Farm digesters are best known as a means for producing biogas. However, anaerobic digesters are much more beneficial, because they also: * Greatly reduce pollution, smell and pathogens from livestock farm waste. * Reduce greenhouse gas emissions. * Reclaim nutrients for re-use, minimizing the need for artificial fertilizers. * Can produce fibre from animal waste, for use as * compost. They represent a significant way to make both our energy supplies and our food production more sustainable whilst enabling us to run cost-effective farms. This no-nonsense guide to farm digesters provides a wealth of useful information for anyone who wants to know more. The book covers: * Why we need farm digesters * How they work * The benefits of farm digesters * How to set up a farm digester programme Accessibly written, this book is a must-read for anyone who is running a farm, cares about creating a sustainable future, or is involved in planning for agriculture.
