Sustainability / Environmental ReportEnvironmental Management and Prevention of Air Pollution
Guided by its Basic Policies for Responsible Care, the Daicel Group’s efforts extend beyond simply complying with regulatory requirements to further reduce its emissions of air pollutants (sulfur oxides [SOx], nitrogen oxides [NOx], soot and dust). It continually strives to reduce its environmental risk by improving the facilities at each of its plants and periodically monitoring their emissions.
Prevention of Air Pollution
Daicel’s business sites and Group companies in Japan strictly comply with regulatory requirements as well as other requirements as determined through negotiations with local governments and municipalities in regard to total emission volume and the density of specific substances. The Daicel Group in Japan strives to limit its emissions of air pollutants by voluntarily setting targets that are more stringent than required. We are limiting atmospheric emissions of SOx, NOx, and soot and dust through means that include removing it from the air through the use of catalysts, and dust collectors and scrubbers, as well as by choosing fuel that contains no nitrogen or sulfur.
FY2023/3 SOx and soot and dust emissions both dropped year-on-year to 299 tonnes and 30 tonnes, respectively. NOx emissions increased year-on-year to 686 tonnes but held below voluntary setting targets.
- Reduction of SOx through use of stack-gas desulfurization technology
- Reduction of NOx through use of catalysts
- Soot and dust removal using dust collectors for boilers and other combustion equipment
Before formulating a plan for the development of a new product or changing a manufacturing process, we carefully assess the potential impact it may have on air quality using our Total Environmental, Health and Safety Assessment System. We take the appropriate measures to fully address any possible issues before executing the plan.
