Biochar: Natures ‘black gold’ for soil, crops & climate
Harnessing the power of ancient ‘terra-preta’ with our high-grade, sustainable Biochar nutrient-rich with natural materials.
Great for the soil, good for the planet
Our commitment to sustainability goes beyond energy production. As a valuable byproduct of our biomass energy-producing facility, our premium biochar is a powerful tool for enhancing soil health, decarbonising concrete manufacture and combating climate change.
Rich in carbon and produced through a clean, efficient process, ReGenEarth biochar improves soil fertility, boosts water retention, and promotes plant growth while sequestering carbon for the long term.
Whether for agricultural, horticultural, construction or environmental applications, our biochar offers a natural solution that supports both productivity and planetary health.
Working in partnership with…
We’re excited to introduce ONNU as our trusted partner in the production of biochar from our existing renewable feedstocks. Together with ONNU, ReGenEarth is pioneering innovative solutions that harness the power of biomass to create cleaner, more sustainable energy.
This collaboration strengthens our commitment to reducing carbon footprints and advancing renewable energy technologies, paving the way for a greener, more sustainable future.

What is Biochar & why does it matter?
Biochar is a stable, carbon-rich material made by heating organic biomass in a low-oxygen environment, a process known as pyrolysis. It’s an ancient technique with modern benefits:
- Biochar stores carbon long-term
- Extends soil life by decades
- Boosts yields by up to 30%
- Enhances soil weather resilience
- Supports renewable energy
Perhaps the most important element is that it offers a powerful solution for carbon sequestration at scale. In fact 88% of all carbon currently sequestered through engineered methods has been achieved through biochar, according to CDR.FYI.
ReGenEarth’s vision for a ‘circular carbon economy’
ReGenEarth is proud to be working with RER and Woodtek on their mission to transform anaerobic digestion sites into cutting-edge biochar production hubs. This partnership is turning organic waste into a commercially valuable product while drawing carbon from the atmosphere and locking it into the land.
By integrating biochar into the circular economy, we’re restoring soil, reducing emissions and significantly increasing yields, meaning more from less, which enables the sustainable long term growth model for profit. Building a sustainable, profitable model for climate-focused investment.

Biochar: Green Bond Investors Event
IET London | June 10th, 6pm
An evening of action & opportunity
RGE launched a groundbreaking initiative to turn agricultural waste into one of the most powerful natural solutions to climate change: Biochar. More than an event, this marked a pivotal opportunity for forward-thinking investors to get involved in scaling a solution that captures carbon, restores soil health, and creates lasting value. With global warming accelerating, the need for bold, scalable action has never been more urgent.
If you couldn't make it, you can watch the full presentation here, or contact us for more details.
Let’s turn innovation into impact, together.

The benefits of biochar

Natures carbon storage solution
Biochar locks carbon in the soil for hundreds to thousands of years, making it one of the most effective and scalable methods of permanent carbon removal available today.

Extends soil life by decades
Biochar naturally regenerates soil health and structure, extending its productive life by decades while improving fertility, moisture retention, and microbial activity.

Boosts agricultural yields by up to 30%
Applied to soil, biochar can improve agricultural yields by up to 30% by enhancing nutrient retention, soil structure, and microbial activity.
