Green Procurement

Handling of Chemical Substances

Based on our Green Procurement Management Regulations, the Nitta Group conducts management of raw materials, components, and other procured items with consideration of laws and regulations in Japan, customers’ green procurement standards, and other factors, with the aim of curbing our use of hazardous chemical substances.
In carrying out this management, we also pay heed to movements in EU REACH rules and the EU RoHS Directive.

Chemical Substance Management Structure

The Nitta Group has established a chemical substance management system and works toward continuous improvement through activities related to the management of harmful chemical substances and poisonous and toxic substances under environmental conservation managers (chemical substance managers).

Education on Chemical Substance Regulations

Based on regulations for risk assessment of chemical substances, the Nitta Group conducts risk assessments of chemical substances used in raw materials. By conducting risk assessment evaluations every year, we stay on top of the harmfulness of chemical substances, based on up-to-date laws and regulations.
In performing the evaluations, we conduct in-house training for risk assessors and provide information on evaluation methods and the latest revisions to laws and regulations in Japan and other countries.

Reducing Harmful Chemical Substances and Preventing Spills

The RoHS 2 Directive regulates substances that had been widely used as plasticizing agents for rubber and plastics. Our Nara Plant promptly switched from the restricted plasticizers to unrestricted plasticizers, thus preventing the production of not only products previously made using the restricted plasticizers but also preventing contamination of products produced not using these plasticizers but manufactured on the same equipment.
With a focus on raw material safety information related to adhesives used in production, we switched to adhesives not containing specified organic solvents and thus eliminated the use of these organic solvents. By switching to adhesives using non-specified chemicals, we aim to expand the sale of environmentally friendly products, and we have improved employees’ work environment by eliminating specified organic solvents from the workplace.
Moreover, in response to guidelines in the PSEHB/PED Notification “Regarding Storage and Management of Poisonous and Toxic Substances in the Event of Wind and Flooding Damage,” concerning the prevention of poisonous substance outflows due to events such as storms and inundations, we are moving the relevant raw materials and products to higher storage locations as a preventive measure. We also plan to install water gate barriers on shutter doors to prevent outflows due to inundation the buildings, as well as at other entrances and exits. We will continue engaging in activities that reduce the impacts of harmful chemical substances on people and the environment.
