Management of other chemical substances

Management of Pollutant Release and Transfer Register (PRTR) Substances

When the amount of chlorodifluoromethane (HCFC-22) used as a refrigerant exceeds 1ton, we report it under the PRTR system.

  • * The laws concerning the Pollutant Release and Transfer Register refer to the collection and publication of data related to the release into the environment of chemicals, from any source, which could possibly adversely affect the lives, growth, or development of humans, animals, or plants.

Management of PCBs

Polychlorinated biphenyls (PCBs), a group of man-made compounds, were previously used as insulating oil in transformers, but their use was banned in the 1970s, after their toxicity became apparent.

In Japan, equipment that has been confirmed to contain PCBs is being appropriately stored in compliance with standards set by law. Currently, disposal is being carried out systematically, based on the capacity of the nation's five government-run PCB disposal plants.

Use and management of CFCs

Chlorofluorocarbons (CFCs) are said to be among the substances destroying the ozone layer. Their production is being phased out, and management regulations have been put into effect in sequences, starting with freon, which is the most destructive of the ozone layer.

The Nichirei Group uses freon as a refrigerant in the cooling facilities at its food plants and logistics centers. Although appropriate equipment management ensures that the refrigerant, which circulates within sealed cooling equipment, does not leak, we dispose of it as required by law when major equipment repairs are carried out.

Meanwhile, the fact that freon is one of the gases that causes global warming has also become an issue. Since the CO2 of the energy sources used for cooling equipment are also linked to global warming, we are determining the refrigerant we prefer in new equipment based on its energy-saving properties.

Management of asbestos

The asbestos that was found to have been sprayed on the underside of the roof, and which had the possibility of spreading, was removed and disposed of during an inspection in FY2006. In addition, when demolishing office buildings that have been closed, we do another survey and take legally compliant and appropriate steps to dispose of any building materials containing asbestos.

Management of contaminated soil

In addition to fulfilling the appropriate disclosure requirements when selling, buying, or renting land, we do evaluations of soil contamination and carry out the appropriate management.
