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 2021, Lintec used 6,944 tons of toluene, xylene, and other substances designated under the PRTR law.
Toluene accounted for around 98%, the largest portion of the total amount, standing at 6,800 tons, up 186 tons from the previous year. Emissions of toluene into the atmosphere came to 434 tons, up 35 tons from the year before, and the transferred amount was 516 tons, up 20 tons. The increases in the overall amounts of use and emissions were due to the recovery of production.
Lintec has installed treatment facilities to reduce atmospheric emissions of organic solvents, and is making efforts to maintain their performance, which include conducting checks and cleaning and measuring emission concentrations on a regular basis.

  • 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 purchasing raw materials. 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*, additional substances have been included in the Candidate List of substances of very high concern (SVHCs), for which information must be communicated. As a result of the 27th update, there are now a total of 224 SVHCs on the List (as of June 10, 2022).
As new substances are added to the List in the future, we will promptly obtain the proper information and take action accordingly.
We are also switching over to materials containing no phthalate esters to provide products that are friendly to the environment, while stepping up our efforts to manage chemical substances contained in our products.

  • REACH 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.

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 2021, 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 1,000.
