A no-nonsense guide to farm digesters, providing a wealth of useful information for anyone interested in installing one.
Most people have heard of farm digesters and how they can produce renewable energy from cattle slurry and other organic waste. But digesters can do a lot more than that. They transform what is often considered problematic, noxious waste into fertiliser, massively reducing our dependence on fossil fuel-based artificial fertilisers. They produce saleable compost as a by-product. They minimise water pollution and enable organic waste to be effectively recycled. Digesters let us run farms more economically, and make our energy supplies and our food production more sustainable.
Written by farm industry expert, Jonathan Letcher, Farm Digesters provides practical information on how digesters work, how to set-up a farm digester programme, and commercial products from digesters. Jonathan also discusses why we need farm digesters and evaluates their pros and cons, sharing valuable insights into the existing barriers that need to be overcome and providing a clear overview of their main technical issues.
This straightforward book is perfect for farmers looking to become more sustainable and save money.
