The aim of the project was to map PVC waste streams in Denmark, Sweden, Norway and Finland. The available estimates are made occasionally, mostly within the frames of different projects and are not based on any formalized official reporting system or other rigorous accounting scheme. Overall, a large part of PVC waste ends up in mixed waste fractions and is eventually treated in waste-to-energy plants. Landfilling of PVC waste is banned in two countries, but some exceptions exist. Norway is the only country that treats some PVC waste as hazardous waste. The current waste treatment situation in the four Nordic countries is driven by several factors, such as diverse origins of PVC products, some specifics of the Nordic market, rather low focus on PVC waste in policy strategies or plans, technical issues regarding incineration of PVC waste, and the lack of domestic recycling.

Environmentally sound disposal of Ozone Depleting Substances is increasingly recognised as an important issue in terms of both the protection of the ozone layer and the effect on climate change. However, there is only a limited overview in the Nordic countries of product groups containing Ozone Depleting Substances, regulation of the substances, available treatment technologies, and waste infrastructure etc. This report provides an overview of the waste treatment and regulation of Ozone Depleting Substances in the Nordic countries. The report identifies gaps, proposes solutions and provides recommendations for relevant Nordic efforts within the area.

Achieving a high quality of waste plastic materials and recycling processes is a key challenge in closing the resource loops for plastics. This report reviews the status and trends for plastic waste flows and treatment in Denmark, Finland, Norway and Sweden. Furthermore, it gives an overview of existing policy instruments and the main challenges for designing policy instruments for improved recycling of plastic waste in these Nordic countries. The report identifies potential market failures associated with closing the resource loops for plastics. It reviews the economics research literature on policy instrument design for achieving optimal recycling rates and makes policy recommendations from the Nordic perspective. Finally, it presents results from a survey on market conditions to managers in the recycling and plastic manufacturing industry in Sweden.

This book highlights the design, use and structure of blockchain systems and decentralized ledger technologies (B/DLT) for use in the construction industry. Construction remains a fragmented change-resistant industry with chronic problems of underproductivity and a very low digitization factor compared to other fields. In parallel, the convergence, embedding and coordination of digital technologies in the physical world provides a unique opportunity for the construction industry to leap ahead and adopt fourth industrial revolution technologies. Within this context, B/DLT are an excellent fit for the digitization of the construction industry. B/DLT are effective in this as they organize and align digital and physical supply chains, produce stigmergic coordination out of decentralization, enable the governance of complex projects for multiple stakeholders, while enabling the creation of a new class of business models and legal instruments for construction.

This is the third Environmental Performance Review of Denmark. It evaluates progress towards sustainable development and green growth, with special features on waste, materials management and the circular economy and chemicals management.

Biodegradability of Conventional Plastics: Opportunities, Challenges, and Misconceptions brings together innovative research on the biodegradability of conventional plastics, providing an extensive overview of approaches and strategies that may be implemented, while also highlighting other methods for alleviating the eventual environmental impact of plastics. The book begins by providing a lifecycle assessment of plastics, the environmental impact of plastic waste, and the factors that affect the biodegradability of plastics. The different categories and terminologies surrounding bio-based plastics and biodegradable plastics are then defined and explained in detail, as are the issues surrounding bioplastics. Other sections discuss biodegradability, approaches for enhanced biodegradability of various major types of plastics, including polyolefins, polyethylene terephthalate (PET), polystyrene, poly(vinyl chloride), automotive plastics and composites, and agricultural plastic waste. The final part of the book focuses on further techniques and emerging areas, including the utilization of chemical additives, nanomaterials, the role of microbes in terms of microbial degradation and microbial attaching, revalorization of plastic waste through industrial biotechnology, and future opportunities and challenges. - Explains the fundamentals of plastic waste, lifecycle assessment and factors that influence the biodegradability of plastics - Provides novel techniques for improved biodegradability, exploring areas such as pre-treatment, chemical additives, nanomaterials and microbial degradation - Addresses current challenges and limitations in relation to bio-based and biodegradable plastics, microplastics and nanoplastics from bioplastics and plastic waste

Available online: https://pub.norden.org/temanord2023-544/ This publication addresses the challenges in managing Construction and Demolition Waste (CDW) in the Nordic countries including an outlook on other European countries. Despite a 70% recovery target, the Nordics lag behind due to economic, legislative, and social barriers. The study emphasizes the need for better CDW statistics and highlights successful European initiatives. Key findings include that the barriers do not seem to be technical feasibility, but rather include economic obstacles, and regional variations in recycling. Recommendations include unified approaches, regulations, and stronger incentives for reuse and recycling of CDW. The study advocates waste prevention through reuse and design strategies for future constructions, emphasizing collaboration within the Nordics and the EU.
