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 2017, Lintec used nine substances that are subject to PRTR reporting. The total quantity of PRTR chemicals was 7,838 tons. Toluene accounted for the largest portion of this amount, at 7,752 tons, up 22 tons from the previous year due to an increase in production volume. Emissions of toluene into the atmosphere were 482 tons, up 11 tons from the previous year, and the transferred amount was 483 tons, up 16 tons from the year before.

  • *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 2017 was 55.1% (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, properly grasps and manages its use of chemical substances to comply with related laws and regulations, and communicates information to customers. The company is fulfilling its reporting obligations under the REACH Regulation*1 and the RoHS Directive*2. Starting fiscal 2017, Lintec has been making preparations for compliance with chemSHERPA*3 to build a system for more accurate and efficient information communication.

  • *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.
  • *3chemSHERPA A scheme, recommended by Japan's Ministry of Economy, Trade and Industry, for communicating information about chemical substances contained in products. The mechanism is aimed at properly managing chemical substances contained in products across supply chains, from upstream to downstream, to ensure continued compliance with tighter regulations.

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 2017, 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*

In fiscal 2017, Lintec properly disposed of 38 units containing high-concentration PCBs (from storage at the Research Center). We will securely manage and store high-PCB concentration units that are awaiting disposal.

Status of Proper Storage and Management of PCB in Fiscal 2017
Site name Number of stored units of PCB waste Treatment facility Year of registration for consignment treatment Expected processing completion
Kumagaya Plant 24 JESCO Tokyo Office FY2005 FY2018
Tatsuno Plant 14 fluorescent light ballast JESCO Kitakyushu Office FY2015 FY2019
Total 38 (34 high-concentration units, 4 fluorescent light ballasts)

  • *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 2017, the percentage of solvent-free release paper (production basis) was 55.1%. The percentage of solvent-free printing-related adhesive products (sales basis) was 73.7%. The percentage of solvent-free paper and products remained at the same level as in the past.
Recognizing the importance of further reducing VOCs for preventing air pollution by businesses, Lintec is planning and implementing VOC reduction measures. Lintec has completed the installation of exhaust gas treatment facilities, and will continue to ensure reliable management of treatment facilities, manage the percentage of solvent-free products, and develop and promote sales of solvent-free products to further reduce its environmental impact.

Introducing VOC Treatment Facilities to Comply with Revised Law

South Korea revised its Clean Air Conservation Act in 2015 to expand the scope of control to cover air containing volatile organic solvents generated from facilities other than VOC-emitting facilities. To treat low-concentration VOCs from its clean room, Lintec Korea, Inc. installed two concentrators and one RTO-based exhaust gas treatment system and started their operation in November 2016. VOC emissions in fiscal 2017 were reduced by about 7 tons from fiscal 2016. We will continue to reduce VOCs.
