The year 2007 is a very important year as the first commitment period of the Kyoto Protocol starting 2008 is approaching. In light of expanding crude steel production in response to increasing customer needs for highly functional steel products and more energy consumption due to stricter environmental measures, goals of the Voluntary Action Program of the Japan Iron and Steel Federation (JISF) will not be easily attained. Nevertheless, we are determined to make all-out efforts to achieve those goals mainly by reducing CO2 emissions through our technological measures, and partly by using the Kyoto Mechanisms as a complementary measure.
Energy Saving Activities
Iron and steel manufacturing uses coke as a reducing agent during the process of reducing iron ore. The reducing process leads to CO2 emissions. Since the 1970s, JFE Steel has been recovering gases generated from each stage of various processes in coke ovens and BF, etc., in order to use them as fuel gas or gas for power generation and meet fuel demand at respective steelworks. JFE has also been striving to effectively reuse flue gas and waste heat. As a result of these efforts, we have achieved a 35% reduction in unit energy consumption
from the year ended March 1974 level, realizing the world’s top-class efficiency of energy consumption.
JFE Steel will implement further energy savings by promoting operational upgrades such as the addition of CDQ, cutting reducing agents, and using cold iron sources. We will also contribute to the international prevention of global warming and environmental conservation through the Meeting for Environmental Protection and Energy-saving by the CISA and JISF and the Asia-Pacific Partnership based on the cultivated technologies.
Efforts of Iron Industry
(The JISF’s Voluntary Action Program)
The JISF achieved a 6.5% reduction in energy consumption in the year ended March 2006 (6.9% reduction in CO2 emissions) compared to the year ended March 1991 level. As a complementary measure, the JISF has made a purchase contract of the Kyoto Mechanisms (28 million tons).
JFE Steel Corporation Vice President
Takashi Sekita
The JISF’s Voluntary Action Program
The JISF has set a 10% reduction in energy consumption as its goal for the year ending March 2011 compared to the year ended March 1991 level on the assumption that annual crude steel production would amount to the 100 million-ton level. It is also committed to effective use of waste plastics (equivalent to another 1.5% reduction).

CDQ (Coke Dry Quenching) is equipment to quench coke by exposing the dried/heated coke after the coke oven process to inert gas flowing in a cooling chamber. This equipment does not emit dust and realizes sensible heat recovery power generation, which contributes to energy saving. JFE Steel is now carrying forward broader utilization of CDQ into the Kurashiki area.
A regenerative burner alternately uses a pair of burners which are integrated with the thermal storage body, and thereby uses waste heat generated from one burner as preheat for the other burner’s combustion air. This system excels in thermal efficiency and realizes substantial energy saving (CO2 emission
reduction) and NOx emission reduction. CDQ equipment

２ For Compliance with the Voluntary Action Program
JFE Steel is determined to prevent global warming by promoting further energy saving (reduction of CO2 emissions) activities in order to achieve the JISF’s Voluntary Action Program with certainty even though crude steel production is increasing.
We will make concrete efforts such as improving operational efficiency (cutting the reducing agent ratio and utilizing more iron scraps), energy savings by streamlining equipment, and technological innovations through R&D.
Use of the Kyoto Mechanisms
JFE Steel has been promoting the utilization of CO2 emission rights according to the Kyoto Mechanisms as a complementary measure to reduce CO2 emissions in addition to implementing technologies. This is being done so that we can achieve the goals of the Voluntary Action Program with certainty.

Environmental abnormality prevention system
Example of disclosed data
Environmental Abnormality Prevention System (Publication of Environmental Information)
JFE Steel has strived to drastically restructure the en-vironmental management system since December 2004, when the water quality problems were recog-nized at its East Japan Works (Chiba). As part of these efforts, the environmental abnormality prevention sys-tem has been under the construction based on our ac-cumulated expertise. Moreover, real-time information disclosure system on environment was completed in March 2007, and is now open to the general public.

