Production-related Input and Output (Non-consolidated MGC and Domestic MGC Group)

Primary production-related inputs and outputs for the non-consolidated MGC and domestic MGC Group in fiscal 2019 were as follows:

Environmental Preservation Investments (Non-consolidated)

In fiscal 2015, MGC began undertaking environmental preservation investments.
These investments include investment items that, although they may be very effective in reducing environmental loads, may be less likely to be adopted due to long payback periods or for other reasons, as well as investment items that lead to preservation of biodiversity, recruited through proposals from the various MGC sites. A secretariat consisting of the Environment, Safety and Quality Assurance Division and the Production Technology Division at corporate headquarters then select the items to implement and secure the required budget, before executing the investment.

For example, by replacing mercury lamps and fluorescent lights with LED bulbs, it is possible to both save energy and reduce mercury-containing equipment. Replacing air conditioning equipment with energy-saving models has the dual effect of conserving energy and reducing CFCs (thus preventing destruction of the ozone layer). Further, replacing the equipment with air conditioners that do not use freon as a refrigerant can obtain the additional effect of reducing greenhouse gases.

In fiscal 2019, MGC replaced mercury lamps with LED bulbs in lighting used in its buildings and along roads on their premises, upgraded air conditioning equipment, converted cooling tower fans to inverter controlled, and took other measures. These steps had the effect of reducing GHGs by about 187 t-CO2/year on a pro forma basis.

In addition, solar power generating facilities were installed at the Niigata Science-Engineering-Quality (N-SEQ) Building newly established at the Niigata Research Laboratory using fiscal 2018 environment preservation investment with construction completed in August 2020.
MGC will continue to promote the use of renewable energy in the future.
