What Container does

Container d.o.o. is a Slovenian specialty industrial manufacturer founded in 1998 that designs and produces custom-engineered steel containers for transport, energy, ecological, and defence applications. The company operates from a 13,200 m² indoor and 1,500 m² outdoor manufacturing facility in Celje, Slovenia, with approximately 120 highly qualified employees producing around 1,400 containers annually. Its portfolio spans four core programmes: Transport containers optimized for combined road-rail freight (developed jointly with Innofreight GmbH, Montan GmbH, and Bruhn GmbH); Energy containers including modular battery storage systems developed in partnership with RWE under the Tricera brand; Ecological containers sold under its proprietary Atom trademark for low and medium radioactive waste handling, compliant with IAEA IP-2, IP-3, and Type A standards (Rina S.p.A. as a customer); and Safety containers for military equipment and personnel transport.

The company positions itself as a niche specialty manufacturer rather than a commodity producer. Its technical stack includes an in-house development and construction department using computer simulations for design optimization, certified welding capabilities (SIST EN ISO 3834, SIST EN 15085/2 CL1, DNV-GL, AQAP 2110 NATO), and an internal testing facility performing static, dynamic, gas tightness, drop, and functional testing per CSC, UIC regulations, and ISO 1496 standards. The revenue model is bespoke project-based manufacturing priced per project (pricing not publicly disclosed), supported by dedicated sales offices in Germany (Detlef Mügge, Arne Osenberg) and Switzerland (via Forstlogistik).

Container serves enterprise customers across four regulated verticals: nuclear waste handling, transport/logistics, energy systems, and defence. It maintains four ISO management systems (9001, 14001, 45001, 50001), holds the Atom trademark, and has received the Styrian Economic Excellence Award (2023), an EcoVadis Bronze Medal (2024), and two Gold Innovation Awards from the Slovenian Chamber of Commerce (2016 for Innotank, 2023 for Tricera/RWE). The company's June 2025 entry into the Slovenian Defence Industry Cluster (GOIS) signals an active push into defence market access, complementing its existing Safety programme.

Core offering

Container d.o.o. designs, develops, manufactures, and tests custom special steel containers for four programmes: transport (road/rail containers such as MOCO-Montan), energy (control centres for complex energy systems), ecological (Atom brand transport and storage of low and medium radioactive waste to IAEA IP-2/IP-3/Type A), and safety (containers for military equipment and personnel). All products are engineered, welded, and validated in-house at the Celje facility, with an internal test room enabling CSC, UIC, and ISO 1496 testing plus complementary steel constructions and testing services.

Product overview

Container d.o.o. is an industrial container manufacturer offering a portfolio of specialized products across four core programs: Transport containers (focused on weight optimization and durability), Energy containers/control centers (for energy management systems), Ecological containers under the Atom brand (for nuclear/radioactive waste transport and storage), and Safety containers (for military equipment protection). The company also manufactures steel constructions and provides in-house testing services. Production takes place in a 13,200 m² indoor facility with approximately 120 employees producing around 1,400 containers annually. The product range evolved from standard models to increasingly demanding special containers, supported by an in-house development department and technologically advanced production capabilities.

Products and services

• Transport Containers Specialized transport containers designed for low weight, high durability, and long lifetime, developed using computer simulations. The range includes the MOCO-Montan Container for combined road-railway transport, used by customers such as Montan GmbH and Innofreight.
• Energy Containers / Control Centres Containerized control centres for complex energy systems and manipulation of offshore platforms, addressing energy management and efficient solutions for energy problems.
• Ecological Containers (Atom Brand) Containers for transport and storage of low and medium radioactive waste under the company's own Atom trademark, including IP-2, IP-3, and Type A containers per IAEA standards. Container d.o.o. is positioned as the only manufacturer in Europe able to supply these classes.
• Safety Containers (Military) Containers designed for transport and protection of military equipment and personnel, developed within the safety programme and supported by AQAP 2110 NATO quality assurance and membership in the Slovenian Defence Industry Cluster (GOIS).
• In-house Container Testing Services In-house testing services including static and dynamic container testing, material hardness testing, dimension control, gas tightness testing, container disassembly testing, drop testing, and functional testing per CSC, UIC, and ISO 1496 standards, delivered through the ContainerLab advanced transparent testing project.
• Steel Constructions Steel constructions manufactured as part of the company's production programme, complementing container manufacturing under EN 1090 execution of steel structures certification.
