Citrimer

Green chemicals
without a green premium.

Citrimer produces sustainable, carbon-negative chemicals that perform better and cost less than dirty petrochemicals.

Our Products How It Works

Cost Advantaged Priced below conventional
petrochemical resin market rates

Sustainable High biobased content from
domestic agricultural feedstocks

Domestic Feedstocks sourced and resins
manufactured in the USA

Drop-in Performance-matched for existing
composite manufacturing lines

What We Do

Thermoset resins for a decarbonized world.

Citrimer produces green thermoset resins for composites manufacturing. Composites are used when material performance matters: automotive panels, boat hulls, sporting equipment, industrial structures, aerospace and defense components. We source feedstocks domestically, manufacture in the United States, and deliver the same performance as petrochemical resins at a meaningfully lower price and a fraction of the carbon footprint.

How It Works

The chemicals supply chain, reimagined.

We convert cheap, commercially available biobased feedstocks into high-performance resins using industry-standard chemistry and existing equipment.

Biobased Feedstocks

Cheap, commercially available agricultural inputs replace petroleum as the chemical building block. Sourced domestically, priced competitively.

Citrimer's Process

Proprietary thermochemical methods using industry-standard reactors. No novel infrastructure required — manufacturers adopt our resins without retooling.

Green Specialty Chemicals

High-performance resins that drop into existing composite manufacturing workflows at a lower price — and a dramatically lower carbon footprint.

About Us

Expertise at the molecular level.

We envision a world where petroleum is no longer the basis for chemicals and downstream physical goods. We select biobased feedstocks based on scalability and cost, so our products win on economics, not just sustainability.
