At MacroCycle, we’re building a new approach to textile recycling. Where currently most textiles after use are landfilled or incinerated, our SolvoGenesis^TM technology transforms low-value textile waste back into high-quality polyester fibers. This technology will reduce landfill waste as well as production emissions and close the loop towards truly circular textiles. Unlike traditional chemical recycling, our process bypasses the energy- and carbon-intensive breakdown steps, enabling MacroCycle to deliver a cleaner, cheaper, and more efficient solution for a truly circular economy.
