Addressing soil and groundwater contamination

Komatsu has established guidelines for testing soil and groundwater, inspects any business unit that is scheduled to be sold, closed, or removed pursuant to laws and regulations, and takes purification measures upon confirmation by local authorities if contamination is discovered.
We voluntarily investigate business units in operation in order to test for contamination stemming from VOCs in cleaning solvents, etc. used in the past.
We have been surveying soil and groundwater for VOC contamination at domestic business units since 2005, and have implemented countermeasures at any sites that have been found to be contaminated. We use methods that facilitate the cleaning process in the shortest period of time possible.
We will continue to thoroughly clean-up and regularly monitor groundwater at site boundaries to ensure that there is no outflow of groundwater that has exceeded the standard outside the premises.

Managing PCB (Polychlorinated Biphenyl) waste

Komatsu stores and disposes of PCB-containing waste (such as transformers and fluorescent stabilizers) in accordance with the "Act on Special Measures concerning Promotion of Proper Treatment of PCB Wastes" and the "Waste Management and Public Cleansing Law".
We intend to continue our appropriate treatment of PCB waste, including low-concentration PCB waste, according to our plan.

Reducing VOC Emissions

The majority of VOC emissions are from VOCs contained in paint such as xylene and ethyl benzene.
Although emissions in FY2021 increased slightly compared to the previous year due to the rise in production volume, we successfully maintained a 50% reduction in the amount of VOC emissions per unit of manufacturing value (compared to FY2005).

Holding regional environment meetings

At overseas business units, employees in charge of the environment and safety in each region have gathered to hold regional meetings since FY 2019. By exchanging information of and discussing common issues in the region, they aim to improve compliance and the level of the environmental impact reduction activities at each business unit. Meetings in FY 2021 were held in Latin America, Europe, Southeast Asia, Oceania and China, with the exception of North America (Cancelled due to a coronavirus outbreak.) In these regions, meetings were held online due to COVID-19. These meetings were all attended by many participants who reported on their companies’ environmental activities. Through activities like this, we would like to further revitalize the environmental activities of the Komatsu Group.
