What other options do municipalities have for managing biosolids?
Other options include disposal in sludge incinerators and co-disposal with trash in landfills. Municipalities also have choices in the type of processes used to prepare biosolids for land application—like composting and drying. Biosolids processing and disposal is a major portion of a wastewater utility’s costs, approximately 20-30 percent of total operating cost, so treatment options are carefully examined.
