GR3N closes €15.5M Series B to scale its chemical PET recycling technology

Lugano, Ticino, Italy

GR3N, the Swiss cleantech company revolutionizing PET/ polyester plastics and fibers recycling, announces the closing of a €15.5 million series B round. The round is led by 360 Capital, a leading Franco-Italian VC firm investing in Deep Tech and Climate Tech, with the participation of VP Textile as new investor. Growth Capital acted as financial advisor to GR3N.

The problem: 98% of recycling today is mechanical – and treats only 15% of PET

PET is one of the most widely used plastic materials in the world, with a market of 100 million tons. Today, 98% of recycling relies on mechanical technologies, which can only process transparent and light-blue bottles, just 15% of the total PET available. The remaining 85%, including textile fibres, films and coloured resins, ends up in landfill or incinerated.

At the same time, demand for recycled PET is accelerating alongside evolving regulations. The EU’s Packaging and Packaging Waste Regulation requires producers to meet a minimum recycled PET content of up to 30% by 2030 and up to 65% by 2040. In tandem, beverage industry brands have announced their own ambitious recycled content targets. Chemical recycling is the only technology capable of meeting this demand at scale.

GR3N’s solution: MADE, the most efficient depolymerization technology on the market

GR3N has developed MADE – Microwave Assisted DEpolymerization, a patented technology capable of processing 100% of PET waste – from both packaging and textile sources – with high yield and reductions in CO₂ emissions by up to 80% compared to virgin PET. Unlike competing technologies (glycolysis, methanolysis, dissolution), MADE has no feedstock limitations and produces food-grade monomers that can be recycled infinitely without any loss in performance.

GR3N holds 2 patent families covering the depolymerization process and 1 patent family on its proprietary equipment (PEQ).

MODUS: the world’s first industrial plant based on this technology

The proceeds from the round will be directed towards the development of MODUS, a first-of-a-kind plant with a capacity of 40,000 tons per year, located in Spain and developed in strategic partnership with Intecsa Industrial, a company part of Cobra IS industrial group, which leads the engineering and EPC execution. The project has secured a signed €35M Grant Agreement under the EU Innovation Fund (Large Scale Industrial Projects category), with financial closure expected in Q4-2027 and commercial operation planned for Q2-2030.

GR3N is pleased to welcome Martin Stephan as its new Chief Executive Officer. He brings over two decades of executive leadership experience in international business and technology, with a strong track record of driving growth and innovation across global markets.

“I am very excited to join this talented team with the goal to bring the Microwave Assisted Depolymerization technology to the market and make it the Best Available Technology for PET chemical recycling. With this round, and the support of our financial and industrial partners, we accelerate the construction of the First-Of-A-Kind plant operating our technology.” – Martin Stephan, CEO, GR3N.

“Textile waste is one of the most urgent, and most unsolved, problems in the sustainability transition. The fashion industry generates over 90 million tons of waste annually, polyester dominates global fiber production, and yet less than 1% of clothing is ever recycled back into clothing. The loop has never been closed because the technology to close it didn't exist. Until now.

What convinced us at 360 Capital is that GR3N has done the hard work. Not just proving the chemistry, but engineering a technology that handles the full complexity of real-world PET waste: blended fabrics, colored textiles, contaminated streams. No feedstock limitations. A clear path to industrial scale. MODUS will be the first proof point that microwave depolymerization can operate at the tonnages the market actually demands. The regulatory pressure is real. The demand from brands is real. What was missing was a technology capable of meeting both. We believe GR3N is it.” – Alessandro Zaccaria, Partner, 360 Capital.

“As VPTextile, we see in the collaboration with the European Technology Developer GR3N an innovative and sustainable solution for chemical recycling of polyester-containing workwear and protective wear. Thanks to the very high purity of the recycled building blocks TPA and MEG that GR3N achieves, we can guarantee high-quality recycled polyester as a raw material for our sustainable garments.” – Kees Timmermans, Textile Innovator, VPTextile.
