What Siloxa Engineering does
SILOXA Engineering AG is a German, family-owned specialist in gas purification, conditioning and drying for biogenic gases — biogas, sewage gas (Klärgas) and landfill gas (Deponiegas). Founded in 1998 and headquartered in Essen, the company designs and manufactures activated-carbon adsorption systems, gas dryers and complementary conditioning equipment, anchored by two core platforms: FAKA, a fixed activated-carbon adsorber offered in a pioneering dual-chamber (K2) configuration since 2003, and MAKA, a mobile plug-in/out adsorber available in three sizes for nominal flows from 40 to 650 m³/h. SILOXA also operates a proprietary ISDAC® activated-carbon production method that preserves full H2S adsorption capacity, and an adjacent line of iron-hydroxide consumables (FERROXA, FERROXA PLUS, FEPS) for H2S removal. Its product offering is sold alongside high-performance activated carbon variants (ACO DUO, ACO IMP, ACO S, ACO SI, ACO SIRP) and a comprehensive service package covering consultation, delivery, carbon exchange, disposal and maintenance.
The company monetizes through three streams: one-time equipment sales (turnkey FAKA/MAKA/GRW/Power Dryer/ADTR systems), recurring consumables (proprietary activated carbon and iron-hydroxide products with optional reactivation services via partners), and professional services for installation, commissioning and maintenance of both SILOXA and third-party systems. Pricing is quote-based, with structured payment milestones for installation projects (30%/60%/10%) and standard-delivery terms below and above a EUR 15,000 threshold. Go-to-market is sales-led with consultative selling to farmers, technical operators/OEMs, engineering firms, public organizations and distributors, executed through a direct channel anchored by the Essen HQ, regional offices in France (La Chapelle Saint Luc) and Italy (Grezzana), and an international distributor network. SILOXA supports its distribution with a multi-language website, LinkedIn/Facebook presence, a knowledge center/FAQ, and trade-fair participation such as IFAT 2026 in Munich, while partnering with greentech.ruhr on environmental-technology initiatives in the Ruhr region.

Siloxa Engineering competitors and assessment
Company assessmentDirect peers
- Haase Energietechnik GmbH: Haase Energietechnik manufactures gas cleaning and conditioning systems for biogas, sewage gas, and landfill gas, including absorption, scrubber, and activated carbon-based cleaning equipment. Directly comparable to SILOXA's FAKA, MAKA, and gas conditioning portfolio with a similar European municipal/industrial customer profile.
- Mahler AGS GmbH: Mahler AGS supplies activated carbon adsorption systems and related gas treatment solutions for industrial and biogas applications across Europe. Overlaps with SILOXA's activated carbon cleaning technology and consumable business, addressing the same H2S and contaminant removal use cases.
- CarboTech (Jacobi Carbons): CarboTech is a major European producer of activated carbons used in biogas upgrading, drinking water, and industrial air/gas purification. Overlaps with SILOXA's activated carbon consumable business, supplying many of the same operators and competing on carbon grade and service quality.
Broad incumbents
- Hitachi Zosen Inova (HZI): HZI delivers EPC and plant technology for biomethane upgrading, landfill gas, and sewage gas projects globally. A broader incumbent that competes at the project level; would specify or bundle gas conditioning subsystems in ways that can include or exclude SILOXA's adsorption solutions.
- Greenlane Renewables: Greenlane supplies water scrubbing, membrane, and PSA biogas upgrading systems under the GREENLANE name. Represents the membrane/PSA competitive route for RNG production that competes for the same European gas-cleaning specification dollars as SILOXA's activated carbon chain.
- Bright Biomethane (Bright Renewables): Bright Biomethane provides turnkey biogas upgrading systems (membrane, PSA, in-line methanation) used by operators across Europe. Competes with SILOXA upstream by packaging or displacing standalone gas conditioning equipment in EPC projects.
- Donaldson Company, Inc. Donaldson is a global industrial filtration and gas purification equipment manufacturer with broad product lines including compressed air and gas filtration. Operates in adjacent gas-cleaning categories with greater scale and geographic reach than SILOXA.
- Pentair (Gas Filtration & Separation): Pentair offers industrial gas filtration, separation, and purification technologies serving environmental and process industries. Represents a larger diversified filtration incumbent competing for the same specification opportunities in biogas/sewage gas plants.
- Dürr AG (Environmental & Energy Technology): Dürr AG operates an environmental technology business serving biogas cleaning, denox, and exhaust applications for industrial and waste-to-energy customers. A broader incumbent with deeper engineering resources and a wider regional footprint than SILOXA.
Emerging players
- RVT Process Equipment GmbH: RVT designs and supplies process equipment including gas cleaning, drying, and adsorption systems for environmental and chemical applications. A smaller European competitor in gas conditioning technology, overlapping with SILOXA in drying (ADTR/Power Dryer) and adsorption offerings.
