Erg Bio is a Dublin, California–based bioindustrial startup focused on biomass valorization for the production of synthetic aviation fuels and critical chemicals. Its core product, Aspire™, is a low-temperature pretreatment and catalytic system derived from research at Lawrence Berkeley National Laboratory’s Joint BioEnergy Institute. The technology can process more than 30 different biomass types, allowing flexible sourcing of agricultural and forestry residues that would otherwise be discarded. By turning these wastes into high-value intermediates, Erg Bio aims to enhance supply-chain resilience, support rural economies, and advance domestic energy security. The company plans to use newly raised capital to expand engineering and bioprocessing teams, validate the technology technically, and move toward pilot-scale demonstrations. To date, Erg Bio has secured $6.5 million in seed funding; no revenue or user metrics were disclosed in the article.
