Bluegreen has delivered prefabricated PE-pipe components such as spools and bends, installed PE-pipes and fittings in the hazardous waste facility at Langøya, and taken responsibility for all non-metallic piping. The project combines precise prefabrication and advanced solutions to support sustainable hazardous waste management.
The main activity at Langøya involves receiving industrial acid, fly ash from incineration plants, and other inorganic hazardous waste from Norwegian industries. The current process binds heavy metals like lead and mercury into stable gypsum, ensuring that the metals are stabilized in the gypsum and do not leak out.
NOAH is now constructing a new dewatering facility for hazardous waste at Langøya, designed to extract water from the gypsum. The dry gypsum elements will be used to rehabilitate the island above sea level. In contrast, the wet gypsum slurry from the current process has been deposited below sea level in craters formed by 100 years of limestone mining.
Granitor holds the main contract for the construction of the facility and has engaged Bluegreen as the responsible party for non-metallic piping.
The assignment includes prefabricating pipe spools and bends in PEHD, which are prefabricated at our workshop in Bamble.
Afterward, we install the pipe components into buildings and pipe racks at the facility on Langøya.
The project primarily uses pipes with dimensions ranging from D50 mm to D315 mm.
