What Aik Technik does

AIK Technik AG is a Swiss plant engineering company (Anlagenbauer) founded in 2018 in Sursee, Canton of Lucerne, that designs and delivers turnkey wet-chemical process plants for residue treatment, wastewater purification, and material recovery. The company's core technology portfolio centers on aqueous-phase chemical treatment systems — washing, extraction, filtration, and ion exchange — applied to waste streams from municipal waste incineration and construction/industrial processes. Proprietary processes include FLUWA (acid fly ash washing, registered trademark) which treats more than 50% of Switzerland's fly ash volume, FLUREC (zinc recovery), the Leaching Reactor (slag processing with patented LR1000 next-generation model), Leachphos (patented phosphorus recovery from sewage sludge ash), and the RESINA ion exchange resin line. Integrated offerings span mercury removal (~98% efficiency), candle filtration, activated carbon and PFAS separation, optical sorting for aggregates, and wastewater treatment (ABA), all engineered to 3D/BIM standards and delivered with in-house laboratory support.

The company serves three primary segments: Swiss and international municipal waste-to-energy operators (KVAs), the construction and aggregates industry (gravel pits, excavation contractors, soil washing plant operators), and industrial process-water customers (energy, chemicals). It holds dominant Swiss market share at 26 of 30 domestic waste incineration plants and has delivered flagship international references including two parallel FLUWA units at Singapore's Tuas Nexus IWMF, a Statkraft wastewater upgrade in Norway, the RagnSells Salarium project in Sweden, and MVA Ingolstadt in Germany. Revenue is generated primarily through project-based turnkey contracts covering design, fabrication, installation, and commissioning, supplemented by engineering/consulting services, aftermarket spare parts and maintenance, and recurring RESINA resin sales. AIK Technik AG operates exclusively through direct enterprise sales with no intermediaries, leveraging a free advisory consultation as a key lead-generation tool and maintaining active trade show presence at IFAT, WETEX, RWM, WEF Davos, and Oman Sustainability Week to reach municipal and industrial decision-makers across Europe, the Middle East, and Southeast Asia.

Revenue model

1. Turnkey Plant Design, Construction & Installation: AIK Technik AG designs, engineers, and delivers complete turnkey plants ( schlüsselfertige Anlagen) for residue treatment and material recovery. Revenue is generated through upfront project-based contracts covering design, fabrication, delivery, installation, commissioning, and handover. Projects range from retrofits of existing plants to greenfield installations. Examples include the Tuas Nexus FLUWA (two parallel units) and the TIB soil washing plant.
2. Engineering, Consulting & Process Optimization Services: Services include feasibility studies, concept development, 3D/BIM design, construction supervision, process optimization on-site, partial and total project management, and plant analyses. Billed as project-based professional services or retainer arrangements.
3. Aftermarket – Spare Parts & Maintenance: Own spare parts warehouse enables rapid response for maintenance and repairs. Service bus enables on-site maintenance. After-sales service includes supply and management of spare and wear parts as part of quality management. Filter press plates and cloths, ion exchange resins (RESINA), and chemical consumables are sold as recurring revenue items.
4. RESINA Ion Exchange Resins (Product Sales): Sale of proprietary ion exchange resin products (RESINA) for mercury and heavy metal removal. Customers purchase resin products directly for use in their own facilities.

Core offering

AIK Technik AG is a Swiss plant engineering company that designs and delivers complete turnkey process plants for residue treatment and material recovery. Its portfolio spans wet-chemical processes — including FLUWA acid fly ash washing, FLUREC zinc recovery, Leachphos phosphorus recovery, the Leaching Reactor for slag, ABA wastewater treatment, and RESINA ion exchange resins — integrated with standard mechanical components (candle filters, activated carbon filters, optical sorters, chamber filter presses) for waste incineration operators, construction and aggregates firms, and industrial process-water customers.

Product overview

AIK Technik AG is a Swiss plant engineering company (Anlagenbauer) specializing in residue treatment and material recovery. The company offers a comprehensive portfolio of proprietary technologies organized into two main divisions: Waste Incineration (Kehrichtverbrennung) and Construction Materials Processing (Steine und Erden). The waste incineration division centers on the FLUWA (acidic fly ash washing) process as the core technology, complemented by mercury separation, candle filtration, FLUREC zinc recovery, and wastewater treatment (ABA). The construction materials division provides excavation/soil washing plants, optical sorting, sludge treatment, and PFAS separation solutions. The company also offers the proprietary Leaching Reactor for slag processing and the Leachphos process for phosphorus recovery. These technologies are delivered as turnkey plant systems with associated laboratory services and after-sales support.
