This Algae pilot is the first of its kind in Sweden. The algae convert unwanted substances to utilities. The goal is that algae cultivation will reduce our emissions of carbon dioxide and purify waste water to minimize over-fertilization of our waters and at the same time produce an energy-rich algae mass that is raw material for biodiesel (algae with high fatty acid content), animal feed (protein-rich algae) etc.
Alsterbro Wastewater Treatment Plant
At Alsterbro sewage treatment plant, wastewater is purified in three steps. The first purification step consists of the mechanical removal of the coarse solids in the rotary screen. The next processing step is the biological treatment in biorotor. In the last purification step, chemical precipitation to remove phosphorous. The flocculant used is polyaluminiumhydroxiklorid.
Then, the treated water out of the Alsterån. Sludge from both the biological and chemical purification pumped into reed beds, where lush reeds contributes to the degradation of the sludge, among others. alia by reed plants favors oxygen supply down in the sludge.
Cleaner air in Stockholm with sewage sludge
Two sewage treatment works in Stockholm are producing biogas from sewage sludge. After having purified the gas, it can be used for both heating and vehicle fuel and in addition creates no net emissions of carbon dioxide. Consequently, the treatment works have reduced their amount of emissions and become energy suppliers. Therefore, sewage sludge is no longer an environmental problem, but an important energy resource.
CLIRE – Climate Friendly Health and Care
The CLIRE project consists of four sub-projects, each focusing on a particular aspect of health care management with substantial potential for improvement in terms of sustainability and the use of clean technologies and practices. The first three sub-projects are managed by the healthcare management organization of Region Skåne.

Dåva Landfill and Waste Center with a 1000-year perspective
Dåva Landfill and Waste Center in Umeå AB (Dåva DAC) takes care of many types of waste. Some examples are ashes from waste incineration and combustion of biofuels, contaminated soils, various waste products from the industry, waste for landfill from households and businesses, asbestos and sulphide soil. We see this as exciting wastes, often with great potential of recycling. We work with flexible solutions, in order to recycle as much as possible.
