AgriGrub

What AgriGrub does

AgriGrub Ltd is a UK-based circular-economy agritech company founded in 2018 and headquartered in Wisbech, Cambridgeshire, that farms Black Soldier Fly Larvae (BSFL) on food waste diverted from supermarket supply chains. The larvae, marketed under the brand "Calci Worms", are processed into four commercial products: live and dried larvae sold as high-protein, high-calcium feed for poultry, reptiles, hedgehogs and wild birds; defatted BSFL insect meal sold as a sustainable protein replacement for soy in fish feed and pet food; and BSFL frass, an OF&G-certified organic fertilizer with a slow-release N-P-K profile marketed to organic growers and conventional farmers. The underlying technology is a proprietary rearing process that converts food waste — which would otherwise go to landfill or anaerobic digestion and generate methane — into animal feed inputs and organic fertilizer, avoiding synthetic fertilizer use and supporting soil carbon sequestration.

The company operates with 1–10 employees and runs a direct-to-consumer and direct-to-business go-to-market via its own e-commerce site (agrigrub.co.uk), using specialized next-day fragile courier delivery for live larvae and pallet or standard courier shipping for dried, meal and frass products to commercial buyers. Beyond physical products, AgriGrub sells consultancy and IP licensing services to UK waste producers and other BSF producers seeking to handle diverse organic waste streams. The company is funded by UK innovation bodies WRAP, Innovate UK (IUK) and UKRI, with additional support from the GCGP Growth Hub, and holds OF&G organic certification for its frass. Public impact data indicates 1,516 tonnes of CO2 emissions reduced in the most recent reporting year and a 2030 scaling ambition to divert 85,000 tonnes of food waste annually.
