Freight forwarders are being asked for greener transport, but most still do not have a simple way to sell it. Refine plugs into the forwarder’s operation and turns shipment data into a ready-to-sell low carbon offer. We bring pricing, sourcing, customer acceptance and documentation into one end to end workflow. The idea is simple: help freight forwarders build a new business line, earn more on every customer relationship and become the green partner their customers actually want to work with.

GLYON is developing a CO₂-powered textile-to-textile recycling technology to help brands, fiber producers, and recyclers solve the growing textile waste crisis with a breakthrough chemical recycling process that turns waste into virgin-quality raw materials for new fibers—without fossil fuels. We address the massive problem of textile waste, a global crisis where over 92 million tonnes of textile waste are discarded each year—most of it ending up in landfills or incinerated. This contributes to major pollution issues but also forces the textile industry to continue its dependence on virgin fossil-based materials. Our solution targets fiber producers, brands, and recyclers who need circular raw material solutions. Our CO₂-based chemical recycling process breaks down polyester textiles into building blocks and leaves other fibers like cotton intact. Both PET building blocks and cotton can be used to produce new, high-quality fibers without the need for virgin oil and reducing water consumption and CO₂ emissions.
