Covanta Begins Construction Of Total Ash Processing System

Breakthrough technology will increase metal recovery and create aggregate products from Energy-from-Waste ash

Morristown, NJ /PRNewswire/ - Covanta Holding Corporation (NYSE: CVA) ("Covanta"), a world leader in sustainable waste management and renewable energy, today announced that it has commenced construction of its first Total Ash Processing System ("TAPS"), with operational start-up expected in the second half of 2019. Located inFairless 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 ("EfW") facilities, recovering previously untapped value from these waste streams.

TAPS is a unique technology that 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 percent.

"We have long viewed ash reuse as a major opportunity to enhance our EfW plant operations while simultaneously opening new markets," said Covanta's President and Chief Executive Officer,Stephen J. Jones. "TAPS has tremendous potential to increase the sustainability and economics of our facilities, while generating an attractive return on capital invested in the system. I am excited about this first project and look forward to its success, which we see paving the way for additional TAPS facilities to complement our EfW portfolio."
