Dusseldorf (Germany), November 2022. Recycling specialist Lindner showed all-in-one solutions for efficient plastics recycling at K 2022 in Dusseldorf in Hall 9, booths B17/B19 and in the outside area CE02 as part of the VDMA Circular Economy Forum. In three daily demonstrations, different post-consumer rigid plastics were shredded live – and for the first time also wet washed. Working together with Engel there was yet another first: shredded rigid plastics were injection moulded and turned directly into new pallets on site.
As a pioneer in plastics recycling, Lindner knows what the recycling and circular economy wants: higher throughputs, short downtimes and maximum energy efficiency. The increased demand for quality recyclates also requires first-class washing components that can be added as modules depending on the degree of contamination. This can be achieved thanks to product innovations and the perfectly coordinated upstream processes of shredding – washing – sorting. As one of the few recycling specialists, Lindner offers all-in-one solutions to efficiently optimise these steps to process rigid plastics, films and PET.
Film recycling – optimised quality from the first process step
Whether post-commercial or post-consumer, films make up a lot of the world’s waste. Different degrees of contamination require adapted washing and drying processes. This is the only way to produce high-quality recyclates. The specific features of Lindner’s new Jupiter BW series ensure an increase in efficiency and quality. The new shredder setup is specially designed for film recycling. ‘Thanks to the Jupiter BW, we have succeeded in reducing the percentage of fines produced during shredding by 44% – as comparisons with other shredders have shown. The bad fraction to be disposed of by the recycler is thereby greatly reduced and more material is retained in the recycling stream,’ explains Stefan Scheiflinger-Ehrenwerth, Head of Product Management at Lindner Recyclingtech. ‘The precise cut shreds films to an optimal size of A4/A3 for downstream NIR systems. This makes the downstream sorting processes so much more productive and efficient.’
The new Micromat HP – the benchmark in plastics recycling
The novelty at K 2022: Lindner’s Micromat HP series. Micromat series shredders have been used successfully in plastics recycling for many years. The new series impresses with its powerful, gearless direct belt drive, the adjustable safety clutch that protects against non-shreddables and the unique adjustable knife system. The new model makes it possible to increase the throughput, leading to the improved productivity demanded by the market – the throughput for processing recyclable bales, for example, was raised from 3 t/h to 5 t/h. Another new feature is the automatic belt tensioning system, or ATB, which guarantees an optimal operating point, making the process more energy efficient and almost eliminating the need for maintenance – both welcome developments considering energy costs and the shortage of skilled labour that also affect the recycling industry.
