WASE provides decentralised sanitation for underserved communities using a circular economy approach to the treatment process. So we can produce value-added products to offset the cost of sanitation and provide a clean and safe wastewater treatment solution. Our system will enable us to create a hydrogen based biogas to be used for cooking or generate electricity. The production of a clean cooking fuel can help reduce deforestation and indoor air pollution in communities where biomass is the primary source of energy for cooking. We can also recover water for irrigation and nutrients within the waste that can be converted into a fertiliser increasing crop yields and the reliance on imported fertilisers. Our system is modular allowing easy scalability and adaptability to tailor the system to the local environmental, social and economic needs.
