Short-lived climate-impacting air pollutants trigger both climate and health issues. Small-scale residential wood burning is major source of these emissions. A study carried out by us on behalf of the Nordic Council of Ministers shows that combustion with a reduced wood load and an inadequate air supply results in higher emissions than normal combustion, this is also happens when unseasoned wood is burned.
Lack of fresh water is a growing problem in many parts of the world. At Hammarby Sjöstadsverk in Sweden we develop techniques that will make it possible to reuse treated wastewater.
