Palm shell pyrolysis turns agricultural waste into biochar, a stable carbon-rich material that improves soil health. The process captures carbon that would otherwise be released as CO2 and creates a porous substance that can adsorb heavy metals, support microbial activity, and stabilize soil pH. This makes it useful for remediating degraded lands and for regenerative farming practices. Biochar from palm shells also boosts water retention, reduces fertilizer leaching, and locks carbon in the ground for decades. Application rates and pyrolysis temperature matter for best results. Typical rates range from 5 to 20 tons per hectare. Combining biochar with compost can further enhance soil fertility and crop yields, especially for smallholder farmers looking for sustainable intensification.
