Environmental Impact and Resource Reduction, and Climate Change Countermeasures / Climate Change Countermeasures

1. Energy Consumption

JSR's Responsible Care Committee adopted a medium-term Independent Environmental Preservation Plan. This plan contains per-unit targets for energy reduction, which serve as measures to help prevent global warming. In order to reach these targets, JSR is engaged in E-100 Plus project activities targeted at reducing energy and resource use. However, we were unable to meet our per-unit energy reduction targets in FY2016 due to production decreases and other factors. JSR remains committed to energy conservation activities and will continue to work toward reducing energy consumption.

(1) Energy Reduction Targets

  • 1. The annual per-unit energy consumption was reduced by approximately 1% based on standards created in FY1999.
    (Independent standard based on regulations concerning the rational use of energy) (This level has been maintained and managed since FY2013)
  • 2. Improvements in average per-unit energy consumption in the most recent 4-year period (from FY2017)

(2) Energy Consumption (Crude Oil Equivalent)*1 and Per-unit Index*2

Energy Consumption (Crude Oil Equivalent) *1 and Per-unit Index *2

2. Initiatives to Reduce Greenhouse Gases

With increasing moves in recent years by businesses to manage greenhouse gases indirectly emitted from their supply chains and disclose their emissions at the global level, JSR has launched initiatives based on the Basic Guidelines on Accounting for Greenhouse Gas Emissions Throughout the Supply Chain issued by Ministry of the Environment, Government of Japan.

Scope1 :
Direct greenhouse gas emissions by sources owned or managed by a company or household (use of fuel: factory, heater, private automobile, etc.)
Scope2 :
Indirect emissions from the use of electricity, steam, or heat (use of purchased electricity, etc.)
Scope3 :
Other indirect emissions besides Scope 2.
("Company" includes the procurement of raw materials, employee business trips, subcontracting of waste disposal, etc.
 "Household" includes the purchase of products, travel, subcontracting of waste disposal, etc)

(2) Actions for Scope 1

JSR set a CO2 emission reduction target under the Medium-Term Independent Environmental Preservation Plan and is striving to meet this target through various energy saving activities.

1. CO2 Reduction Targets and Current Emissions

CO2 Emission (JSR's three plants)
CO2 Emission (JSR's three plants)
CO2 Emissions Reduction Target

Reduced the total CO2 emissions from JSR 's three plants by 6% in total compared to FY1991

Review of CO2 reduction targets with regard to the Paris Agreement (FY2017)

In FY2013, JSR established its "System to Reduce Total CO2 Emissions from Three plants by 6% Compared to FY1991" by upgrading its energy-saving technologies through the introduction of fuel conversion at the Kashima Plant (Kashima South Joint Power Corporation) and a sludge dewatering system at the Yokkaichi Plant. In FY2016, JSR successfully reduced CO2 emissions by approximately 9.5% over FY1991 levels to achieve the reduction target. The per-unit index was 65 in FY2016, which represents a continuing decrease in comparison with FY1991 on a scale of 100.

2. Examples of Measures Taken to Reduce CO2 Emissions

Example 1: Introduction of a natural gas-fired turbine cogeneration system

Natural gas-fired turbine cogeneration system (Yokkaichi Plant)

Natural gas-fired turbine cogeneration system (Yokkaichi Plant)

The Yokkaichi Plant installed a natural gas-fired turbine cogeneration system in April 2010. By using natural gas instead of coal, a heavy oil-fired steam boiler and condensing steam turbine system, this new system helped us to cut CO2 emissions by approximately 38,000 tons in FY2016.

Example 2: Introduction of a sludge dryer system that makes sludge combustible

Sludge dryer system (Yokkaichi Plant)

Sludge dryer system (Yokkaichi Plant)

In FY2013 a sludge drying system was adopted at the Yokkaichi Plant in order to dry the sludge generated from its general wastewater treatment facility. Previously, sludge containing a high percentage of water was burned with combustion support fuel (heavy oil); but drying allows us to use the sludge itself as fuel, which in turn allows us to reduce the amount of combustion support fuel we use. This led to a reduction in CO2 emissions of approximately 1,100 tons in FY2016.

(3) Actions for Scope 2

1. Measures to Cut Power Consumption at the Head Office

Power Saving Target for the Head Office

8% reduction compared to the average power consumption from the base years of FY2010 and FY2011

Major Efforts

  • Policy of turning off lights and office equipment such as printers when not in use
  • Implemented the so-called "Cool Biz" dress code.
  • Changed work schedules so that employees begin work and return home earlier than usual two days per week from June to September.
  • Maintained a proper air-conditioned room temperature that achieves a balance between energy savings and operational efficiency.

