What NOAH does

NOAH AS is a Norwegian environmental services company founded in 1993 and headquartered in Holmestrand, Norway, fully owned by Gjelsten Holding AS. The company specializes in receiving and treating inorganic hazardous waste generated by Nordic industrial companies, waste incineration plants, and the construction sector. Its primary site is the Langøya island facility, a former limestone quarry where fly ash from waste-to-energy incinerators and sulfuric acid from industrial processes are chemically neutralized and stabilized into gypsum that is used to rehabilitate the island's exhausted quarries. The process is formally recognized by EU authorities as Best Available Technology (BAT) and classified as a recovery (R-process), and permits allow up to 1,000,000 tonnes of inorganic hazardous waste per year. In 2021, NOAH handled roughly 1.31 million tonnes across hazardous, ordinary, and inert waste streams.

NOAH operates as a B2B waste services provider with a per-tonne, quote-based transaction-fee model across four revenue streams: hazardous waste treatment and disposal at Langøya, ordinary/inert fill for landscape rehabilitation, surplus-mass disposal at Engadalen (Oslo region, up to 750,000 tpy capacity), and high-quality stone products for coastal protection and offshore wind through subsidiary Rekefjord Stone AS. GTM is sales-led, executed through dedicated country sales managers in Norway, Denmark, and Sweden, supported by channel partners (Bech Gruppen, Norrecco AS) for reception and interim storage outside Norway, and a customer portal (kunde.noah.no) for appointment scheduling. Sea logistics via two Langøya quays (boats up to 3,800 tonnes) are a core cost and capability advantage.

Beyond disposal, NOAH operates a 10-person R&D department developing circular-resource technologies including ReSalt (industrial salt recovery), Askepott (fly ash/sulphuric acid value recovery), and Carbontech (CO2 reuse). The group structure includes NOAH Solutions AS (Langøya operations), NOAH Environment AS (Engadalen, Rekefjord), and NOAH Engadalen AS (inert waste). NOAH holds ISO 9001, 14001, and 45001 certifications, recently committed NOK 300 million to a dewatering facility that extends hazardous waste reception to 2030, and is co-investing in Morrow Batteries and the FRANO soil-washing joint venture with Franzefoss to extend into adjacent waste streams.

Revenue model

1. Hazardous waste treatment and disposal fees: NOAH charges industrial companies and incineration plants for safe receipt, treatment, neutralisation, and disposal of inorganic hazardous waste including fly ash, contaminated soils, acids, and industrial byproducts. Revenue is generated through per-tonne fees based on waste volume and type. The company holds permits for up to 1,000,000 tonnes of waste per year.
2. Ordinary/inert waste disposal fees: NOAH accepts ordinary waste and inert fill (contaminated masses, sediments, excavation waste) for use in rehabilitating Langøya after limestone extraction. Fees are based on volume and contamination class.
3. High-quality stone products (Rekefjord Stone AS): Through its subsidiary Rekefjord Stone AS, NOAH produces and exports high-quality stone products to Europe for coastal protection, offshore wind development, and asphalt production.
4. Surplus masses and inert fill services: NOAH Engadalen receives surplus masses from construction projects in the Oslo region, shaping landscapes and creating new agricultural areas. Fees are based on volume received, with capacity of up to 750,000 tonnes per year.

Core offering

NOAH provides treatment, neutralization, and stabilization of inorganic hazardous waste on a former limestone quarry island at Langøya, Norway, where fly ash, industrial acids, contaminated soils, and heavy-metal-bearing waste are chemically stabilized into gypsum that is then used for landscape rehabilitation. The company also accepts ordinary and inert waste for use as fill material, processes 300,000+ tonnes of fly ash annually from northern European incineration plants, and delivers tailored logistics via sea and road transport under per-tonne service contracts with industrial customers.

Product overview

NOAH is an environmental and resource company offering hazardous and inert waste management services primarily at its Langøya facility outside Holmestrand, Norway. The company operates as a unified service portfolio organized around waste treatment operations: core services include hazardous waste treatment (stabilizing fly ash, industrial waste, and contaminated soils in gypsum at Langøya), ordinary waste reception for landscape rehabilitation, and inert waste disposal at Engadalen for agricultural land creation. R&D projects include ReSalt (salt recovery), Carbontech (CO2 reuse), and fly ash-based cement/concrete products. The subsidiary Rekefjord Stone produces construction materials for coastal protection and offshore wind. Logistics operations support customer deliveries via sea and road transport. NOAH also participates in Morrow Batteries for sustainable battery production, leveraging its processing industry expertise.

Products and services

• Hazardous Waste Treatment (Langøya) Treatment and stabilization of inorganic hazardous waste including fly ash, contaminated soil, acids, and industrial byproducts. The process neutralizes hazardous substances chemically and stabilizes them in gypsum for safe disposal in former limestone quarries at the Langøya facility. Targeted at industrial waste generators and waste incineration operators across the Nordics.
• Ordinary Waste Reception Reception and disposal of ordinary and inert waste including contaminated masses from construction projects, harbor sediments, and demolition waste. Used for landscape rehabilitation of Langøya after limestone extraction. Priced per tonne based on volume and contamination class.
• Inert Waste Disposal (Engadalen) Reception of surplus masses from construction projects in the Oslo region at Engadalen in Nittedal municipality. Transforms barren land into agricultural areas through shaping, compacting, and adding topsoil layers. Operated with fossil-free equipment and net zero CO2 emissions.
• Fly Ash Reception Reception and processing of fly ash from incineration plants. NOAH receives 300,000+ tonnes per year from all of northern Europe. A new NOK 300 million dewatering facility extends reception capacity until 2030 by processing fly ash and gypsum in a chamber filter press.
• ReSalt Salt recovery technology developed by NOAH that achieves high refinement levels for industrial salts (potassium chloride, calcium chloride, sodium chloride) from processed water, with strong market demand for use in other industrial processes.
• Carbontech Development project for re-use of CO2 from exhaust gases in treatment processes to stabilize hazardous waste and develop new products.
• Rekefjord Stone Products Produces and exports high-quality stone products to Europe for coastal protection, offshore wind development, and asphalt production. Operated through subsidiary Rekefjord Stone AS at Hauge i Dalane, Norway.
• Logistics Services (Langøya) Integrated logistics solutions including boat transport with two quays (600-3,800 tonne capacity), car ferry between Holmestrand and Langøya, tipping ramps, and mobile tipping ramp for large projects. Supports cross-border waste reception from Denmark and Sweden.
• FRANO Soil Washing Services Soil washing plant established in collaboration with Franzefoss at Bånkall outside Oslo for recycling large amounts of surplus masses from development projects. Part of the SIRKMASS initiative for environmentally friendly mass management and washing process improvement.
