What Compost Systems GmbH does

Compost Systems GmbH is an Austrian engineering firm headquartered in Wels, Upper Austria, that designs and delivers biological waste treatment systems for municipal, industrial, and agricultural composting operators worldwide. The company's product portfolio spans systems technology (COMPOair aeration fans, COMPOtainer plug-and-play fan stations, concrete aeration pipes, exhaust air conditioning with biofilters achieving 90–98% odor reduction, box roofs, and hydraulic door systems), machine technology (the CMC ST tractor-drawn compost turner line — ST 200, ST 230, ST 300, ST 350 — plus the TracTurn, self-propelled CMC SF 200 and SF 300 turners, AELUS air separator removing up to 95% of plastic contaminants, drum screening stations, mixer/bag openers, and trench cleaners), container technology (CSC-Container with integrated GPS tracking and Earth Flow automated pre-rotting system), measurement and control technology (EMSR with VISU visualization and a cloud platform for remote monitoring), and compost covers. All CMC-branded turners comply with the company's proprietary Controlled Microbial Composting methodology developed from 50 years of family-rooted research originating in 1971.

The company sells through a B2B enterprise field sales motion, delivering project-based quotations that combine hardware, custom EMSR/ICA control engineering, and full-service engineering and consulting (concept development, operator training, plant monitoring, R&D, permits, feasibility studies, planning, and quality assurance). It reaches customers via 10+ country representatives across Western, Central, and Eastern Europe, CIS, Iberia, Latin America (Chile, Brazil), Serbia/SEE, Bulgaria, and Northwest Africa, supported by a 9-language website, major industry trade shows (Ecomondo, EuroTier, Carrefour des Déchets, Austrian Compost Congress), and the annual International Compost Seminar held in Wels. Primary customer segments are waste treatment operators, with secondary segments in agricultural operations and municipal governments; the firm has delivered 250+ reference plants globally since founding in 2002 by CEO Aurel Lübke, who leads a team of 17 employees.

Emerging players

• HCL Machine Works: US manufacturer of compost turners and screening equipment serving smaller-scale composting operators — comparable product line with a more regional/niche focus.
• Midwest Bio Systems: US firm specializing in composting equipment and microbial inoculants with a comparable focus on controlled microbial composting processes (similar in concept to the CMC method).

Direct peers

• MENART: French/Belgian manufacturer specializing in composting and shredding equipment, offering turners and screening solutions to a similar municipal and agricultural operator customer base.
• Eggersmann Anlagenbau: German engineering firm designing and building composting and MBT (mechanical-biological treatment) facilities with comparable engineering-led sales motion and municipal customer base across Europe.
• SCARAB International: US-based manufacturer of compost turners and windrow equipment, comparable in product offering (tractor-pulled and self-propelled turners) and serving similar municipal/industrial composting customers.
• Komptech GmbH: Austria-headquartered manufacturer of composting and waste treatment machinery (turners, shredders, screeners). Closest direct competitor to Compost Systems with overlapping product categories, target customers (municipalities, waste operators), and European geographic footprint.
• BACKHUS GmbH: German manufacturer of tractor-pulled and self-propelled compost turners, directly competing with Compost Systems' CMC ST and CMC SF product lines in the global composting equipment market.
• Engineered Compost Systems: US-based engineering consultancy designing composting facilities with equipment integration — directly comparable business model as a specialized composting engineering and equipment firm.

Broad incumbents

• Jenz GmbH: German manufacturer of wood and green waste processing machinery (shredders, chippers), serving an overlapping customer base of composting operators with broader biomass equipment offerings.
• Terex Ecotec: Global industrial machinery brand (Terex) offering shredders, screeners, and material processing equipment used in composting and waste operations — overlapping customer base but broader industrial focus.
