Greenhouse Gas Emissions

The Nisshinbo Group's greenhouse gas emissions totaled 641,700 tons of CO2, down 4% YoY after adjustments*. Greenhouse gas emissions per unit of sales totaled 1.259 tons of CO2 per million yen, down 3% year-on-year (YoY) after adjustments*. One reason for the decrease was the completion of production of large-scale orders for LNG insulation materials in the chemicals business.

Perfluorocarbons (PFCs) composed 79% of non-energy derived greenhouse gas emissions. The primary emitters of these PFCs were New Japan Radio Co., Ltd. and the microdevice manufacturing processes of Ricoh Electronic Devices Co., Ltd.

* Effective from the previous consolidated fiscal year, we have changed the fiscal year-end from March 31 to December 31. As a result, the previous consolidated fiscal year, which is the transitional period, was an irregular fiscal year. For this reason, the rate of year-on-year change in actual results is not stated. Instead, when comparing the fiscal year under review with the previous fiscal year, for reference purposes, we state the rate of increase/decrease in greenhouse-gas emissions and greenhouse-gas emissions per unit of sales from the same period of the previous fiscal year, adjusted to be the same 12-month period as in the consolidated fiscal year under review, to the consolidated fiscal year under review.

Reduce the emissions of greenhouse gases

Ricoh Electronic Devices Co., Ltd.'s Yashiro Plant expanded its system of greenhouse-gas abatement equipment, to reduce atmospheric emissions of greenhouse gases used in the production of semiconductors.

Greenhouse gases used in the manufacturing of semiconductors have a higher global warming potential than carbon dioxide, making the reduction of atmospheric emissions crucial to addressing climate-change issues. We therefore place priority on installing pollution scrubbing systems on production equipment that emits a large volume of greenhouse gases, to break down greenhouse gases (PFCs and SF6). In addition, we are making progress on the planned upgrading of pollution scrubbers.

In March 2018, we upgraded our pollution scrubbers. By selecting equipment with high processing capacity, we were able to connect four new production systems to the scrubbers, thereby reducing greenhouse gas emissions by 50%. We will continue to work to reduce greenhouse gas emissions in an efficient manner through future upgrades.

Similarly, NJR FUKUOKA CO., LTD. has introduced equipment to remove PFCs, a greenhouse gas, to reduce greenhouse-gas emissions.

Separator components: Core components of fuel cells

Nisshinbo Chemical Inc. has been supplying separators to fuel cell manufacturers around the world since 2000. Separators are components that separate the individual cells* inside a fuel cell. Their role is to separate and isolate hydrogen and air, maintaining flow in uniform contact along the entire ion-exchange membrane. Each separator contains dozens of channels to ensure a uniform flow of gas across the whole fuel cell.

In Japan, we have delivered products for household fuel cells (ENE·FARM) for more than 10 years. In 2010 these products were adopted by Daimler AG in Germany and Ballard in Canada for automotive applications. Nisshinbo Chemical supplied enough separators for 280 Daimler AG fuel-cell vehicles (B-Class), three of which embarked on a trip around the globe. In addition, the separators for 20 buses at the 2010 Vancouver Olympics were delivered to Ballard and installed.

Currently, our separators are attracting attention around the world, and the Nisshinbo Group is looking forward to great results in this field in the near future.

* Cells: The smallest unit of a fuel cell is referred to as a "cell". It has a structure that interposes electrolytes (substances that permit only ions to pass) between the fuel and air poles.

Blowing agent for rigid polyurethane foam

Nisshinbo Chemical Inc. is working to eliminate fluorocarbons from rigid polyurethane foam. This foam is used for insulation of houses and buildings, as well as for cold-chain components such as refrigerator trucks (reefers) and commercial refrigerators and refrigerators, and for the repair of cavities behind tunnels.

HFCs, which are used as a blowing agent, have a global warming potential (GWP)*1 greater than 800. GWP has been added to greenhouse-gas regulations under the Kigali Amendment to the Montreal Protocol*2. Therefore, we are switching to hydrofluoroolefins (HFOs), which is not a fluorocarbon and has a GWP of 1.

In fiscal 2019, 43% of the foaming agents used were switched to HFO, reducing carbon-dioxide emissions by 7,900 tons in comparison with fiscal 2018. Going forward, we will further promote the use of non-fluorocarbons to contribute to the prevention of global warming.

*1 Global Warming Factor: A figure that expresses a substance’s atmospheric warming effect as a multiple of that of carbon dioxide.

*2 Kigali Amendment to the Montreal Protocol: Adopted at the 28th Meeting of the Parties (MOP28) held in Kigali, Rwanda in October 2016 and entered into force in January 2019

Climate change adaptation shirts

Tokyo Shirts Co., Ltd., the only producer/retailer Specialty store retailer of Private label Apparel(SPA) in the Nisshinbo Group, sells men's and ladies' shirts. In response to the enactment of the Climate Change Adaptation Law of 2018, we are actively developing products that comply with the "cool-biz" and "warm-biz" directives.

In particular, super-wrinkle-resistant shirts made from super-wrinkle-resistant supima cotton* are popular throughout the year because they stay wrinkle-free without ironing. This feature also contributes to reducing greenhouse gas emissions by reducing electricity consumption. The use of supima cotton provides customers with soft-textured shirts, saves time-consuming ironing and offers comfort throughout the year.

* Supima cotton is a high-grade cotton with a long staple of more than 35mm, cultivated in Arizona, southwestern America. It is highly moisture-absorbent, soft and smooth, and has a beautiful, silk-like gloss.

Consumption of carbon dioxide (CO2) at plant factories

Nisshinbo Holdings Inc.’s Fujieda Plant and Tokushima Plant cultivate strawberries at a fully controlled plant factory using LED lighting. We are able to conduct year-round cultivation of delicious strawberries, which are normally only available in season, steadily throughout the year without being affected by unseasonable weather, typhoons or other disasters.

Strawberry cultivation promotes plant growth by providing CO2 that is indispensable for photosynthesis at higher levels than natural. CO2 is generated by recovering it from chemical plants and refining it. Because CO2 is kept in the plant factory instead of emitted into the atmosphere, this process contributes to the prevention of global warming. The amount of CO2 used was about 40 tons of CO2 annually at the Fujieda and Tokushima Plants, and the amount of O2 produced by photosynthesis was about 30 tons of O2 annually.

Sales of Climate-friendly Housing

The Real Estate Division of Nisshinbo Holdings Inc. is engaged in a housing lot sales business in collaboration with a major house builder. A total of 357 housing units are under construction on the former site of the Miai Plant (Okazaki City, Aichi Prefecture).

To cope with rapid climatic changes and frequent natural disasters, these homes are standard-equipped with photovoltaic power generation systems (installed capacity of 3.5 KW), ENE·FARM (max output of 700 W) and lithium-ion storage batteries (storage capacity of 5.4 KWh).

By combining a photovoltaic power generation system with an ENE·FARM battery to generate electricity, we aim to reduce the amount of electricity purchased from power companies and increase energy self-sufficiency, while securing an off-grid power source that can be used during large-scale power outages caused by natural disasters and other factors. Some houses were completed and offered for sale in fiscal 2019.
