Air pollution abatement through business process improvement and technology implementation

Provide and utilize exhaust gas treatment processes

To protect the atmospheric environment, emission standards have been established for soot and dust and VOCs, etc. The NAGASE Group provides wastewater and exhaust gas treatment technology solutions along its supply chain to meet these emission standards. In addition, the Group's manufacturing sites also install scrubbers to reduce emissions of hazardous gases and other pollutants.We also have our exhaust gas concentrations measured regularly by a third party.
Use of substitutes or less hazardous substances

Provide less hazardous alternatives

In order to prevent and minimize damage to the human body and the environment caused by handling chemical substances, it is necessary to obtain scientific information on the hazards and toxicity of chemical substances, assess their risks, and handle them appropriately. Since some of the amine curing agent raw materials provided by Nagase ChemteX Corp. are designated as deleterious substances, we provide "Denatite XNR3324/XNH3324" as a less hazardous alternative as a representative adhesive of non-poisonous substances.
Waste Management

Proper disposal of waste and reporting through electronic manifests

The NAGASE Group has established a system for collecting and sorting waste to promote the reduction and recycling of waste from its factories and offices, and has set targets for these efforts in its environmental management system. In addition, in order to ensure that waste disposal responsibilities are fulfilled, on-site checks are periodically conducted on contracted waste disposal companies to confirm that waste is being disposed of properly.

In accordance with the partial revision of the Waste Disposal and Public Cleansing Law (hereinafter referred to as "Waste Disposal and Public Cleansing Law") to strengthen measures against improper disposal of waste, businesses that generate 50 tons or more of specially controlled industrial waste will be required to use electronic manifests starting in FY2020, and we are implementing reporting We have been implementing electronic manifest reporting.
