Naturally, a styropor box made from chemically recycled plastic needs to prove itself, particularly as compared to conventional boxes. Here, Ccyled wins over clients thanks to its great thermal insulation, and in addition to this, the boxes are resistant to compression, bending and can be stacked stably. The recycled styropor thus has the same properties as the conventional alternatives. The ecological balance sheet also looks good: the recycled airpop version reduces CO2 by at least 50 percent. "Chemical recycling of plastic waste is not only an important component of the European circular economy, it is also particularly useful for applications which have stringent requirements in terms of quality and safety, for example food packaging and protective packaging or pharmaceutical boxes. Therefore, we are very proud of the ChemCycling project and to manufacture EPS fish boxes for Bremnes Seashore. We are delighted that we can thus help our customers to achieve their sustainability goals," explains Klaus Ries, Head of Global Business Management for Styrenic Foams at BASF.
A further benefit: Vartdal Plast benefits from the fact that the material can be processed like new material, meaning that the production processes do not need to change. At BASF, recycled and fossil raw materials are mixed in the production Verbund and the proportion of recycled matter is calculated and allocated via a mass balance. Both the process of allocation and the product are certified by an independent testing authority.
Styropor has been a well-known material for 70 years, and is particularly popular in passive cooling systems. Therefore, the boxes are gaining ground both in the pharmaceutical industry and the food industry. The world's first EPS fish boxes are in use in Norway thanks to Ccyled. The standard box from Vartdal Plast, which weighs just 600 grams, can hold around 22 kilograms of fish.
For Vartdal Plast, the new boxes are particularly amazing because they are recyclable. In Scandinavia and other European countries, the boxes are collected, compressed, crushed and recycled. The company operates two high-capacity compacting plants for EPS waste in Norway. In the long term, Vartdal Plast is looking to feed the compacted material back into their Vartdal Loop product series and thus manufacture boxes that are made entirely from recycled styropor.
