   Sammanfattning : The effects of greenhouse gas net emissions on global warming, stricter legislation on waste handling, and the pursuit of ever cheaper heat- and power production are all important factors driving the introduction of complex fuels in incineration plants. However - without fundamental knowledge regarding ash transformation, corrosion control, and materials selection – this introduction of potentially economically and environmentally beneficial fuels, might instead cause economic loss and environmentally adverse effects.

   Sammanfattning : For a development to be considered sustainable, social, economic and environmental requirements must be met. The Swedish sustainable development goals, based on Agenda 2030, contain 16 national environmental quality goals. The National Board of Housing, Building and Planning is responsible for achieving the goal "A good built environment". LÄS MER
