Things Are Hotting Up! Lindner Washtech Launches New Hot-Wash System for Effective Plastic Recovery

Recyclates that are barely distinguishable from virgin material – that’s what plastics processing specialist Lindner had in mind when developing the new hot-wash system to be presented at the K 2019 in Düsseldorf. In addition to effective cleaning, the solution offers not only high but above all continuous output.

Gone are the days when products made of recycled plastics were a well-intentioned but marginal phenomenon. Markets, and in particular big brands, have to react to the sustainability trend and are demanding ever-higher quality recyclates in ever-increasing quantities. To deliver this high quality, complex processing systems – and here, in particular, washing technology – are needed. One specific challenge is posed by undesirable materials stuck to post-commercial and post-consumer film as well as unpleasant odours. The more effectively these materials can be removed, the higher the quality and the potential revenue.

German-Austrian company Lindner Washtech has developed a three-stage hot-wash system to meet these requirements and also ensure high productivity. Managing Director of Lindner Washtech, Harald Hoffmann: ‘When developing the new components, we focused on effective cleaning and continuous processing so that all preceding and subsequent equipment can be operated productively at all times. That is why we based this solution on our tried-and-tested technology, combined it with the advantages of hot washing and deliberately left out the otherwise common, but often vulnerable, batch processing.’

Three stages to success

The modular and compact Lindner hot-wash system has three stages and does not require any additional conveyors. In the first stage, the shredded and pre-washed plastics are fed into a reactor, mixed with hot water and washed. Already at this stage, mixing arms apply concentrated friction to the material. The double discharge screw conveyor then feeds the plastics into the new hot-wash Rafter in optimally dosed quantities. This is a new and improved version of the already successful Rafter pre-washer, in which continuous friction is applied to the material to remove and separate residues effectively and gently. In the third and final stage, the Twister friction washer, a machine specifically designed for this application, removes the hot water or the hot caustic solution. The liquid is then separately treated.

Optionally the system can also be operated with caustic solution to remove even stubborn fat and oil residues, as well as glue. The downstream water treatment system continuously monitors the water’s alkaline content and automatically applies the necessary chemicals.

Alongside Lindner’s modern and robust shredders, the innovative hot-wash system is a key component in Lindner’s new system solutions for plastics recycling.

Lindner at the K 2019
In addition to the indoor booth in hall 9, D78/E75, Lindner Recyclingtech, together with its subsidiary Lindner Washtech, will be exhibiting for the first time this year in the outside area (15.2). A system solution consisting of a shredder and a dry-cleaning system can be seen live in action, recycling plastics twice a day.

K 2019: Lindner Focuses on System Solutions in Plastics Recycling

Three years have passed since the last K, the world’s premier fair for the plastics and rubber industry, and everything has changed. Apart from the media attacks on plastic products, the industry also has other challenges to overcome, such as China’s import ban on plastic waste and constantly increasing recycling quotas entering into force. Lindner, the Austrian waste processing specialist, has decided to tackle the technical aspect of this challenge head-on. At K 2019 the manufacturer of bespoke recycling equipment will be showcasing highly productive, turnkey system solutions for plastics processing that create perfect material for subsequent extrusion, as well as the next generation of the tried-and-tested Micromat shredder series and an exciting new hot-wash system.

Circular economy is the new buzzword and it has brought recycling companies out of their niche and into the limelight. Once current ad campaigns by major brands are also taken into account, it’s clear that this is a huge opportunity served on a silver platter. ‘Consumers around the world are demanding that resources – and particularly polymers – are used sustainably and responsibly. Many manufacturers are already responding to this trend by trying to provide as many products as possible with at least some recycled material,’ explains Harald Hoffmann, Managing Director at Lindner WashTech. ‘Current developments also place ever higher demands on recycled materials. As a result, more and more companies are requesting input materials of high quality and purity for their extruders. We focus on laying the groundwork for optimum subsequent processing with our signature shredding and washing technologies,’ says Hoffmann.

However, it is not only the quality that counts but first and foremost economically efficient processing itself. ‘Excessive expenditure has a direct impact on the costs of the end product. It is therefore important that processing systems operate at maximum productivity,’ states Stefan Scheiflinger-Ehrenwerth, Head of Product Management at Lindner. ‘We have harnessed our experience over recent years to develop innovations and further optimise our existing portfolio. Besides the next generation of our tried-and-tested Micromat shredder series and a completely overhauled cutting system, we concentrated our development efforts on finding the ideal combination of shredding, washing, sorting and drying components. Furthermore, by having implemented NIR sorting technology and the new hot-wash system, we now sport a product range brimming with well-engineered, high-quality components for optimum output. At K 2019, we will be showcasing turnkey system solutions that give our clients the confidence to face the latest challenges head-on,’ says Stefan Scheiflinger-Ehrenwerth.
