Abstract:During the past 50 years, greenhouse gas (GHG) emissions have increased more than five fold and the corresponding level of GHGs in the atmosphere has almost doubled. Greenhouse gases impede the radiation of heat from the earth back into space, resulting in increased temperatures on the earth's surface and contributing to the greenhouse gas effect. Greenhouse gas emissions have become a significant concern and are increasingly being measured and evaluated when determining the long-term sustainability of a treatment system. Wastewater treatment, being one of the largest consumers of energy for cities and municipalities, is assuming increased importance as a potential avenue for reducing the overall GHG inventories of a community. A number of governmental organizations are now requiring inventory of GHG as a first step in control and/or reduction of their emissions. These organizations include both international (IPCC and WIR) and federal (USEPA) and state (CCAR). Greenhouse gas emissions are also becoming subject to gas trading credits, similar to other air emission programs. This paper focuses on GHG emissions from biosolids processing operations at a wastewater treatment plant (WWTP), providing a methodology that can be used during the strategic planning process for comparing the sustainability of various treatment options in terms of environmental impact.
