From Trash to Treasure: Daly Plastics Transforms Dirty Agricultural and Packaging Film into High-Quality Regranulate
Daly Plastics is one of the largest plastics waste processing companies in the Netherlands. At the Zutphen site, the subsidiary Caroda Polymer Recovery recycles approximately 64,000 metric tons of used agricultural and packaging film. The aim is to produce polyethylene 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.
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. 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.
The second Jupiter 2200 primary shredder is installed in the hall shreds post-consumer film to A4 size. Optimum output and simultaneous dosing for subsequent sorting are essential for a smooth operation. ‘The A4 size is ideal for optical sorting processes,’ explains Peter Daalder. ‘It means the sensors can optimally distinguish LDPE from other PE and PP plastic types and separate it from the material stream.
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, whereby Linder WashTech’s Intensive Dry Cleaner 150/300 is used to remove leftover dirt and mineral build-up, as well as reduce the moisture present in the film.
The Micromat has proven itself a key component and benchmark for the target quality: the extrusion line is fed with the optimum particles. As Peter Daalder confirms and emphasises: ‘The machine fulfils two important functions in the line. It reduces the feed material to exactly the optimum particle size needed for the extruder and simultaneously doses the material. Another great advantage is the internal pusher to make feeding even more efficient. Thanks to the continuous, uniform output, the material can be cleaned effectively. The degree of purity determines the quality of the end product. The industry needs clean and homogeneous granulates to turn it back into film.’ Daly Plastics continuously checks the quality of the granulates in the laboratory and also produces rubbish bags for inspection.
