At the Remondis site in Röstanga, Sweden, HDPE pipes and other plastic waste from production are transformed into new raw materials using a WEIMA PowerLine 2500 shredder and a subsequent washing plant. Just 50 km away, a WEIMA S7.20 single-shaft shredder reduces large and heavy PE chunks in a Remondis recycling plant in Staffanstorp. The use of powerful WEIMA shredders enables effective processing of even the heaviest materials, highlighting the sustainability and efficiency of Remondis recycling processes.
Remondis in Röstanga: The Recycling Specialist
At the Röstanga site, post-consumer HDPE (High-Density Polyethylene), including thick-walled pipes and other plastic waste, is shredded, washed, and then sold as regrind to customers who manufacture new products from it. Remondis needed a robust machine to shred the materials: “It’s very heavy and large material that we shred. The demands on the shredder were high: it had to be particularly stable and weather-resistant, as it would be set up outdoors,” says Per Persson, site manager in Röstanga.
The WEIMA PowerLine 2500 single-shaft shredder was convincing. The decisive factors were WEIMA’s robust design, superior machine equipment and ease of maintenance. Thanks to the hydraulic inspection flap, routine maintenance – whether turning knives, optimizing the cutting gap or removing foreign matter – is greatly simplified.
Material Throughput of Five Tons Per Hour
To shred the robust pipes to a homogeneous particle size of 40 mm, the shredder is equipped with a special rotor. This rotor has a working width of 2,500 mm and a diameter of 800 mm. With the torque-strong hydraulic drive from Swedish market leader Hägglunds Bosch Rexroth, a throughput of approximately five tons per hour is achieved when shredding HDPE pipes. Additionally, a winter package for the hydraulics was supplied for the cold Swedish winter days.
After shredding, the plastic flakes are transported by conveyor belt to a bunker. In another hall, the shredded plastic is cleaned, dewatered, and packed into big bags in a washing plant. The washed plastic flakes are then sold and serve as raw material in the form of regranulate for new plastic products.
