What Ahidra does
Ahidra, agua y energía, S.L. is a Spanish environmental engineering firm founded in 1998 and headquartered in Polinyá, Barcelona, that designs and delivers turnkey ("llave en mano") industrial wastewater treatment, organic waste valorization, biogas/biomethane, and industrial gas treatment plants. Since 2018 it has operated as "Ahidra Colsen Technologies" within the Netherlands-based Colsen Group, holding exclusive rights to deploy Colsen's proprietary biological and membrane technology portfolio in Spain and Portugal, including NAS® anammox-based nitrogen removal, AMFER® ammonia recovery, ANPHOS® phosphate recovery as struvite, BIDOX® biological biogas desulfurization, DIGESTMIX® digester mixing/heating, Poul-AR® poultry manure valorization, UASB anaerobic reactors, N/DN+MBR systems, and reverse osmosis.
The company executes projects under EPC contracting for industrial and municipal clients across Spain, Portugal, France, and Argentina, with a customer roster spanning food and beverage (Grífols, Danone, Casa Tarradellas, Bon Àrea, Miquel y Costas, Tereos, Friselva, Liquats Vegetals, Rousselot), pet food (SPF Symrise), energy and waste management (Prezero, EDF, ACCIONA, URBASER, Verdalia, TIRME, SAMCA, ERSUC), municipal infrastructure (NILSA), and agribusiness (Resal, BIOGASTUR). Revenue is generated through one-time EPC project fees, ongoing O&M service contracts, and technical consulting, with pricing project-specific and not publicly disclosed.

Ahidra partnerships and signals
Strategic signalPartnerships
Six partnerships are on record, tiered core, minor and flagship.
- Bioenergy Cluster of CataloniacoreAhidra participates in collaborative R&D projects with the Bioenergy Cluster of Catalonia, including an ACCIO-funded research project (2024) to study enzyme-enhanced methanization of organic waste with Liquats Vegetals. The cluster also organized joint webinars such as the Beauty Sustainability Week where Ahidra presented UASB technology.
- Liquats VegetalscoreCollaborates with Ahidra on the ACCIO-funded R&D project studying the methanization potential of agricultural and industrial organic waste pretreated with enzymes to enhance biogas production. Also a customer of Ahidra's UASB wastewater treatment plant.
- ACCIÓ (Agencia de la Competitividad de la Empresa)minorCatalan government competitiveness agency funding the enzyme-enhanced biogas production R&D project in which Ahidra collaborates with the Bioenergy Cluster of Catalonia and Liquats Vegetals.
- Colsen Group (Colsen B.V.)flagshipIn 2018, the Dutch company Colsen acquired shares in Ahidra and the company became Ahidra Colsen Technologies, forming part of the international Colsen Group. Colsen is a leading Dutch environmental engineering company specializing in biogas, wastewater, and manure treatment technologies. Ahidra acts as the group's Spanish and Portuguese operations and holds exclusive rights to deploy Colsen's proprietary technology portfolio (NAS®, AMFER®, ANPHOS®, BIDOX®, DIGESTMIX®, Poul-AR®, DBIOX®) in these markets. The group jointly pursues large-scale EPC projects including the Bioenergy Factory Barcelona and NILSA Tudela.
- European Research Centers (ManureEcoMine Consortium)minorAhidra participated in the EU ManureEcoMine project alongside four leading European research centers and six national and international companies to develop slurry treatment systems for nutrient recovery and reuse. The project combined new technologies for separating nutrients from slurry for use as natural fertilizers.
- Colsen B.V. (as technology licensor)coreSince 2003, Ahidra has served as distributor of Colsen technology in Spain and Portugal. This commercial relationship deepened in 2018 when Colsen acquired a controlling stake, converting the distribution partnership into a wholly-owned subsidiary within the Colsen Group. Ahidra deploys Colsen's proprietary biological treatment technologies across all three business areas.

Ahidra competitors and assessment
Company assessmentBroad incumbents
- Aqualia (FCC Aqualia): Spain's largest water services company (FCC Group), operating municipal wastewater, desalination, and industrial water reuse concessions. Comparable on Iberian industrial/municipal wastewater EPC, though Aqualia is dominated by concessions rather than project-based anaerobic-digestion plant delivery.
- WABAG Group: Austrian-headquartered EPC contractor for industrial and municipal water and wastewater treatment plants across Europe and emerging markets. Overlapping EPC scope with Ahidra on industrial wastewater and biogas, with substantially larger balance sheet and project pipeline.
- Veolia Water Technologies: Global environmental services leader providing industrial wastewater treatment, biogas, and resource recovery solutions across food & beverage, pharma, and municipal markets. Direct overlap with Ahidra in EPC of high-load wastewater and anaerobic digestion, but at significantly greater scale and geographic reach.
- SUEZ Water Technologies & Solutions: International water and waste management group operating across industrial wastewater, biogas, and circular-economy resource recovery. Competes with Ahidra for industrial and municipal EPC tenders in Iberia and southern Europe; broader portfolio but lower specialization in anammox-based nitrogen removal.
- Hitachi Zosen Inova (HZI): Swiss-headquartered EPC and technology provider for anaerobic digestion, biogas upgrading, and biomethane grid injection. Directly comparable on EPC delivery of organic-waste-to-biogas/biomethane plants — a market segment Ahidra also targets (Bioenergy Factory, NILSA Tudela).
- Acciona Agua: Spanish water infrastructure and treatment business within ACCIONA, an existing Ahidra partner/customer. EPC contractor for industrial and municipal water/wastewater treatment; comparable Iberian footprint, but operates as a broader infrastructure player rather than a niche anaerobic-wastewater specialist.
Emerging players
- BTS Biogas: Italian EPC and technology company specializing in anaerobic digestion, biogas/biomethane plants, and agricultural/manure valorization. Comparable scope on thermophilic digestion and agricultural organic-waste valorization, with similar mid-sized EPC profile in southern Europe.
Direct peers
- Colsen B.V. Dutch parent and technology licensor of Ahidra. Colsen develops the proprietary biological treatment portfolio (NAS®, AMFER®, ANPHOS®, BIDOX®, DIGESTMIX®, Poul-AR®) that Ahidra deploys in Iberia, and jointly pursues large EPC projects such as Bioenergy Factory Barcelona and NILSA Tudela. Directly comparable in technology stack and project profile.
- PAQUES: Netherlands-based biological treatment company offering anammox-based nitrogen removal (ANAMMOX®), biogas desulfurization (THIOPAQ®), and UASB/industrial wastewater technologies. Closest technology competitor to Ahidra's stack and serves overlapping dairy, food, and pulp/paper clients across Europe.
Others
- Valalia / Prezero: Disclosed Ahidra customer (Prezero) and sister entity of Verdalia/Valalia. Acts as waste-management customer/partner rather than direct EPC competitor, but operates overlapping biomethane and organic-waste infrastructure projects in Iberia and is a credible buyer of Ahidra's technology stack.
