Circularity
Introduction
Sustainability requires a holistic and integrated approach that considers the complexities or convolutions of the full supply chain and encourages a shift away from short-term, reactionary practices toward long-term thinking and responsible decision-making. Achieving sustainability often involves making informed and sometimes difficult choices that balance the needs of the present with the current and future impacts over the full lifecycle of electronic products.
Circularity, in the context of sustainability and resource management, refers to an economic and production model that aims to minimize waste, optimize the use of resources, and promote the continual reuse, recycling, and regeneration of materials and products. This concept is in contrast to the traditional linear economy, which follows a "take-make-dispose" pattern, leading to significant resource depletion, environmental degradation, and waste generation.
Circularity involves several key principles (see Figure 1):
Design for Longevity—Products are designed to have an optimally extended lifespan, using durable materials and construction techniques to ensure the electronic system can be used for as long as possible.
Reuse and Repair—Emphasis is placed on repairing and refurbishing products instead of discarding them. This prolongs their useful life and reduces the need for new production.
Remanufacturing—Products are designed and manufactured in a way that allows their components to be easily disassembled and reused in new products, reducing the demand for virgin resources.
Recycling—Materials are recovered from products at the end of their life cycle and processed to create new materials, reducing the need for raw materials extraction.
Resource Efficiency—Processes are optimized to minimize waste and energy consumption throughout the entire product life cycle.
Sharing Economy—Resources are shared among multiple users, reducing overall demand and optimizing utilization. Examples include cloud services, ride-sharing services and co-working spaces.
Bio-based Materials—Renewable and biodegradable materials are used to replace non-renewable and environmentally harmful materials.
Intelligent Digital Solutions—Technologies such as blockchain and artificial intelligence/machine learning (AI/ML) are used to track and optimize resource flows, improve supply chain transparency, and enable efficient recycling and reuse.

The shift towards a circular economy requires collaboration among governments, businesses, consumers, and other stakeholders. It involves rethinking product design, business models, and consumption patterns to create a more sustainable and resilient economic system that aligns with the principles of environmental conservation and long-term well-being. In the following tables for Needs, Gaps and Challenges, as well as Potential Solutions, social and economic considerations can factor more strongly than technology.
Circularity in the Electronics Industry
Circularity presents many areas of opportunity for the electronics industry, as follows:
Innovation and Design—Sustainable design practices are gaining momentum, focusing on modular and upgradable products, as well as using eco-friendly materials that are easier to recycle.
Electronics as a Service—Cloud and other asset-management solutions will continue to grow in the business-to-business (B2B) sector. We can already see elements of this in the business-to-consumer (B2C) large-volume goods like smart phones, where carriers are setting up mechanisms for device renewal and reuse through financial incentives such as generous trade-on allowances.
Circular Economy Initiatives—Initiatives like the “right-to-repair movement”, take-back programs, refurbishment, and remanufacturing are gaining traction around the globe.
End-of-Life—Customers of the electronics industry generate a significant amount of electronic waste (e-waste) due to rapid technological advancements and short product lifecycles. Efforts have been made to improve e-waste management through recycling programs, proper disposal, and regulations. However, e-waste remains a concern, especially in developing countries where informal recycling practices have led to environmental and health hazards.2

Circularity Critical Materials: 4Rs
The iNEMI roadmap team developed a comprehensive table of materials with considerations to use in electronics, potential recovery value, availability, circularity pathway with respect to the 4Rs, solutions to achieving such a pathway, and a timeline of readiness level. It is available as an interactive spreadsheet for general use as well as compounds for printed circuit board applications.

Conclusions
Circularity is a key part of sustainable electronics. By closing the material loop, resource utilization can be maximized while waste produced over life cycle can be minimized. Promoting circularity within the electronics industry is closely related to material selection and supply chain management. There are also unique challenges due to the involvement of many stakeholders. The roadmapping efforts have identified the following issues:
Leadership for change—Industry should take the lead on the circularity transition. We expect some companies will act as the leading change agents to demonstrate a new value proposition with financial success and thus help followers to navigate the new space. As a more environmentally conscious generation becomes corporate leaders, this trend will accelerate.
Business model—Circularity requires significant changes to the manufacturing business model, likely from product-oriented to service-oriented, e.g., towards electronics-as-a-service. Developing a tiered market could also extend product use life. New business models may be needed to extend the current collection and recycling networks. Financial incentives from governments and sources will help the development and adoption of the new business models.
Metrics and methodology—Although there are many metrics and methodologies that have been developed for circularity, one suitable for electronics remains to be established and standardized. Industry consensus is very important to maintain a level playing field.
Technologies to support cost-effective reuse, remanufacturing, and recycling—Business-to-business reuse, remanufacturing, and recycling have made significant progress while consumer electronics face challenges and the efforts need to be scaled up. New technologies and approaches are needed to overcome the hardware and software limitations for reuse and remanufacturing and to find pathways for currently unusable and unrecyclable components. It is also critical to make sure recovered components and materials find entry into production, while still assuring reliability. There is also increasing pressure on resolving critical and strategic materials challenges. It is expected that the standardization and adoption of digital product passport technologies and practices could facilitate the development of these technologies.
Education—Workforce development and training of engineers in practice are needed to promote circularity. Efforts should be put into the development of new modules, courses, certificates, and programs. In addition, outreach to the public is also important to change consumer mindset.
Product design for circularity—The current design paradigm takes does not take circularity into consideration. This approach makes finding cost-effective reuse, remanufacturing, and recycling pathways extremely difficult. A proactive design approach with circularity in mind and the development of supporting tool capabilities can greatly optimize effective end-of-life management efforts, while not compromising on product performance and reliability.
