Consentis

What Consentis does

Consentis Anlagenbau GmbH is a German full-service provider for biogas plants, founded in 2001 and headquartered in Wietmarschen, Lower Saxony. The company is a wholly-owned subsidiary of the Bollmer Unternehmensgruppe, which also operates in agricultural fertilization concepts and bioenergy production, providing Consentis with cross-referral access and shared infrastructure within the German agricultural/energy nexus. Consentis delivers the complete lifecycle of biogas infrastructure — concept development, planning, permitting, construction, modernization, and ongoing maintenance — for livestock farmers (small-scale manure-based plants) and commercial biogas plant operators (large-scale, multi-CHP, post-EEG plants).

The technology stack centers on anaerobic digestion systems fed by manure, agricultural residues, and energy crops, combined with combined heat and power (CHP/BHKW) units supplied by OEMs such as MAN, Liebherr, and Jenbacher. Distinct technical capabilities include flexibilization retrofits (additional CHP capacity, gas/heat storage, smart controls), Organic Rankine Cycle (ORC) re-powering to convert waste heat into additional electricity, decentralized biogas upgrading to biomethane and Bio-LNG, district heating network construction, and Selective Catalytic Reduction (SCR) catalyst installation for NOx compliance under 44th BImSchV. Maintenance and rehabilitation services are delivered manufacturer-independently across all plant builders.

The business model combines project-based one-time revenue (new plant construction, modernization, repowering, tank storage, permitting) with a recurring service layer (BHKW maintenance, regulatory compliance inspections, rehabilitation, remote monitoring). GTM is sales-led and direct, relying on field consultation, the company website, project references, and Bollmer Group cross-referrals. Customer concentration is moderate across a disclosed set of named German agricultural and municipal biogas operators, with the business operating exclusively in a single country and a single regulatory environment (German EEG / post-EEG agricultural biogas). No external funding has been raised; ownership remains entirely within the Bollmer Group, managed by Geschäftsführer Georg Bollmer and Alexey Tsutskikh.
