Agraferm GmbH

Agraferm GmbH, based in Pfaffenhofen an der Ilm, Germany, is a turnkey provider of anaerobic digestion plants for biogas, biomethane (renewable natural gas), and waste recycling applications, with over 100 reference installations across approximately 20 countries. The company is one of the few providers offering both agricultural and industrially designed complete plants, distinguishing itself through its patented high-load fermentation technology that achieves high volumetric loading with minimal fermenter volume and correspondingly small plant footprint. This allows capacity upgrades from 500 kWel to 1.5 MWel on the same site footprint. Agraferm's core technology is the Paddle Mixer (Paddelrührwerk), which enables exceptional substrate flexibility — operators can process atypical feedstocks including grass, solid manure, chicken manure, straw, and food waste, and freely switch between substrate mixtures (e.g., from maize to slurry or green waste) without investing in new technology. The company's high-performance fermentation system minimizes process water recirculation, reducing fermenter volume requirements while maintaining retention time, which translates to lower capital costs and higher gas yields. Agraferm also offers biomethane upgrading systems (Biomethan-Aufbereitung) for producing pipeline-quality renewable natural gas, and waste treatment and preparation systems (Abfall-Aufbereitung) for processing organic waste streams through anaerobic digestion. The Metomex service brand provides biological process support and optimization. Agraferm's plants are designed for maximum reliability and minimized operating and maintenance costs, with quality construction that the company states is valued by both operators and project financiers.
