Purac

What Purac does

Purac AB is a privately held Swedish environmental technology company founded in 1956 in Lund and originally established as part of Tetra Pak. The company designs, builds, and commissions turnkey plants for drinking water treatment, municipal and industrial wastewater treatment, and biogas production, with a wholly-owned subsidiary (Purac Lanka Pvt Ltd) supporting limited international work and a Norwegian project footprint led from its Swedish base. The technology stack spans conventional processes (DAF, rapid sand filtration, lamella sedimentation) and advanced biological and membrane processes (IFAS, MBBR, SBR, ultrafiltration with 20nm pore size achieving 4-log virus / 6-log parasite reduction, and HFNF membranes), wrapped around two proprietary process packages — Purac EWA™ for food-waste pretreatment and Purac ReNu™ for converting digestate into KRAV-certified pelleted biofertilizer. Equipment partnerships with membrane suppliers (notably Pentair X-Flow) and construction partners (PEAB, Skanska, NCC, AF Bygg Syd) are used to deliver projects, with Purac retaining process design, plant design, installation, and commissioning in-house.

Purac generates the majority of revenue through large, project-based infrastructure contracts — Gräfsåsen Biogas Östersund at SEK 230 million and Arvidstorp at roughly SEK 132 million are representative — awarded via Swedish/Norwegian public procurement and structured as partnering, fixed-price, cost-plus, or full turnkey engagements. Customers are primarily Swedish and Norwegian municipal utilities (Trollhättan Energi, Ystad kommun, Östersunds kommun, Gnesta kommun, Skaraborgsvatten, Mariestads kommun, Trelleborgs kommun, Göteborgs stad, Stockholm Vatten och Avfall, LEVA i Lysekil, SÅAB, Kumla kommun), supplemented by an industrial and waste-management segment (Biond Production AB, Alviksgården Lantbruks AB, Greve Biogass AS with partners Lindum and Vesar). A service and after-sales organization (frame agreements, quarterly visits, well inspection and renovation) provides a smaller recurring revenue stream over the installed base of 5,000+ completed projects.

The company employs approximately 130 people, reports annual revenue in the SEK 600-800 million range, and is led by CEO Mats Helander with a senior team covering technology (Daniel Ling), HR (Anita Asklund), finance (Rose-Marie Reimer), regional operations, large projects, sales and marketing, HSSEQ, and procurement. Purac holds no external funding, no disclosed parent company, and has emphasized organic growth, employer branding (Karriärföretag 2026), and long-term partnering relationships as its core commercial strategy across its five Swedish regional offices plus the Sri Lanka subsidiary.

Revenue model

1. Infrastructure Project Contracts (Design, Build, Commission): Purac generates the majority of revenue through large infrastructure project contracts for municipal and industrial clients. These encompass the full project lifecycle from early process studies and design through construction, installation, and commissioning of water treatment, wastewater treatment, and biogas plants. Projects are typically awarded via public procurement or partnering arrangements. Revenue recognition is project-based, with contract values ranging from tens of millions to hundreds of millions of SEK per project.
2. Service, Maintenance and After-Sales: Purac provides ongoing service, maintenance, process optimization, and modernization of existing plants throughout their operational lifetime. The company has a well-established service organization and offers service agreements (e.g., quarterly visits) and frame agreements for operational support. This generates recurring revenue from existing installed base.
3. Process Equipment and Technology Supply: Supply of proprietary process equipment and technology systems (e.g., Purac EWA™, Purac ReNu™, ultrafiltration membranes) as part of total turnkey contracts or as standalone equipment supply. Includes spare parts supply and upgrades.
4. Drinking Water Well Service: Purac offers well/drilling services including inspection, renovation, high-pressure cleaning, acid treatment, capacity testing, and camera inspection for drinking water wells. This is a service stream targeting both municipal and private water supply customers.
