OCEANHAMNEN | HELSINGBORG

IN NUMBERS...

INFO...

Oceanhamnen is a novel water-wise neighbourhood in Helsingbörg, Sweden, constructed on a former harbour plot and part of the “H+” project, in which connections between existing neighbourhoods and the city centre are improved and enriched. This innovative neighbourhood will consist of 343 households, including 3 office buildings and a communal building, the “RECO-lab”: an open and accessible meeting-place for businesses, researchers and public actors for research, development, education and communication regarding sustainability in i.a. city planning and utilities. Grey water is locally treated to meet drinking water standards with ocean discharge of bleed water. Black water is separately collected (vacuum toilet) and digested for nutrient recovery as struvite and ammonium sulphate. Food waste is collected (after processing through a household food waste grinder) in a separate LPS system and treated in a separate UASB-reactor and undergoes the same nutrient extraction steps. Biogas from both digestors is delivered to the centralised gas grid.
