For much of the history of electronics, repair was simply part of ownership. Radios, televisions, and early consumer electronics were built with the expectation that they would be maintained over time. Service manuals were widely available, spare parts could be ordered, and local technicians routinely repaired equipment that might remain in use for decades. When something stopped working, the natural response was to find the faulty component and replace it.
The need for repairability was largely practical. Electronics were expensive, and repairing them was usually more economical than replacing them. Equipment stayed in service longer, and fewer products were discarded. Today, this would be recognized as a sustainable approach to product design.
Over time, the industry has changed. Advances in semiconductor integration, manufacturing scale, and global supply chains have made electronic products smaller, more capable, and far more affordable. In many cases, it has become easier to replace a device than to repair it.
At the same time, the concept of sustainability has taken a different direction. Now that electronic devices are more widespread and energy consumption has increased, the focus has shifted to efficiency. Engineers strive to reduce power consumption, increase battery life, and improve the performance of power supplies and electronic systems. These developments have delivered measurable benefits.
However, energy efficiency is only part of the story. The environmental impact of a product begins long before it is switched on. Raw materials must be sourced and moved through global manufacturing and supply networks before they ever become part of a finished device. Eventually, every product reaches the end of its life, raising questions about whether its components can be recovered or whether it will simply become electronic waste.
This perspective is reflected in the Ecodesign for Sustainable Products Regulation (ESPR).[1] Although ESPR is a European Union (EU) regulation, its influence extends globally. Modern electronics are designed and manufactured through global supply chains, and products intended for international markets often need to satisfy multiple regulatory frameworks. As a result, the design principles encouraged by ESPR can shape engineering decisions worldwide.
None of these ideas is completely new. Engineers have always designed systems with reliability and service life in mind, while also paying close attention to the materials used in a product. What is changing is the emphasis placed on these principles and the way they are connected to environmental responsibility.
A Broader View of Sustainable Design
The ESPR reflects a growing recognition that sustainability cannot be defined by a single metric. In earlier discussions, energy consumption was often treated as the primary measure of environmental performance.
However, sustainability is rarely linear. A design that reduces energy consumption might rely on materials that are difficult to recycle, while a product intended for extreme durability may require additional resources during manufacturing.
For engineers, the challenge is to consider these factors together rather than in isolation. ESPR supports this broader perspective by highlighting several aspects of product design that influence environmental impact. Durability becomes important because products that last longer reduce the need for replacement, while repairability allows systems to remain in service when individual components fail. Responsible material selection helps limit the presence of substances that may pose risks during manufacturing or disposal.
ESPR places these familiar design decisions within a framework that emphasizes life cycle responsibility.
Designing Products That Last
Extending product lifespan is one of the most effective ways to reduce environmental impact. Manufacturing electronic equipment requires substantial energy and raw materials. When devices are replaced often, those same resources are used again to produce replacement hardware. When engineers design products that remain in service longer, it reduces the need to build new equipment. Product lifespan depends on everyday design decisions, from the components design engineers select to how heat is managed and how well the mechanical structure holds up over time.
Reliability testing plays a critical role as well. Accelerated life testing and environmental qualification allow engineers to identify potential failure mechanisms before products are deployed in the field. By understanding how components behave under stress, designers can develop systems that continue to function reliably over extended periods.
Connectors and other electromechanical components often warrant careful consideration in this context because they undergo repeated mechanical cycles and may be exposed to harsh environments. Selecting components designed for the appropriate duty cycle can significantly extend the product’s overall lifespan. Longevity remains one of the most effective sustainability strategies available to engineers.
Designing with Maintenance in Mind
Repairability is receiving renewed attention. Many types of equipment, including industrial systems, telecommunications infrastructure, and transportation equipment, are routinely designed to be serviced throughout their operational life.
Consumer electronics have sometimes followed a different path. The same integration that makes modern electronics smaller and more capable also makes them harder to repair. Products assembled with adhesives, sealed enclosures, or tightly integrated modules are extremely challenging to service (Figure 1).

