The BAT (Best available techniques) guides the environmental permits of waste management directive institutes and requires waste management companies to compile air emission surveys. The client of this thesis Kuusakoski Oy is mainly focused on metal recycling. Required by the environmental permit to the Uusimaa ELY Center, Kuusakoski Oy had to perform the emission inventory and fugitive emission study. Air emission studies were performed at the metal waste crushing plant at the shredder yard in Vantaa. The suitable consulting companies were selected for the air emission measurements. By analyzing the emission measurements, information was collected from where and how much emissions were generated from the crushing process and how far they spread. Shredding caused the most emissions, and the emissions from shredding also spread the farthest into the environment. The highest concentrations were measured for volatile organic compounds (VOC), and they will be monitored better in future air emission measurements. However, all the concentrations of the compounds measured in the emissions inventory and the diffuse emission survey were below the comparable limit values. Since the emissions were minor, there was no need to develop emissions management. The wider significance and necessity of the thesis is based on the objectives of the industrial emissions directive to protect the environment and health.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2022-11-14T06:32:17Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2022-11-14T06:32:17Z (GMT).
