Envac designed 300 waste inlets across an underground pipe network spanning 3,000m – an average of one inlet every 10 metres – to ensure comprehensive coverage and ensure maximum uptake from the 2,400 apartments and school that currently use the system.
Working closely with Stora Ursvik, Envac also developed a system that would maximise ground level space and enable the areas typically reserved for bin storage rooms to be used for additional residential living and commercial purposes.
In keeping with Envac’s ‘out of sight, out of mind’ philosophy, all waste is now transported underground at programmed intervals or when the inlets are full and waste collection vehicle movements and emissions have been significantly reduced.
One of the most notable additions to the system is the 250 sq. m green wall, which covering one wall of the Envac collection station. It contains of 10,000 plants with 67 different varieties. The plants are chosen to attract butterflies, bees and other insects.
The living wall has ensured that even one of the only above-ground components in the Envac system blends into the environment.
The collection station is also the first BREEAM certified industrial building in Sweden, having achieved the international standard’s Excellent rating.
On the development’s completion in 2035 Envac will handle the waste of at least 8,500 apartments.
