Design for Environment

We established and are using an original Design for Environment Approval System.

    Design for Environment

    Basic Stance

    The Teijin Group defines Design for Environment as “product design that aims to reduce the environmental impact of each product through evaluating the overall environmental impact throughout the product life cycle including procurement, production, use and disposal” and we are taking measures for the reduction of environmental impact.

    Corporate Code of Conduct

    2.Coexistence with the global environment

    The Teijin Group aspires to ensure society´s sustainable development, to exist in harmony with the natural environment and to cherish nature and life.

    Promotion of Design for Environment

    We established the Teijin Group Design for Environment Guidelines in January 2008, and we design our products based on comprehensive evaluations of their impact on the environment throughout their life cycles. Using a special checklist, we evaluate new and improved designs for products, manufacturing processes and IT/services, review various measures for reducing environmental impact and apply the results of the reviews in product design.

    In FY2013, we reviewed existing issues and directions for the future in order to apply Design for Environment more effectively. In FY2014, we plan to simplify the evaluation method by reviewing the self-checklist and incorporating Design for Environment into R&D processes.

    Summary of the Design for Environment Evaluation Checklist

    • 1.
      Safety
    • 2.
      Energy saving
    • 3.
      Resource saving
    • 4.
      Environmental conservation
    • 5.
      Provision of information
    • 6.
      Environmental impact reduction in the manufacturing stage

    Under the six major items, there are sub-items and spaces for scoring evaluations. The checklist is available in three versions with sub-items/spaces for scoring evaluation relating to either raw materials/materials, finished products, or IT services.

  • Approved Products

    Design for Environment Approved Products
    Earth Symphony®

    This logo is used to promote awareness among the general public of our initiative for harmonization with the global environment through environmentally conscious corporate activities based on the Teijin Group Design for Environment Guidelines.

    Earth Symphony® is the trademark utilized for products and services that have received Design for Environment approval. In FY2013, two products were additionally approved, bringing the total number of Design for Environment approved products to 32. For these products, to ensure reliability of Earth Symphony®, we conduct regular audits even post-approval to evaluate whether or not to continue approval.

    Earth Symphony® has become a registered trademark of the Teijin Group in Japan, the EU, China, Singapore, India and Indonesia.

    Products that Received Design for Environment Approval in FY2013

    Aramid fiber recycled pulp

    We recover products as well as waste fiber and fiber scraps generated in manufacturing processes, turn them into thread or pulp form and reuse them in brake pads and brake linings.

    Environmental Benefits

    Reduced use of natural resources and reduction of CO2 emissions through use of recycled resources

    Artificial leather CORDLEY® (Use of recycled polyester)

    We used recycled polyester for artificial leather CORDLEY® which is used in sports shoes, balls, vehicles, school bags and other applications.

    Environmental Benefits

    Reduced use of natural resources, reduction of CO2 emissions and reduction of chemical substances with large environmental impact through use of recycled resources.

    Supporting Widespread Use of the Guidelines for Calculating Avoided CO2 Emissions

    The Teijin Group has been participating in an LCA working group of the Japan Chemical Industry Association (JCIA) since FY2011. We are working hard to promote the widespread use, both internally and externally, of guidelines for calculating avoided CO2 emissions of chemical products using the c-LCA method.

    It is important for the c-LCA method to ensure transparency and reliability. Based on guidelines prepared by the Japan Chemical Industry Association (JCIA) in 2012, the chemical sector consisting of the International Council of Chemical Associations (ICCA) and The World Business Council for Sustainable Development (WBCSD) jointly prepared global guidelines, Addressing the Avoided Emissions Challenge, in October 2013. In the third edition of the JCIA report (third edition of "Life Cycle Assessment for Chemical Products in Japan and Overseas" ) issued in March 2014, based on the global guidelines, the cases assessing the contribution for reduction in past‒materials for photovoltaic generation, automobiles, airplanes, low-fuel tires, LED-related, residential-use heat insulators, hall elements/ICs for air conditioners, piping, high-durability condominium materials and seawater desalination technology‒were revaluated and evaluations for six cases were also newly added.

    Besides this, Teijin Limited is also participating in an LCA working group of the Japan Chemical Fibers Association (JCFA).
