Reduction of CO2 Emissions

CO₂ Emissions

Renewable Energy

We are expanding the use of renewable energy sources across the Group. We explore every feasible opportunity to install solar power generation facilities along with the possibility of entering PPAs (Note).

(Note) PPA: Power Purchase Agreement. A company enters into an agreement to purchase electricity derived from renewable sources from a supplier rather that investing its own capital.

Reduction/Control of CO₂ Emissions at Production Plant

[Control Methane Emissions through Biomass Electricity Generation (Nissui Hachioji General Plant)]

Nissui’s Hachioji General Plant produces frozen foods, surimi-based products, and seasonings. In FY2018, the plant significantly enhanced its wastewater treatment system by introducing an anaerobic ozone treatment facility to complement the existing enzymatic wastewater treatment facility. However, the wastewater treatment process at this facility resulted in the production of methane gas, which has a much greater greenhouse effect than CO₂. To counter this, Nissui embarked on a biomass electricity generation initiative, capturing the methane produced in the treatment process and using it to fuel power generators. This innovative step not only adds value to the wastewater treatment process, but also plays a critical role in preventing global warming by reducing methane emissions into the atmosphere. This proactive approach is expected to reduce methane emissions by an estimated 2,380 t-CO₂ equivalent annually.

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 plan between Kawasaki and Fukuoka was approved as a plan for advancement of integration and streamlining of distribution business under the provisions of the Act on Advancement of Integration and Streamlining of Distribution Business of the Ministry of Land, Infrastructure, Transport and Tourism. This plan involves shifting part of our truck transportation to marine transportation using RORO vessels (Note 1) that primarily transport cargo, operated by our partner MOL Ferry Co., Ltd. This enables us to reduce ground transportation distance from approx. 1,100 km to approx. 120 km and CO₂ emissions by 71%. In addition, the time required for a driver to be on the road can be reduced by 87.4%.

(Note 1) RORO vessels (Roll-on/Roll-off ship): A cargo ship with a deck for vehicles, designed to carry loaded trucks and trailers as they are.
(Note 2): Since 2021, the calculation method has been changed under the guidance of the Transport Bureau.

[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.

[Introduction of COOL Hybrid]

Three large COOL Hybrid trucks (manufactured by Hino Motors) are scheduled to be introduced in June 2024. Electric energy is stored in batteries and converted into energy for refrigeration and driving, thereby reducing CO₂ emissions from large vehicles.

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 (Note) 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.

(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.

Participating in the Development and Field Testing of an Aquaculture Feed Boat that Uses Hydrogen Fuel Cells

The “Development and Field Testing of an Aquaculture Feed Boat Using Hydrogen Fuel Cells for Use in Fish-farming” project, in which Nissui Group company Kurose Suisan Co., Ltd. has been participating, has been chosen by Japan’s Fisheries Agency as an “Aquaculture Synergy Business Creation Project.” This project has been undertaken by a consortium of three participants: the Fishing Boat and System Engineering Association of Japan (acting as project lead), the Japan Fisheries Research and Education Agency (FRA), and Kurose Suisan. To promote the transition toward carbon-neutral aquaculture that will be both a high-growth industry and decarbonized, the project aims to bring about a switch away from using fossil fuels to power the feed boats used in aquaculture, toward using non-fossil fuel power sources such as hydrogen, through the development, building and field testing of a feed boat equipped with hydrogen fuel cells. This represents an important initiative in terms of building a sustainable fisheries sector in which greenhouse gas emissions from boats are reduced, and the Nissui Group will continue to proactively undertaken development of this type of new technology in the future.

[Project Objectives and Project Content]

• Development of an aquaculture feed boat that uses hydrogen fuel cells as the motive power source, in accordance with the “Hydrogen Fuel Cell Boat Safety Guidelines,” based on energy simulations using hydrogen fuel cell equipped fishing boats, and using a boat design in which equipment selection and layout is tailored to ensure that the boat can properly perform aquaculture operations such as feeding fish.
• It is intended to build a 16-ton aquaculture feed boat with propulsion output of 250 kW for use in field testing.
• Field testing will be performed over a period of approximately 90 days to examine the practicality of the design, in terms of whether the boat is able to maneuver and perform feeding operations without problems, along with the collection of data relating to endurance, speed, maximum period of continuous operation, etc., and comparison of the economic efficiency of the design in relation to existing boats, so as to identify and collate potential issues in the future deployment of hydrogen fuel cell powered boats.

The type of feed boat that is currently in use

Nissui has been making group-wide efforts to review the use of refrigerants. Besides setting a target of reducing the use of CFCs and HCFCs to zero by FY2030, Nissui has also adopted a policy of ensuring that, for the main types of freezing and refrigeration equipment used by Nissui itself, 100% of newly-adopted equipment will use only natural refrigerants. Some examples of these, such as replacement with natural refrigerants utilizing government subsidized projects and new introduction of natural refrigerants, are as follows.
