How does the process work.
- Cable waste is sorted and removed from metals.
- The recycled plastic material from the cable waste is transported to Axjo for further processing.
- The material is ground and dried.
- In the mixing process, a polymer matrix composite – a filler used to adapt the volume of the product –, is added, along with a colouring agent, UV protection agent, etc.
- In the compounding process, the materials are ground together and any contaminants, moisture or residue in the recycled material are removed.
- The result is a finished granulate ready for injection-moulding of new drums.
Taking plastic recycling to a new level.
The Greenology Concept is made up of many different parts. One of the most important is helping our customers reduce their carbon footprint. A key initiative has been to work with leading manufacturers and research institutes to develop a method for utilising waste from power cable production using XLPE. XLPE is PE (polyethylene) which is cross-linked with an additive to improve its properties. This results in scrap that is very difficult to use in a recycling stream. Together with NKT, Borealis, and Swerea IVF, Axjo has managed to succeed throughout the entire value chain. Effective recycling at NKT’s recycling plant, together with use of a sophisticated method in Axjo’s mixing and compounding process in Gislaved, have proved successful. Products are now being developed with a significant PEX content as an impact modifier. These innovative products have been on the market for over a year, and both cable manufacturers and end-users have been very satisfied with the outcome. The reuse of 1,000 kg of XLPE provides a saving of 2,000 kg of CO², helping our customers become more sustainable and more profitable as the waste does not need to be sent to landfill or incinerated.
