Comef

What Comef does

Comef s.r.l. is a privately held Italian industrial engineering and construction company founded in 1968 in Milan and headquartered in Tradate (Varese), operating from a 68,000 m² integrated facility that combines three production workshops, warehousing, and multi-disciplinary engineering functions. The company designs, fabricates, assembles, and services waste-to-energy (WtE) plants, biomass energy plants, industrial boilers (water-tube and fire-tube), cogeneration plants, and district heating systems, primarily for municipal utilities, waste management operators, and industrial customers. Proprietary capabilities include Inconel cladding of steam generator internals, complete flue gas treatment systems (including SCR for NOx control), grate and fluidized-bed furnaces, and full EPC project delivery as general contractor.

The business operates on a project-based revenue model built around four streams: turnkey EPC plant contracts, equipment and parts supply, after-sales services (preventive maintenance, modernization, training, spare parts), and — more recently — external Inconel cladding services offered to OEMs, refineries, and petrochemical operators. Pricing is quote-based and project-specific rather than standardized. Go-to-market is direct enterprise sales through regional representatives covering Italy, Europe, and International markets, supported by multilingual digital presence, industry publication features, and event-driven demand generation. Customer logos include NEUTALIA, ACEA, A2A, A.V.A., Accam, ACSM-AGAM, B.E.A., Calce (for Sydetom 66), and Termomeccanica across Italy, France, Portugal, and Poland.

Certifications (UNI EN ISO 9001, 14001, 45001, 3834 Part 2, EN 1090-1, and Italian public works qualifications OG9/OS14/OS16) underpin qualification for European municipal tenders, and the company's stated base of over 100 installed plants since 1968 functions as a reference asset for new project capture. The firm employs 51–100 people, is privately held with no disclosed parent, no funding rounds, and no public listing, and recent 2026 activity shows active engagement on multiple concurrent WtE and cogeneration projects alongside capacity expansion (Industry 5.0 milling machine) and service-line diversification (external Inconel cladding).
