Peter – Polyester, renewed
With PETER, chemical polyester recycling becomes a flexible, scalable and licensing technology, capable of transforming textile and plastic waste into high-quality PET.
Who we are
PETER is an innovative chemical recycling process for polyester, capable of transforming mixed textile waste and hard-to-recycle packaging into high-quality PET. This proprietary technology overcomes the limitations of traditional recycling, making a tangible contribution to waste reduction and the transition to a circular economy.
PETER was developed and is promoted by While True, a cleantech startup founded in 2021 with the mission to innovate the recycling sector and accelerate environmental sustainability. In addition to developing PETER, While True operates as an R&D center and technology provider, offering tailored solutions for the recycling and plastics industries.
Thanks to strong industrial and academic partnerships, we bring sustainable and scalable solutions to market, developed through a truly ESG-driven approach and designed for large-scale adoption.
