KÜTTNER MARTIN Technology

What KÜTTNER MARTIN Technology does

KMT GmbH (KÜTTNER MARTIN Technology) is a Munich-headquartered engineering firm that plans and constructs turnkey plants for the thermal utilization of municipal sewage sludge, with integrated phosphorus recovery. The company operates as a subsidiary of MARTIN GmbH für Umwelt- und Energietechnik and runs a second office in Butzbach near Frankfurt. KMT employs more than 40 specialists with operational fluidized bed experience dating to the 1990s, anchored on its proprietary stationary fluidized bed furnace technology (KMT-Wirbelschichtofen) designed specifically for low-calorific fuels such as dewatered sewage sludge. The core platform combines the fluidized bed furnace with staged combustion air and afterburner chamber, multi-stage flue gas cleaning, heat recovery / steam generation, and a dust separation step that enables downstream phosphorus recovery from ash — features the company positions as compliant with German BImSchV emission limits and the post-2029 sewage sludge ordinance.

KMT's commercial offering spans four revenue streams: EPC contracts for complete turnkey sewage sludge utilization plants (Klärschlammverwertungsanlagen), supply of proprietary process technology and equipment, engineering and permitting consulting, and on-site commissioning (IBS) services. Pricing is project-specific with no public disclosure; contracts are won through competitive bidding and direct negotiation with municipal utilities, waste-to-energy operators, and industrial customers, with individual construction timelines of 30–36 months. The reference portfolio includes plants in Germany (Bitterfeld-Wolfen ~270 kt/yr, Berlin-Waßmannsdorf 3 lines × 3.4 t DM/hr, Stavenhagen ~160 kt/yr, Rothensee ~55 kt/yr, Erfurt 1.75 MW / 25 kt/yr) and the Netherlands (HVC Dordrecht heat recovery on a 380 kt/yr 4-line facility; Delfzijl). Technology partnerships within the MARTIN Group ecosystem and with suppliers such as LUEHR FILTER, LOIBL FÖRDERANLAGEN, and Würz GmbH support execution on combined incineration tenders where KMT handles the sewage sludge line and group partners handle municipal waste and balance-of-plant.

The go-to-market is enterprise field sales targeting a narrow buyer universe of municipalities, city utilities, and waste-to-energy operators. Marketing is limited to a LinkedIn presence, the company website, and career pages hosted by parent MARTIN GmbH; lead generation relies primarily on competitive infrastructure tenders and direct utility relationships. Customer concentration is high by name, with seven large multi-year EPC contracts visible in recent history driving the majority of revenue.

Core offering

KMT GmbH plans, engineers and constructs turnkey plants for the thermal treatment of municipal sewage sludge, built around its proprietary stationary KMT fluidized bed furnace. The plants enable near-energy-autonomous combustion of low-calorific sewage sludge without auxiliary fuel, recover phosphorus from the resulting ash, and feed generated heat into district heating networks and electricity generation. Offerings range from complete greenfield plants to integrated lines within existing waste-to-energy facilities, delivered on 30–36 month construction cycles.

Product overview

KMT GmbH provides industrial plant engineering for thermal sewage sludge utilization. The core product is the proprietary KMT-Wirbelschichtofen (KMT Fluidized Bed Furnace), which serves as the central technology component. KMT delivers complete sewage sludge utilization plants (Klärschlammverwertungsanlagen) as turnkey solutions, as well as individual components and partial plant systems. The offerings range from complete greenfield installations to brownfield integrations into existing waste-to-energy infrastructure, with each solution incorporating the fluidized bed furnace core combined with sludge drying, steam generation, and multi-stage flue gas cleaning systems.

