About KRdL

The scope of the VDI/DIN Commission on Air Pollution Prevention - Standards Committee comprises all questions within the field of air quality, e.g. origin and prevention of emissions, questions of waste disposal and solid waste, thermal use, environmental meteorology, effects of pollution and techniques for emission and ambient air measurement as well as waste gas cleaning and dust separation technologies including operation and maintenance of corresponding plants within the field of environmental protection. In this context especially requirements of plant-related, cross-media, integrated and ecological environmental protection are considered.
