Environmental Report

Reduction of Environmentally Hazardous Substances

The Lintec Group complies with relevant laws and regulations in and outside Japan and strives to reduce its use of chemical substances that have an impact on the environment.

Compliance with PRTR*

In fiscal 2020, Lintec reported the use of toluene, xylene, and other substances designated under the PRTR, and the total quantity of these PRTR chemicals was 6,692 tons. Toluene accounted for approximately 99%, the largest portion of the total amount, standing at 6,614 tons, down 1,038 tons from the previous year due to a decrease in the production volume. Emissions of toluene into the atmosphere were 399 tons, down 65 tons from the previous year, and the transferred amount was 496 tons, down 133 tons from the year before. While the overall amounts of use and emissions fell due to the decrease in production volume, the transferred amount (amount of effluent) increased, presumably because the number of washes increased due to the smaller quantity for each product. Lintec has installed treatment facilities to remove atmospheric emissions of organic solvents. Its plants are not permitted to manufacture products without operating these treatment facilities. In fiscal 2020, there was no case where a plant did not operate these treatment facilities during production.

  • *PRTR: Formally named the Act on Confirmation, etc. of Release Amounts of Specific Chemical Substances in the Environment and Promotion of Improvement to the Management Thereof.

Management of chemical substances, compliance with EU regulations

Lintec has specified substances subject to environmental impact examinations, and examines these substances in the raw materials it purchases. The company properly grasps and manages its use of chemical substances to comply with related laws and regulations, and communicates information to customers. Under the REACH Regulation*1, additional substances have been included in the Candidate List of substances of very high concern (SVHCs), on which information must be communicated. As a result of the 24th update, there are now a total of 211 SVHCs on the REACH Candidate List. Meanwhile, the RoHS Directive*2 was revised to expand the scope of its application. In the revised RoHS Directive, four phthalate esters were specified as restricted substances, in addition to the six substances whose use had already been regulated. The four new substance restrictions were brought into effect in July 2019. Lintec is working on switching over to raw materials containing no phthalate esters to ensure that its products are friendly to the environment.

  • *1REACH Regulation: A chemical substance regulation in the EU on the ""Registration, Evaluation, Authorization and Restriction of Chemicals"". Registration is required when exporting a chemical substance into EU states in quantities of one metric ton or more per year. Notification must also be submitted to the authorities when a chemical substance falling under the category of ""candidate for required authorization"" is present in a product at more than 0.1 percent of the mass of the object.
  • *2RoHS Directive: EU's Directive on the restriction of the use of certain hazardous substances in electrical and electronic equipment.

Chemical Leak Drills

The Lintec Group conducts chemical spill drills at plants and research centers that handle chemical substances. The drills aim to familiarize employees with actions required to be taken in the event of a chemical spill, including immediate initial actions, steps to prevent possible secondary disasters, such as a spill extending to outside the premises, soil contamination, and fire, and safe methods of clearing the contaminated area.
In fiscal 2020, drills were carried out at nine business sites, excluding the Head Office, which does not handle organic solvents defined by the Industrial Safety and Health Act. The total number of participants was 1,357.
