Utilisation of the LARCODEMS device for heterogenous plastic pre-sorting in waste recycling

The increasing generation of plastic waste presents a major environmental challenge. This study evaluates the LARCODEMS device, originally designed for coal sorting, for its effectiveness in separating plastic mixtures. Experiments were conducted using plastic samples with known densities and aqueous salt solutions as separation media. Results showed that LARCODEMS achieves high separation efficiency even with minimal density differences. Further tests with real plastic waste from shredded electronic equipment confirmed effective separation of metals from plastics, validated by chemical analysis of fractions. These findings suggest that LARCODEMS offers a promising alternative to hydrocyclones for improved plastic waste sorting and recycling.

Probabilistic Plastics Flow Analysis of WEEE in Europe

Waste electrical and electronic equipment (WEEE) is one of the fastest-growing and most complex global waste streams. In the EU, collection rose 68% between 2012 and 2022, outpacing treatment by 11% due to its heterogeneous and toxic composition—average products contain 69 elements, including hazardous substances. Plastics, over 20% of WEEE mass, pose major treatment challenges. EU measures like the WEEE Directive and the Circular Economy Action Plan target improved plastic management, with recent focus on modeling plastic flows to link waste streams back to the plastics industry. A new two-part framework addresses key data and variability issues: (1) a PostgreSQL database harmonizing 314,000 data points from 120+ sources in 50 countries over 40 years, and (2) a Bayesian material flow analysis incorporating uncertainty into trend estimates. The aim is to help close the gap between 5 million tonnes of WEEE collected annually in the EU and only 800,000 tonnes recycled, advancing circular economy goals.

Recycling of sustainable automotive structural composites via pyrolysis, technical and climate impact evaluation

In the Ground Zero project, the full value chain for sustainable structural composites in the automotive sector was evaluated in terms of readiness and climate impact. Recycling of end-of-life composites was assessed through analytical and lab-scale pyrolysis from both technical and environmental perspectives. Two demonstrators were studied: a truck side skirt made of flax fibre and polypropylene (PP), and a car front header of glass fibre and PP. Additional materials such as PA6, PA11, and thermoset polyester were also tested. Results showed that material type influenced pyrolysis outcomes—glass fibres could be reused, flax fibres converted to bio-oil, and polymers recovered as oil or wax for use in fuel or chemical production. Pyrolysis offers a more climate-friendly alternative to incineration.

What are the main sustainability challenges for electric vehicle battery supply chains, and is European policy ready to address them?

The transition to electric vehicles (EVs) is vital for decarbonising transport, but growing demand for lithium, cobalt, and nickel poses major sustainability challenges. This study identifies 65 key factors affecting EV battery supply chains through a literature review, expert interviews, and a stakeholder survey. These span political, economic, social, technical, legal, and environmental (PESTLE) domains, with policy and legislation as key drivers of circularity. A comparison with European policy documents shows that while environmental and technical issues are well covered, social aspects are often neglected. The study highlights the need for more aligned and inclusive policy frameworks to support sustainable and circular battery supply chains.

Portable Battery Design for Environmental Sustainability and Circularity

In line with the EU’s New Battery Regulation (2023/1542), this study aims to assess the environmental performance of explorative portable battery designs, considering variations in pack design, pack material, and cell chemistry. With three alternatives for each of the three design aspects, a total of 27 (3³) explorative battery designs were generated and subjected to life cycle assessment (LCA). The results indicate that cell chemistry is the main environmental contributor, with lithium iron phosphate exhibiting the lowest impact. An alternative pack design using mechanical fasteners also demonstrated an environmental improvement due to the avoidance of adhesives and potting compounds. This explorative design approach, coupled with LCA, contributes to operationalizing sustainable and circular batteries, offering holistic and actionable guidance for manufacturing companies.

Selection of residual biomass for its conversion into a suitable biocarbon product for the metallurgical industry

Steelmaking via electric arc furnaces (EAF) can lower emissions but still needs renewable carbon sources. The BioReSteel project explores biochar (BC) from low-value wet biomass—garden waste (GW), olive pomace (OP), and organic municipal waste (OFMSW)—as a fossil carbon substitute. Biomass is treated by hydrothermal carbonization and pyrolysis, and BC quality is assessed by heating value, ash, and phosphorus (P) content. BC_OP shows lowest ash (8 wt%) and moderate P, making it suitable for EAF; BC_GW also performs well. BC_OFMSW, with high P (20%), is better for fertilizer after P extraction. Phosphorus, while detrimental to steel quality, is an economically valuable critical raw material. Pyrolysis boosts fixed carbon and heating value but raises ash. BC suitability depends on feedstock availability, logistics, and P market value. Integrating BC into steelmaking offers sustainability gains and supports industrial symbiosis.

