NOAH has treatment methods for pollution types connected to clearance work, whether from digging up contaminated soil or pulling down old industrial buildings etc. The methods are predominantly based on stabilising and breaking down pollutants
NOAH specialises in and has documented methods for treating heavy metals in general, and particularly mercury pollutants. We also specialise in receiving and treating organic pollutants such as PAH, PCB, TBT and brominated flame-retardants.
NOAH treats and deposits all types of inorganic pollutants in classes 2-5, as well as hazardous waste. We have a particularly strong receipt solution for contaminated soil, which we receive from all over Norway and Scandinavia. Langøya is the ideal location for shipments of large quantities of contaminated masses from bigger projects that require effective logistics. NOAH has agreements in place with several shipyards and we can adapt individual receipt solutions for much of the Norwegian coastlinr. Our logistical solutions ensure our customers receive effective waste disposal, which is adapted to their particular clearance job. In Oslo harbour, we have established a tip ramp, which helps provide a particularly effective and secure loading onto the boats. NOAH also has a mobile tip ramp, which can be used for larger and more demanding jobs. Transport of contaminated mass via the sea helps reduce city traffic and provides an environment-friendly logistical solution.
NOAH also receives smaller volumes of contaminated mass via truck. We have our own ferry, and we ensure that cars deliver the waste to the island at the agreed time.
NOAH receives 300,000 tonnes of contaminated mass a year. We treat contaminated mass from tough clearance jobs in most Nordic countries.
Construction and demolition waste
Clearance of old industrial buildings often leads to waste fractions with a high content of e.g. heavy metals and organic pollutants such as PCB. NOAH’s treatment plant for hazardous waste is unique in the Nordics and provides a reliable solution for the customer. Typical waste fractions that NOAH receives and treats include concrete, brick and lightweight concrete. There may also be waste such as asbestos, steel constructions and other plastic/rubber constructions that are not degradable. We will gladly assess waste fractions beyond those mentioned above, for further pre-assessment.
NOAH’s treatment method on Langøya involves stabilising and breaking down the pollutants. Our methods are well documented for all pollutant types we receive.
NOAH’s treatment plant is highly suitable for special pollutants found in polluted sediment. Our receipt capacity and sea transport makes the solution simple, cost-effective and environment-friendly. Transporting sediment by sea is often the only practical solution when clearing the seabed. NOAH uses secure boats for safe transport. These are equipped with longitudinal bulkheads to secure the load.
NOAH’s treatment method on Langøya involves stabilising and breaking down the pollutants. The methods are well document for all current pollutant types, including heavy metals, PAH, TBT and brominated flame-retardants.
NOAH has a permit to receive alun slate. Black shales from alun shale Formation is normally highly acid-forming, and through oxidisation releases heavy metal contamination. On Langøya, NOAH makes a gypsum slurry that is particularly effective at stabilising all forms of shale. Alun shale comes mainly from building activity in the Oslo region. We can provide flexible receipt solutions, via sea from Oslo harbour and via our own car ferry accessed by road.
