"Anaerobic digestion, or biodigestion, involves the microbial degradation of organic materials in an oxygen-free environment. Feedstocks for anaerobic digestion include livestock manures, crop residues, culled fruit and vegetables, food waste, and other organic by-products. The process produces renewable energy in the form of biogas (which is mostly methane) and a nutrient-rich digestate that can be used as a biofertilizer instead of commercial fertilizers."

-- Dr. Ann Wilkie, Professor of Bioenergy and Sustainable Technology in the Soil and Water Science Department at the University of Florida

  1. 2001-01-01 When organic material decomposes under anaerobic conditions, it produces biogas which is a mixture of methane (CH4) and carbon dioxide (CO2) with small quantities of hydrogen, nitrogen, carbon monoxide and other compounds. Biogas can be used as a fuel source for cooking, heating, producing light...

  4. This study investigated the main factors influencing digester temperature and methods to reduce heat losses during the cold season in the subtropics. Four composite digesters (two insulated and two uninsulated) were buried underground to measure their internal temperature (C) at a depth of 140 cm...

  7. Biogas is a clean cooking and lighting fuel that can be produced at varying scales; from small household systems to large-scale commercial plants producing several thousand cubic metres a day. Biogas can be used for electricity generation, heating, cooking, process steam and powering farm...
  8. 2016-04-12 When the organic matter decomposes in the absence of oxygen , it produces gas called biogas . This gas is a mixture of methane (CH4) and carbon dioxide (CO2) with small amounts of nitrogen , hydrogen, carbon monoxide and other compounds. Biogas has multiple uses . To produce and capture the...

  10. This article is from ECHO Asia Note #19 It iscompletely possible to run a diesel engine on biogas; however, a number of considerations must be taken into account before it may be considered a serious option in a development program. This article will explore some key considerations when...
  11. In China’s rural areas, most villages do not have electricity, and commercial fuels like kerosene and coal are expensive. Thus the rural population still relies heavily on biological sources of energy. Fuelwood and crop residues (mostly straw) account for 80% of rural household energy use and 54%...
  12. Opportunities for Practice Change are examples of actual activities focusing on changes in manure policies and manure management practices which have or will have apositive impact on the livelihoods of farmers and theenvironment.

  14. AccessAgriculture Video Zero-grazing is where fodder is cut and carried to cows which are kept in stalls. It is suited to where land is scarce. When the manure that the cows produce is mixed with water it can provide the fuel for a biogas plant. The mix of methane and carbon dioxide can be used...
  15. Biofuel Research Journal (BRJ)is an Open Access journal withcompletely Free-of-Charge publication policy. BRJ publishes high-qualityoriginal articles, review articles, case studies, book reviews, short communications, and hypotheses on the fundamentals, applications, processing, and management of...
  16. Abstract, Biofuel Research Journal, 2016 One of the greatest challenges facing the societies now and in the future is the reduction of green house gas emissions and thus preventing the climate change. It is therefore important to replace fossil fuels with renewable sources, such as biogas. Biogas...