Power Consumption at the Head Office

Power Consumption at the Head Office

The Tokyo Metropolitan Government requires major tenants of a building occupying 5,000 square meters or more in floor area or consuming six million kWh or more of electricity annually to reduce its CO2 emissions under the Tokyo Metropolitan Ordinance on Environmental Preservation.
Although we are not subject to this obligation, we are promoting energy conservation on our own initiative by voluntarily setting a specific power saving target.
In FY2016, as a result of these efforts, our power consumption decreased by 21% over the average consumption of the base years.

(4) Actions for Scope 3

1. Environmental Measure in Logistics: Improving Transport Efficiency

As part of our environmental efforts in transportation, we have taken systematic steps to reduce our energy use as a designated shipper under the FY2007 amended Energy Conservation Law. We are working to reduce per-unit transport energy by an average of at least 1% per annum by using larger tanker trucks, and by shifting from road to rail and water transport.
In FY2016, as a result of new policies to transport goods and raw materials by railway and ship, modal share improved 1% over the previous fiscal year, which led to a reduction of 1% in per-unit transportation energy over the previous year.

3. E2 InitiativeTM

The JSR Group's "E2 InitiativeTM" is an "environmental value creation" concept that provides clarification on what we need to keep in mind as we manufacture our products and develop our business. It is also used as a concept that allows us to work toward solving problems related to energy, resources, and climate change as we carry out our business activities.

(1) Working to Solve Environmental Issues through the Deployment of E2 InitiativesTM

Because both humans and a large number of other living things share the Earth and its resources, we must make an earnest effort to tackle environmental issues. The JSR Group has adopted its E2 InitiativeTM as a concept to simultaneously reduce its environmental impact and create new business opportunities through environmentally friendly products.
The E2 InitiativeTM is based on "Eco-innovation," which is designed to create business opportunities based on the environment, and Energy Management, which is focused on reducing CO2 emissions. It is a concept that allows us to create value both in active and passive ways. As we have shifted our concept of value from the conventional two approaches of differentiation and cost, our new concept of environmental performance has become essential.
By using Lifecycle Assessment (LCA) to evaluate the environmental impact of our products from the design stage in product development to the use of the product, we are working to solve environmental problems throughout business operations.

E2 Initiative TM

(2) LCA & LCI Initiatives

LCA (Life Cycle Assessment) is a method of quantitatively assessing environmental impact throughout the lifecycle of each product, from the materials procurement stage to manufacturing, sales, use, and disposal.

LCA & LCI Initiatives

Implementation of LCA requires that we calculate the amount of resources used when manufacturing a product and the amount of CO2 emissions during all stages of the lifecycle of a product (LCI data).
The entire synthetic rubber industry, including the JSR Group, has engaged in LCI data calculations for representative synthetic rubber products.
The results of these calculations are stored in a database maintained by the Japan Environmental Management Association for Industry LCA Forum. For LCI data of our fine chemical products, we keep track of the amount of CO2 produced during the production.
We have started to apply LCA from the R&D stage and to operate a system of developing product designs with consideration for CO2 emissions. We have made trial LCA calculations for approximately 104 product groups (159 representative grade types) as of March 31, 2016.
We continue to make LCA calculations for newly developed product groups and grades.

(3) Development of Environmentally Friendly Products (Current E2 Initiative)

1. Electrode binders for lithium-ion secondary batteries as part of our efforts to create a low-carbon society

The JSR Group offers electrode binders (adhesive) for lithium-ion secondary batteries. These binders have experienced an increase in demand due to efforts for the effective use of energy and the creation of a low-carbon society.
Lithium-ion secondary batteries are used in hybrid and electric vehicles. As with normal dry-cell batteries, these batteries have positive and negative electrodes.
These electrodes are made by bonding carbon materials or metal oxide particles, which function as the activating material, to copper or aluminum foil (collector). Binders provided by the JSR Group are used in this binding process.
JSR Group binders are made by dispersing resin in water, which has a low environmental impact. This point bonding method also significantly reduces the bonding area of the resin that interferes with the electrical continuity of the active substance. This results in the creation of electrodes with low electrical resistance.

Electrode binders
Water dispersion enables low electrical resistance via point bonding.

These electrodes demonstrate the superior performance of JSR Group polymer design technologies, water dispersion technologies, and battery performance evaluation technologies.
Not limited to electric vehicles, our materials are used in a wide variety of products including computers, cellphones, electric vacuum cleaners, and so on.

