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.

PRTR* Compliance

In fiscal 2015, Lintec used ten substances that are subject to PRTR reporting. The total quantity of PRTR chemicals was 7,528 tons. Toluene accounted for the largest portion of this amount, at 7,436 tons, down 144 tons from the previous year (7,580 tons). Emissions of toluene into the atmosphere were 441 tons, down 21 tons from the previous year (462 tons), and the transferred amount was 494 tons, down 42 tons from the year before (536 tons).

  • *PRTR (Pollutant Release and Transfer Register): a system for ascertaining, aggregating, and publishing data on the amounts of chemical substances released and transferred. The system is based on Japan's Act on Confirmation, etc. of Release Amounts of Specific Chemical Substances in the Environment and Promotion of Improvements to the Management Thereof.

Complying with EU Regulations Concerning Chemical Substance Management and Environmental Preservation

Lintec examines substances with environmental impact in the raw materials it purchases, and conveys the necessary information to customers. The company also issues GHS*1-compliant SDS*2 for its products, complying with regulations in EU where environmental regulations are becoming tighter. In light of the addition of substances subject to the REACH Regulation*3 and the RoHS Directive*4, Lintec is enhancing the management of substances contained in its products. (Currently, about 6,000 substances are regulated.)

  • *1GHS: Globally Harmonized System of Classification and Labelling of Chemicals. GHS provides international standards for the classification of chemicals by types of hazard and a mechanism of labeling.
  • *2SDS: Safety data sheet. This is a document which provides information on the handling of chemical substances when transferring or providing products that contain potentially hazardous chemical substances to another company.
  • *3REACH 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.
  • *4RoHS 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 is stepping up its drills for emergencies such as chemical leaks. In fiscal 2013, drills were carried out at the Mishima Plant, Agatsuma Plant, Kumagaya Plant, Komatsushima Plant, Ina Technology Center, Research Center, Niihama Plant, Chiba Plant and Tatsuno Plant.

Proper Storage and Management of PCB*

In fiscal 2015, Lintec properly disposed of eight units containing high-concentration PCBs and five units containing low-concentration PCBs. By December 2015, the company re-inspected the number of units and confirmed that it owns 77 high-PCB concentration units (including 52 fluorescent light ballasts) and 13 low-PCB concentration units. Lintec will promptly dispose of the low-PCB concentration units, and securely manage and store high-PCB concentration units that are awaiting disposal.

  • Note: Since the Japan Environmental Safety Corporation does not handle the treatment of low-concentration PCBs, Lintec intends to register with other disposal contractors, including private companies.
  • *PCB (polychlorinated biphenyl): The Act on Special Measures concerning Promotion of Proper Treatment of PCB Wastes (PCB Special Measures Law) mandates the proper storage, management, and disposal of wastes containing PCBs.

Reducing VOCs (volatile organic compounds)

Transitioning to Solvent-free Release Agent

Lintec is reducing VOCs. In product design, Lintec is working on switching to a solvent-free release agent for its release paper and solvent-free adhesive for printing-related adhesive products to reduce the amount of organic solvents it uses. In fiscal 2015, the percentage of solvent-free release paper (production basis) was 55.8%. The percentage of solvent-free printing-related adhesive products (sales basis) was 73%. The percentage of solvent-free paper and products remains at the same level, but Lintec will continue to expand sales by promoting the advantages of environmentally friendly products and their benefits to environmental conservation. Meanwhile, the installation of exhaust gas treatment equipment has been completed. Lintec will continue to monitor numerical values, and ensure reliable operation of exhaust gas treatment equipment to reduce its environmental impact.

Improving the Working Environment to Reduce Environmental Impact

Lintec Industries (Sarawak) SDN. BHD. is working on the reuse of secondary materials. For instance, we are collecting and cleaning acrylonitrile-butadiene-styrene (ABS) resin cores for winding products to reuse them. We have also introduced a closed automatic washer to improve the working environment while reducing the amount of solvents used and disposed of.
