material for manufacturing paper.

The quality of the paper is higher than that of paper, as hemp bast is much better for paper than wood bast.

Hemp was widely used across the world in the 1800s but declined in the early 1900s as hemp production and trading started to be prohibited.

Benefits of hemp paper

Hemp paper is a valuable alternative to conventional paper made from trees and could provide a more renewable source for much of the worlds paper needs.

Due to hemp growing faster than trees, it is a better sustainable alternative.

  • 1 acre of hemp can produce as much paper as 4-10 acres of trees over a 20-year cycle.
  • Hemp stalks grow in 4 months, whereas trees take 20-80 years.
  • Hemp has a higher concentration of cellulose than wood, the principal ingredient in paper.
  • Trees are made up of only 30% cellulose, requiring the use of toxic chemicals to remove the other 70%. Hemp, on the other hand, can have up to 85% cellulose content.
  • Hemp has lower lignin content than wood. Hemp contains 5-24% lignin whereas wood has 20-35%. This is advantageous as lignin must be removed from the pulp before it can be processed as paper.
  • Hemp paper is more durable than trees. Hemp paper does not yellow, crack, or deteriorate like tree paper.
  • Wider use of hemp paper can help sustainability efforts to reduce deforestation.
  • Hemp paper uses Hydrogen Peroxide which is safe and natural, instead of chlorine and bleach.
  • In America, the pulp and paper industry is the third-largest contributor to pollution, pumping over 220 Million pounds of toxic pollutants into the environment every year.

 

hemp textile

What is hemp textile?

Hemp textiles are made from hemp fibres. The hemp textiles are extremely versatile and have been used to manufacture clothing, ropes and canvas.

Textiles created using hemp are extraordinarily tensile and durable that last longer than conventional cotton textiles.

As a fabric, hemp provides all the warmth and softness of a natural textile coupled with a superior durability seldom found in other materials.

Benefits of hemp textile

  • Arguably superior to other natural fibres, both in terms of cultivation and application.
  • Fewer imports to grow and less water needed than cotton.
  • Industrial Hemp is pest and disease resistant: partly due to the fact that t grows so fast.
  • Low lignin levels enable environmentally friendly bleaching without the use of chlorine and bleach.
  • Far more fibre can be produced from hemp than flax or cotton, using the same amount of land.
  • Cotton is small woven strands-hemp bast fibres are 12-18ft.
  • It’s one of the strongest natural fibres.
  • Less stretch so clothing retains its shape.
  • Its softness increases with use.
  • When dyed, it retains colour better than cotton.
  • A great insulator.
  • Anti-bacterial properties.
  • Excellent breathability and high abrasion resistance.
  • Resistant to mould and mildew.
  • Superior UV blocking abilities.
  • Less environmental impact across all industries.
  • Hemp provides 250% more fibre than cotton.
  • Many variations of hemp-silk, Denim, Suade.
  • Non-Toxic.

“Total greenhouse gas emissions related to textiles production are equal to 1.2 billion tons annually — more than those of all international flights and maritime shipping trips combined, according to the Ellen MacArthur Foundation.”

hemp bio composites

Hemp bio-composites are stronger, lightweight and more durable. Thomas Edison stumbled upon the ability to make a new super-strength material way back in 1879 during a light-bulb filament experiment. Edison heated splinters of bamboo to incredible temperatures, and the result was strands of carbon capable of withstanding tremendous heat; the material was also able to conduct electricity.

Fast forward to 1958, and Roger Bacon expanded on the experiment by creating ‘whiskers’ with triple the stiffness of steel, and 10 times the tensile strength. It was eventually manufactured into a substance we know as carbon fibre. However, hemp has an even greater tensile strength! New material was ‘discovered’ by the journal Science in 2004. Known as graphene, this material is a form of carbon which exists as a sheet with the thickness of an atom. It is said to be 100 times stronger than steel, and it conducts electricity better than copper. All it takes is 1% of graphene mixed into plastics to provide conductivity.

After several years of intensive research led by Mercedes Benz, the use of natural fibres in composites were found to meet or exceed the high-performance demands required for strength and durability. Natural fibre composites are made of a mixture of 50% hemp and 50% polypropylene (PP) which are formed into fleece mats and are later formed into various components.

