Bridge Green and Hartree Sign Up to $1 Billion Lithium Carbonate Agreement

According to company reports, Bridge Green Upcycle and Hartree Partners have signed an eight-year commercial agreement covering lithium carbonate produced from recycled lithium-ion batteries, with an estimated value of $500 million to $1 billion at current market conditions.

Under the agreement, Hartree will have exclusive marketing rights for lithium carbonate produced by Bridge Green during the initial term and will purchase and market approximately 10,000 metric tons per year across all grades produced at Bridge Green facilities. The agreement can be renewed for an additional seven years. Bridge Green said the estimated contract value is based on current market conditions and is subject to delivered volumes and prevailing lithium prices.  

The commercial agreement coincides with an equity investment by Hartree in Bridge Green’s bridge financing round. The funding will support Bridge Green’s planned expansion of battery recycling and critical-mineral refining capacity in the United States and India, with Hartree expected to serve as the downstream marketing channel for future production.

Bridge Green commissioned its Circularity Center in Gummidipoondi, Tamil Nadu, in the second quarter of 2026. The facility has nameplate capacity of approximately 7,200 metric tons per year of lithium-ion battery input and is designed to recover critical materials from end-of-life batteries and battery manufacturing scrap.

The company plans to use proceeds from an upcoming Series A financing to develop fully integrated commercial refining facilities in the U.S. and India. The first lithium carbonate volumes covered by the Hartree agreement are projected for 2028.

Bridge Green uses battery recycling and critical-mineral recovery processes to produce black mass and other recovered materials. Resource Recycling reported that the company combines mechanochemical and hydrometallurgical processes to recover materials from lithium-ion batteries.

The agreement comes as battery recyclers and critical-mineral processors expand domestic recovery capacity. Hartree said critical minerals are a key part of its growth strategy, while Bridge Green said the long-term commercial commitment will support the deployment of additional recycling and refining capacity.

Hartree’s agreement with Bridge Green also adds a recycled lithium supply source to its broader critical-minerals portfolio. The company was previously selected as a supplier for Project Vault, a proposed U.S. Strategic Critical Minerals Reserve, according to the companies.
