Using Resources Efficiently & Controlling Hazardous Chemical Substances
Against the backdrop of economic globalization and the rapid economic development of emerging nations, the depletion of various resources and environmental pollution are becoming cause for concern. With a goal of achieving Zero Emissions, Tsubaki strictly controls the chemical substances it uses based on laws and regulations in addition to hastening efforts to reduce waste and recycle.
Waste reduction and recycling
The Tsubaki Group takes a proactive approach to reducing and recycling waste. In the fiscal year ended March 31, 2017, the combined total amount of industrial and non-industrial waste emissions was 6,617 tons, representing a increase of 14.5% year-on-year. The recycling rate remained high at an annual average of 98.7%.
Contributing to waste reduction through eco-packaging
The Tsubaki Group is involved in efforts to reduce waste by optimizing product wrapping and packaging such as standardizing wrapping and packaging materials, making products easier to disassemble, and promoting the 3Rs (reduce, reuse, and recycle). For example, Motion Control Division employs eco packaging for compact gear motors (those under 30 kg). This new packaging method replaces the conventional system of plywood, braces, and bolts and nuts with one using only corrugated cardboard and stretch film. The new method has made a significant contribution to reducing timber usage and man-hours required to dispose of packaging waste after delivery.
Initiatives to reduce the use of hazardous chemical substance
Based on domestic and international legislation concerning hazardous chemical substances, The Tsubaki Group investigates substances contained in raw materials, parts, and other materials. In addition to gaining an understanding of the actual details regarding the usage of hazardous chemical substances and establishing permissible levels together with our customers, we continually strive to reduce the use of such substances.
|Laws and Regulations||Compliant Products|
|RoHS directive*1||General-purpose drive chains, Power-Lock (locking devices), couplings (shaft couplings), and reducers, other items|
|ELV directive*2||All components for automotive engine timing drive systems|
*2 An EU directive restricting the use of lead, mercury, cadmium, and hexavalent chromium as a general rule to reduce waste from end-of-life vehicles (ELVs) and encourage appropriate disposal.
*3 Comprehensive EU regulations for the registration, evaluation, authorization, and restriction of chemical substances.
Promoting the reduction of the use of chemical substances subject to the PRTR Law
The Tsubaki Group surveys emissions of chemical substances specified by the Act on Confirmation, etc. of Release Amounts of Specific Chemical Substances in the Environment and Promotion of Improvements to the Management Thereof (known as the "PRTR Law") and works to reduce the use of such substances. In the fiscal year ended March 31, 2017, the group's annual PRTR report covered eight substances from six companies and eight plants.
At our relevant work sites, we are taking steps to reduce the use and emissions of these substances.

*1 As of October 1, 2017, Tsubaki E&M Co. merged into Tsubakimoto Chain Co.
Promoting green procurement
Working together with our business partners (suppliers), we are engaged in efforts toward the effective reduction of hazardous chemical substances contained in our products. In 2006, we established "Green Procurement Guidelines" followed by "Restriction and management standards for inclusion of hazardous chemicals in procured items" in 2007. The Tsubaki Group defines detailed standards for the allowable concentration of individual chemical substances for all Tsubaki Group products containing procured items, and when necessary, request that suppliers submit a "Certificate of non-inclusion of regulated substances". Moreover, in the event that the concentration of a chemical substance in a procured item exceeds the allowable range when the results of an investigation into chemical content are analyzed, we request that the supplier provides a "Confirmation sheet for inclusion of hazardous chemicals and schedule for reduction of use". We then follow up on the issue on an ongoing basis to ensure that the matter is corrected and that improvements are made.