Increasing Resource Efficiency for Sustainable Steel Production by Agglomeration of Mill Scale and Hydrochar Derived from Green Waste.

The steel industry is aiming to improve resource efficiency by utilising secondary materials, such as green waste hydrochar, to replace fossil carbon in steelmaking. The RFCS BioReSteel project focuses on utilising municipal green waste, including both pristine and pyrolysed hydrochar, along with mill scale residues, to create mill scale-hydrochar briquettes. These briquettes are top-charged into the Electric Arc Furnace (EAF) for steel production, thereby increasing resource efficiency and material circularity. The mechanical strength of the briquettes is vital for EAF top charging. The amount of hydrochar added influences this strength. Green waste hydrochar (GWH) and pyrolysed hydrochar (PGWH) can be incorporated at rates of up to 20% and 25%, respectively.

Sustainable Recovery and Upcycling of Graphite from Spent NMC Lithium-Ion Batteries

This study presents a process to selectively recover and upgrade graphite from spent lithium-ion batteries with NMC cathodes. Acid leaching removes all metallic components, yielding graphite-rich residue. Residual PVDF binder and carbon black are eliminated by hot DMSO extraction, acetone rinsing, and water-based cleaning. The purified graphite undergoes hydrothermal treatment with KOH to intercalate potassium ions and expand interlayer spacing, followed by ultrasonication to produce few-layer graphite sheets. Characterization by ICP-OES, FTIR, XRD, Raman, SEM, and BET confirmed the removal of contaminants and structural modification. This approach reduces environmental impact and produces high-purity exfoliated graphite for applications in energy storage, composites, and environmental remediation, supporting circular economy strategies.

Incineration Ashes and Recovery of Nutrients

Currently, the ashes from incineration of municipal solid waste, biomass, and sewage sludge incineration are underutilized in the EU due to a lack of technical solutions, symbiotic value chains, and coverage by the EU regulations. The EU-funded project AshCycle explores how incineration ashes from municipal waste, biomass and sewage sludge can become valuable secondary resources. By developing novel technologies for leaching, adsorption and extraction, the project enables recovery of heavy metals, rare earth elements, and nutrients. A key focus is on using ashes directly or as activated materials for recovering nutrients from wastewater. The project also demonstrates how Industrial-Urban Symbiosis can support circular value chains. This presentation will outline the status of the research and report the most important and promising findings.

Increased resilience through smarter utilization of incineration ashes

In a rapidly changing world, where conflicts, supply chain disruptions and trade embargos are the new normal, building resilience has become a key priority. One often overlooked opportunity lies in the ashes from incineration. Instead of treating these ashes as mere residues, they can be transformed into a source of increased resilience. Nutrients needed for our food production, precipitation chemicals needed for our drinking water as well as critical and strategic raw materials needed for our industrial production can all be recovered from incineration ashes. This presentation will highlight opportunities, challenges, and strategic importance of these recoveries, while also sharing reflections on what it takes to move from promising concepts to commercially available solutions.

Resource recovery in MSWI fly ash/APCr treatment: techno-economical approach and environmental perspective

Fly ash and/or air pollution control residues (both here referred to as FA) are the solid residues produced in municipal solid waste incineration (MSWI) plants. FA is a hazardous waste due to its high content of toxic elements, soluble salts, and organic pollutants. However, the quantity produced and the content of valuable components make this material a suitable secondary source for recovery. In general, hydrometallurgical treatment to recover salts and metals (mainly Zn) seems to be the most promising way to treat FA. The main products of these processes are usually pure Zn (FLUREC technology) or Zn-rich filter cake (FLUWA and HALOSEP). However, more products can be obtained within the process if it is designed appropriately. The presentation provides a summary of the necessary modifications and the design of an acid extraction process aimed at producing a Zn-rich filter cake, gypsum, industrial salts, and desalinated water, which has the potential to be reused in the technology.

