Old Threads,
New Possibilities.
MacroCycle upcycles textile waste into 100% polyester resin at the lowest cost.
What feels like magic is not mystery. It's advanced science, engineered to solve the impossible.

THE TEXTILE WASTE PROBLEM
Less than 1% of textiles are recycled every year.
Mechanical recycling requires clean, mono-material textiles and cannot effectively handle the complexity of real-world textile waste.
Most chemical recycling technologies are energy- and capital-intensive, making it difficult to produce recycled materials at competitive cost.

It's not magic. It's science.
Pure polymer. Low cost. No compromise.

Instead of recycling by breaking bonds, we make new bonds.
MacroCycle is engineering inevitability. Through advanced science, our technology transforms chaotic textile waste into pure polyester resin.
Our process is called SolvoGenesis™

solv·o·gen·es·is
[ sälvo ˈjenəsəs ] noun
Signifying the genesis of bonds, rather than the destruction of bonds, or lysis, that is common to other recycling technologies, SolvoGenesis™ uses proprietary solvent systems and macrocyclic chemistry to bring waste polymers back to life.
