How to Turn Auto Shredder Waste Into 60 Million Lb of Plastic Pellets
While much of the world is studying the possibility of getting any economic value out of auto shredder residue—for example, as fuel for cement kilns or power plants—Europe’s second largest scrap-metal reclaimer cranks out polyolefin and polystyrene pellets made from shredder residue at 20,000 to 100,000 lb/hr, or about 40 million lb/yr.Galloo Plastics, the recycling unit of the Galloo Group in Halluin, France, has been so successful at supplying automotive markets with its black PP compounds that it built a second auto shredder residue (ASR) recycling plant this year next to the first, inside its huge scrap yard.
