Image caption: The Future is Biogas

Abstract: Anaerobic digestion (AD) is fermentation that takes place in the absence of oxygen. Organic material is broken down and converted into biogas which can be burnt to produce electricity and heat, or as transport fuel. This picture shows the silage store, gas pipes, the digester and tractor in action. The research is about measuring energy use, production, and greenhouse gas emissions from AD systems. This is done through direct measurement of operations and environmental life cycle assessment modelling. The image was taken at an AD facility in Norfolk whilst on a site visit. AD has multiple benefits including renewable energy generation, efficient waste management, and organic fertiliser production. AD has the potential to reduce greenhouse gas emissions from agriculture, reduce fossil fuel dependency, diversify farm businesses, and improve soil quality. This research aims to quantify and assess these benefits against potential impacts.
