Komatsu's Environmental and Social Activities Enhancing Quality of Life

Promoting Recycling  Promoting the Reman Remanufacturing Business

In our Reman business, the Komatsu Group remanufactures used engines, transmissions, and other key components (parts) of construction and mining equipment into "remanned" components that have the same high quality as newly manufactured components. We then put these components back on the market. The Group is promoting the Reman business at eleven Reman Centers around the world.

Promoting the Reman Business to the World

Reman, an abbreviation for remanufacturing, offers the following advantages to customers:

  • ·Quality and performance that is the same as new components
  • ·Lower cost for "remanned" components
  • ·Reduced idle time for construction equipment because of adequate inventory of remanned components
  • ·Resource conservation and waste reduction through reuse and recycling of components.

As the global center, Komatsu established PT Komatsu Reman Indonesia (KRI), which supplies parts, such as engines and transmissions for large-size construction machinery, and PT Komatsu Indonesia (KI), which supplies oil-pressure cylinders. Komatsu also established another global center, Komatsu Reman Center Chile (KRCC), which provides components for electric dump trucks.

Additionally, Komatsu established PT KOMATSU REMANUFACTURING ASIA (KRA) in Indonesia to recycle components of large-size construction machinery. For countries that are not part of our global supply chains, such as China, Russia, and India, we have established individual Reman Centers. For example, in January 2013, we established the eleventh Reman Center in Brazil.

Providing Reman-related Information

The Komatsu Group has set up "Reman-Net" as a network for Komatsu Reman Centers around the world. The Group is actively using this network to develop Reman operations for reuse and recycling of components at the global level.

IC tags and two-dimensional bar codes are used to manage each item's remanufacturing history, and to track quality and durability information. This important information is reported to the Group, to help develop components with optimal service life.

Future Steps

To further increase the reuse rate of used components the Komatsu Group is reducing the number of disposed parts by:

  • ·Developing parts for remanufacturing, oversized parts, etc
  • ·Developing recycling-related technologies (assessment and measurement for reuse, manufacturing worn-out parts, high-pressure cleaning, heat treatment, etc.)
  • to reduce waste components, and thereby further increase reuse and recycling activities.
