Biogases are emitted into the atmosphere through a variety of products. Often, these biogases contain siloxanes, non-toxic compounds that are frequently added to consumer products, such as detergents, shampoos, deodorants (to improve texture and feel), cosmetics, paper coatings and many textiles. While some siloxanes quickly volatilize into the atmosphere, others remain present and can be found in the biogas emitted from wastewater treatment facilities and anaerobic digesters.

What are siloxanes?
The generation of electricity from municipal digesters and land fill is of increasing interest, as the biogas generated is a form of renewable energy. Organosilicon compounds are often present in products such as shampoo and cosmetics, as well as industrial products and lubricants, and they move into land-fill. These volatile compounds find their way into land-fill or digester gases as siloxanes.
