The Helsinki Region Environmental Services have branded their six waste-receiving recycling centres as Sortti Stations. They are a significant part of the circular economy in the Helsinki metropolitan area. At the stations, customers can bring small or large amounts of different kinds of waste to be recycled or processed.

The Kivikko Sortti Station development project consists of three new buildings, a new entrance canopy for vehicle access, and a functional change and renovation of the existing customer service building. The buildings are set on the Sortti Station site's edge.

The buildings of the Sortti Station are clad in titanium zinc sheets recycled from the Kiasma Museum of Contemporary Art in Helsinki. Usually, zinc sheets are recycled by melting them to make new products, but in this case, they were removed intact and shaped into a new form for reuse. To minimise wasted material, the long titanium zinc strips used in Kiasma were cut and folded into square sheets to form the herringbone facade cladding of the new buildings. The recycled titanium zinc is technically new. Still, after 25 years of use, it has acquired a beautiful patina on its surface, visible on the facades of the Sortti Station buildings.

The frames of the new buildings at the recycling station were assembled on-site from timber elements. Green concrete was used for the buildings' foundations and courtyard structures.
