CLOSER Public Newsletter Issue One

August 05, 2026

Welcome to the CLOSER Public Newsletter.

The transition to a more circular and resilient economy affects everyone. Many of the technologies we use every day, from smartphones and solar panels to electric vehicles and medical devices, depend on critical raw materials (CRMs) such as Silicon, Gallium, Indium, and Germanium. Yet the supply of these materials is increasingly challenged by resource scarcity, geopolitical tensions, and global supply chain disruptions.

This newsletter is designed for a broad audience, including citizens, students, researchers, businesses, policymakers, and sustainability professionals who want to better understand the role of critical raw materials in Europe’s green and digital transitions. In this newsletter, readers will find accessible insights into semiconductor and photovoltaic value chains, innovative recycling and recovery technologies, digital tools such as the Digital Product Passport (DPP), and key European policy insights. We will also share project achievements, industry perspectives, and upcoming events, helping to raise awareness and foster dialogue on building a more sustainable, circular, and resource-secure future for Europe.

About CLOSER

Project Scope

CLOSER stands for Circular raw materials for European open strategic autonomy on chips and microelectronics production. It is an I3 (Interregional Innovation Investments) project that aims to establish a European closed loop for semiconductors, organising the ecosystem for Critical Raw Materials from e-waste, back into sustainable chips and microelectronics.

Figure 1. CRMs challenge in Europe and the CLOSER solution.

Project Work Packages

CLOSER is structured around eight interconnected Work Packages (WPs) that cover the entire circular semiconductor value chain. A Work Package means a major subdivision of the project, from project coordination and e-waste collection to material recovery, semiconductor manufacturing, digital traceability, and market deployment. Each addresses a specific stage of the value chain while contributing to the project’s overarching goal of strengthening Europe’s circular semiconductor ecosystem.

Figure 2. The roles of CLOSER Work Packages.

The CLOSER Consortium

31 partners from eight countries in Europe, including Germany, the Netherlands, Sweden, Italy, Belgium, Denmark, Lithuania, and Greece, are working together to build and scale a resilient European circular supply chain for semiconductors.

Geopolitical Vulnerabilities of Critical Raw Materials and Europe's Path to Strategic Autonomy

Silicon (Si), gallium (Ga), indium (In), and germanium (Ge)are among the most important materials used in semiconductor manufacturing. More broadly, these and other CRMs underpin virtually all industrial value chains, from raw material extraction and processing to advanced manufacturing. They are essential for clean and digital technologies, including semiconductors, batteries, renewable energy systems, electric vehicles, and energy-efficient solutions, making them crucial for achieving Europe’s industrial, climate, and sustainability ambitions.

Despite their strategic importance, Europe has limited domestic access to many of these materials. For example, it was estimated that Europe can provide only 1% of the raw materials needed to produce the batteries needed for the Green Deal.As a result, the continent relies heavily on imports of raw materials and electronic components from the Far East and the United States. Since many CRMs are sourced from a limited number of countries, geopolitical tensions, trade restrictions, and supply chain disruptions pose significant risks to Europe’s industrial competitiveness and technological sovereignty. In addition, Europe has lost considerable expertise and industrial capacity over recent decades due to the relocation of manufacturing activities and the discontinuation of key technological processes.

Against this backdrop, the development of a resilient European supply chain for recovering and reusing semiconductor materials from electronic and industrial waste is both timely and necessary. The overarching objective of CLOSER is to establish a pan-European network for collecting, recycling, and recovering semiconductor-based components, increasing the use of secondary raw materials in Europe’s semiconductor value chain and reducing dependence on external sources. By developing innovative technologies for the recovery and recycling of critical raw materials, CLOSER helps transform waste streams into valuable resources that can be reintroduced into semiconductor manufacturing.

CLOSER will showcase how the principles of circularity and urban mining can be applied to convert end-of-life materials and components from regional smart specialisation sectors into valuable secondary resources. Specifically, the project demonstrates the recovery of:

  1. Secondary semiconductor critical raw materialsfor use in microelectronics manufacturing; and
  2. Remanufactured componentsfor strategic European industries that are highly dependent on external supply chains, including automotive, aerospace, renewable energy, healthcare, and computing.

The figure below illustrates the key challenges facing Europe’s semiconductor sector and how CLOSER is contributing to the solution.

Figure 5. CRMs challenge in Europe and the CLOSER solution.

Recovering Critical Semiconductor Materials: Silicon, Silicon carbide, Gallium and Indium

Semiconductors are at the heart of modern technologies, powering everything from smartphones and data centres to solar panels and electric vehicles. A key opportunity lies in the recovery of these valuable materials from electronic waste and end-of-life photovoltaic (PV) modules. Rather than treating discarded electronics as waste, they can be viewed as an urban mine containing critical raw materials that can be recovered and reintroduced into manufacturing processes.

