Silkeborg Affald & Genbrug Optimizes EPS Recycling

By using the right technical equipment, Silkeborg Affald & Gebrug was able to increase the recycling rate of used expanded polystyrene (EPS).

In the Danish town Silkeborg (located in the middle of the Jutlandic peninsula) approximately 30 tons – equivalent to more than 60 truckloads – of EPS are collected per year. Previously, the expanded polystyrene – better known under the brand name Styropor – has been a large part of the combustible fraction but is now compacted on site and sold for recycling with reduced transport costs. The compacted EPS blocks can now be loaded on just three trucks, and the optimization of the weight of the combustible fraction saves many trips to the incineration plant. Silkeborg Affald & Genbrug is using a compactor provided by Danish manufacturer Runi A/S. According to the information, it takes a few hours to compact the EPS, but this is a job that anyone can do. The compactor would work reliably – and provide the recycling of more plastic, which is an environmentally friendly result.

“During design, assembly and commissioning, Runi has been a professional supplier who has delivered agreed quality and function at the agreed price,” engineer Erich Beck at Silkeborg Affald & Genbrug, responsible for the purchase of the compactor model SK370, was quoted. “In addition to knowledge sharing with Danish colleagues, we have had the pleasure of visits from Finland, Norway and Israel during the five years of the plant.” Runi A/S is a Danish screw-compactor manufacturer, located in a region with a long tradition for eco-technology, machine manufacture and metalwork. Its machines are used to add value to a large number of different materials, either by making them suitable for recycling and onward sale or by reducing costs of transport, disposal or energy consumption.
