Air Pollutant and Odor Assessments

Our services:

Odor Assessment Report

• We can draw up an odour assessment in accordance with the FOEN Odours Recommendation.
• We can draw up immissions forecasts using computer modelling.
• We develop clean-up concepts to prevent odour immissions.
• We measure odor emissions using olfactometry at facilities or in exhaust air.

Air Pollutant Exposure Assessments and Exhaust Air Treatment Plans

Do you need an assessment to determine whether excessive emissions are occurring, or a remediation plan to reduce emissions from your business or facility because it no longer meets the requirements of the Clean Air Ordinance?

• We use computer models to generate emission forecasts for assessing air pollutant emissions from facilities.
• We can help you to develop measures designed to mitigate immissions.
• Exhaust Air Treatment: As manufacturer-neutral consultants, we evaluate the best solution for reducing pollutant emissions from your facility.
• Reduction of fugitive emissions: We advise you on how to use cutting-edge technology to reduce fugitive VOC and dust emissions.

Emissions Statement and VOC Inventories

• VOC reports: We can draw up or check your VOC emissions report in accordance with Article 10 of the Swiss Ordinance on the Incentive Tax on Volatile Organic Compounds (OVOC).
• Emissions Report, Emissions Inventory: We prepare the emissions declaration for your facility in accordance with Article 12 of the Clean Air Ordinance, including all information required for the assessment, such as emissions per air pollutant per hour or per year, emission point, stack height, etc. For new facilities, we prepare the emissions forecast.

Stack height calculations

• We determine the required stack height for your facility in accordance with Appendix 6 of the Swiss Air Pollution Ordinance or in line with the stack recommendations issued by FOEN.
• Where necessary or required, we can optimise the stack height by means of an immissions assessment.

Air pollution control on construction sites

• We can assess the emissions impact of construction sites and draw up the necessary measures in accordance with the FOEN guidelines on air pollution control on construction sites.
• We can assess the emissions impact of building contractor transport and draw up the necessary measures in accordance with the FOEN guidelines on air pollution control on construction sites.
