BioFactory is working on a new way for farmers to make money from farm waste.

Somerset-based BioFactory are developing a modular anaerobic digester which can be scaled to any size of dairy farm. The company has been working with precision engineering and innovation experts Agri-EPI Centre, to develop and refine their system with a view to bringing it to the market.

Whereas anaerobic digesters – which ferment organic matter to produce biogas for heat and power generation – are well established in the industry, systems are often too costly and high-maintenance for most family farms.

Agri-EPI Centre have helped BioFactory access funding, provided technical assistance, and introduced them to potential funders and advice to help them scale their product and sell it to dairy producers.

Having won funding from Innovate UK and Defra for a 12-month feasibility study via the Farming Innovation Programme, BioFactory are now raising working capital to commercialise the company fully, while Agri-EPI Centre continue to provide analysis and consultancy.

Charlie Bowyer, business development manager for livestock and aquaculture at Agri-EPI Centre, said: “Slurry is nutrient-rich, and returning it to the soil is a vital part of circular agriculture. Anaerobic digestion is a great way to add value to it whilst retaining nutrients, reducing GHG emissions and becoming more energy-independent.

“Digestate has long been recognised as a high-quality fertiliser, and the heat and power created from biogas can create a meaningful income for farmers or reduce their energy bills. Commercial AD systems are simply out of reach for most dairy farms due to capital and operational costs, as well as barriers such as planning permission and a changed subsidy landscape since the “AD-boom” of the early 2010s.

“Working with young companies like BioFactory is Agri-EPI Centre’s bread and butter; helping them develop a good idea into a successful business and providing solutions to farmers at the same time.”

Jon Blake, chief commercial officer at BioFactory, said:

“If you’re a dairy farmer, you will always have slurry, but we can help turn it into an asset rather than a by-product. There is nothing to say that we can’t resolve farming’s impact on the environment as well. Our ethos is to build something simple and reliable for the dairy farmer. Our units are 40’-long shipping containers and easily scaled; if you want to increase your herd, you can simply add another reactor. “We were so lucky to be in the right place at the right time. Our young company had been waylaid by Covid-19 when we came across a pot of funding for developing technology to help with net zero targets. Agri EPI-Centre helped us get hold of our grant and develop our product in real-life farming conditions. “Even though the initial 12-month project has concluded, we are so pleased to continue our relationship with Charlie and his colleagues on laboratory analysis of the biodigestate, and with others at Agri-EPI Centre who are helping us with leveraging further funding and sales contracts.”
