Eriez white paper looks at metals in EfW ash

Erie, Pennsylvania-based separation technologies equipment maker Eriez says it has produced a white paper highlighting the technology it has created to improve metal recovery in energy-from-waste (EfW) applications.

The company says the four-page publication, created in response to the growing need to recover more metals from bottom ash in EfW applications, describes how its P-Rex Scrap Drum “can help maximize ferrous recovery.”

The paper, titled “P-Rex Distinguishes itself in Energy-from-Waste Applications,” has been written by Eriez Director of Heavy Industry Darrell Milton, and is available on this page on the company’s website.

The paper offers case studies and background information, including that one report determined all United States EfW facilities combined are recovering more than 700,000 tons of metals for recycling each year

 If some 250 million tons of municipal solid waste (MSW) is still going to landfills every year, and if approximately three percent of that stream is metal, then 7.5 million tons of recoverable metals are lost annually, according to Eriez.

Eriez says the strength and revolutionary design of its P-Rex Scrap Drum Magnet “allows for the highest level of ferrous metal recovery possible from bottom ash.” The company cites “advanced engineering and rare earth magnet technology [that] give P-Rex the advantage in critical performance areas: superior edge-to-edge separation, no ‘transfer point’ drop in magnetic force and no decline in performance due to heat.”

The paper includes a variety of photos and cutaway drawings designed to enhance readers’ understanding of how the equipment operates.

“We developed this white paper because even some of the largest and most successful EfW facilities are missing substantial ferrous recovery opportunities,” says Milton. “Our aim as a recycling industry leader is to educate professionals about our cutting edge solutions--such as P-Rex--which give users the ability to cash in on the significant revenue stream available through greater recovery of ferrous metals.”
