A closed loop system for composite construction panels has been developed and trialled by four companies in south Wales. Panels made by Eurobond, which were processed during the trial by Sims at its facility at Newport, can now be 100% recycled. Sims and Eurobond developed the system in partnership with Corus and Rockwool, which manufacture the metal sheets and wool insulation that make up the panels. Large panels are broken down during the process so that the steel sheets can be separated from the mineral wool contained inside.Recovered materials are delivered back to Corus and Rockwool and both companies have set-up operations to reuse them in their manufacturing processes. Eurobond managing director Simon Thomas said: Eurobond is committed to reducing the environmental impact of its products from cradle to grave. To achieve this we must involve all parts of the supply chain and this project is a prime example of this approach. Eurobond has worked closely with Corus, Rockwool and Sims so that we can offer our customers a true recycling route for our product. Sims Newport facility general manager Paul Wake added: The processing of the panels today demonstrates that Sims has the technology and machinery in place to recycle mineral wool cored composite panels and separate the mineral wool and steel.
