Rice husk is an untapped source of biomass for carbon sequestration. We transform husk into biochar, fixing carbon into the soil for hundreds of years.
Turning agricultural waste into charcoal is an age-old farming practice to regenerate soils and keep the carbon balance in check, however industrialisation has disrupted this cycle and now biomass is burnt for fuel with emissions returning to the atmosphere. We have reactivated this ancient practice and using pyrolysis technology transform the CO2 absorbed by the rice plant from the atmosphere into a stable form of carbon (as biochar). The IPCC now recognises biochar as one of the key carbon sequestration solutions that needs to be scaled up to solve our climate emergency. Following the latest IPCC guidelines for every tonne HUSK biochar we remove 1.33 tonnes of CO2 from the atmosphere.
Our mission is to put a million tonnes of carbon back into the soil.
The conservative estimates for a liveable future are that we need to draw down 100 Gigatonnes of CO2 by 2100, in other words undo 20 years of emissions. If just 10% of the rice husk that is produced globally was transformed into biochar, 7 million tonnes of CO2 could be sequestered every year. We have created a scalable carbon sequestration solution that regenerates soils, improves farmers yields, reduces the use of fertilizers and fuel for pumping water and boots smallholder incomes.
A Virtuous Cycle
Carbon Removal Credits
We offer individuals and companies a practical way to reduce their carbon footprint and support smallholder farmers. We issue Carbon Removal Credits (CRCs), based on the latest IPCC guidelines. Purchasing HUSK CRCs is a simple and meaningful way to take action against climate change today. The revenue generated from the credits helps us keep our products affordable for farmers. Our tried and tested model of one pyrolysis unit in a medium sized rice mill will have the capacity to remove 16.000 tonnes of CO2 from the atmosphere in 10 years.
