The EPA has developed the Waste Reduction Model (WARM) to help solid waste managers estimate greenhouse gas (GHG) emission reductions from several different waste management practices. This model is useful for high level analysis but breaks down when applied to specific local systems. This paper will discuss new work currently being done by HDR to provide more reliable analysis of local conditions. This capability is of growing importance given the emergence of national carbon regulations which will require solid waste managers to develop greenhouse gas reduction strategies for their local systems.

This review analyses methane emissions from dairy farms due to enteric fermentations and use of different feed additives as a strategy to control them. CH4 is a product that forms during the fermentation of food in the rumen of ruminants and on average represents a 7% loss of the energy ingested by the animal. CH4 is also a potent greenhouse gas. Various approaches have been studied in many countries with the aim of reducing methane emissions of digestive origin like the use of biotechnologies to modify the microbial ecosystem. This include selection of rumen micro-organisms through the elimination of protozoans or the inoculation of exogenous bacterial strains, vaccination against methanogenic micro-organisms, etc. or use of new food additives like plant extracts, organic acids, etc. and are theoretically promising paths. Their application is however still not known because trials are being performed mainly <em>in vitro</em>. This article focuses on reducing methanogenesis by adjusting the composition of the feed distributed to animals.
