GR3N raises €15.5M Series B to scale PET chemical recycling

GR3N, the Swiss
cleantech company advancing the recycling of PET and polyester plastics and
fibres, has closed a €15.5 million Series B funding round. The round was led by
360 Capital, with participation from new investor VP Textile. Growth Capital
acted as financial advisor to GR3N.

The funding
comes as demand for recycled PET continues to accelerate. While PET is one of
the world’s most widely used plastics, current recycling technologies can
process only a fraction of available PET waste, leaving most textile fibres,
films, and coloured materials unrecycled. At the same time, increasingly
stringent regulations and sustainability commitments from major consumer brands
are driving the need for scalable solutions capable of processing a broader
range of PET waste streams.

To address this
challenge, GR3N has developed MADE (Microwave-Assisted Depolymerisation), a
patented chemical recycling technology that can process all types of PET waste,
including both packaging and textile materials. The technology delivers high
material recovery yields while reducing CO₂ emissions by up to 80 per cent
compared with virgin PET production.

Unlike
alternative recycling methods such as glycolysis, methanolysis, and
dissolution, MADE has no feedstock limitations and produces food-grade monomers
that can be recycled repeatedly without any loss of performance. GR3N’s
intellectual property portfolio includes two patent families covering the
depolymerisation process and an additional patent family protecting its
proprietary equipment (PEQ).

The proceeds
from the Series B round will support the development of MODUS, GR3N’s first commercial-scale recycling plant.
