accessories, including exhaust filters. The frame of the Hygiene AirClean filter on the new Boost CX1 vacuum cleaner is made from 100% recyclate. Sustainable packaging is another target area for Miele. It has, for example, converted its PowerDisk container for use with dishwash- ers to 100% recycled plastic. Computer accessories


group Logitech announced in


February that it had exceeded its commitment to incorporate post-consumer recycled (PCR) plastics into products. Its Creativity and Productivity

portfolio uses PCR at scale, with 65% of all mice and keyboard units now including PCR plastic, beating its commitment made in 2020 to use 50% PCR. Logitech estimates 8,000 tonnes of virgin plastic was eliminated in its products in 2021. “Now, all consumers have a breadth of choice when it comes to selecting mice and keyboards that are aligned with their sustainable lifestyle preferences,” says Delphine Donne-Crock, General Manager of Creativity and Productivity at Logitech. “By using post-consumer recycled plastic as our preferred material at scale, we have been able to take meaningful action to make sustainable living easy for consumers as well as make a substantial impact towards decreasing our carbon footprint.” The percentage of recycled plastic in each

Logitech product varies depending on the type, colour and material, ranging from 75% PCR content to 20% for technically complex and lighter colour products. It says that its development work with suppliers means there are now more than 30 colours in its product palette and its design goal is to maximize the percentage of recycled content in each product while ensuring high aesthetic appeal and durability tests are met.

materials supplied by Wipag, the recycling and compounding company owned by Otto Krahn Group. A component in industrial vacuum cleaners produced by Festool use Wipag’s WIC PA 66 compound which is reinforced with secondary carbon fibre. As the vacuum cleaners handle large amounts of dust and chips a pre-separator is integrated in the suction module to boost suction capacity. Wipag says that after a detailed analysis, its WIC PA 66 compound with a carbon fibre content of 30% was chosen as the material for this component. The secondary carbon fibre in the WIC com- pounds is sourced from lightweight component production waste and are reprocessed by Wipag

using a proprietary carbon recycling technology. The post-industrial fibre helps reduce the carbon footprint of applications and is a cost-effective alternative to virgin carbon fibre, says the company. The WIC compound used in the pre-separator of Festool vacuum cleaners is also electrically conduc- tive which prevents voltage breakdowns caused by the rotation of the dust. PA materials are common in electronic and automotive applications, but the source of waste raw material need not be those sectors. PA fibres can be recycled for use in technical applications and that is what DSM has done for smartphone applications for its customer Samsung. DSM’s Akulon RePurposed PA 6 is being used in Samsung Galaxy S22 smartphones and Tab S8 tablets. The waste stream for the material is fishing nets collected along India’s coastline which are repro- cessed into a material with minimum 80% recycled PA 6. The material is incorporated into key compo- nents including the Galaxy S22 series’ key bracket and inner cover of the S Pen, as well as Tab S8 series’ inner support bracket.

at Samsung Electronics, says: “Through this open collaboration, which combined our technology with DSM’s expertise, we successfully developed a solution that bridges the needs of the planet and our Galaxy users. The Galaxy S22 series and Tab S8 series help advance Samsung’s sustainability vision, Galaxy for the Planet, which includes reducing our environmental footprint by incorporating recycled
