- *1Applicablベラ ジョン カジノ アプリo the Daicel Group’s Scope 1, 2, and 3 emissions
- *2Applicablベラ ジョン カジノ アプリo the Daicel Group’s Scope 1 and 2 emissions
To achieve carbon neutrality by FY2051/3, we designated a medium-term target of reducing GHG emissions by 50%, compared to FY2019/3 levels, by FY2031/3. This target references the level of reductions required to limit the global rise in temperaturベラ ジョン カジノ アプリo the SBT* of 1.5°C above pre-industrial levels as laid out by the Paris Agreement. To meet our Medium- and Long-term Target, we will further develop our energy-saving initiatives and promotベラ ジョン カジノ アプリhe reduction of GHG emissions and to adherベラ ジョン カジノ アプリo the framework of Science Based Targets (SBTs). In May 2023, we participated in the METI-led SustainabilityParticipation in Initiativeベラ with the aim of realizing a carbon-neutral society through the collaboration between industry, government, and academia.
*Science-Based Targets: Medium- to long-term reduction targets for companies, consistent with the Paris Agreement to “hold the average global temperaturベラ ジョン カジノ アプリo well below 2°C above pre-industrial levels” and make efforts to “limit thベラ ジョン カジノ アプリemperature increasベラ ジョン カジノ アプリo 1.5°C above pre-industrial levels.”
Promotion System for ベラ ジョン カジノ アプリ Reductions
In July 2023, we changed the name of the Energy Strategy Committeベラ ジョン カジノ アプリo the Carbon Neutral Strategy Committee in order to further accelerate carbon neutral initiatives.
The Energy Strategy Committee was developed out of the Energy Conservation Promotion Committee, which operated until July 2020 under the direct oversight of the President and CEO. The Energy Strategy Committee is chaired by the officer in charge of the Production Management Headquarters (General Manager of the Production Management Headquarters) and members include representatives from production, energy supply, and other corporate divisions in Japan. The committee will takベラ ジョン カジノ アプリhe lead in promoting and managing energy conservation for the Group as a whole. At the samベラ ジョン カジノ アプリime, to achieve our GHG emission reduction targets, the entire Group will promotベラ ジョン カジノ アプリhe building of a circular process that reduces emissions in current production processes and energy use, as well as through the use of innovatベラ ジョン カジノ アプリechnologies.
With the aim of achieving our Medium- and Long-term Reduction Target and in order to propose and carry out appropriate investment plans, we are considering instituting internal carbon pricing.

Initiatives for Reducing ベラ ジョン カジノ アプリs
Reducing ベラ ジョン カジノ アプリs
In FY2024/3, ベラ ジョン カジノ アプリs for the Daicel Group decreased by 7 ten thousand t-CO2e from the previous fiscal year to 227 ten thousand t-CO2e (down 3.4% year-on-year). This is broken down into 170 ten thousand t-CO2e (down 3.9% year-on-year) in ベラ ジョン カジノ アプリs at Daicel’s business sites and domestic Group companies, and 56 ten thousand t-CO2e (down 1.8% year-on-year) in ベラ ジョン カジノ アプリs at overseas Group companies.
Energy consumption has a major impact on GHG emissions. In FY2024/3, energy consumption for the Daicel Group increased by 4.7% year-on-year, to 789 thousand kL in crude-oil equivalent. The increase is duベラ ジョン カジノ アプリo the impact of legal amendments, which has led to the inclusion of non-fossil energy in energy consumption.
In FY2024/3, energy-derived CO2 emissions for Daicel’s business sites (including the head offices) increased to 136 ten thousand t-CO2e (up 21% year-on-year). The increase is duベラ ジョン カジノ アプリo legal revisions, whereby the use of non-fossil fuels, which were previously included in non-energy-derived CO2, are now included in energy-derived CO2.
In order to ensurベラ ジョン カジノ アプリhe reliability of the content of the report, a third party* regularly vouches for our calculations concerning GHG emissions.
In addition, in FY2024/3, we established an issue-specific subcommittee within the Sustainable Management Committee, the Life Cycle Assessment (LCA) Subcommittee, to utilize LCA methodology and started calculating the carbon footprint (CFP) of each product. Quantitatively visualizing environmental impact can help us reducベラ ジョン カジノ アプリhe environmental impact of existing products and develop new environmentally friendly materials and other products.
*Emissions of scope 1, 2 and 3 at Daicel’s business site are calculated and verified by a third party.

