DeCo! - Decentralized Composting for Sustainable Farming and Development

Increasing crop yields by promoting an organic fertilizer service
2010 SEED Award Winner Waste Management Tamale, Ghana

DeCo! offers a composting service to smallholder farmers in Northern Ghana. DeCo! follows a low-tech approach and aims for scalability. The plants are run by highly educated local managers and DeCo! offers part-time work for local people during the off-farming season. DeCo! is a social business convinced of the benefits of compost, which addresses soil degradation and its associated local challenges by providing a composting service to smallholder farmers. Local people sell farm and household waste biomass to DeCo!. At a decentralized composting plant, the biomass of 3-6 surrounding villages is gathered and composted. DeCo! employs only local people who have no alternative work during dry season. the compost is then sold to local farmers who apply it before the sowing period.
