| Bioslurry for improved soils and yields in East Africa | This poster presents the agricultural benefits of biodigesters beyond biogas. Bioslurry and Bioslurry Enriched Compost (BEC) improve soil health, boost crop yields, and reduce erosion. Based on field surveys, desk reviews, and modelling studies, the findings show that bioslurry and BEC improve soil chemical, physical, and biological properties. Long-term application increases soil organic matter, reduces erosion (up to 52% in Kenya and 34% in Uganda in maize systems), and gradually lowers the required application rate due to ongoing nutrient mineralisation. It was presented at the RAMIRAN Conference in 2025. | |
| Bioslurry for improved soils and yields in West Africa | This poster presents the benefits of biodigesters beyond biogas, focusing on bioslurry and Bioslurry Enriched Compost (BEC). These organic fertilizers improve soil health, increase crop yields, and reduce erosion in West African cropping systems. Modelling shows that 15 years of bioslurry application could reduce soil erosion by 50% in Burkina Faso, Mali, and Niger in tomato systems. Long-term use builds soil organic matter, gradually releasing nutrients and lowering the need for repeated applications. It was presented at the RAMIRAN Conference in 2025. | |
| The biodigester’s business case | Explain the added value of bioslurry and bioslurry enriched compost for Ugandan, Kenyan and Sahelian farmers. Bioslurry and Bioslurry Enriched Compost boost your harvest and cut costs on chemical fertilisers. This delivers a quick return on investment in just 1 to 3 years. | |
| Biomethane potential of urban food waste in Africa | Expansion of Anaerobic Digestion in Africa is limited by high investment costs and concerns on feedstock availability. There is a huge untapped potential in urban and household waste including sewage sludge which have significant biomethane potential due to their high organic content, moisture level and biodegradability. This poster, exploring the biomethane potential, estimated the biomethane potential of urban food waste in Africa at 24 billion cubic meter (BCM). | |
