Sustainable Best Practices in Electronic Sector : Printed Circuit Board (PCB) Industry

Sammanfattning: Environmental issues related to the Electronic and Electrical Equipment industry lead companies to consider a new sustainability model to decouple economic growth from resource consumption and waste generation. A significant body of literature focuses on materials and process innovation in the field of Printed Circuit Board (PCB), simultaneously limited attention has been given to industry practices and circular economy strategies. This study aims to contribute insights into sustainable circular economy practices in the PCB industry; it examines the current integration of sustainability and circularity principles in PCB companies in Sweden and assesses the associated strengths, weaknesses, opportunities, and threats. Drawing on the strategies outlined in the Circular Electronic Roadmap, the study identified four main pathways relevant to design and development, procurement, and business model. The study, being exploratory and qualitative in nature, conducted semi-structured interviews with six PCB companies in Sweden. The results show that the concept of sustainability is dynamic, factors such as business nature, company size, market competitiveness, regulations, stakeholder’s expectations and priorities, and emerging frameworks are influencing the degree to which these practices are integrated into the companies. Numerous strengths include utilizing Life Cycle Analysis (LCA), adopting circular business model, sustainable technology innovation, and prioritizing environmental sustainability as an impact. Two main weaknesses are customers restriction and constrain in PCB design and upfront resource investment. Collaboration, local and regional innovation, active role of business association, and prospects for secondary market materials are discovered to serve as opportunities to advance the circular transition for companies Threats to sustainability practices include a lack of customer demand or interest, limited material information and traceability, and technical complexity of PCB. Overall, these findings could provide practical guidance for PCB companies and other stakeholders to support decision-making and actions to improve sustainability practices in the industry.
