Charm Industrial captures carbon by turning agricultural residues into bio-oil through pyrolysis and then pumps the bio-oil deep underground where it solidifies, permanently storing CO2. This process uses agricultural waste as feedstock and creates a self-sustaining chemical reaction to convert biomass into a carbon-rich liquid, which is injected underground for long-term storage, reducing risks like wildfires, soil erosion, and land-use change. The company charges agricultural clients for converting their residues into bio-oil and storing it, offering end-to-end carbon capture and storage services. Unlike typical CCS firms that rely on industrial CO2 streams or dedicated geological projects, Charm Industrial focuses on readily available farm waste and provides a complete service from feedstock collection to underground sequestration. Its goal is to help customers cut their carbon footprints and contribute to lowering atmospheric CO2 levels over time.

Disclosure: AgFunderNews’ parent company is AgFunder. Agtech deals of 2023 followed much the same trajectory as other tech sectors, with lower valuations and far fewer mega-rounds than seen in the VC heyday of 2021 and early 2022. This year also saw a shift towards more investment in climate-focused solutions, hence the multiple waste-to-energy startups and carbon-related companies on the list below. Ag biotechnology, which includes the biologicals sector, was another strong category this year
In 2022, Charm collaborated with carbon management firm Carbon Direct and consulting firm EcoEngineers to publish a prototype protocol to help inform MRV standards for the type of carbon removal the startup performs, called bio-oil sequestration.
