Reverse climate change. Now
Affordable, scalable, and long term carbon sequestering is essential if we are to avoid the worst effects of climate change
Our mission is remove CO2 from the atmosphere and put it to good use improving the soil and lives of smallholder farmers
What is Biochar?
Dark Earth Carbon turns agro-forestry waste into pure stable carbon, known as biochar.
As plants grow they naturally absorb CO₂ from the atmosphere. This carbon is stored as woody biomass. Currently thousands of tonnes of agricultural plant waste is left to rot or is burnt, releasing all that carbon back into the atmosphere. Instead at Dark Earth Carbon the plant waste goes into a pyrolysis reactor turning the biomass into biochar.
Dark Earth - Clear Sky
Biochar is a powerful long lasting soil amendment. We get our name from Terra Preta, or Amazonian Dark Earth. These are places in the Amazon where people used char thousands of years ago to improve the fertility of their soils, today we can still see the benefits
Biochar improves soil quality and plant yield :
Its high porosity improves water retention, encourages the growth of microbe that build soil organic matter, and improves crop health and resilience to disease.
Its negative charge increases the storage of nutrients in the soil and provides a slow release to the plants.
Its high pH helps neutralise acidic soil, making nutrients more available to plant roots.
Scalable, cost effective carbon removal
Biochar is a safe long term storage solution for carbon. Adding biochar to soil means the carbon cannot return to the atmosphere for hundreds of years.
The dual effect of biochar as a carbon removals technology and also a soil amendment means it has multiple co-benefits.
By using a waste product we are reducing the stock of CO₂ in the atmosphere while also making a valuable soil enrichment.
Our carbon credits meet the highest certifications and ensure that all the carbon is accounted for. Biochar is an affordable carbon sequestration technique. Large scale biochar production has a key role to play to reach net zero by 2050
Smallholder farmers
Many African soils have low nutrient density due to slash and burn farming and heavy weathering.
The people who farm these lands are most at risk of the adverse effects of climate change, while simultaneously having the smallest carbon footprint by an order of magnitude.
From one application of biochar small holder farmers can;
Reduce the risk of famine
Increase resilience to drought
Improve their crop yields and their income
We work closely with African farmers to help them increase their food security by improving their soils health.
