In 2020, Sweden´s construction industry generated approximately 14.2 million tons of construction and demolition waste, accounting for around 40 percent of the country´s total waste, excluding mining waste. Sweden aims to ensure that at least 70 percent of construction demolition waste should be prepared for reuse, recycling, or other recovery by 2025. However, the recycling rate in 2020 was 52 percent. Sweden's Circular Economy Action Plan highlights the potential to increase recycling in the construction sector. A majority of the renovation projects are the renovation of houses built between1965-1974. Houses built during this period are called the Million Program (Swedish:miljonprogrammet). These projects face a significant waste management challenge due to higher amount of waste, more materials, limited construction sites and housing, and absence of elevators. This thesis was conducted throughout interviews and a case study at Kvarteret Rackarberget, an innovation project in Uppsala, with NCC as the construction contractor. The purpose was to investigate material recycling in residential refurbishment in Sweden and identify challenges. The purpose was also to evaluate possible improvements to increase the proportion of construction waste that is recycled. The results indicate that increasing material recycling requires a higher rate of sorted waste, with significant potential for improving the sorting of plastic. To achieve a higher rate of sorted waste, the amount of combustible waste needs to be reduced by sorting materials to a waste container. Suggested improvements include better cooperation between construction and waste contractors, enhanced logistics at the construction site, and improved communication among all stakeholders. Achieving these improvements requires a strong willingness and commitment.