The use of natural fibres in automotive composites versus fibreglass results in both ecological and technological benefits. When compared to traditional fibreglass, natural fibre composites do not splinter on impact, use less energy to produce, have lower material cost, and are recyclable.

driving forces for the increasing use of PFRCs are government mandates for better fuel economy and end-of-life vehicles directives.

What Are Hemp Bio-composites?

To answer that question, you first need to understand a couple of other terms:
 
Composite Material

A composite material is made from at least two or more constituent materials with different chemical or physical properties. When combined, this ‘composite’ produces a material with traits different from the separate components. Composite wood, such as plywood, is a prime example.

Biocomposite Material

A biocomposite material is formed by a matrix (resin) along with reinforced natural fibres. The resin is formed by polymers that come from non-renewable and renewable sources. The resin protects the fibres from mechanical damage and degradation from exposure to the environment. The bio-fibres used include recycled wood, cotton, flax, or hemp.

Using this information, we can now say that a hemp biocomposite means using hemp to reinforce composites. Blending materials include polyethene, polyester, and polypropylene. It is possible to use a 100% biocomposite because you can add canola, corn, or soy as plant-based resins.

Hemp biocomposites are used in various consumer products, including furniture and automotive interior substrates. Manufacturers use hemp fibre to produce mineral-based composites akin to using glass fibre to reinforce plaster or cement.

The idea of making cars from hemp is more than a fad as major manufacturers prepare for the hemp revolution. Researchers in England and Australia have been developing materials from hemp for almost 20 years. When car-makers finally embrace hemp, they will find that even creating an outer shell from hemp fibres will make a difference. Imagine a scenario where a car’s body doesn’t rust?

In the United States alone, over 11 million vehicles reach the end of their useful lives each year. Admittedly, different facilities process all but 4% of these vehicles, while 25% of the vehicles by weight become waste. This waste mainly includes fibres, foams, rubber, glass, and plastics.

Theoretically, a car made from hemp could degrade underground. At present, it is mainly European companies looking into making cars from hemp. However, GM’s movement in the United States, plus the fact that industrial hemp cultivation is now legal, means that other car firms will have to update their manufacturing processes or risk falling behind.

Hemp Based Graphene

Graphene is a ‘super-material,’ yet hemp can mimic many of its best properties. For example, waste fibres from hemp crops could be turned into high-performance energy devices. At an American Chemical Society meeting in 2014, a team of researchers produced the results of a remarkable experiment. They subjected cannabis bark to high temperatures to turn the material into carbon nanosheets and were able to create supercapacitors at a level equal to, or greater than, graphene. For the record, supercapacitors are energy storage devices which transform the way your electronics are powered. Old-fashioned batteries store reserves of energy and drip-feed it slowly.

In contrast, supercapacitors discharge their full load, which makes them ideal for machines such as electric cars where quick bursts of power are essential. Graphene makes excellent supercapacitors but is incredibly expensive to produce. While hemp is unable to do everything graphene can, it works just as well for energy storage and costs a few hundred dollars per ton.

“A supercapacitor is a common tool for storing electrical energy. Graphene, a one-atom-thick version of common graphite and carbon nanomaterial is a supercapacitor with conductivity achieving a far greater energy density, however, it’s expensive to produce at $2000/gram. The cost to manufacture hemp’s supercapacitor version is $5,000/ton. Hemp allows the possibility for these technological advancements using hemp-based to be realized. High-performance hemp-based supercapacitors will transform the way mankind relates to energy.” according to Titan Hemp, a company centred around hemp products.

aquaponics

The most sustainable and environmentally friendly growing method on the planet

The Aquaponic process

Aquaponics is a growing technique that takes two efficient systems and combines them to work symbiotically with each other: Aquaculture is the process of farming fish (such as tilapia, koi, or bluegill) or shellfish, while hydroponics is a method of growing plants without soil. When the two are combined, you can create a nearly closed loop system that produces both plants and fish for consumption. Cannabis evolved at the base of the Himalayas, where seasonal rainfall would flood the banks and deposit high nitrate solution onto the banks. Cannabis grows exceptionally well in aquaponics, reducing grow time and increasing yield, making a healthier plant with stronger fibre. Closed loop symbiotic system, can use roots and by products from processing of hemp and crustaceans/molluscs to feed fish. Equatorial strains with tilapia will work best.

