What ZGM Zębiec does

ZGM Zębiec S.A. is a Poland-based, state-owned industrial manufacturer (founded 1954) operating three distinct business pillars from its integrated facility in Zębiec, Starachowice. Its boiler division manufactures solid-fuel central heating boilers — pellet (PERŁA, RUBIN, AGAT, DIAMENT), wood gasification (WENUS WOOD), coal batch-fired (WENUS ECO), and ecogroszek (KORAL) models — with power outputs from 10–24 kW, efficiencies up to 96.46%, and 5th class emissions / Ecodesign compliance. The boiler technology is patent-protected and incorporates automatic feeders, self-cleaning systems, and internet-connected controllers for remote management. The minerals division (operating as 'Zębiec Minerals' since 2017) produces bentonite, bentonite mixtures, resin-coated sands, slag coagulants, expanded perlite, and granulated bentonite for foundries, construction, agriculture, filtration, and environmental applications. The metal production division manufactures springs, leaf springs, agricultural machinery components, steel structures, and foundry templates.

The company monetizes through direct hardware sales to industrial customers, a nationwide authorized distributor network for residential boilers, regional sales advisors (north and south Poland), and an e-commerce platform for spare parts. Boiler pricing is quotation-based and disclosed via downloadable PDFs; mineral and metal products are custom-priced per specification. It holds ISO 9001, ISO 14001, and ISO 45001 certifications, Złoty Certyfikat Rzetelności KRD, and ZUM-list registration qualifying its products for the Polish 'Czyste Powietrze' subsidy program. The company is controlled by ARP S.A. (Polish Industrial Development Agency), which provided approximately 74.5 million PLN in capital support in 2026.
