£400k · Other round · Agritech · Harpenden, UK
Harpenden-based EcoNomad Solutions has raised £400k in blended funding to develop and deploy its small-scale anaerobic digestion systems. Tech.eu reports that British Design Fund contributed £230k, alongside an Innovate UK Investor Partnership grant and further support from existing investor Beeches Group. The company says the capital will fund product development and commercial deployment in the UK, followed by expansion into Europe.
Scaling anaerobic digestion down to farm level
EcoNomad is building BioNomad, a patented modular system designed to process manure and slurry on livestock farms that are too small for conventional industrial digesters. The company says the unit converts those wastes into biogas that can supply heat or electricity, while leaving nutrient-rich digestate for use as fertiliser. Its modular design is intended to let farms add capacity as their needs grow rather than commit to a large plant upfront.
That small-farm focus changes the commercial problem. EcoNomad is not trying to prove that anaerobic digestion works; it is trying to reduce the equipment, installation and operating burden enough for a smaller holding to adopt it. The company reported through British Design Fund that its systems are deployed on more than ten UK farms, with additional installations in Africa and trials across insect farming, food-waste streams and hybrid renewable systems. Those are company-reported deployments, not evidence yet of repeatable unit economics.
There is, however, independent evidence that the technology is operating in the intended setting. A 2026 Rothamsted Research study used digestate from a 15-cubic-metre EcoNomad reactor installed on a roughly 20-cow Lincolnshire dairy farm. The study examined the digestate as a wheat fertiliser; it does not validate EcoNomad’s commercial model, but it does show the system producing an agricultural output on a small farm.
Blended capital for the next product step
The financing combines £230k of BDF investment with grant funding and follow-on backing. That structure is useful for an early hardware company: non-dilutive capital can pay for engineering and field validation, while private investment supports the organisation needed to sell and service the product. EcoNomad says its next step is to make BioNomad more automated and plug-and-play before widening deployment.
Execution now depends on turning working installations into a repeatable product. Smaller farms may value lower energy and fertiliser bills, but adoption will also depend on installation effort, maintenance, reliability and payback under different herd sizes and operating patterns. The round gives EcoNomad room to simplify those variables; the commercial milestone will be whether farms can buy the system as standard equipment rather than treat every installation as a bespoke project.
