Covanta Holding Corporation announced that it has commenced construction of its Total Ash Processing System with operational start-up expected in the second half of 2019. Located in Fairless Hills, Pennsylvania, adjacent to Covanta's existing metals processing facility, the first TAPS plant is designed to process over 400,000 tons of ash from multiple Covanta Energy-from-Waste facilities, recovering previously untapped value from these waste streams. TAPS separates the combined ash from EfW facilities into its component parts. This enables increased recovery of small metal fractions and the recovery of aggregate for reuse as construction material, reducing the volume of ash requiring landfill disposal by as much as 65%.
