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 this initiative is on the removal of organic and...

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...

Materiais renováveis obtidos a partir da biomassa para as tecnologias de armazenamento e conversão de energia eletroquímica (BioEESC)

PartnerFundação para a Ciência e a Tecnologia
BioEESC aims to develop highly cost-effective, safe, sodium solid-state battery and PEMFCs from biomass for energy storage and conversion applications. Novel class of green polymer electrolytes will be developed by a team with expertise in ionic conductors, polymers synthesis, recovery and purification of biopolymers and pigments from b...

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. Utili...
