American start-up Applied Carbon has developed an agricultural robot that captures CO2 by transforming agricultural residues into biochar - a substance capable of storing carbon for decades.

Heat that biomass up without fully consuming it and it turns to nearly pure carbon known as biochar, which farmers soak in compost or fertilizer to “charge” it with nutrients, then add to ...

The Eastern Washington company takes crop and forestry wastes, applies a patented technology to convert the organic debris into biochar, and uses that material to more efficiently grow the next ...

The company invested millions of dollars to receive up to 10,000 tons of carbon dioxide removal credits through the production of burnt organic material, or biochar, which offsets emissions the ...

Improve your soil by making biochar in the ground. DIY biochar enhances nutrient availability and also enables soil to retain nutrients longer. Last year, I committed one of the great sins of ...

Then the farmer makes several more passes spreading other material in different combinations: bone-white limestone dust, rich black biochar and chicken litter compost that reeks of ammonia.

Based on European emissions of about 1.1 gigatonnes of carbon per year, we estimate that biochar could offset around 9% of Europe's emissions. We suggest that biochar should be added to the ...
