Biogas Chemistry
The chemistry and biochemistry of biogas.
Biogas is produced by anaerobic fermentation of organic materials (biomass) such as compost, organic waste, sewage sludge, manure, plant residues etc. Biogas is particularly suitable for energy production in so-called biogas plants.
Chemically, biogas is a flammable gas. It is composed very differently depending on the substrate employed and technical workup.
As main constituents generally occur methane and carbon dioxide. Other components are nitrogen, oxygen, hydrogen, ammonia, hydrogen sulfide and water vapor. The interfering gases in the crude biogas (H2S, NH3 and CO2) are deposited prior to combustion.
The production of biogas is a microbial process that occurs in several stages. Starting materials are the carbohydrates, fats and proteins in the biomass. These are converted by the microorganisms through various metabolic pathways in biogas - in absence of oxygen (anoxic conditions; for example, anaerobic digestion).
The following list includes online available information on the chemistry and biochemistry of biogas.

Biogas from Waste and Renewable Resources
The leading book on the market just got better: With ist unique approach covering all aspects of setting up and running a biogas plant, this new edition has been expanded to include recent advances in biomass processing.
The author is a key player in the field, who has designed numerous small- and industrial-scale biogas plants, and who is also a long-time lecturer on biogas production, thus combining didactical skill with real-life expertise. As such, he covers both the biological and technical aspects of biogas generation. The full range of biogas substrates and processing modes is explained, from agricultural and industrial waste to marine algae and sediment. On-site use of biogas for conversion into electricity, fuel and heat is also discussed, as are safety and regulatory issues. Many real-life examples of European biogas plants already in operation illustrate the contents, as do numerous schemes, diagrams and summary tables.
For this new edition, biogas analytics and quality control required for feeding biogas into natural gas networks are included, as is a completely new chapter on the microbiology of biogas-producing bacterial communities.
