The World Biogas Summit 2021


Humans directly or indirectly generate over 105 billion tonnes of organic wastes globally each year, all of which release harmful methane and other greenhouse gas emissions directly into the atmosphere as they decompose.

These organic wastes include food waste, sewage and garden wastes, food and drink processing wastes, and farm and agricultural wastes. Today only 2% of these are treated and recycled.

Over the first decade in the atmosphere one tonne of methane is the equivalent of 86 tonnes of CO2. If we do not cut methane emissions from organic wastes immediately, then climate catastrophe is unavoidable.

By managing all organic waste as important bioresources through anaerobic digestion and the generation of biogas we can cut global GHG emissions by 10% by 2030, starting now. Untreated organic wastes are a problem. Anaerobic digestion not only solves this problem, but also delivers the greatest value from these bioresources.


This Summit is about how to efficiently capture the 105 billion tonnes of organic wastes produced annually around the world, recover the valuable gases and nutrients they contain and recycle them into clean energy and natural fertilisers. More information here.


Hear from thought-leaders and experts from across the globe, share knowledge and best practice, learn from others’ experiences and agree on the key strategic approaches necessary for a healthy, sustainable future. More information here.
