Production initiatives

Reducing CO2 Emissions by the Production Division

The Kewpie Group is committed to saving energy by improving the efficiency of production processes and by installing new equipment. We are converting from using Heavy Fuel Oil A to city gas and natural gas, and we are promoting the use of co-generation and solar power. We are also working to reduce CO2 emissions by sharing and developing the outstanding initiatives taken by group plants.

CO2 emission reduction targets of the production division
  • Total year-on-year reduction
  • Emissions per unit of production volume: 1% year-on-year reduction

In fiscal 2019, CO2 emissions from the energy used by Kewpie Group production plants totaled 178,600 tonnes, a 10.8% decrease from the previous year. CO2 emissions per tonne of production (emissions per unit) totaled 220.9 kg, a 5.6% decrease from the previous year. The significant decline in food loss can be attributed to the partial disposal of the salad and delicatessen sector by sale.

CO2 Emissions

Targeted plants: Kewpie Group production plants

Coefficients used in calculating CO2 volume (fixed since fiscal 2013)
Coefficients are from the Enforcement Order for the Act on Promotion of Global Warming Countermeasures (December 2002 revision); Agency for Natural Resources and Energy, “Tables of Standard Calorific Values by Energy Sources,” February 2002; and Ministry of Economy, Trade and Industry and Ministry of the Environment, “Emission Coefficients by Electric Utility Operator,” fiscal 2011 results).

Purchased electricity
0.491kg-CO2/kWh

Heavy Fuel Oil A:2.710kg-CO2 /L

City gas (13A):2.188kg-CO2/m3

LPG:6.007kg-CO2/m3

Utilizing natural refrigerants

By incorporating natural refrigerants when upgrading our refrigeration units, we have eliminated CO2 emissions and fluorocarbon use. We also have introduced natural refrigerants when we retired equipment at our Nakagawara plant (Fuchu, Tokyo) in FY2017 to help achieve our goal of eliminating fluorocarbons.

CO2 emission reductions via natural refrigerants (▲530 tーCO2 planned)
  • FY2018 ▲940 tーCO2
  • FY2019 ▲947 tーCO2

In the Kewpie Group, we introduce energy efficient equipment including freezers and work to optimize our equipment.

* This initiative receives assistance through the Ministry of the Environment’s “Project to promote energy efficient commercial refrigeration and air conditioning for the creation of a CFC-free society.”

Conserving Energy by the Production Division

The Kewpie Group is promoting energy conservation in a number of ways. We are visualizing energy use at production facilities by installing energy measurement devices at each stage of production. We are also improving the operation of equipment, performing comprehensive maintenance, and are installing energy saving equipment at all group companies.

In fiscal 2019, energy use at Kewpie Group production plants was equivalent to 3,508,000 GJ, a decrease of 10.5% from the previous year. Energy use per 1-tonne of production Volume (usage intensity) was equivalent to 4.34 GJ, a decrease of 5.2% from the previous year. The significant decline in food loss can be attributed to the partial disposal of the salad and delicatessen sector by sale.

Making Use of Renewable Energy

The Kewpie Group began to promote renewable energy by installing a solar power system at the K.R.S. Corporation’s Matsudo sales office and Itami third sales office in March 2013. This system is now installed at 10 facilities, and it generates 4,500 MWh in electricity, about 2% of the electricity used by group production divisions (as of November 2019). At Aohata Corporation, a heat exchange cooling system using underground cold heat has been in operation since 2005.

Solar power generation at manufacturing plant in Thailand

We continue to introduce solar power systems both domestically and overseas.
Domestically, the Shunsai Deli Co. Ltd. Akishima site began its on-site solar power generation in April 2020, the 2nd site to implement solar power generation after the Kewpie Goka plant. Overseas, we have expanded the solar power system at our Thailand manufacturing plant so that it can generate approximately 2MW of renewable energy.
We continue to make progress converting the Kewpie Group to renewable energy.
