The Hammarby Model Energy Waste Water and sewage
Energy Combustible waste is converted into district heating and electricity. The heat from the treated wastewater is converted into district heating and cooling. Solar energy is converted into electrical energy or used to heat water.
Water & Sewage A pilot sewage treatment plant facility has been built to evaluate new sewage treatment techniques. Biogas is extracted from the digestion of sewage sludge. Rainwater from streets is filtered locally, settled and then drained into lake Hammarby - not into the wastewater treatment plant.
Waste An underground automated waste disposal system reduces the transport in the area and makes it easy to sort the waste. As does a block based system of recycling rooms and area-based environmental stations. All recyclable material Is recycled: newspapers, glass, cardboard, metals, etc.
