GWG takes over collection and processing
as a hub
So that HBCD-containing waste can be fed to the processing plant, this must be first properly collected, pre-treated and transported to the plant. GWG, part of the Hagedorn group of companies, is currently one of only two hubs in Germany that will undertake the collection and processing from one source in future.
“From September 2020, we are starting with the collection and processing of HBCD-containing polystyrene for PSLoop,” explains Frank Kramer, Managing Director at GWG. “With this cooperation, we are offering our customers all over Germany one of the first truly sustainable waste stream management systems for this waste.”
From the construction sites, the HBCD-containing polystyrene is transported to GWG’s 8000-m² treatment facility. It is important that the material is already separated from other impurities such as building rubble, wood or roofing felt during removal at the construction site.
Any remaining impurities are removed at GWG by hand, with an excavator and/or mobile air separators. With innovative technology, the (almost) unmixed material is compacted into easy-to-handle blocks. First, an efficient primary crusher with two shearing knife shafts shreds the HBCD-containing polystyrene into pieces measuring 20 – 50 mm. A fully automatic mobile press enables the production of highly compacted blocks (volume reduction up to 30:1). These dimensionally stable blocks are stacked on pallets and, after notification by GWG, they are transported to the Terneuzen plant in the Netherlands.
“So that PSLoop becomes a success all over Europe, we need strong and reliable partners like the Gütersloh Recycling Centre,” explains Alix Reichenecker, Circular Economy Manager at PSLoop. “With their logistics network and their expertise in waste disposal, they ensure that the material is collected, processed and delivered to us with acceptable quality.”
