Meta backs plastics recycling startup MacroCycle with carbon credits deal
MacroCycle, a three-year-old plastics recycling startup based in Cambridge, Massachusetts, announced a deal with Meta on Tuesday that will help fund its first commercial plant in the U.S. Under the agreement, Meta will pay MacroCycle for environmental attribute credits (EACs) representing avoided carbon emissions, allowing Meta to count these reductions toward its own carbon footprint. This is Meta's first such deal. MacroCycle's technology uses solvents to dissolve and purify PET from waste streams, including textiles, producing high-quality recycled plastic with 80% fewer carbon emissions than virgin PET. The demonstration plant will produce 5,000 metric tons of recycled plastic annually. The revenue from the EACs will support plant construction, and Meta hopes to foster a market for low-carbon materials used in its supply chain.

Meta Leaves RE100 Amid Natural Gas Buildout
Meta confirmed it has left RE100, a corporate renewable-energy initiative run by the Climate Group, after roughly a decade of membership. The exit coincides with Meta funding at least a dozen natural gas power plants over the past year — including 10 plants for its Hyperion project that together will generate about 7.5 gigawatts. RE100 recently tightened reporting guidance for members, and Meta says it still intends to match its data-center electricity use with 100% clean and renewable energy, typically via energy attribute certificates. Competitors including Apple, Google and Microsoft remain RE100 members.
Meta plans to sell excess AI compute
TechCrunch reports that Meta is planning a cloud infrastructure business to sell access to excess AI compute and hosted models, a move that would compete with major cloud providers such as AWS, Google Cloud and Microsoft Azure. Bloomberg first reported the plans, which mirror recent moves by SpaceX/xAI to lease data-center compute to third parties (including deals with Anthropic, Google and Reflection AI). Meta has committed large capital to AI infrastructure (reported at $182.9 billion in future spending) and is reportedly considering a business unit dubbed “Meta Compute,” led by Santosh Janardhan, Daniel Gross and Dina Powell McCormick. Bloomberg says Meta may copy CoreWeave’s raw-compute leasing model and also offer access to hosted models (including its closed-weight Muse Spark). The strategy aims to monetize excess capacity as direct demand for Meta’s own AI services remains limited and as industry debate continues over compute demand and chip depreciation.
Meta Eyes Cloud Business, Wall Street Accepts Lower Margins
Meta is preparing to sell excess computing capacity to external customers, sparking investor enthusiasm even as the company would move into a lower-margin business than its core advertising operations. CNBC reported Jim Cramer confirmed the plan while Bloomberg said Meta is debating whether to sell raw compute or offer access to AI models hosted on its infrastructure. The announcement sent Meta shares sharply higher, as investors look for ways to monetize the company’s large AI and data-center investments. Analysts say Meta is likely to pursue a niche strategy similar to neocloud providers rather than challenge hyperscalers; concerns remain that building an enterprise cloud sales organization and competing on raw compute would dilute Meta’s high margins and require significant time to reach profitability.
