Daly Plastics: With Lindner to high-quality regranulate
Contaminated agricultural and packaging film are lead back into the cycle
Daly Plastics is one of the largest plastics waste processing companies in the Netherlands. At the Zutphen site, the subsidiary Caroda Polymer Recovery recycles agricultural and packaging films. The aim is to produce regranulates of the same quality as virgin material. That requires innovative solutions. Two Jupiter 2200 and four Micromat 2000 shredders from Lindner Recyclingtech provide the recovery facility with the ideal particle size.
The agricultural film is collected from over 2,500 farmers in the Benelux countries and northern Germany. Approximately 64,000 metric tons of used film arrive for processing each year, the majority of which is recycled as reusable polyethylene recyclate (regranulate).
Lindner Jupiter – the perfect primary shredder for agricultural and packaging film
Daly Plastics relies on Lindner’s technological expertise for film shredding. Two Jupiter 2200 and four Micromat 2000 shredders are in continuous operation – four shifts, 24/7, 365 days a year. The material delivered to the site is weighed, roughly pre-sorted by crane grabbers and fed onto a conveyor belt for processing. A Jupiter located just outside the sorting hall shreds the agricultural film so that the drum screen can do a better job of filtering stones and soil out of the material. ‘Agricultural film often contains foreign material such as lumps of soil or stones. Even large foreign matter in the feed material doesn’t make any difference to Jupiter,’ says Peter Daalder, adding: ‘That’s one of the main reasons why we decided to buy Lindner shredders.’
The second Jupiter 2200 primary shredder is installed in the hall, in front of one of Pellenc’s most advanced automatic NIR sorting systems, and shreds post-consumer film to A4 size. Optimum output and simultaneous dosing for subsequent sorting are essential for a smooth operation. In addition to these features, the Jupiter also pushes all the right buttons with its low energy consumption (energy-efficient drive, flywheel energy storage), resistance to foreign parts, as well as easy operation and maintenance.
Four Micromat shredders ensure the perfect output and dosing
The recycling of the film flakes next door comprises fine shredding, dry cleaning, extrusion and granulate bagging. Each of the four lines processes one colour of film and is equipped with a Lindner Micromat 2000. An economical solution for Daly Plastics/Caroda: with a capacity of two to three metric tons per hour, the Micromat produces 50-millimetre particles. This is ideal for subsequent dry cleaning. Subsequently the clean film flakes are granulated and transported to the extruder. The very homogeneous grey, black and brown granulate pellets are used to produce new tear-resistant film and, for example, waste collection bags.
Peter Daalder is very satisfied with the overall system and would choose Lindner’s innovative machines again in future.
