Four plants in the Group have switched their boiler fuels from heavy fuel oil to liquefied natural gas (LNG) or liquefied petroleum gas (LPG), which emit less CO₂. Fuel conversion is also planned for two additional plants.The five plants that have been established in recent years do not use heavy fuel oil, instead using electricity and gas as energy sources to reduce CO₂ emissions.

Boilers are mainly fueled by heavy fuel oil and gas, but six plants in our Group have introduced waste oil boilers that use animal and vegetable oil from the food production process to reduce CO₂ emissions.
We are considering installing waste oil boilers at multiple other plants in addition to the existing plants.

Oakey Beef Exports Pty. Ltd., which processes cattle in Australia, installed a biogas plant in April 2015 to extract methane gas generated from factory wastewater and use it as a source of energy.
Through this actions, we are working to reduce the use of natural gas and CO₂ emissions.

Nipponham Processed Foods Ltd.’s Kanto Plant, which is engaged in the manufacture of processed foods, is reducing the amount of electricity it uses by replacing its refrigerators.
They are also working to improve the efficiency of electricity use by installing energy-saving equipment and reviewing operating hours.

At Nippon Pure Food, Inc.’s Nishinomiya Plant, which engages in the manufacture of processed meat, boilers have been replaced with high-efficiency boilers, and the tank piping has been modified to take advantage of previously unused heat in order to raise the boilers’ water supply temperature, reducing fuel consumption.

Nippon White Farm Co., Ltd., which handles production, treatment, and processing of chicken, uses boilers to heat its poultry houses.
Measures are being considered to reduce CO₂ emissions by introducing high-efficiency boilers and gas boilers on a trial basis.

Five plants in our Group use cogeneration systems.
A cogeneration system is equipment that generates electricity using gas, and then uses the heat generated during power generation to create steam and hot water, thereby using energy efficiently.

We installed waste heat recovery compressors at several plants in the Group.
Until now, the heat generated when compressing air was discarded, but by using this heat to create hot water and feed the boiler, the amount of fuel used for the boiler will be reduced.

Turbo blowers have been installed in wastewater treatment facilities at several of the Group’s plants, which are more efficient and save energy compared to the previous blowers.

Heat pumps have been installed to heat some of the poultry houses at Nippon White Farm Co., Ltd.’s Shiretoko Office.
Heat pumps are a technology that collects and uses heat in the air, requiring little energy.
We have installed a single heat pump to verify whether it will reduce energy use and CO₂ emissions throughout the year compared to a conventional hot water boiler.

We are using air leak detectors, which use ultrasonic waves to show where compressed air is leaking, and are repairing air leaks discovered at our plants.
Eliminating air leaks leads to a reduction in the extra energy consumed to create compressed air.

Nippon Dairy Net Co., Ltd. which handles the distribution of ham, sausages, and other processed foods, is reviewing loading efficiency and transport routes and is working to raise transport efficiency among the Group manufacturing plants and centers.
