The Bagarmossen system has been in operation since 1971.
One curiosity is that both 400 and 500 millimeter transport pipes are used in the same system. The reason is simple, when 150 new apartments were added to the system it was decided to use 400 mm pipes instead.
Bagarmossen was recently used as test plant by the City of Stockholm, for testing “the green bag solution” for food waste.
By 2018, a minimum of 50 percent of food waste of the population in Stockholm, will be collected and turned into biogas. In order to reach the goal, the City of Stockholm needs to establish more technological solutions in addition to what already exists.
During 2013 the City of Stockholm, together with two of the City’s housing companies, Stockholmshem and Familjebostäder, carried out a test with approx 2.800 households participating. The food waste was separated in the households and collected in a green bag for subsequent optical sorting. Bagarmossen was one of the areas that was included in this test.
The purpose of the green bag test was to increase the knowledge about how optical sorting, for collection of food waste, could be established in Stockholm. The test has been conducted with apartment buildings that have one of the following three collection systems: underground containers, mobile vacuum waste system or stationary vacuum waste system.
