Bioenergy with carbon capture and storage (BECCS)
BECCS is used for a sustainable agriculture to address the simultaneous demands of food, energy, and environmental security.
Biomasses are converted to biogas and thence to electricity, heat and/or biomethane; stable carbon and plant nutrients are recycled to the fields by applying effluent digestate avoiding the greenhouse gases (GHG) emissions and other environmental impacts associated with fossil-based fertilisers.
Anaerobic digestion of manure, agri-food by-products, and energy crops to produce biogas and digestate (biofertilizer) that can be carried out in Africa.

Organic farming. In anaerobic digesters, about 70% of the carbon goes to biogas and 30% is transformed into more stable carbon using the digestate residue coupled with practices derived from conservation agriculture. The CO2 from the atmosphere is used for energy crop growth and introduced into the soil. The overall system therefore functions as a bioenergy with carbon capture and storage (BECCS) process.
Technology Readiness Level
Anaerobic digestion is a very scalable technology in terms of plants size and feedstock/biomasses exploiting. To implement anaerobic digestion widespread in Africa, capital and operational costs reduction and small-scale technology development are key aspects for the market deployment.
