Refers to the biological degradation of either sludges or solid waste under anaerobic conditions, meaning that no oxygen is present. In the digestive process, solids are converted to noncellular end products. In the anaerobic digestion of sludges,...

Methane digesters are systems that use anaerobes to produce methane through fermentation. Methane is a main constituent of natural gas and can be readily substituted for that nonrenewable resource. The anaerobes used in methane digesters are...

A process whereby organic waste material is broken down in a closed vessel in the absence of oxygen. The process involves the production of CARBON DIOXIDE and METHANE (the latter can be used as a fuel) as well as solids and liquors that can be recycled...

Anaerobic digestion is a process in which microorganisms break down biodegradable material in the absence of oxygen. The process is widely used to treat wastewater sludges and organic wastes because it provides volume and mass reduction of the input...

MARK MOSER founded Resource Conservation Management, Inc. (RCM) in 1982, focusing on anaerobic digestion of agricultural manures (see "Anaerobic Digestion Advances," February, 2000). Based in Berkeley, California, RCM specializes in designing systems that produce methane and electricity. "We design the systems, supply certain equipment,...

An assortment of biomass recovery projects illustrates the wide range of initiatives currently in progress. AS preparations accelerate for the third annual BioCycle Renewable Energy From organics Recycling Conference to be held in Minneapolis, Minnesota this November, here is a sampling of anaerobic...

Home-buyers of tomorrow could find themselves walking across floors made from manure. Researchers at Michigan State University and the U.S. Department of Agriculture insist it's no cow pie in the sky dream. They say that fiber from processed and sterilized cow manure could take the...

Home-buyers of tomorrow could find themselves walking across floors made from manure. That's no cow pie-in-the-sky dream, according to researchers at Michigan State University and the U.S. Department of Agriculture.They say fiber from processed and sterilized cow manure could take the place of sawdust in...
