Renewable Energy & Biochar
Crop residue is burned in the open across northern Ghana every year. Turned into biochar it improves soil, and the process itself produces usable heat.

The work covers small-scale biochar production from groundnut shells, maize cobs and rice husk, improved cookstoves, and solar drying and pumping for smallholders.
Biochar is attractive here because it solves two problems at once: it takes a waste that is currently burned and returns carbon to soils that have very little organic matter left in them.
How it is used in communities
Solar drying and pumping
Cutting post-harvest loss and extending the growing season.
Soil amendment trials
Measuring what biochar actually does to local soils over several seasons.
What has changed
Better soil
Organic matter returned to soils that had been stripped of it.
A product to sell
Groups producing biochar for sale as well as for their own fields.
