Problem
Global plastic production is projected to more than double by 2060, leading to tens of millions of tonnes of plastic waste entering the environment each year. Conventional mechanical recycling often yields low‑quality material and cannot handle mixed or contaminated PET streams, limiting the ability to close the plastic loop.
Solution
GR3N offers a microwave‑assisted depolymerization (MADE) process that chemically breaks down post‑consumer PET waste back into its monomers, which are then repolymerized into high‑purity recycled PET. The technology operates at lower temperatures and with reduced energy consumption compared with traditional pyrolysis, enabling a more sustainable and economically viable recycling pathway. GR3N’s patented method produces recycled PET that meets or exceeds the specifications of virgin material, allowing it to be used in food‑grade packaging and other high‑value applications. The company is scaling the process through a first‑of‑its‑kind manufacturing facility slated for operation in 2027, supported by partnerships with industrial investors and recognized by the Solar Impulse Foundation for its efficiency and profitability.
Target Audience
Primary customers are PET resin manufacturers, beverage and food packaging companies, and large‑scale waste‑management firms seeking high‑quality recycled PET for closed‑loop product lines.
