The electronic industry faces increasing pressure to enhance product sustainability across the supply chain. Understanding the environmental impact of electronic devices is vital for informed decision-making and meeting customer demands for eco-friendly products among growing environmental concerns and regulatory pressures. This paper evaluates the sustainability impact of a Swedish electronic component manufacturer, TSS AB, specializing in temperature-sensing solutions, considering both the company’s and their client’s perspectives. Employing a life cycle assessment (LCA) and LCA software tools, we comprehensively analyze environmental impacts. Through a cradle-to-grave assessment, we evaluate production processes, reverse logistics, refurbishment, reuse, and disposal, identifying environmental hotspots for improvement. Additionally, we explore the influence of regulatory frameworks on incentivizing sustainable product development. Our findings contribute to the electronics sector’s growing emphasis on sustainability, offering insights for companies aiming for net-zero emissions and circular product lifecycles.
