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 Act*

In fiscal 2016, Lintec used nine substances that are subject to PRTR reporting. The total quantity of PRTR chemicals was 7,826 tons. Toluene accounted for the largest portion of this amount, at 7,730 tons, up 294 tons from the previous year (7,436 tons). Emissions of toluene into the atmosphere were 471 tons, up 30 tons from the previous year (441 tons), but the transferred amount was 467 tons, down 27 tons from the year before (494 tons).

  • *The PRTR (Pollutant Release and Transfer Register) Act is 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. PRTR is a system for ascertaining, aggregating, and publishing data on the amounts of chemical substances released and transferred.

Increased percentage of solvent-free release paper

The central role of release paper and release films is to protect adhesive coated surfaces until adhesive products are affixed to objects. Ease of removal is also important for such products to allow adjustment of peel force according to the type of adhesive, labeling using a labeling machine, and printing and cutout processing. Release agents, generally silicone, are coated onto a paper or film base. To reduce the release of VOCs* into the air, Lintec is working on solvent-free and highly condensed release agents at its plants and Research Center.

The percentage of release paper that was solventfree in 2016 was 56% (production basis), remaining at the same level as the previous year.

To further increase the percentage of solventfree release paper, the Research Center is working on purpose-specific design and development with a focus on the structure of release agents. The center also cooperates with plants to refine coating technology.

We will continue to improve design and development and coating technology for the development of products with low environmental impact.

  • *VOCs: VOCs stands for volatile organic compounds. VOCs collectively refers to organic compounds that become gas in the atmosphere.

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 fiscal 2016, Lintec updated the list of environmentally hazardous substances for its supplier survey.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.)

Product Information Flow
  • *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 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 2016, drills were carried out at the Mishima Plant, Agatsuma Plant, Kumagaya Plant, Komatsushima Plant, Chiba Plant, Tatsuno Plant, Ina Technology Center, Research Center and Niihama Plant.

Proper Storage and Management of PCB*

Lintec properly disposed of eight units containing high-concentration PCBs and five units containing low-concentration PCBs.In fiscal 2016, Lintec properly disposed of one unit containing high-concentration PCBs and 13 units containing low-concentration PCBs. We will securely manage and store high-PCB concentration units that are awaiting disposal.

  • *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 2016, the percentage of solvent-free release paper (production volume basis) was 56.2%. The percentage of solvent-free printing-related adhesive products (sales volume basis) was 73.0%.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.

Implementing Various VOC Reduction Measures

To reduce VOCs, the Chiba Plant is using organic solvents for washing. To reduce the usage of organic solvents, we are also making an effort to increase the concentration of solvent adhesives. As for waste containing PCBs*7, in October 2016, we completed the disposal of all such waste generated at the Chiba Plant. We will continue to make improvement efforts to further reduce our environmental impact.
