Waste

KOGAS strives to minimize the waste generated from business activities such as natural gas production, supply, and construction work; and processes such waste separately according to type and usage. In addition, when we place construction orders, we require our contractors to use recycled aggregates to facilitate the reuse of resources. Our company-wide resource-saving efforts include prohibiting the use of disposable products in the office, and imposing an environmental charge on using them at the in-house cafe
