Approach to Reduce Environmental Impact
Installation of Boiler Using 100% Waste Cooking Oil
In April 2021, we began using a waste cooking oil boiler at our Tohoku Plant that uses 100% of the waste cooking oil generated at production plants as fuel.
We reduced CO2 emissions by approximately 1,200 tons per year by using vegetable-derived waste cooking oil instead of the traditional heavy oil.

100% reuse of chicken manure (installation of boilers/composting)
Chicken manure collected from the poultry house (YONEKYU OISHII TORI CORP., Tottori and Shizuoka) is 100% recycled. We have installed a boiler that can use chicken manure as fuel, and use the heat source for floor heating in the poultry house to help create a comfortable growing environment for the chickens, and reuse it for hot water used in the factory. We are also working to reduce our environmental impact by composting chicken manure.

Boiler fuel conversion and Installation of solar panels
We have converted our boiler fuel from heavy oil A to LPG at our Hokuriku Plant. We are also working to reduce emissions by installing a roof-mounted solar power generation system at the Rokko Plant.
We will continue to consider expanding these initiatives to other plants to reduce CO2 emissions, and will also consider procuring renewable energy sources.

Installation of a Cogeneration System
We installed a cogeneration system in February 2022 at the ASAKUSA HAM Kanto Plant.
A cogeneration system is an energy-efficient power generation system that generates electricity using city gas as fuel and captures and utilizes the heat emitted.
We anticipate a reduction in CO2 emissions due to the reduced operating time of our existing steam boilers, and are considering introducing this system at other plants as well.

Introduction of EV vehicles (electric vehicles)
EVs (electric vehicles) were introduced as part of the Meguro Office company fleet for environmental considerations.

Food Waste Recycling
We operate a food waste recycling activity takes place at the Yonekyu Eco Project Center (Asagiri, Fujinomiya City, Shizuoka Prefecture).
The center recycles food waste from our plants and from subcontractors to produce approximately 500 tons of high-quality fertilizer (Compost Power ) annually.
The fertilizers are used by contract farmers and for various other purposes, reducing our environmental impact.
