Emissions to the air

The primary source of manufacturing noise is engine test runs and ventilation machinery on factory roofs. This noise is mostly low frequency and is therefore not easily detected by the human ear. Wärtsilä has specifically addressed the issue of noise protection using technical means and we have succeeded in lowering noise levels considerably. However, noise abatement is a continuous need and requires regular monitoring.

Air emissions are mainly caused by test runs and the painting of completed engines or other Wärtsilä products. Test run emissions consist of nitrogen oxides, sulphur dioxide, carbon dioxide and par­ticles, as well as small amounts of other emission components.

The painting of engines and other Wärtsilä products generates VOC (volatile organic compounds) emissions.
