According to the Veolia Group’s growth plans for 2017, annual sales in the plastics recycling segment are expected to increase fivefold – from around €200 million to approximately €1 billion. There is a spirit of optimism and willingness to invest in the circular economy. According to market observers, the industry in general is booming and it is receiving additional impetus from the EU’s circular economy package and plastic strategy. EU Commission Vice-President Frans Timmermanns warns that in 2050 there could be more plastic particles than fish in the world’s oceans, pointing to the catastrophic consequences for the ecosystem if action is not finally taken. As consumption and waste volumes are expected to increase, more processing capacity will be needed for post-consumer plastics.
A very important system component – the best prerequisite for automatic sorting
At the Veolia Umweltservice West GmbH site in Morschheim, over 6,000 tons of commercially produced LDPE film waste arrive annually for sorting. The Micromat 2000 BW proves to be a very important system component. The shredding performance of the tried-and-tested Lindner model series is key to ensuring that very high sorting qualities can be achieved in the downstream automatic sorting process with NIR equipment from Pellenc Sorting Technology. The result: homogenous low-density polyethylene film (LDPE), dry, uncontaminated, free from unshreddables, foreign objects and other affixed materials (chemicals, oils, organic components, material residues, sand, stones etc.).
Various buyers in the plastics processing industry use LDPE film to produce new products, for example shopping bags or rubbish collection bags. For ideal sorting results, the shredder discharge material, must be shredded to approximately the size of an A4 sheet. ‘A different output size would have a negative impact on sorting quality,’ says Timm Just, responsible for the ‘Plastics Purchasing’ unit at Veolia Umweltservice West GmbH.
The ideal combination of shredding and dosing
‘The Micromat BW is our latest model and was specifically developed as a bale opener for the dosed feeding of plastics such as film for automatic sorting systems,’ explains Stefan Scheiflinger-Ehrenwerth, Product Manager at Lindner. He emphasises that especially in plastics recycling, the shredder should not ‘only’ shred, but also perfectly dose the shredded material in order to optimally feed the subsequent automatic NIR sorting equipment. The Micromat BW therefore also acts as a dosing system.
And all this with consistently low energy consumption. The compact and stable single-shaft shredder can handle up to four tons per hour. Depending on the requirements and feed material, higher throughput rates are also possible. The Micromat 2000 BW shredder with a 132-kW motor and 105 rotations per minute is ideally tailored to the needs of recycling companies and waste recyclers with medium-sized waste streams.
