Every component in power electronics experiences degradation over time, from semiconductors and capacitors to inductors and connectors. Thermal stress, material fatigue, and irreversible entropy processes determine how quickly parts age. Normalized KPIs and visualizations, such as radar plots, help engineers detect wear, plan maintenance, and make realistic lifetime predictions. 

As power electronics scales from microwatt IoT nodes to multi-megawatt energy infrastructure, its material footprint is growing just as rapidly. Circularity strategies are increasingly seen as a way to decouple performance gains from resource consumption and waste generation. This article reviews how far different R-strategies have already been adopted across key power electronics components and where practical limits remain.

With e-waste volumes increasing, a shift to a circular electronics economy is crucial for sustainability and economic growth. The refurbishing sector presents a lucrative opportunity, with potential to significantly reduce environmental impact while meeting escalating electronics demand. Embracing circular models offers businesses strategic advantages in efficiency and cost.

The circular economy in electronics focuses on minimizing waste and maximizing the use of materials. Using frameworks like the 10R hierarchy and 60R taxonomy, strategies promote extending product life and leveraging durable components such as semiconductors. The emphasis on “reuse at the highest level” supports longer use of entire devices, reducing new production needs. Future innovations like digital product passports and AI-driven maintenance are set to enhance sustainability in the sector.

In the face of rapidly increasing e-waste due to technological advancements, this article delves into global management strategies, focusing on WEEE, EPR, and PCF. It highlights the environmental impacts, emerging waste streams, and the necessity for cohesive policies to address the escalating e-waste challenge effectively.

E-waste is skyrocketing, with over 62 million metric tons produced in 2023, driven by digitalization and electric vehicles. Recycling faces challenges due to complex electronics. While urban mining offers a solution for precious metal recovery, effective management demands better design, innovative recycling, and comprehensive regulations.

The European Green Deal aims for EU climate neutrality by 2050, focusing on transforming the electronics sector through circular economy principles. It seeks to reduce electronic waste and encourages sustainable practices like reuse and recycling. This shift offers the industry a chance to enhance competitiveness and sustainability.
