Precise and powerful: new shredders on the market


Manufacturers are focusing on enhancing and advancing shredder technologies to improve the efficiency and effectiveness of plastics recycling as the contaminant levels and types of material for processing rise. These advances are taking the form of high-speed shredders that utilise powerful motors and robust cutting systems to achieve high through- put while reducing processing time, intelligent systems that improve the overall performance of the unit while trimming energy consumption, and size reduction control to achieve precise particle sizes with little waste. At the same time, several entry-level yet robust designs have been created to produce excellent quality recyclate at lower volumes. Lindner Recyclingtech says the demands placed on recyclate quality are increasing, specifi- cally higher throughput, shorter downtimes and maximum energy efficiency, even as more heavily

contaminated input materials are increasingly extracted from waste streams. “Packaging materials such as films, primarily made of polyethylene and polypropylene, have a particularly short product life cycle and also account for a significant portion of waste generation worldwide,” says the company. The company introduced at last year’s K show its


new Jupiter BW series of shredders, designed in a setup specifically tailored for precise, true-to-parti- cle shredding of post-consumer film fractions. The new model, which extends the Jupiter series, can consistently shred the input film material to a 150-250 mm particle size, which allows a down- stream NIR sorting system to then sort the material optimally.


Another benefit of the precise shred cut is a 44%


reduction in the proportion of fines generated by shredding that are unusable for the recycler, and
