Plastic recycling has fallen brief. Solely about 9% of all plastic is recycled globally, which sounds fairly unhealthy till you examine it with textiles. Solely 0.5% of these are recycled.
One of many largest challenges is that textiles are seldom one materials. Buttons and zippers complicate issues, however spandex is even worse. Novel artificial blends have made for clothes that’s a dream to put on however a nightmare to recycle.
“The problem to recycling is that you may by no means predict your waste,” Stwart Peña Feliz, co-founder and CEO of MacroCycle, instructed TechCrunch. “Your waste has infinite variety of contaminants.”
MacroCycle has developed a shortcut, of types, that guarantees to make recycled plastic as cheap as virgin materials. The startup has devised a method to pluck fascinating artificial fibers from waste textiles, leaving all the things else behind. MacroCycle is a High 20 finalist in Startup Battlefield and is presenting at TechCrunch Disrupt in San Francisco.
Peña Feliz is aware of the potential pitfalls of plastic recycling properly. Earlier in his profession, he helped run ExxonMobil’s chemical recycling plant, which makes use of warmth to interrupt down plastic into less complicated hydrocarbons. It really works, however the course of is power intensive and spews a number of carbon dioxide.
“I noticed that firsthand and knew one thing needed to be performed,” he mentioned.
Quickly after he left Exxon, Peña Feliz determined to pursue an MBA and MIT. There, he met Jan-Georg Rosenboom, who as a postdoc had developed a novel method of recycling plastics. “After I noticed his expertise, I assumed it was too good to be true,” Peña Feliz mentioned.

The pair began turning that expertise right into a enterprise within the fall of 2022. The next spring, they had been chosen for a Breakthrough Vitality Fellowship to develop it additional. “We form of checked out one another and mentioned, ‘I assume we’re doing this full time,’” Peña Feliz mentioned. MacroCycle raised a $6.5 million seed spherical earlier this 12 months.
To grasp plastic recycling, it helps to know a bit concerning the materials’s chemistry. Plastics are polymers, that are lengthy chains of monomers, or repeating chemical constructing blocks. Most chemical recycling processes break plastic polymers down into smaller elements, together with monomers, to allow them to then rebuild them into one thing indistinguishable from virgin plastic.
MacroCycle differs as a result of it doesn’t break down polymers. As a substitute, it loops the polymer chains again on themselves, forcing them into rings referred to as macrocycles. These macrocycles stay behind as totally different solvents wash away contaminants, which themselves may very well be recycled. Later, the rings are reopened to reform the polymer chain. “As they open up the rings need to mix with one another, and in polyester, the longer the polymer, the upper the standard,” Peña Feliz mentioned.
“By not having to retrace all these steps once more, we’re capable of take a considerably extra power environment friendly method,” he added. MacroCycle’s course of makes use of 80% much less power than is required to make virgin polyester, whereas different chemical recycling processes use be 20% to 30% much less, he mentioned.
The startup is within the technique of establishing a bigger reactor, one which’s 2,000 occasions bigger than the one they had been utilizing two and a half years in the past, Peña Feliz mentioned. It’s massive sufficient to supply 100 kilogram (220 pound) batches of fabric for purchasers to pattern. MacroCycle is producing income from vogue manufacturers within the expertise, he mentioned.
“We’re snug of being one of many few, if not the one, public chemical recyclers that may declare that we will present this materials at value parity as soon as we construct our first industrial facility,” Feliz Peña mentioned.
He’s satisfied it’s the one method for recycled plastic to interchange fossil fuels within the business. “The underside line drives a number of innovation, and if you wish to have gamers like ExxonMobil change the way in which they do issues, it won’t occur from the within,” he mentioned. “I need to have the ability to create a expertise so economically engaging that the chance value is actually excessive for them to not undertake this new kind of answer.”
If you wish to hear from MacroCycle firsthand, and see dozens of extra pitches, attend beneficial workshops, and make the connections that drive enterprise outcomes, head right here to study extra about this 12 months’s Disrupt, held October 27 to 29 in San Francisco.
