Meta has signed a series of purchase commitments for low-carbon building materials across cement, steel, and recycled plastics.

The first deal it signed was with low-carbon cement company Sublime Systems for at least 180,000 tons of the company’s electrochemically produced cement. According to the company, the deal will support Sublime in building its first commercial-scale facility in Holyoke, Massachusetts. Sublime’s cement production process breaks down low-value rocks and industrial wastes into their constituents through an electrochemical process that bypasses the need for extreme heat, which typically requires burning coal or other fossil fuels.

Sublime has already gained Microsoft’s backing, signing a 623,000-ton deal with the hyperscaler in 2025. DCD profiled the company and the wider low-carbon cement sector earlier this year.

The deal closely follows an agreement Meta signed with Fortera, a low-carbon cement company, for the environmental attribute certificates (EACs) associated with approximately 200,000 tons of its low-carbon cement. Meta has also signed deals with low-carbon concrete producers CarbonBuilt and Amrize.

In the low-carbon steel sector, Meta announced a deal with Swedish firm Stegra. The multi-year deal is expected to support the firm’s production facility and help it validate its low-carbon steel-making technology. Further details on the deal were not disclosed.

Stegra is currently developing its production facility in Boden, Sweden, which aims to utilize green hydrogen – hydrogen created through renewable energy sources – to reduce the emission profile of the steel-making process. The site will span 270 hectares and be divided into two sections, one for iron and steelmaking, and another for a 700MW hydrogen plant. Stegra signed a deal with Microsoft in September last year, under which it will supply its low-carbon product to Microsoft’s data center equipment suppliers.

Within the recycled plastics sector, the company inked a long-term commitment with MacroCycle Technologies. The company, based in Cambridge, Massachusetts, utilizes chemistry and selective non-toxic reagents to return plastic waste into virgin-grade plastics. The deal with Meta will see the tech company purchase EACs from plastic recycling to help finance the company’s first commercial plant in the Southeastern US, which is slated to produce 5,000 tons of plastic per year. The deal was originally signed in September.

“Reaching net zero means advancing lower-carbon solutions across our supply chain and in the materials we use. We have been working to address emissions across our supply chain on materials like cement and steel, and our early procurement of materials from these sectors helped pave the way for the maturing markets we see now. We hope this transaction with MacroCycle will have a similar outcome in the plastics market,” said Devon Lake, head of Net Zero Strategy at Meta.

Finally, Meta announced the expansion of an agreement with electric vehicle freight company Nevoya. The companies partnered earlier this year on an initiative in Texas to deploy 40 Class 8 battery-electric trucks on a new all-electric Houston-Dallas route. The deal was signed in collaboration with the Center for Green Market Activation and Smart Freight Centre.

The expanded agreement will now include a California-to-Arizona route along I-10 interstate.

In a statement, Meta said: “By supporting heavy-duty electric trucks and dedicated charging infrastructure along critical transport routes, we’re helping bring cleaner air and quieter streets along freight corridors in Virginia, Texas, California, and Arizona. The permanent, open-access charging stations will support other commercial fleets along the corridor.”

“These commitments do more than secure materials and services for Meta – proving technologies at commercial scale makes them available to the entire market. That is the outcome we are working toward: supply chains where lower carbon cement, steel, recycled plastics, and electrified freight are standard options for any builder. Supporting domestic manufacturing capacity is one way that transition takes form, and we invite more buyers to build these markets with us,” the company said in a statement reflecting on all the signed agreements.