Designing with maintenance in mind does not always require radical changes. In many cases, it involves avoiding choices that unnecessarily prevent repair. Modular construction can allow assemblies to be replaced independently. Fasteners that can be removed without specialized tools make it easier to access internal components. Parts that experience predictable wear, such as batteries or connectors, can be designed for straightforward replacement.
Clear service documentation and spare parts availability also support repairability. These practices help ensure that products remain useful even when individual parts fail. Repairable design embraces the idea that products should not be treated as disposable when they can reasonably be maintained.
Considering End of Life
Eventually, every product reaches the end of its useful life, and global electronic waste (e-waste) continues to grow, estimated to reach 82 million metric tons by 2030.[2] The ability to recover valuable materials has become more important. Electronic assemblies (Figure 2) contain valuable materials, such as copper and aluminum, and recovering these resources reduces the need for additional mining and refining.

However, effective recycling depends on how products are designed. Assemblies that combine many different materials or rely on complex bonding techniques can be difficult to separate into recyclable streams. When components cannot be easily disassembled, useful materials remain trapped in mixed waste. Material recovery improves when products use fewer material combinations and avoid coatings that interfere with recycling. Assemblies that can be taken apart at the end of their life also make it easier to separate materials into useful recycling streams.
Recovery and reuse are key to a circular economy, which encourages materials to remain in productive use for as long as possible rather than being discarded after a single life cycle.
Materials and Substances of Concern
Sustainability also requires attention to the substances used within electronic products. Regulations such as the Restriction of Hazardous Substances (RoHS) directive and the Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) regulations have already established limits on materials that may pose risks to human health or the environment.
ESPR focuses on the materials throughout the electronic design process. Engineers often rely on supplier documentation and material declarations to confirm that components meet regulatory requirements.
Compliance gets complicated because modern electronic systems rely on complex global supply chains. One product may contain components sourced from dozens of suppliers, each with its own materials and manufacturing processes. Ensuring compliance often comes down to careful documentation and close coordination between manufacturers and their suppliers.
Checking material compliance early in the design process helps avoid costly redesigns later in development. When environmental requirements are considered alongside performance targets and reliability goals, sustainability can become a normal part of the product development workflow.
Tools That Support Sustainable Design
While sustainability introduces additional considerations, engineers have access to a growing set of tools to understand how design decisions affect environmental impact.
Life cycle assessment (LCA) software estimates the environmental impact across the different stages of a product’s life cycle, including material extraction, manufacturing, transportation, use, and disposal.[3] These models allow design teams to compare alternatives; for example, an LCA model may help a designer determine whether a heavier but longer-lasting enclosure reduces overall environmental impact compared to a lighter design that has to be replaced more often.
Many LCA tools are now part of product life cycle management (PLM) and computer-aided design (CAD) environments. This allows engineers to evaluate material choices and manufacturing methods while designs are still evolving. Selecting a different alloy or switching to a recyclable polymer can be evaluated not only for cost and performance, but also for life cycle impact.
Simulation and digital twin technologies are also playing a role. Thermal and reliability simulations allow engineers to estimate a product’s expected lifetime. A design that runs cooler or avoids mechanical stress may last significantly longer, reducing the need for replacement hardware.
By considering these principles early in the development process, engineers can incorporate sustainability into the typical design trade-offs.
Conclusion
ESPR expands how sustainability is considered throughout product design. Instead of focusing on energy consumption during operation, it focuses more on the materials used in a product, how long the equipment can stay in service, and what happens when the product reaches the end of its life.
Engineers are already familiar with these considerations. Reliability, maintainability, and responsible material selection have always influenced the design of electronic systems. ESPR places these decisions within a regulatory framework that connects them directly to environmental impact.
Sustainable design often aligns with good engineering practices. Products that feature long life cycles, can be serviced, and allow materials to be recovered at the end of use reduce waste and resource consumption. ESPR underscores the importance of these decisions in an engineer’s everyday work.
