Plastics recycling startup MacroCycle introduced a brand new cope with Meta on Tuesday that can assist velocity the event of its first industrial plant.
Three-year-old MacroCycle, based mostly in Cambridge, Massachusetts, has developed a novel strategy to course of plastic waste that strips it of contaminants, making the ensuing recycled materials extra engaging to prospects. The startup says its know-how generates 80% fewer carbon emissions than new, non-recycled virgin PET plastic (a typical sort of plastic utilized in bottles, containers and textiles). MacroCycle was a Prime 20 finalist within the 2025 Startup Battlefield competitors at TechCrunch Disrupt in San Francisco.
Below the phrases of the settlement, Meta can pay MacroCycle for the rights to these prevented emissions, which lets Meta rely the discount towards its personal carbon footprint, which is rising dramatically on account of the AI growth. A Meta spokesperson confirmed that that is the primary such deal the corporate has signed. MacroCycle gave TechCrunch an unique preview of the information.
Funds for what are often known as environmental attribute credit (EACs) will present MacroCycle with a income stream that may assist help the development of the brand new plant, which can be constructed within the U.S.
Meta’s curiosity goes past the credit themselves. It hopes to assist create a marketplace for low-carbon supplies like plastics, that are utilized in its provide chain for issues like packaging and {hardware}. As that market grows, broader entry to these supplies ought to assist decrease the corporate’s general carbon footprint.
MacroCycle says its demonstration plant can be able to producing 5,000 metric tons of recycled plastic per 12 months. The corporate’s course of works by dissolving and purifying PET that’s current in a variety of waste streams, together with textiles, which have one of many lowest recycling charges of all supplies at 0.5%.
The startup’s course of loops plastic polymers again on themselves, creating rings referred to as macrocycles, which is the place the corporate will get its identify. Solvents wash away contaminants, leaving the macrocycles behind. The loop is then opened, and the polymers will be linked collectively to type higher-quality plastics. The result’s a cloth that’s indistinguishable from new plastic.
MacroCycle’s use of solvents as an alternative of warmth is a serious supply of its vitality financial savings, which must also lead to decrease prices, too. The corporate’s purpose is to provide recycled textiles domestically at costs that compete with these from abroad suppliers. The U.S. textile manufacturing trade has been hollowed out over the past 25 years, with employment within the sector down 85%.
MacroCycle is at present working to safe consumers for the fabric that its first plant will produce. The cope with Meta ought to make subsequent agreements with different corporations simpler to acquire, MacroCycle co-founder and CEO Stewart Peña Feliz advised TechCrunch. Future vegetation, he added, can be able to producing 50,000 metric tons of fabric per 12 months.
