Our model

We work in partnership with organic rice mill cooperatives to produce biochar products for smallholders and renewable energy to improve productivity at the mill.

Rice farmers have  made biochar for centuries, however due to industrialisation no longer have access to the husk. We apply state of the art technology to this age-old practice, installing integrated biochar and biofuel systems at the mills where the husk is accumulated.

We use an abundant agricultural by-product, to make the biochar affordable, and use existing rural distribution networks to reach the most remote farmers. We train farmer leaders to train their peers  in effective application.

Our climate impact is positive as we avoid the greenhouse emissions from the usual practice of burning rice husk or allowing it to decompose. Using a combination of @Flox and pyrolysis technology we fix the carbon in the husk and put it back into the soil, where it remains stable for hundreds of years.  Converting biomass into biochar has been recognised by the IPCC as a viable and scalable strategy for sequestering carbon.  We estimate that for every tonne of biochar we produce, we offset 1,83 tonnes of carbon.
