Metals Recovery & Recycling

Our waste-to-energy facilities recover tens of thousands of tons of ferrous and non-ferrous metals every year that would otherwise go to a landfill, directly reducing both greenhouse gas emissions and the need to mine more raw materials.

When post-recycled waste is processed, over 90 percent is converted to energy. With the remaining 10 percent ash residue, we recover and recycle ferrous scrap metals, such as iron and steel, and non-ferrous scrap metals, such as copper and aluminum. Last year, we recovered and recycled 150,000 tons of ferrous and non-ferrous scrap metals that would have otherwise ended up in landfills.

While these systems have been operating at our waste-to-energy plants for decades, we continually explore advances in metals recovery technology to increase metal recycling rates. Our facilities complement local recycling programs and foster a higher overall recycling rate than communities without waste-to-energy plants.

We recently implemented advanced metals recovery systems at our Putnam and Shrewsbury monofills that enhance our ability to save valuable resources and reduce the use of energy to produce new metals. Our Putnam Monofill now also features a central upgrade facility. In 2014, Wheelabrator formed a North American-based joint-venture company with Inashco BV — Eco Recovery Solutions — dedicated to maximizing the recovery of recyclable ferrous and non-ferrous metals from the waste-to-energy process.

Inashco’s patented and proprietary technology enhances metals recovery at Wheelabrator’s facilities, extracting pieces of scrap metal as small as 0.2 mm in size. A single installation is capable of processing over 500,000 tons per year of ash residue, reducing the volume by as much as 10 percent by weight.
