GR3N raises €15.5M as PET recycling moves toward industrial scale

GR3N has raised a €15.5M Series B to support its PET recycling technology.

What happened

The company is working on a microwave-assisted process for recycling PET, one of the most common plastics used in packaging and textiles.

Why it matters

Recycling has often struggled with quality, economics, and scale. Technologies that can improve material recovery could make circular supply chains more realistic.

The bigger picture

Climate tech is increasingly becoming an industrial technology story. Less glossy app, more chemistry, materials, and factories doing the hard work.
