Periodic Products’ polymer technology can also be used for the recovery of other metals in technogenic sources of metals, such as incinerator ash. In 2015, more than 90 waste-to-energy (WtE) facilities operating in 24 states processed more than 26 million tons of municipal solid waste. The two types of ash, bottom ash and fly ash, produced during WtE generation are frequently combined to reduce the leaching potential of the component metals. 

While there have been numerous investigations into the possibility of using WtE ash as a source of metals, including copper, lead and mercury, a cost-effective has not been found. Using its proprietary extraction technology and patented polymer-based metal isolation procedures, the Company has successfully isolated copper and lead, the major metal contaminants, from 80-year-old municipal incinerator ash and contaminated soils. Based on initial projections, the cost for our process of extraction and isolation is approximately 30 to 40% of the current market price for these metals.
