At GreenPATH, we are building a new, sustainable strategy for plastic recycling — one that unites computational solvent design with biocatalytic depolymerization. 

Our key innovation lies in the identification and validation of renewable, low-impact solvents. Using AI-assisted COSMO-RS screening, we select solvents capable of removing both organic and inorganic additives from plastic packaging waste — safely and efficiently. 

We are developing and optimizing pretreatment protocols for different types of polymers. These protocols are designed not only to remove additives, but also to allow recovery and reuse of both solvents and valuable compounds. 

Once the plastic is clean, enzymatic depolymerization can work more effectively, converting polymers into high-purity monomers that can be reused to make new materials. 

GreenPATH promotes sustainable plastic recycling by replacing harmful additives and conventional solvents with renewable, low-impact alternatives.  

It aims to reduce environmental impact, energy use, and raw material dependency, while supporting the reuse of valuable components. 

By combining computational tools and enzymatic depolymerization, the project enables a more efficient, selective, and eco-friendly process.

GreenPATH contributes to the circular economy, supports the creation of green jobs, and aligns with UN Sustainable Development Goals (SDGs) 12, and 13 and the Portuguese Circular Economy Agenda.
