Cleantech startup Graphyte and financial giant JPMorganChase have entered into a major agreement in the United States for the purchase of 60,000 tons of durable carbon dioxide removal (CDR) credits over the next decade. The deal, announced in April 2026, centers on Graphyte’s proprietary “Carbon Casting” technology, which focuses on the permanent sequestration of compressed biomassBiomass is a complex biological organic or non-organic solid product derived from living or recently living organism and available naturally. Various types of wastes such as animal manure, waste paper, sludge and many industrial wastes are also treated as biomass because like natural biomass these More. This collaboration represents a significant step in the financial sector’s shift toward securing high-integrity, long-duration carbon removal solutions to address residual operational emissions that cannot be eliminated through traditional decarbonization.

The primary challenge addressed by this agreement is the urgent need for scalable and economically viable carbon removal technologies to meet global net-zero targets. Traditional carbon offsetting has faced criticism regarding durability and verifiable impact, while many emerging high-tech solutions like Direct Air Capture remain energy-intensive and expensive to deploy at scale. For global institutions like JPMorganChase, finding “high-quality” credits that offer permanent storage while fitting into an immediately deployable corporate sustainability strategy has been a critical hurdle.

Graphyte’s solution utilizes a process called Carbon Casting, which leverages the natural photosynthesis of plants to capture carbon. The company collects residual biomass from timber and agricultural operations—materials that would otherwise decompose and release greenhouse gases—and dries it to halt microbial activity. This biomass is then compressed into dense blocks, wrapped in an impermeable, environmentally safe polymer barrier, and stored in monitored underground sites. This approach preserves nearly all the carbon captured in the biomass while consuming significantly less energy than other technical removal methods.

The outcomes of this partnership extend beyond simple carbon sequestration, providing measurable ecological and economic benefits to local communities. Credits for this deal will be supplied by Project Loblolly in Arkansas and the upcoming Project Ponderosa in Arizona, the latter of which specifically utilizes forest-thinning material to reduce wildfire risks. In addition to mitigating 60,000 tons of emissions for JPMorganChase, the projects facilitate land restoration, create rural economic opportunities, and demonstrate a robust pathway for biomass-based carbon removal that is both scientifically sound and financially sustainable.
