Coconut shell waste can be turned into biochar through pyrolysis, creating a stable carbon product that improves soil health and locks away carbon for decades. The process heats shells in an oxygen-limited environment, producing biochar, syngas, and bio-oil. The syngas can power the reactor, reducing external energy needs. Biochar's porous structure helps soil retain water and nutrients, reducing the need for irrigation and chemical fertilizers. It also provides habitat for beneficial microorganisms. Because biochar remains stable in soil for centuries, it offers long-term carbon storage and can generate carbon credits under recognized standards. This model is especially viable in coconut-producing regions of Southeast Asia, Africa, and Latin America.
