Erg Bio

What Erg Bio does

Erg Bio is a U.S.-based biomanufacturing company founded in 2023 and headquartered in Dublin, California, that develops and commercializes a proprietary biomass-to-products platform branded as Aspire™ Technology. The technology is a low-temperature solvent pretreatment and catalytic conversion system — exclusively licensed from Lawrence Berkeley National Laboratory's Joint BioEnergy Institute — that processes over 40 types of non-food biomass, including agricultural residues, forestry waste, municipal solid waste, dedicated energy crops, and mixed feedstocks, into fermentable sugars, intermediates, and drop-in fuels. Key technical claims include 90-95% sugar recovery (versus 75-80% for traditional methods), >98-99% solvent recycling, compatibility with commercially available industrial equipment, a proprietary engineered yeast that consolidates cellulase/hemicellulase production and sugar fermentation into a single step, and preservation of high-quality lignin for downstream valorization.

The intended end products are synthetic aviation fuels (SAF), bio-based chemicals, bioplastics, and lignin-derived materials. The business model is B2B enterprise technology licensing combined with future managed-services revenue from integrated biomanufacturing facilities and direct sales of biochemicals/intermediates. The go-to-market combines direct enterprise sales to major fuel and chemical companies with a parallel government-channel strategy targeting the U.S. Department of Defense Distributed Bioindustrial Manufacturing Program (DBIMP) and Department of Energy/EPA Inflation Reduction Act funding programs. The company has secured non-dilutive government awards — including a DoD DBIMP award (announced September 2024 as one of 12 awardees totaling $42M) and a $6M DOE/EPA IRA grant (January 2025) — and closed a $6.5 million seed round in November 2025 led by Azolla Ventures with participation from Chevron Technology Ventures, Freeflow, Plug and Play, and strategic angel investors. As of the available data, Erg Bio operates with a team of approximately 12, is pre-revenue, and is positioned at the pre-pilot demonstration stage of its commercialization roadmap.

Core offering

Erg Bio develops and licenses Aspire™ Technology, a proprietary low-temperature solvent pretreatment and catalytic platform that converts non-food biomass (agricultural residues, forestry waste, municipal solid waste) into fermentable sugars, high-value intermediates, and drop-in fuels such as synthetic aviation fuel and bio-based chemicals. The company monetizes through technology licensing to industrial partners and is positioned to deploy integrated biomanufacturing facilities producing fuels and chemicals at scale.

Product overview

Erg Bio offers a single unified product platform called Aspire™ Technology, a proprietary low-temperature solvent pretreatment and bioprocessing system that converts waste biomass into fermentable sugars and intermediates for synthetic aviation fuels and critical chemicals. The technology includes an advanced distillable solvent system that recycles over 99% of its components, combined with proprietary engineered yeast that hydrolyzes and ferments sugars, closing the loop from feedstock to finished product.
