Environmental and social benefits of improved handling and disposal of black wastewater in Greenland
Wastewater collection and treatment is difficult in arctic climate due to, i.e. permafrost and cold climate. Currently all toilet wastewater (blackwater) in Greenland is discharged untreated, mainly to the sea. Water from bathing, washing and kitchen (greywater) is usually not collected and is disch...

Wastewater collection and treatment is difficult in arctic climate due to, i.e. permafrost and cold climate.
