What Econvert does

Econvert Water & Energy B.V. is a Dutch industrial engineering company founded in 2012 and headquartered in Heerenveen, the Netherlands, specializing in anaerobic wastewater treatment and biogas desulphurization for industrial and municipal clients. The company operates as a Global Technology Center within Nijhuis Saur Industries (NSI), itself part of the Saur Group, and serves customers in Pulp & Paper, Food & Beverage, Chemical & Pharmaceutical, and Waste-to-Energy sectors, with a stated installed base of 200+ references across 36 countries. Named customers include Essity Cuijk, Nordzucker, Aviko Deutschland GmbH, and Stora Enso.

Econvert's product portfolio centers on six registered proprietary technology brands: Econvert-UASB® (Upflow Anaerobic Sludge Blanket), Econvert-EGSB® (Expanded Granular Sludge Bed), Econvert-IR® (Internal Recirculation), and Econvert-DGF® (Dissolved Gas Flotation) for anaerobic wastewater treatment, plus Econvert-Dsulph® and Econvert-RTF® (Regenerative Trickling Filter) for biogas desulphurization. The technology uses biological processes — anaerobic bacteria to break down COD/BOD without oxygen while producing biogas for heat and electricity, and sulfur-oxidizing bacteria to remove hydrogen sulfide from biogas. Supporting the core reactors is an accessories line (biogas buffers, flares, blowers/compressors, cooling/drying) plus an Anaerobic Rental option that allows clients to avoid upfront capital expenditure.

The business model is enterprise direct sales: project-based, quote-priced, multi-year contracts covering design, installation, and after-sales service including spare parts, consumables, and biomass supply. Revenue derives from one-time equipment sales, hardware, and recurring professional services. The company is led by Managing Director Ids Auke Boersma and operates with a stated workforce of more than 80 employees, distributed across the NSI regional network spanning Benelux, France, Central Europe, UK & Ireland, Central Asia, Americas, Middle East & Africa, and Asia Pacific.

• Aquatech International: Global water and wastewater solutions provider with industrial process water and wastewater reuse capabilities; increasingly active in anaerobic/biological treatment for F&B, pharma and energy customers, competing for the same project pipeline as Econvert.
• Ovivo (now Kurita Ovivo): Canadian-headquartered water and wastewater treatment specialist with industrial and municipal anaerobic treatment offerings; acquired by Kurita, providing scale and geographic reach comparable to Econvert's NSI-backed model.
• Xylem (Water Solutions): Global water technology major with industrial wastewater treatment and biological process offerings (e.g., Sanitaire, Wedeco, Evoqua). Competes with Econvert on biological treatment and biogas projects for industrial end markets.
• Ecolab (Water & Process Services): Industrial water and process management major (including Nalco Water) addressing wastewater, reuse and energy recovery needs across F&B, pulp & paper, chemicals and pharma. Overlaps with Econvert's industrial customer base and water reuse value proposition.

Emerging players

• Cambrian Innovation: US-based provider of industrial wastewater treatment and resource recovery (EcoVolt anaerobic/biomethane systems) for food & beverage and breweries. Comparable on anaerobic + biogas recovery proposition in industrial markets.
• WABAG / VA Tech Wabag: Indian-headquartered EPC contractor specializing in municipal and industrial water and wastewater treatment, including anaerobic and biogas recovery systems. Comparable in addressing high-COD industrial wastewater for F&B, pulp & paper and refinery customers.

Direct peers

• Paques (Paques Environmental Consultants): Dutch provider of anaerobic wastewater treatment (THIOPAQ, BIOPAQ) and biogas desulphurization technologies. Most direct competitor to Econvert's UASB/EGSB/Dsulph/RTF portfolio, serving the same pulp & paper, food & beverage and chemical customers globally.
• Biothane / Veolia Biothane Systems: Specialist in anaerobic (UASB/IC) industrial wastewater treatment; now part of Veolia Water Technologies. Directly competes with Econvert's UASB/EGSB/IR reactors for high-COD industrial wastewater customers.
