dc.description.abstractIn response to the pressing climate crisis challenges facing society, there is a critical need for industries to transition towards a circular economy, encompassing entire production chains. Ateljé Lyktan, a company specializing in innovative lighting solutions, aims to reduce its environmental impact through the selecting of sustainable materials. This thesis investigates potential sustainable materials for indoor lighting products through a comprehensive situation and life cycle analysis of an existing product in ateljé Lyktans’s range, coupled with extensive literature research to identify current market alternatives. The study identified several material options, focusing primarily on biologically based polymers and polymer composites. These alternatives were evaluated using a two-step methodology. The initial screening employed both the chart method and a questionnaire method, while the following ranking process utilized a decision matrix to pinpoint the most promising materials according to this study. The findings highlighted two promising candidates: polylactic acid (PLA) and the composite Biodolomer I. However, neither material fully satisfied all requirements, particularly in terms of durability necessary for the long lifecycle of indoor lighting products. Further investigation into fiber reinforcements, which can enhance the mechanical properties and longevity of bioplastics, revealed flax and hemp as suitable options. Additionally, the fibers OnceMore and FibraQ were recommended for further testing. The study underscores the necessity for developing sufficient end-of-life infrastructure, including new technologies for recycling and composting, to facilitate the large-scale adoption of bioplastics and fiber-reinforced materials. The conclusion calls for ongoing research into sustainable material alternatives and emphasizes the imperative for industries to intensify efforts towards sustainability. This includes the development of robust infrastructure for material recycling and composting, essential for achieving a circular economy