An aquaponics environment creates a habitat that optimizes growth due to microbial decomposition of organic waste causing a CO2 fertilization effect, which is ideal. The system has a high diversity of bacteria-plants share symbiotic relationships with bacteria.

This growing method produces much higher yields (up to 5 times) and halves the growing time.A double root zone will be required as with growing. cannabis requires phosphorous and potassium, which can contaminate the water.

Aquaponic setups are nearly identical to hydroponics, the main difference being the source of the nutrients for the plants. Nutrients are no longer added to a water tank–instead they are produced by waste produced by the fish. The diluted fish waste is pumped out and delivered to the roots of the plants. The roots absorb the nutrients and purify the water before it is returned to the aquarium. Fish food is the only input you’ll need, and this can be grown or purchased for the system.

The primary nutrient produced from the fish waste is nitrogen with trace amounts of other minerals. Because of this, basic aquaponic systems are effective for leafy greens, but if you’re cultivating tomatoes, cannabis, or fruit and vegetables, you’ll need to add additional nutrients like phosphorus and potassium.

Advantages of Growing with Aquaponics is Multiple Returns. If running aquaponics with consumable fish like tilapia, you’re getting a two-for-one. As your plants grow, you’ll also be raising protrient-rich fish. Generally, tilapia take between 6-9 months to reach the desired size for consumption, but speed of growth depends on the water temperature.

Aquaponics is a truly sustainable system for growing cannabis. Fish food manufactured specifically for aquaponics ensures your system is free of toxins, and provides the fish with what they need to grow strong and healthy. Again, all you need is fish food as well additional nutrients for your top soil layer, and you’ll be able to grow both healthy cannabis plants as well as fish for consumption.Aquaponics is a great method for fast-growing plants. By allowing the roots to take in high levels of oxygen, they are able to absorb more nutrients and grow quickly.Estimates show that aquaponics systems use up to 90% less water than traditional systems by recirculating water.

 

The Underlying Premise of Aquaculture

Aquaponics is a closed system cultivation technique, raising fish and plants together within the same closed-loop environment. What goes into the system stays in the system with each species taking advantage of the characteristics of the other. If done properly, the system reduces nearly 100 percent of water waste and has little impact on the local environment. 

In most commercial examples of aquaponics, farmed fish species, like tilapia, are raised in large fish tanks located close to hydroponically grown plants. The wastewater from the fish tanks circulates through the roots of the plants typically with an ebb and flow system. Sea Bio Energies has combined it into a conventional hydroponic cannabis system.

hemp and aquaponics

  • Allows for a layer conducive for mycorrhizal network development for hemp.
  • Allows the most control possible for supplementing plants in a fully recirculating system.
  • Allows for both a terrestrial and aquatic microbial root layers which increase the plant resistance to moulds and mildews.
  • Eliminates the need for expensive decoupled systems that require regular water discharge which is expensive to dispose of.
  • Maurijauna is a nitrofile, therefore it grows extremely well in high nitrate water.
  • Cannabis evolved at the base of the Himmalayas where seasonal rainfall would flood the banks and deposit high nitrate solution onto the banks.
  • Make use of a double-root zone as with growing cannabis requires phosphorus and potassium which would contaminate the water.

hemp plastic

benefits of hemp plastic

  • Biodegradable – When made with biodegradable polymers, hemp plastic is completely biodegradable, unlike regular plastics.  Plastic pollution is growing at such an alarming rate because it just keeps piling up and up. In fact, most plastic items will take up to 1,000 years before they actually decompose. Hemp plastic, on the other hand, only takes about 3 to 6 months to fully decompose — and it can be recycled indefinitely. 
  • Non-toxic – Petroleum-based plastics contain harmful toxins like BPA, which have been linked to infertility, heart disease, diabetes, obesity, and a whole slew of other negative health issues.  Hemp plastic does not contain any of these dangerous toxins at all. This makes it a much safer product for both our health and the health of our environment.
  • Renewable resource – Hemp is a renewable resource that benefits the environment instead of degrading it. Hemp crops prevent soil erosion, reduce water pollution, absorb toxic metals, and can be cultivated over and over again. 
  • Stronger and lighter – Compared to petroleum-based plastics, hemp plastic is 3.5 times stronger and 5 times stiffer. As a result, hemp plastics are more durable and have a lower chance of breaking, which also makes them safer. Hemp plastic is also much lighter than regular types of plastic.
