The Biogas/ Biofertilizer Handbook

At a glance..

The subject of this book is one approach to building and operating biogas systems, not biogas digesters. Biogas systems include raw material preparation, digesters, separate gas storage tanks, use of the gas to run engines, and the use of the sludge as fertilizer.

The details..

The Biogas/Biofertilizer Business Handbook is an essential resource for anyone interested in developing biogas systems. The book covers all aspects of the process from raw material preparation, digesters, separate gas storage tanks, use of the gas to run engines, and the use of sludge as fertilizer. Written by Michael Arnott with invaluable advice from experts in this field such as Dr. Alfredo S. Mercado; Dra. Lolita L. Mercado; Engineer Patricio M.Bael Jr.; Paul Taleon; Erdie Mira among others.

Arnott's approach focuses on building and operating biogas systems that are profitably operated as cooperatively or privately owned labor-intensive small businesses which can make a rewarding return on investment while contributing to the wealth of their communities through meeting local fertilizer and fuel needs using local resources and skills.

One key aspect covered in detail within this handbook is raw materials used in these processes including animal waste (manure), plant waste (shredded/ground/pulped) along with digester slurry mixed with water or liquid portion of used slurry having 8-10% solid content & pH level being neutral/slightly base(alkaline). Slurry should have carbon-nitrogen ratio around 30:1 without any floating matter/dirt/sand present.

Overall, The Biogas/Biofertilizer Business Handbook offers practical guidance for those looking into starting up their own business ventures based on appropriate technology solutions like biogas system development.