Electrodialytic Separation of Heavy Metals from MSWI Fly Ash

Municipal solid waste incineration generates fly ash, a hazardous waste containing heavy metals that pose environmental risks. Effective, sustainable extraction and recovery strategies are needed to manage this issue. This study investigates electrodialytic separation as a promising technique for extracting these metals. This study aims to determine how ash characteristics and pretreatment methods impact the electrodialytic separation of heavy metals. Two distinct ash sources- acid-washed desalted ash (DA) and mixed raw ash (MRA) – were used, with an additional water-washed MRA (WWMRA) sample to assess pretreatment effects. Experiments were conducted in a three-compartment cell at varying current intensities (25-150 mA). The results showed that increasing current intensity generally enhances extraction efficiencies, with Cu and Zn exceeding a 75% target extraction efficiency at higher intensities. Overall, MRA recorded the highest extraction efficiencies for Cu and Zn with the lowest energy consumption, while WWMRA excelled in As extraction, and DA showed the highest Pb extraction but was the most energy-intensive. The study concludes that ash source and pretreatment strategy significantly influence electrodialytic separation performance, which is critical for optimizing metal recovery from MSWI fly ash.

A pragmatic methodology to prioritise critical raw material recovery: Belgium as a case study

In 2023, 34 materials were identified as critical raw materials (CRMs) for the EU, based on their high supply risk and strong economic importance. Recycling and other circular strategies are seen as a way to mitigate criticality. This work presents a pragmatic methodology to prioritise product streams for CRM recovery at a product’s end-of-life. The methodology is demonstrated for batteries in Belgium.

Recovery of CRMs as battery-grade materials by sustainable technologies

Waste from the production of batteries comes in the form of “off-specifications” when the cathode material is tested and does not meet the quality requirements of battery applications. This secondary resource has significant potential to be recycled in the battery value chain if efficient technologies for the recovery of the CRMs containing this waste are developed. Advanced solvometallurgy coupled to organic-based membrane electrolysis is a novel approach proposed for the valorization of lithium as a battery-grade Li2CO3 and the side-production of cobalt, nickel and manganese from waste cathode material. The studied solvometallurgical process relies on low-footprint organic leaching solutions with high Li selectivity and yields at low temperature, and the reusability of the organic solvents. The lithium containing leachate is subject to electrolysis tests using organic-based membranes in the experimental cell set up. Very good results in terms of Li yield migration to the cathode are achieved with the simultaneous recovery of the organic extractant. In addition, a carbonation method producing high purity grade lithium carbonate was established and tested.

Towards Circularity: Green Recovery of Strategic Metals and Fluorinated Polymers from LIBs and PEM Electrolysers

The rapid growth of electric vehicles and renewable energy has increased demand for critical raw materials like lithium, cobalt, nickel, and iridium. End-of-life lithium-ion batteries (LIBs) and PEM electrolysers are valuable secondary resources, but current recycling methods are inefficient and environmentally taxing. This research from CIIAE proposes an integrated recycling approach using green hydrometallurgy, solvometallurgy, and advanced solvents—including supercritical CO₂ and deep eutectic solvents (DES). A key focus is on recovering not only metals but also functional fluorinated polymers like PVDF and PFSA, enabling their reuse in new electrode and membrane systems. The goal is to create scalable, low-impact, closed-loop recycling processes aligned with circular economy principles and industrial needs.

Efficient solvometallurgy approaches for the recovery and reuse of CRM’s from EoL libs

As part of the European RENOVATE Project (WP4: “CAM Recovery – Solvometallurgy and Direct Recycling”), this study investigates the use of a ternary deep eutectic solvent (DES) made from choline chloride, lactic acid, and tartaric acid for recovering lithium, nickel, manganese, and cobalt. Recovery tests were first done with commercial NMC 811 cathode material, followed by trials using black mass from spent batteries. The DES was optimized via mixture design, and thermally assisted extractions were conducted for one hour. Metal recovery rates were measured using ICP-OES. The most efficient DES composition was then used for black mass recovery, and the resulting precipitate served as precursor material for resynthesizing second-life cathodes.

Towards a circular future – Material recycling of fibre reinforced polymers

Fibre-reinforced polymers (FRPs) combine high strength with low weight and are widely used in transport and construction. Their complex composition, however, makes recycling difficult, and most waste is currently landfilled or incinerated. This project develops cost-efficient, sustainable methods to recycle thermoset FRPs through pyrolysis, enabling recovery of both fibres and valuable chemicals. Waste from boat masts, hulls and bathroom units has been characterised and pyrolysed at laboratory and demonstration scale, with process parameters evaluated for their effect on product quality. Recovered fibres are reused in new FRP materials, while molecules from the pyrolysis oil are purified and used to synthesise fresh resins. Contaminants are managed through targeted strategies. The full recycling chain is assessed for carbon footprint and techno-economic viability, supporting industrial circularity and future commercialisation.
