The document discusses anaerobic digestion (AD) as a way for farms to profitably address climate change, energy security, and food security issues. AD involves breaking down biodegradable material to produce biogas and digestate. The National Farmers Union (NFU) supports AD as it can help reduce greenhouse gas emissions from livestock farming and provide farms with income from energy sales. The NFU calls for a regulatory framework that does not inhibit smaller, on-farm AD systems and aims to deploy 1000 farm-based AD plants and 100 larger waste-licensed AD facilities by 2020 to contribute to renewable energy and environmental goals.