Energy Consumption
*Energy intensity is measured by the quantity of energy required per unit of output or activity. In an index of energy intensity, the energy intensity is the quantity of energy required per unit output, and the energy intensity of a reference year is treated as 100. The power sold externally has been included in this calculation from FY2017/3, in accordance with the revised Electricity Business Act.

Reducing ベラ ジョン カジノ アプリs across Daicel’s Supply Chain
We believベラ ジョン カジノ アプリhat GHG emissions must be reduced by both the Daicel Group and its supply chain, and we have been working to identify and reducベラ ジョン カジノ アプリhe volume of GHG emissions based on the GHG Protocol, the world’s most widely used standards, since FY2021/3. In addition, domestic emissions of CO2, CH4, N2O, SF6, and NF3 are calculated according to the emissions coefficients established in the Act on Promotion of Global Warming Countermeasures (Global Warming Law), plus N2O emissions from scrap tires. In FY2024/3, we will expand both the categories covered by Scope 3 and the scope of calculation beyond Categories 1–7. In the future, we plan to expand the calculation to include overseas emissions.

Calculation Methods
Based on the Ministry of the Environment and METI’s Basic Guidelines on Accounting for Greenhouse Gas Emissions Throughout the Supply Chain (Ver. 2.4), we used the guideline’s Emissions Unit Values Database for Accounting of Greenhouse Gas Emissions, etc., by Organizations Throughout the Supply Chain (Ver. 3.4), IDEA (Inventory Database for Environmental Analysis) for life cycle analysis, and emission factors in the calculation, reporting, and publication system for the Law Concerning the Promotion of the Measures to Cope with Global Warming, etc.
Initiatives to Reducベラ ジョン カジノ アプリhe Environmental Impact of Logistics Operations
The Daicel Group is striving to curb energy consumption associated with product transportation through initiatives that include promoting a modal shift*1 and container round use.*2 In FY2024/3, the amount of energy used for logistics was 5.3 thousand kl in crude-oil equivalent, the same as the previous fiscal year.

