Reducing Environmental Impact


Reducing Environmental Impact

In fiscal 2018, the Nissui Group formulated its medium- to long-term targets by setting CO2 emissions, water use and waste production as three important benchmarks, and has since been making efforts to reduce environmental impact. In fiscal 2021, we formulated our long-term vision (i.e., Good Foods 2030) and mid-term business plan (i.e., Good Foods Recipe1) and set even more ambitious targets for reducing environmental impact, among others.

Long-term vision Mid-term business plan

Fiscal 2022 is the first fiscal year for Good Foods 2030 and Good Foods Recipe1 . As results relating to the new targets will be disclosed in fiscal 2023, the results relating to previously-announced targets are shown for now.

CO2 Emissions

Reduction of CO2 Emissions in Cold Storage Warehouses: Switching to Natural Refrigerants

The Nissui Group is switching the refrigerants used in cold storage warehouses at its production plants and logistics centers to natural refrigerants with low environmental impact (such as CO2 and NH3). Our track record in replacing refrigerants with natural refrigerants and newly introducing natural refrigerants with the use of government subsidy projects is as follows.

  Number of introduced cases  Example of introducing business location Example of subsidy name Example of natural refrigerant type CO2 emissions reduced 
FY2020 6 cases Himeji General Plant (Nissui), etc. FY2020 Subsidies for CO2 Emission Reduction Countermeasures Projects
"Project to Accelerate Introduction of Energy-saving Natural Refrigerant Equipment for Early Realization of HFC-free/Low Carbon Society"
CO2/NH3 1,401
FY2021 3 cases Nissui Logistics Corporation, etc. FY2021 Subsidies for CO2 Emission Reduction Countermeasures Projects

Reduction of CO2 Emissions during Transportation

Carry Net Co., Ltd., which is one of the Nissui Group companies in Japan, is a transportation company with eleven sales offices (excluding the head office) across Japan. Its role is to deliver Nissui products to our business partners on a daily basis. Centering on frozen transport, Carry Net is capable of executing transportation adapted to all temperature zones such as cold and ambient temperatures. It not only performs deliveries in the respective local areas of its sales offices but also carries out wide-area transportation across Japan by utilizing its fleet of vehicles as well as networks based on its partnership with collaborating companies.

[Modal Shift (Utilization of ferries and other non-international coastal trading vessels)]

Carry Net is making efforts to reduce CO2 emissions by performing transportation utilizing ferries.
In FY2021, Carry Net's modal shift (converting part of transportation operations to marine transportation using RORO (“Roll-on, Roll-off”) vessels mainly used for freight transportation owned by partner company, MOL Ferry Co., Ltd.) was recognized by the Ministry of Land, Infrastructure, Transport and Tourism under the Act on Advancement of Integration and Streamlining of Distribution Business, which promotes the integration and efficiency of distribution operations. By reducing the distance of land transportation between Kawasaki and Fukuoka from approx. 1,100 km to approx. 120 km, CO2 emissions can be reduced by 71%. In addition, the time required for a driver to be on the road can be reduced by 87.4%.

[Trailer Transportation]

Carry Net executes mass transportation based on trailer transportation (Note 1) between frozen food plant depots. Carry Net also conducts switch operation (Note 2), which helps improve drivers' working environment as well.

(Note 1) Trailer transportation: Capable of loading approx. 1.3 times more cargo than large vehicles. Can load 40 sheet pallets.
(Note 2) Switch operation: Operation by switching the head and the trailer.

[Utilization of Double-Deck Trucks]

Double-deck trucks make it possible to realize diversified transportation through partitioning (e.g., frozen temperature in the front compartment and chilled or ambient temperature in the rear compartment), and optimize the inside of the vehicle according to customers' needs. For the transportation of products in different temperature zones, multiple vehicles had to be organized by temperature zone in the case of conventional trucks, whereas with double-deck trucks, the number of vehicles can be reduced by transporting them at once.

Reduction of CO2 Emissions at Production Plant

[Switching to Green Energy (Flatfish Ltd.)]

Flatfish Ltd. (UK), which is one of the Nissui Group companies outside of Japan, is engaged in the manufacture and sale of fresh fish and processed seafood products. In 2021, Flatfish changed its electricity supplier in order to reduce CO2 emissions from its business locations. Electricity shared by the new supplier is generated entirely from renewable energy sources, namely, hydraulic power, solar power and wind power. Such change in the supplier translates into a reduction of 266t-CO2/year.

Reduction of CO2 Emissions through Eco-Cars

[Introduction of Eco-Cars into Company Sales Fleet]

Nissui has been promoting the introduction of hybrid vehicles, PHVs and EVs in its sales fleet in an effort to reduce CO2 emissions. Nissui's targets and results of the introduction of eco-cars as a percentage of its sales fleet are as follows.

  Target Results
Medium-term targets (to FY2024) Long-term targets (to FY2030) FY2020 FY2021
Introduction of hybrid vehicles 100% 100% 89.7% 89.7%
Introduction of PHVs/EVs (Note) - 10% 0% 0%

Scope: Nippon Suisan Kaisha, Ltd. (Nissui)

(Note) PHV: Acronym for Plug-in Hybrid Vehicle. PHV is a hybrid vehicle that can be charged by using an external power source and has a large battery capacity. Even when charged by electricity alone, PHV is capable of traveling longer distances than conventional hybrid vehicles.
EV: Acronym for Electric Vehicle.

Calculating CO2 Emissions for the Entire Supply Chain (Scope 3)

It is becoming increasingly necessary to calculate and reduce greenhouse gas emissions not only for the Nissui Group's own operations, but also in the entire supply chain. Nissui has calculated the amount of CO2 emissions from upstream and downstream in its supply chain, otherwise known as Scope 3 (Note) emissions, which refers to emissions other than those generated by fuel combustion or the consumption of electricity during production.

(Note) Scope 3 emissions: Other indirect emissions not covered by Scope 1 and Scope 2 (emissions from other companies related to the company's business activities).

Water Use

Water Usage

Reduction of Water Use in Production Plant

[Recycling of Used Water at a Plant (Thai Delmar Co., Ltd.)]

Thai Delmar Co., Ltd. (Thailand), which is one of the Nissui Group companies outside of Japan, is engaged in the manufacture of frozen foods. It is necessary to keep the walls of the plant’s building clean by periodically washing them with water. Furthermore, the land owned by Thai Delmar that is expected to be used in the future has been turfed, the maintenance of which also requires water.
In 2021, a team of engineers looked into recycling the water used at Thai Delmar. After verifying that the water released from the effluent treatment facility above a certain water quality level can be produced, maintained and managed on an ongoing basis, a water recycling pipeline was installed to actually release such water. Thai Delmar has been able to recycle 6% of annual water supply usage in terms of weight by using such water for cleaning its building and watering the turf.
