- The city of Kingston partnered the Aslan Group to develop a new and innovative system the first of its kind in the world for managing wastewater treatment plant residuals in an economical and environmentally sound manner. Waste "biogas" is captured from the plant's digesters and utilized as the only required fuel to turn 10 wet tons per day of municipal wastewater sludge into one ton per day of an EPA recognized pelletized usable "biosolid." The biosolid is distributed free of charge for use as a lawn fertilizer or furnace fuel, which costs less than the previous practice of landfill disposal. Also, methane gas is efficiently utilized within the process as a fuel and since very little methane is flared, oxides of nitrogen and other pollutant emissions have been reduced.
