Making More Plastics Recyclable

To date, it is nothing but the wishful thinking of many plastics recyclers: that recyclability is taken into account right from the very beginning of a product's life cycle, at the product design stage. A new project aims at making this dream come true. Whether multi-layered food packaging, power cable sheathing or a toothbrush: Many plastic products cannot be recycled. This is the case, for example, when products are made of multiple materials that cannot be separated at all or only insufficiently. Only 16 percent of plastic waste produced in Germany is also recycled here. This figure is quoted by the Plastikatlas 2019 published by the German Federation for the Environment and Nature Conservation (BUND) and the Heinrich Böll Foundation. The majority of plastic waste is thus burnt in waste incineration plants to generate energy or is used as alternative fuel. Design and recycling - worlds apart . Making more plastics recyclable: The Chair of Business Administration and Business Information Systems at Julius-Maximilians-Universität (JMU) Würzburg in Bavaria, Germany, has been working towards this goal since July 2019 together with the German Plastics Centre SKZ and two partners from the Bavarian plastics industry. The partners aim at increasing the share of recyclable plastics by reducing the number of material components. "We focus on the product design stage because the recyclability aspect has largely been neglected by designers so far," says Jan Werner from the SKZ, a member of the Zuse society of independent research institutes. "Designers and recyclers live in two completely different worlds; there is no exchange of information." This is why designers often choose materials that are very difficult to recycle.
