Industry growth has consequences.
Rapid growth for semiconductor companies has meant increasing amounts of spent materials and chemicals. As expected, these have enlarged environmental impacts, disposal costs, and liability. Semiconductor companies confront challenges that not every sector faces: larger company size, higher value added per unit of production, and higher technological capacity are not always related to lower quantities of waste per unit of production.
Collective action is needed to turn this challenge into business resilience. SEMI, imec, and our SEMI Circularity Working Group community are sharpening our cooperation to meet the need.
MOVING FROM LINEAR TO CIRCULAR
Semiconductor value chain companies are making strides to pivot from a linear economy (take, make, waste) to a circular economy (maintain, reuse, refurbish, remanufacture, recycle). Early strategies were anchored primarily to waste management, waste-to-energy, waste diversion, and recycling programs. Lately companies are expanding to novel raw materials strategies, waste repurposing methods, and improvement of remanufacturing through resale at new-product-like performance and quality.
This is a real opportunity for companies because using spent chemicals as a feedstock can cut costs, bolster supply chain management, reduce greenhouse gas emissions, create opportunities for brands, and bolster social license to operate.
Yet most breakthroughs in circular practices are happening in relative isolation across the value chain. Until now, there is no widely recognized system for identifying and ranking materials used in manufacturing to prioritize where conversion from linear to circular use would provide the most gains.
A FRAMEWORK FOR PRIORITIZATION
A 2025 report – produced through collaboration between SEMI and imec – presents an inventory of 69 distinct materials prioritized for circularity along with the framework for ranking. It also shares the method to support calibration to fit specific use cases. The outputs will be immediately useful for decision-makers across functions in the semiconductor value chain, including, but not limited to:
- Procurement
- Sustainability
- EHS (environment, health, and safety), and
- Risk management.
These professionals now have a cross-industry reference for driving impactful circular initiatives at their firms.
CATALYZING RESEARCH DEVELOPMENT, VALIDATION, AND ADOPTION
In conjunction with the publication, SEMI and imec are launching the Circular Semiconductors Research Network, a platform to connect research teams with industry adopters to accelerate validation and deployment of circular technologies and methods. Ideal collaborators can substantiate Technology Readiness Level (TRL) 4 or greater and seek industry validation, adoption, and acceleration of circularity solution deployment aimed to purify, reuse, and/or resell spent materials and by-products – either onsite or offsite at a permitted facility under the conditions set out in our invitation.
Research teams with relevant subject matter expertise are welcome to submit proposals for research in exploratory phases (lower TRLs) for review by SEMI members. Preference will be given to research teams that address practical hurdles faced by semiconductor value chain companies as they navigate regulatory frameworks for onsite vs. offsite treatments.
The call for collaboration seeks to amplify research and development of technologies that comply with applicable regulations and meet one of the following conditions: (1) the owner/operator does not need to obtain a waste permit, or (2) the technology needs to be put offsite at a permitted waste facility.

THE BIGGER PICTURE
The publication and launch of the Circular Semiconductors Research Network is a response to growing attention from business leaders and policymakers on critical materials in semiconductor manufacturing. Supply chain security for these materials has become a strategic issue for governments and the private sector, not only because it could affect the pace of the energy transition but also because materials sourcing has become contested among geopolitical rivalries and alliances.
The network will provide momentum for industry and research to prioritize the development and adoption of circular methods for materials that would generate the most strategic, economic, and environmental gain in the semiconductor value chain. It will do so in dialogue with the SEMI Circularity Working Group, a venue for collective action among SEMI members that works closely with other trade association initiatives such as the SEMI Supply Chain Management Initiative, which is focused on resilience, agility, and responsibility, and the SEMI Accelerating Sustainability with Smart Manufacturing Task Force, which develops an industry technology roadmap.
