Navigating towards circularity overcoming barriers to the use of circular aggregates in the swedish construction sector

Abstract

Today the construction sector is a central contributor to global environmental challenges, accounting for a significant portion of resource consumption and greenhouse gas emissions. In Sweden, the urgency for sustainable practices in this industry has become increasingly apparent, particularly as the government pushes for a transition towards a circular economy. This report delves into the complexities of implementing circular material flows within the construction sector, emphasizing the reuse and recycling of aggregates as essential strategies to mitigate environmental impact while enhancing resource efficiency. The primary purpose of this study is to investigate how the Swedish construction industry, with focus on Swerock’s and similar companies' national operations, can strengthen the use of recycled materials and eco-products. By understanding the interplay of legislation, industry practices, and market demand, the study aims to identify practical barriers and opportunities for fostering a circular approach towards material use. Through a comprehensive literature review and an in-depth interview study involving key stakeholders within the construction sector, the research uncovers existing challenges, including insufficient regulatory support, financial barriers, and logistical issues that hinder the integration of reused materials into construction projects. Moreover, it highlights the critical need for collaboration among public authorities, private companies, and other actors to support circular practices. The findings reveal that while the Swedish Environmental Code provides a foundation for sustainable practices, gaps remain in its application that hinders innovative solutions for material reuse. Recommendations for enhancing legislation, encouraging circular practices, and fostering partnerships are provided to facilitate a successful transition into a more resource-efficient construction sector. This research contributes valuable insights not only for Swerock but also for a broader audience in the construction industry, offering a structured approach to promote sustainable material management within the framework of the circular economy
