Promoting Recycling  Effective Utilization of Resources in Manufacturing Operations (Waste)

Strong Waste Liquid Disposal Equipment

Strong Waste Liquid Disposal Equipment



In tandem with reducing the amount of waste produced during manufacturing operations, Komatsu engages in "zero emissions" activities to use waste materials as resources. Starting in FY2011, Komatsu set new medium-term goals for our recycling rate and for the amount of waste generated per unit, and we are working toward those goals. In an effort to attain zero emissions, Komatsu raised the target recycling rate which was 99.5% or greater by FY2015. Our recycling rate reached 99.6% in FY2012, achieving the mid-term goal earlier than planned for the second year in a row.

Komatsu had projected cuts in the amount of waste materials generated per unit of manufacturing value in FY2015 of 20% or greater, compared to the FY2005 level. As a result of strict adherence to separated-waste collection and increased conversion of waste materials to resources, the amount of waste materials generated per unit has been trimmed by 41.3%, compared to the FY2005 level. In particular, the Oyama Plant implemented strong liquid waste disposal equipment, in an effort to greatly reduce liquid waste, and halved its generated waste in comparison to the previous year. Komatsu aims to continue its effective separated waste collection policy to achieve its medium-term goals.
