The construction sector is the largest producer of waste in the European Union (EU) and each EU member state needs to take the necessary steps to reduce the quantity of construction waste. Similarly, Sweden's construction and demolition (C&D) sector generates the majority of the country's waste. Consequently, Sweden is now striving to make its construction operations more sustainable. With an emphasis on the function of a Swedish property owner, this study attempts to explore ways of managing materials and waste from interior office remodeling projects in a sustainable manner andinvestigate challenges and opportunities while getting insights and viewpoints from different parts of the value chain. The study additionally explores what measures the property company can apply to enhance their sustainable efforts.To accomplish this, coding and thematic analysis were conducted on data obtained from semi-structured interviews with relevant stakeholders, articlesfrom peer-reviewed journals and grey literature, alongside observations gathered from site visits. The analysis resulted in nine themes that highlightthe challenges and opportunities within sustainably managing material and waste from remodeling projects. The identified themes were (1) Regulations and strategies, (2) Economic aspects, (3) Stakeholder impact, (4) Collaboration, (5) Routines, (6) Material and waste management, (7) Reuse market, (8) Quality of product and (9) Digital systems. The study discusses the findings and initiatives that support sustainable operations in interior office renovation projects and concludes with suggestions for future work and recommendations for the property company.
