None of this discourages Miriam Holsinger, co-president and chief operating officer of Eureka Recycling, a nonprofit recycler in Minneapolis.
Each year, Holsinger’s materials recovery facility, or MRF, receives roughly 100,000 tons of stuff tossed by Minneapolis, St. Paul and surrounding communities, including car parts, bowling balls, diapers and other items. Yet the vast majority ends up as new products, thanks to a gauntlet of machinery, including massive ballistic separators and optical sensors, that sorts more than 1,000 items per minute. Reclaimers — the next stop, where bales are washed, shredded and processed — pay for these raw materials.
