What fm bioenergy does

FM BioEnergy is a UK-based specialist provider of biological and chemical additives, silage inoculants, and biological support services for anaerobic digestion (AD) plants. It operates as a branded business unit of CirQlar UK, itself part of the ForFarmers Group, with headquarters at Bury St Edmunds and a coverage claim that its client base generates over 35% of UK AD biogas output. The company serves both agricultural AD operators (crop-based feedstocks such as grass and wholecrop cereals) and waste AD operators (food waste, chicken litter), with products spanning trace element supplements (BC.MICROcon5 daily-dose tab, bespoke BC.PRO/BC.MAGXX/CR.TEplex formulations), H2S and ammonia control (ATOX.Scon, ATOX.Ncon), enzymes (BC.Zym), and silage inoculants (Silasil Energy SG and XD, with XD holding DLG approval for increased methane yield). Technical differentiation is anchored in a partnership with Schaumann BioEnergy, the German market leader in biogas optimisation, which supplies formulations and German laboratory support.

The company runs a sales-led B2B model with field-based specialists offering free digester health checks as a lead-generation mechanism, supported by direct phone/email sales, rapid-delivery stock of additives, and a content marketing program via its CirQlar UK website (Knowledge Hub, case studies, weekly commodity reports). Revenue is generated across four streams: digester additive sales, silage additive sales, recurring biological support contracts (3–12 months), and Leak Detection and Repair (LDAR) surveys using the EyeCGas 2.0 optical gas imaging camera (ADCS-accredited). The company has completed over 1,000 LDAR surveys across UK and Germany, finding that 85% of surveyed plants exhibit biogas leakage. Customer references include Vale Green Energy, BioWatt, Generation X, Icknield Gas, Boxford Suffolk Farms, Springvale Energy, Ener-G BIO, and Willsborough AD.

Operationally the unit is small and tightly specialised: the named UK team includes a General Manager, a National Biogas Silage Specialist with 35 years of agronomy experience, an Account Manager with a PhD in anaerobic digestion, a Biogas Leak Detection Service Lead (15+ years AD plant operation, certified OGI camera operator), and a Business Development Manager AD hired in December 2025. FM BioEnergy does not disclose standalone revenue and operates as a privately held subsidiary of the Dutch agricultural group ForFarmers, with no external funding rounds.
