Energy recovery and waste treatment with floating biodigesters

Purpose

Improving the sanitation of water-based and floodprone communities through floating, small-scale biodigesters where excreta is converted into biogas for energy and into fertilizer.

Activities

This project will develop and trial floating and small-scale biodigesters to convert human and animal waste to biogas for energy and treated waste for fertilizer, while improving the sanitation and public health outcomes of communities living in challenging environments such as water-based and floodprone communities.

Research is covering 4 main areas: a) waste treatment effectiveness and related parameters, b) biodigestion operation and gas production c) system physical performance and material requirements, d) community acceptance evidence.

Objectives

1) Develop, test, improve and document small scale and floating biodigesters and required supporting systems (flotation, inlet systems etc) to allow effective operation in floating and flood-affected villages. 2) Collect supporting data on operational performance under controlled conditions 3) Conduct preliminary practical field trials for community uptake and acceptance feedback and evidence. 4) Integrate biodigesters into holistic development programs especially for sanitation, health,
