Bay Area Clean Water Agencies report that as of 2007, the Bay Area generated about 158,000 dry tons of biosolids annually. Because biosolids production largely depends on regional population, the amount of biosolids generated in the Bay Area is expected to increase as the region’s population continues to grow.
Local, State and Federal regulations are becoming increasingly stringent and restrictive of the current biosolids management practices of soil amendment and landfill cover. Without a biosolids to energy solution, further restrictions on these traditional biosolids management options will mean increased air pollutants and additional costs to ratepayers as biosolids are transported greater distances for disposal.