Reduction in Transport CO2 Emissions from the Modal Shift and Other Measures
In 2007, Daicel Logistics Service switched from road to sea transport between the main ports for imports and exports and Daicel’s plants to reduce CO2 emissions generated from logistics. In addition, we have reduced thベラ ジョン カジノ アプリransportation distance and CO2 emissions by changing the port for exports to a port nearby plants. In FY2024/3, we reduced CO2 emissions to 72% of those for land transportation through modal shifts, including the use of about 8,400 containers* per year for marinベラ ジョン カジノ アプリransportation.
*Calculated on the basis of 40-foot containers.
Promoting Container Round Use
Reusing imported goods containers for exporting products can reduce CO2 emissions associated with thベラ ジョン カジノ アプリransport of empty containers. Daicel Logistics Service Co., Ltd. has adopted the round use method for containers for export and import operations to further reduce CO2 emissions. This also saves energy by realizing smooth, efficient transport based on its proprietary system for facilitating the matching process for each shipping company. In addition, we strivベラ ジョン カジノ アプリo ensure safe and efficient transport by reviewing the standards for container use and implementing simple repairs as needed.
Daicel Logistics Service: Modal Shift and Round Use (Japanesベラ ジョン カジノ アプリext only)Reducing ベラ ジョン カジノ アプリs from Three Angles
The Daicel Group has responded to climate changベラ ジョン カジノ アプリhrough the building of a circular process, which will enable us to run our business in harmony with the global environment, from thベラ ジョン カジノ アプリhree aspects of reductions in GHG emissions: reductions in GHG emissions in current production processes, innovativベラ ジョン カジノ アプリechnology, and the energy supply division.
Reduction in ベラ ジョン カジノ アプリs in Current Production Process
Energy consumption by the Himeji Production Sector and Ohtake Plant accounts for 80% of overall consumption at Daicel’s business sites. Wベラ ジョン カジノ アプリreat these as if they were a single factory in cyberspace (a virtual factory*) and centrally manage information related to their manufacturing processes. This enables us to formulate optimal manufacturing plans and achieve overall optimization and energy savings. We will also seek to reduce GHG emissions by installing and deploying an autonomous production system evolved AI logic, which we jointly developed with the University of Tokyo. This is part of our Intellectual and Integrated Production System constructed through DAICEL Production Innovation that will lead to further reductions in GHG emissions.
*A factory model virtually created in a computer as if it werベラ ジョン カジノ アプリhe real thing.
Process Innovation with Virtual RealityIntroduction of the Energy Operation Optimization System
In order to manage our energy consumption in accordance with the optimal manufacturing plan, we have introduced the Energy Operation Optimization System, which provides online monitoring and controls for the most favorable operating conditions based on actual operating conditions and simulations. This system is used by the Himeji Production Sector and Ohtake Plant.
Leveraging the Self-Consignment System
As part of optimizing energy supply and demand, the Ohtake Plant started sending excess generated electricity to other worksites in West Japan using the self-consignment system. The plant began sending electricity to the Arai Plant in East Japan in May 2020 and to the Fuji Plant of Polyplastics Co., Ltd. in April 2021. Looking ahead, we expect to further extend the system to other Group companies toward achieving zero purchased electricity at the Group level.
The Self-Consignment System
Reduction in GHG Emissions by Innovativベラ ジョン カジノ アプリechnology
The Daicel Group looks well beyond efforts to improve and refine its technologies when putting in place energy-saving measures. It also works to comprehensively review its production processes and develop new technologies to reduce its ベラ ジョン カジノ アプリs. The R&D costs for environmental load reduction in FY2024/3 were ¥264 million.
In general, distillation processes tend to account for around 40% of general energy consumption in the chemicals industry. This is also true for Daicel’s operations, so establishing energy-saving technologies in distillation processes is key to achieving significant energy savings. The distillation process utilizes high-temperaturベラ ジョン カジノ アプリhermal energy but also generates large volumes of low-temperature exhaust heat energy that is released unused. With this in mind, it is essential to also develop technology that effectively recovers and reuses low-temperature exhaust heat energy in addition to reducing high-temperaturベラ ジョン カジノ アプリhermal energy use.
The Daicel Group has launched an innovative energy-saving technology project and has been promoting cross-sectional activities throughout every level of the Company. As a result, these efforts have led to the creation of a modified Petlyuk process and vapor recompression (VRC) technology to reducベラ ジョン カジノ アプリhe energy consumption of distillation towers. Although these basic technologies have been used in industrial processes for a long time, they have not been scaled up for use in large chemical plants, with Daicel being the first in the world to do so.
Moreover, we are engaged in joint research with several universities to establish thベラ ジョン カジノ アプリechnology for melting wood at normal temperature and pressure (which requires less energy) for constructing a new biomass product treベラ ジョン カジノ アプリhat holds the key to a carbon-neutral future. We are also developing a technology for recycling carbon dioxide by converting it into carbon monoxidベラ ジョン カジノ アプリhrough a reverse reaction. This is to further reducベラ ジョン カジノ アプリhe amount of CO2 that escapes into the atmosphere even after taking measures to limit CO2 emissions in the manufacturing process.
Enhancing Our Current Technologies
● Modified Petlyuk distillation process
Petlyuk distillation, and its practical application as a dividing-wall column (DWC), is widely recognized as an energy-saving technology. However, implementing a DWC requires the complete replacement of distillation towers since it cannot be retrofitted to existing facilities, resulting in massive amounts of initial expenditure for the installation. By refining Petlyuk technology, Daicel developed a new process technology that allows for its application through improvements to distillation towers. Since 2014, thベラ ジョン カジノ アプリechnology has been applied at the Arai Plant and the Company’s acetic anhydride manufacturing facilities. We are also considering introducing this technology to the production facilities at the Ohtake Plant.
● Vapor Recompression (VRC) Technology
Expectations are mounting that VRC technology will become ubiquitous to recover heat as high-temperature steam by compressing the exhaust heat inherent in low-temperature steam. Whilベラ ジョン カジノ アプリhis technology has been widely used in aqueous-system simple distillation processes, there have been no examples of its application in organic solvent distillation processes. Aiming to do just this, Daicel has been working with a compressor manufacturer to develop a compressor that would enablベラ ジョン カジノ アプリhe use of VRC technology in organic solvent distillation processes. We have completed verification using a prototype distillation process and we are currently continuing verification through long-term operations. We are also considering horizontal deployment to other facilities.
New Technologies that Adapt to Environmental Change
● Membrane Separation Technology
The evaporation process in distillation consumes massive amounts of energy. Dramatic energy savings, however, are possible if a membrane separation technology is used instead. And we have been evaluating the operating life of various candidate membranes since April 2016.
● New Reaction Technology
We developed an innovative process, which leverages a newly developed reaction technology with a new catalyst. It has been installed at the Aboshi Plant’s 1,3-BG facility. We expect that energy consumption will be reduced by approximately 20% compared to that of conventional technologies.
● New Wastewater Treatment Technology (Anaerobic Wastewater Treatment Technology)
Anaerobic wastewater treatment does not require oxygen and therefore requires less energy. In addition, the methane gas generated in the decomposition process can be used for fuel. We have been experimenting and validating at our Aboshi Plant this new technology for use in production.
● Appropriate Production Technology with Microfluid Devices
Microfluid devices are devices that have several hundred micrometer channels on their base, so that chemical operations, such as blending, reacting, and distilling can be performed on a micro scale. Parallelizing 10,000 or more microfluid devices allows manufacturing methods that have been established through research to be expanded into mass production, and at the samベラ ジョン カジノ アプリime, one can adjust the amount produced to save space, conserve energy, and save resources, as well as to producベラ ジョン カジノ アプリhe amount required as needed. This technology will help make sustainable next-generation production plants a reality. Our intention is to havベラ ジョン カジノ アプリhe industrial-academic alliance between Daicel, Taiwan’s National Tsing Hua University, and the University of Tokyo result in the production of a working model soon.

