INTEGRATED BIOGAS SYSTEMS – Local applications of anaerobic digestion towards integrated sustainable solutions

May 2018

Biogas and anaerobic digestion can positively contribute to several Sustainable Development Goals (SDGs). This report produced by IEA Bioenergy Task 37, addresses local applications of integrated biogas concepts. Through case studies, examples of technical solutions, concepts, and strategies, which pertain to sustainable biogas production, are provided. Data has been gathered on anaerobic digestion facilities from seven countries with a focus on developing countries or countries with an emerging biogas sector which are not dependent or have little reliance on financial support. The case stories demonstrate that there is no ‘ideal’ integrated solution, as each anaerobic digestion application has different feedstocks available, constraints and end products. What needs to be considered and encouraged is adaption of exemplar systems, which suit individual situations.

Case stories:

  • Covered anaerobic pond treating piggery waste in Australia
  • Commercially viable biogas from food waste in Australia
  • Biogas from piggery waste in Brazil
  • Biogas from sugarcane vinasse in Brazil
  • Biogas technologies for sewage treatment from institutions in Ghana
  • Biogas support programme in Nepal
  • Co-digestion of waste materials with high fat, oil and grease content in New Zealand
  • Biogas from prison sewage in Rwanda
  • Biogas plants for rural families in South India
