Waste management and recovery in Helsinki region is mainly handled through so-called Sortti stations owned and operated by Helsinki Region Environmental Services HSY. Customers bring their recyclable waste to a Sortti station and leave it in pallets containing different types of waste, from which they are taken to further recycling.
The Sortti station in Jorvas is the fifth station in Helsinki metropolitan area. It consists of a base building, a container hall and shelters for heavy machinery and pallets. The pallets containing different types of waste are covered by a large canopy with tilted columns that support a massive roof structure.
In order to have as little environmental impact as possible, the above-ground parts of the Jorvas Sortti station have been constructed with wooden structures. The buildings are mainly made of cross-laminated timber panels, ie CLT, and glulam beams and columns. Wood surfaces are visible both indoors and outdoors. The buildings are clad in untreated Siberian larch, which becomes gray with the weather over time. Indoors, CLT and glulam beams are left exposed. The wooden interior surfaces of the base are treated with protective wax, which protects the wooden surface from the darkening effect of light. The station is heated with geothermal heat and there are solar panels on the canopy that provide some of the power used in the station.