2. Lithium-ion capacitors that help achieve efficient energy use

Lithium-ion capacitors, which the JSR Group positions as one of its strategic businesses in the JSR2016 mid-term business plan, are an electricity storage device capable of instant charging and discharging together with a long lifespan and little propensity for self-discharge. They are currently at the center of global attention as a key technology for the more efficient use of energy, and their market is expected to expand significantly.
JM Energy Corporation, the industry's leading company, commenced the world's first high volume production of lithium-ion capacitors at the end of 2008. The company's current aim is to develop and offer lithium-ion capacitors with higher performance by utilizing the JSR Group's material and precision processing technologies to expand their applications to various fields.

3. S-SBR technologies have great potential to help mitigate climate change

Fuel-efficient tires are environmentally-friendly products and yet maintain their ability to stop safely and securely. The JSR Group's solution polymerization SBR (S-SBR) has received positive feedback from customers. The JSR Group designed S-SBR using technology that more readily facilitates rubber molecules and tire reinforcing material molecules to bond tightly, which reduces internal friction and rolling resistance*4. In addition, this is achieved without changing the characteristics of rubber that enable tires to stop. S-SBR allows large reductions in environmental impact through the entire lifecycle of the tire, from the material selection and its usage to disposal.
Automobiles will still require tires even after automotive engines are replaced with electric motors. Thus, demand for S-SBR is high both in countries and regions where environmental standards are high, such as Japan and Europe, and in emerging nations where reducing environmental impact is an urgent issue. These tires are currently manufactured at the Yokkaichi Plant in Japan and at JSR BST Elastomer Co., Ltd. in Thailand. We are also considering production operations in Hungary. These global deployments are being undertaken in anticipation of market expansion in 2020. They are carried out based on our supply chain management concepts, which are designed to ensure that production takes place in locations close to markets, ensuring stable material procurement so that the impact due to logistics can be reduced and a stable supply of product can be ensured. By meeting the global demand for fuel-efficient tires using the E2 InitiativeTM concept, we will contribute to solving global environment issues.

SIFCLEARTM is used in paints to make them resistant to contamination, helping maintain cleanness in appearance over the long-term. The high durability of the paint film reduces the need for frequent re-painting, contributing to resource conservation. In particular, when used in heat reflection paints, heat reflection effect is maintained over the long-term, achieving significant energy savings. It is also attracting attention as an environmentally-friendly material because of its ability to prevent Volatile Organic Compounds (VOCs) and the generation of odor.

6. The BIOLLOYTM brand of plant-derived materials

BIOLLOYTM is a bioplastic produced by combining a thermoplastic resin with plant-derived polylactic acid. Compared to existing general bioplastics, BIOLLOYTM has five times greater shock resistance. The product is expected to be used in containers for cosmetics, shampoos, and other products that require thin, light, and eco-friendly materials, as well as in various other applications including automotive interiors, office automation equipment, and household appliances.

7. Mask resist material*5 for injection molded solder processes that significantly simplifies processing and reduces environmental impact

As the miniaturization of transistors and wiring in IC chips continues to advance, demand for high-performance equipment used to build IC chips during semiconductor mounting processes continues to increase. JSR, IBM Japan, and Senju Metal Industry Co., Ltd. have worked together to develop a revolutionary injection molded solder (IMS) process that enables advanced high-density semiconductor mounting processes.
IMS is a technology in which a specialized soldering device directly injects solder into the opening of mask resist material formed on substrates. The mask resist material developed by JSR can resist temperatures up to approximately 250°C, which is the temperature at which solder is used. This enables extremely fine solder bump*6 patterns of 30 microns to be formed anywhere on substrates.
This eliminates the significant amount of plating required with conventional electrodeposition methods, the corresponding maintenance, and the large amount of waste disposal. With a 100% utilization ratio of solder, this environmentally friendly process generates zero process inefficiency and reduces waste products. In comparison with conventional methods, this method simplifies processes and has low environmental impact, and so we hope that this method will be utilized more and more.

*6 Bump: A protrusion of solder that acts as an electrode to electrically connect the semiconductor device to the substrate.

8. HUSHLLOYTM reduces squeak noise, grease application, and non-woven fabric lamination

HUSHLLOYTM*7 is an innovative material designed to reduce squeak noise caused by plastic joints in vehicle interiors. Conventionally, squeak noise prevention is achieved by applying grease or attaching felt fabric to the components, but the use of HUSHLLOYTM has made these countermeasures unnecessary, allowing the component manufacturers to shorten their production process. In addition, since the material itself has the effect of minimizing squeak noise, maintenance is not required for a longer period of time.

*7 HUSHLLOYTM is a registered trademark of TechnoPolymer Co., Ltd.