Siliconis the foundation of most semiconductor devices and crystalline photovoltaic cells. Yet despite its importance, the recycling rate of silicon from end-of-life products remains extremely low. Recovering silicon requires several processing steps, including collection, dismantling, removal of glass and other materials, purification, and recrystallisation before it can be reused in new applications.

Silicon carbide (SiC)is becoming increasingly important for advanced power electronics used in renewable energy systems, electric vehicles, and high-performance electronic devices. Through CLOSER’s revamping and reclaiming activities, valuable SiC substrates are recovered from defective manufacturing wafers and prepared for reuse in new semiconductor production. This approach extends material lifetimes, reduces waste, and decreases the need for virgin resources.

The recovery of gallium and indiumpresents additional challenges. Both materials are typically obtained as by-products of other mining activities, occur in low concentrations, and are embedded within complex products and global value chains. Gallium is widely used in GaAs and GaN semiconductors, LEDs, and advanced photovoltaic technologies, while indium is essential for display technologies, transparent conductive coatings, and CIGS solar cells. Current recycling processes often prioritise the recovery of more abundant and valuable metals, such as copper, causing gallium and indium to be lost as impurities or discarded in processing residues.

To address these challenges, CLOSER is trying to improve collection and sorting approaches, targeted pre-treatment, selective extraction and purification processes, and advanced material characterisation techniques. The project is also investigating whether recovered materials can meet the stringent quality requirements needed for semiconductor manufacturing and be transformed into new wafers and electronic components.

Digital Product Passports (DPP): Enabling Transparency Across Circular Value Chains

Secondary critical raw material value chains stretch across many actors and countries, from collectors to recyclers, chemical producers, and electronic manufacturers. Each actor holds only a piece of a product’s history. This fragmentation makes it difficult to trace where secondary materials originate, how they have been processed, and how or if they can be safely reused or recycled.

The Digital Product Passport aims to close this gap by providing a shared, standardised and transparent record that follows products and materials throughout their lifecycle. Within this context, for an interregional innovation project such as CLOSER, the DPP is a critical cornerstone. It will be used to link otherwise disconnected recycling and manufacturing steps, support compliance with the EU CRM regulatory framework, and build the trust needed for the successful integration of secondary raw materials in the European supply chains.

With the successful completion of the CLOSER project, Europe will have a transparent and verifiable information repository on CRMs, promoting circularity and securing its strategic autonomy.

Regulatory Framework and Policy Developments

Critical Raw Materials Act, EU Chips Act, Waste Shipment Regulation, and PFAS Regulation: Potential Impacts on the Semiconductor Industry and CLOSER

The European Union is rapidly strengthening its policy framework to secure access to critical raw materials while building resilient, circular and competitive industrial value chains. At the heart of this agenda is the Critical Raw Materials Act (CRMA), which sets ambitious 2030 benchmarks to increase domestic extraction, processing and recycling capacity, while reducing dependence on any single third-country supplier. Together with the EU Chips Act, these measures are designed to reinforce Europe’s strategic autonomy in semiconductors and other key technologies.

Complementary legislation is equally important. The revised Waste Shipment Regulation facilitates the development of high-quality recycling within the EU by tightening exports of valuable waste streams to non-OECD countries and improving traceability. Meanwhile, the forthcoming Digital Product Passportwill make information on material composition, repairability and recyclability more accessible throughout product lifecycles, creating new opportunities for recovering valuable secondary raw materials.

The infographic developed within the CLOSER policy work also highlights barriers beyond legislation. Industrial quality standards frequently favour new components over validated reused electronics, while accredited EU-wide testing methods for second-life semiconductor components are still lacking. Mandatory Digital Product Passports for ICT and electronics are not expected until around 2029, meaning recyclers must continue to identify valuable materials in legacy products without digital material data.

Figure 8. Policy challenges for CLOSER.

At the same time, the European semiconductor industry is closely monitoring the ongoing debate surrounding the proposed restriction of per- and polyfluoroalkyl substances (PFAS), a broad group of chemicals valued for their resistance to heat, chemicals, and corrosion and widely used in semiconductor manufacturing processes and production infrastructure. Like the industry as a whole, our project partner Freiberger is significantly affected by these discussions. It remains uncertain whether, and to what extent, PFAS that are essential for semiconductor production facilities and infrastructure will continue to be permitted. Should these critical uses not be exempted, the European semiconductor sector could face severe disruption. In such a scenario, the industrial-scale implementation of innovations developed within projects such as CLOSER could also be significantly constrained in Europe.

All these policy developments are highly relevant to the CLOSER project. CLOSER highlights the opportunities created by Europe’s circular economy agenda, but also the importance of ensuring that future regulations enable, rather than constrain, the industrial deployment of sustainable semiconductor technologies.
