Malmberg

What Malmberg does

Malmberg is a fifth-generation, family-owned Swedish cleantech company founded in 1866 and headquartered in Yngsjö, operating in water, wastewater, biogas, geothermal energy, and industrial drilling. Its core technology platforms are the COMPACT™ water-scrubber biogas upgrading system (with the GR 20 capable of upgrading 2,400 Nm³/h to biomethane), the AQUAERA™ flexible upgrading family spanning FREJA to ODEN models with digital monitoring and 24/7 support, the GRM membrane biogas upgrading plants (GRM25/GRM50) delivering ≥99.8% methane recovery at ~0.26 kWh/Nm³, the EnerGeo® geoenergy (heat-pump and borehole) system, and MABR wastewater treatment using Veolia's ZeeLung® membrane. The group also designs and manufactures prefabricated energy centers, tanks, and process equipment under its Malmberg Industrial Design unit.

The business is organized into three operating pillars: Malmberg Borrning AB (drilling for water supply and geoenergy), Malmberg Energy AB (biogas upgrading, geoenergy, service & support, and production), and — until September 2024 — Malmberg Water AB (water and wastewater treatment), which was divested to ELIQUO WATER GROUP while the family retained Energy and Borrning. Revenue model is project-based and B2B: large municipal and industrial infrastructure contracts typically valued at 90–200+ MSEK, won through competitive tenders or direct negotiation, with delivery spanning multi-year cycles; complementing revenue comes from equipment sales of proprietary upgrading/membrane/heat-pump units and ongoing service & 24/7 support contracts. Reported 2023 revenue was 761 MSEK (~$76M) with ~170 employees, and the group has recorded over 1 billion SEK in order intake for two consecutive years.

Malmberg serves municipal water utilities (Stockholm Vatten, VA SYD, Kristianstad, Jönköping), biogas plant operators (Den Magiske Fabrikken, Envidan, Bigadan, Bioenergie St. Lorenzen, Bio-Kusenhof), property/real-estate companies (Vasakronan, Akademiska Hus), industrial clients (Volvo Cars, IKEA, DHL), and agricultural cooperatives, with operational presence across Sweden, Germany (regional HQ in Zwenkau), Denmark, Norway, Italy, and the UK. Go-to-market combines direct enterprise field sales, strategic technology partnerships (Grundfos, Veolia, Axiom), and an 'samverkan' integrated-delivery model from first concept through installation and ongoing service.