Products and services

• KMT Stationary Fluidized Bed Furnace (KMT-Wirbelschichtofen) Proprietary stationary fluidized bed furnace designed for thermal utilization of low-calorific fuels such as sewage sludge, typically operating without additional fuel and featuring high plant availability, high automation, and staged combustion variants. Serves as the central combustion component of KMT sewage sludge utilization plants supplied to municipal utilities and waste-to-energy operators.
• Sewage Sludge Utilization Plants (Klärschlammverwertungsanlagen) Complete turnkey plants for thermal sewage sludge utilization with integrated phosphorus recovery, combining fluidized bed combustion, steam generation, multi-stage flue gas cleaning, and ash processing into a single delivered system. Supplied to municipal utilities (for example, Stadtwerke Erfurt) and to waste-to-energy operators (for example, EEW Stavenhagen, RWE Power Knapsacker, MHKW Rothensee), with reference capacities between roughly 25,000 and 380,000 tonnes per year of sludge.
• Engineering, Permitting and Consulting Services Standalone engineering, permitting planning, and technical consulting services for sewage sludge utilization facilities, including process engineering and integration into existing infrastructure. Sold independently to plant owners on a project basis (for example, the engineering support contracts awarded by WtE Wassertechnik in November 2020 and by RWE Power AG in December 2020).
• Installation, Commissioning and Heat Recovery Components Installation and commissioning (IBS) of KMT plants and supply of integrated heat recovery components (such as the exhaust steam heat recovery system delivered to HVC Dordrecht in October 2021). Includes on-site startup support, performance optimization, and condensate/Brüden handling subsystems that complement the fluidized bed furnace core.

Direct peers

• MARTIN GmbH für Umwelt- und Energietechnik: Parent company and direct technology peer; MARTIN designs and builds municipal waste incineration plants and is KMT's sister supplier within integrated MVA+KVA projects (e.g., Rothensee Block 3). Operates in the same DACH municipal thermal-waste market with adjacent fluidized bed expertise.
• Andritz AG: Global supplier of sludge treatment and thermal drying/incineration systems, including fluidized bed technology for sewage sludge. Competes head-to-head with KMT for municipal sewage sludge utilization projects across Europe.
• Steinmüller Babcock Environment (Bilfinger): German-rooted EPC firm specializing in thermal waste and sewage sludge incineration plants using circulating fluidized bed technology. Direct competitor in DACH municipal sludge incineration tenders.
• Metso Corporation: Supplies fluidized bed combustion and heat recovery systems for industrial and waste-to-energy applications. Overlaps with KMT's fluidized bed furnace technology offering, including for low-calorific fuels and biomass-derived sludges.

Broad incumbents

• Hitachi Zosen Inova (HZI): One of the world's largest waste-to-energy EPC firms, with capabilities spanning grate and fluidized bed combustion, flue gas cleaning, and energy recovery. Competes broadly with KMT where municipal customers seek integrated waste-and-sludge packages.
• RWE Power AG: Major energy utility and one of KMT's largest customers (Knapsacker Hügel, 2x 180,000 t/year lines). RWE operates significant waste-to-energy and biomass generation assets and could vertically integrate thermal sludge capabilities.
• EEW Energy from Waste: One of Europe's largest waste-to-energy operators and a KMT customer (Stavenhagen mono-sewage sludge plant). EEW's operational scale across Germany creates both EPC demand for KMT and a potential competitive threat if it internalizes sludge incineration capabilities.
• Suez Recycling and Recovery GmbH (SUEZ): Global environmental services and wastewater treatment major with growing involvement in sewage sludge valorization and thermal treatment in Europe. Competes indirectly via integrated sludge-management offerings to municipalities.
• Veolia Environnement: Global water and waste services major; operates municipal wastewater and sludge treatment assets across Europe, including thermal sludge solutions. Competes with KMT for municipal infrastructure contracts and could substitute with in-house offerings.

Regional players

• CNIM Groupe (Constructions Industrielles de la Méditerranée): French-rooted EPC firm with strong waste-to-energy and fluidized bed capabilities, active primarily in France and select international markets. Comparable in technology stack to KMT and competes for European municipal sludge incineration contracts.
