Biolan Oy's Eura production plant is located on the border of the municipalities of Eura and Säkylä along highway 12. The plant manufactures e.g. fertilizer and soil products. The environmental permit for the production plant presents the limit values for environmental noise caused by the operations. The permit also includes an obligation to investigate the environmental noise caused.

Sitowise prepared an environmental noise report concerning its operations in autumn 2023. The noise sources associated with the operation were identified by on-site observation. Noise was found to be caused by, for example, equipment in production buildings, soil screening and machinery. The noise emission of machinery and equipment was determined by measuring on a device-by-equipment basis. The spread of environmental noise was investigated using computational noise dispersion modelling based on a terrain model, the starting data for which were measured results made at the site and data on the transport volumes of materials. The accuracy of the noise modelling results was ensured in the surroundings of the production plant by means of short verification measurements. 

Based on the results of the studies, a written report was prepared that serves as part of the annual environmental reporting of Biolan Oy's production plant. Based on the survey, it was possible to demonstrate that the production plant operates in accordance with the noise restrictions set in the environmental permit and that the operations do not cause significant noise nuisance to residential areas.
