Green Plastic recycling: Additives removal THrough renewable solvents to enhancing the enzymatic depolymerization (GreenPATH)
PartnerFundação para a Ciência e a Tecnologia
GreenPATH aims to develop a sustainable pretreatment process that combines high-pressure solid-liquid extraction (HP-SLE) with low-cost, renewable solvents, namely biosolvents and deep eutectic solvents (DES), to extract the additives in a key step prior to enzymatic depolymerization. The focus of thi...Hydrophobic Eutectic Solvents for Tailored Metal Separation and Recycling (DESignSX)
CoordinatorEuropean Comission
Sustainable metallurgy is environmentally sound and allows reclaiming metal value from end-of-life devices, thereby closing the resource loop. However, the separation of lanthanides (Ln) poses challenges due to their subtle property variations, which affect their recycling economics despite growing demand. In this context, the ERC-funded DESignS...NGS - New Generation Storage (NGS (WP1-BPE23 Li REGENERATION CYCLE))

PartnerIndustry National
The New Generation Storage (NGS) Innovation Pact is completely aligned with the European Union's energy transition strategy until 2040, and the challenge for the complete electrification of mobility by 2035. Based on a model structured in 8 Work Packages that cover the entire value chain of component production, battery packs and r...NGS - New Generation Storage (NGS (WP5-BP24 BATTERY CATHODE RECYCLING))

PartnerFundação para a Ciência e a Tecnologia
PlatILPlus is an FCT-funded research project that aims to develop eco-friendly yet readily applicable methodologies for the valorization of Spent Automotive Catalytic Converters (SACC) through hydrometallurgical processes. The project focuses on the recovery and separation of Platinum Group Metals (PGM) and Rare Earth Elements (REE) to ...REcycling of low Value components using high purity pre-treatment, dIrecT recycling And green hydrometallurgical approaches for recycling of Lithium Ion and Sodium Ion BatteriEs (REVITALISE)
PartnerEuropean Comission
As the need for effective battery waste management grows, NMC, LFP and Na-ion batteries contribute significantly to this challenge, accounting for 85 % of the problem. Traditional recycling methods prove inadequate, lacking efficiency and eco-friendliness. That's where the EU-funded REVITALISE project comes in, with an innovative solution.
