Återbruk av byggnadsmaterial : En litteraturstudie om utmaningar som idag hindrar användningen av återbrukade byggnadsmaterial

Sammanfattning: Purpose: This study aims to identify obstacles and challenges that prevent the reuse of building materials and bring forth possible solutions. But also to examine the technical-, economic- and environmental advantages and disadvantages of using reused building materials. Method: The study is based on literatures that have been sustained from scientific articles, interviews and analyses of reference objects. The main study mainly consists of information gathered from scientific articles that have been analysed in a literature study. Information was also gathered from nine interviews that have been done with various professionals that works in the construction industry. Results: Several obstacles that arise when reusing building materials were identified. One of the major barriers is logistics and storage of recycled materials. Furthermore, legal and official requirements, the demolition process, guarantees, quality of the material and insufficient knowledge of those who work or want to work with recycling and material reuse. Based on the reference objects, the survey shows large environmental savings in both reduced carbon footprint and reduction of large amounts of demolition waste. Based on the literature analysis, proposals for solutions have been develop to all the obstacles and risks that have arisen. Conclusions: Finally, there are several obstacles that make it difficult to reuse in the amount that actors desire. Over time, recycling will increasingly become more common, and solutions will come along with it. But more research and more pilot projects will develop knowledge in recycling and facilitate development in general. New legislation promoting or forcing recycling projects will also be needed.
