A Case Study on Industrial Collaboration to Close Material Loops for a Domestic Boiler

This paper presents a practical implementation of circular principles in a case study on domestic boilers. The manufacturer and a recycling company collaborated by performing pilot studies on closing the aluminium cycle. The case study proved economically viable and not limited by technical or practical aspects. Additional benefits for both companies have been implemented and additional insights on the circular economy were observed. The results indicate that this form of sustainable manufacturing quickly transcends the boundaries of individual companies, which confirms the necessity of close collaboration with stakeholders in the value chain.
