Stwart Peña Feliz MBA '23 co-founded MacroCycle, a startup that has “devised a way to pluck desirable synthetic fibers from waste textiles, leaving everything else behind,” reports Tim de Chant for TechCrunch. “MacroCycle differs because it doesn’t break down polymers,” explains Tim de Chant. “Instead, it loops the polymer chains back on themselves, forcing them into rings called macrocycles. Those macrocycles remain behind as different solvents wash away contaminants, which themselves could be recycled. Later, the rings are reopened to reform the polymer chain.”
