Micromat Bale Opener Increases Film Quality at Veolia

At the Morschheim site in Germany, Veolia Umweltservice West GmbH operates a highly efficient sorting facility for post-consumer plastic films. Crucial to ensuring the best possible output quality in homogenous LDPE film is a Lindner-Recyclingtech Micromat 2000 BW shredder. This innovative machine also regulates the quantity of material and creates the perfect conditions for optical sorting by feeding the optical sorting system with the particles it needs.

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 here – innovative, powerful and highly productive while at the same time cost-efficient and therefore economical. 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, which is directly fed onto the sorting line, 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. Veolia Umweltservice West GmbH could not have made a better choice. 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.

In accordance with operational requirements, the robust shredder’s cutting system was equipped with 116 x 116 mm square cutters specially developed for this model series. The Micromat BW always produces an optimum particle output, which is essential for efficient optical sorting. Otherwise, parameters would have to be constantly adjusted. At Veolia Umweltservice West GmbH, the feed material is precisely and consistently shredded to approximately a DIN A4 particle size.

Since the very beginning Timm Just and his team have been completely satisfied with the Micromat 2000 BW: ‘The machine runs very reliably. The output film quality and therefore the LDPE film’s resale value have increased significantly.