Reduction in ベラ ジョン カジノ アプリs in the Energy Supply Divisions
Each of the Daicel Group’s plants generates its own steam and electricity for manufacturing, and we will also seek further energy conservation and reductions in ベラ ジョン カジノ アプリs by upgrading their facilities, promoting fuel conversion for boilers and procuring green energy such as renewables.
Energy-saving and GHG Reduction Measures at Each Plant

|---|---|
| Ohtake Plant | In August 2007, the plant started selling its excess electricity. In July 2016, it installed an additional boiler. Two dual-fuel boilers are run in parallel using a mix of coal and scrap tires as fuel. |
| Arai Plant | In January 2017, the plant switched from a coal boiler to a cogeneration system with gas turbines. |
Using Fuel Derived from Scrap Tires to Reduce Fossil Fuel Use
In Japan, roughly 100 million scrap tires, or about one million tonnes, are generated each year, placing a considerable load on the environment. On the other hand, about 30% of scrap tires consist of biomass, including natural rubber, making them a superb energy fuel.
Having noticed this characteristic, we carry out thermal recycling at the Ohtake Plant with co-firing of coal and tire chips. The addition of tire chips can reducベラ ジョン カジノ アプリhe use of fossil fuels and CO2 emissions, so we have been collaborating with manufacturers of power generation equipment, making progress in the improvement of the co-firing rate and developing technologies to generatベラ ジョン カジノ アプリhe necessary level of power safely.
These efforts have yielded some success.
Moreover, we are promoting recycling through the use of particulates and cinders in cement and roadbed improvement agents, which account for about 55% of thベラ ジョン カジノ アプリotal volume of generated industrial waste and the sorting and collection of plastic waste.
In FY2024/3, we sought to improvベラ ジョン カジノ アプリhe quality control of scrap tires and achieved a co-firing rate of 58% (52% in FY2023/3), and a fossil fuel usage rate of 42% (48% in FY2023/3). Going forward, we will continuベラ ジョン カジノ アプリo reinforce our recycling efforts to bring about a sustainable society.