Contribution to Biodiversity
Greening of Steelworks
JFE Steel’s efforts to facilitate green premises at its steelworks have resulted in habitats for precious creatures. For example, little terns are breeding within the premises of JFE Steel’s East Japan Works (Chiba). The breeding ground previously had been put at risk of being flooded because of precipitating water while the premises’ wastewater pathways had been under maintenance. Yet it was eventually protected by absorbing the rain water through pumps. Another example is green space within the premises of the East Japan Works (Keihin), where good habitat conditions allow kingfishers to nest.
Okukusatsu
JFE has been promoting forest conservation such as afforestation and thinning within the area of Kunimura, Agatsuma-gun, Gunma Prefecture. The area consists of a privately owned old open-pit iron mine site and surrounding national forests. As a result of longstanding efforts, forests have been recovered as a habitat for precious plants and animals. Part of this area has been designated as a Natural Holiday Village, where people can enjoy communion with nature.
Reefs for Coral and Seaweed
JFE has been developing restoration technologies for marine environments by utilizing steel slag, which is a byproduct of manufacturing. Porous Marine Block®, which is JFE’s block product made from steel slag and CO2 through a solidification reaction, has been adopted for coral reef restoration works in Sekisaishoko on a trial basis. So far, good results have been observed. Marine Block® has also been used in rejuvenation experiments for seaweed reefs close to Japan because of its excellent performance as an implantation base for seaweed.
Participation in “How Far Do Dragonflies Travel?” Forum
JFE Engineering’s Tsurumi Engineering and Manufacturing Center has been a participant in studies on dragonfly populations since the first survey in 2003. We have provided a survey site within the company premises as well as helped to capture dragonflies. In 2006, it was decided to fill the premises’ experimental tanks temporarily with saline water. Since these tanks were the habitat of dragonfly larvae, researchers carried out a “dragonfly rescue operation” over the weekend by capturing and transferring 100 dragonfly larvae to other tanks. In this way, we have conserved the regional biodiversity.
We were surprised to find various living creatures including over nine kinds of dragonflies, water stick insects, and water boatmen inhabiting our premises. These findings have somehow reminded us of a sense of wonder. Through our forum activity, we not only rediscovered the importance of green space but also could interact with people from various fields. Such experiences have helped us boost our own motivation.

Reducing Environmental Loads
in Business Activities at JFE Steel
Air Quality Preservation
■Reducing Sulfur Oxide (SOx) and Nitrogen Oxide (NOx) Emissions
JFE Steel has implemented active measures to reduce emissions of SOx and NOx. In these actions as well as R&D, particular emphasis has been placed on sintering furnaces, of which emissions of SOx and NOx are especially large in the steel production process. Flue gas desulfurization equipment has been installed at all the company’s sintering furnaces. Flue gas denitrification equipment has also been installed at all sintering furnaces of East Japan Works (Chiba and Keihin).
■Reducing Dust
Since dust is generated from various sources in the steel production process, JFE Steel has been promoting appropriate reduction measures by identifying individual sources and designing specific measures for each source. As for dust generated during combustion, the optimum dust removal equipment has been installed to fit with the dust’s properties. Similarly, to reduce other dust in terms of its generation as well as release, JFE Steel has been developing technologies and upgrading processes.

Water Quality Preservation
JFE Steel has been earnestly promoting circulation/recycling of industrial water consumed in the steel production process, with its industrial water circulation rate* maintained at as a high level as about 93.8%. For release into public waters, wastewater is given appropriate purification treatment so that its pollution loads can be reduced.
* Industrial water circulation rate
Industrial water circulation rate = (Total consumption – Received industrial water) / Total consumption
Effective Utilization of Byproducts
JFE Steel has been recycling byproducts (i.e., iron and steel slag*1, dust, and sludge*2) in the steel production process in the works as raw materials for steel manufacturing and has been promoting effective utilization of byproducts as resources. Moreover, JFE Steel has been actively expanding applications and markets for steel slag products such as Road Cool®. Among such efforts, application developments of environmental restoration materials such as Marine Block® and Marine Base® have been conducted through industry-government-academia collaboration.
*1 Iron and steel slag:
Material consisting of non-iron rock components in iron ore and lime, etc. It separates from and floats on the molten metal. Slag is mainly used as material for cement.
*2 Sludge:
Material remaining after dewatering of the mud-like substance separated and removed by circulating water/wastewater treatment equipment.

Byproduct recycling rate Ⅰ
JFE Steel effectively recycles a wide range of
waste in various processes at steelworks, and thereby supports sustainable societies.
To give a specific example, JFE Steel developed a unique process to effectively utilize carbon and hydrogen components contained in plastics as reducing agents by injection waste plastics instead of cokes into a blast furnace (BF). Actually, the company has become the world’s first practical user of this integrated process, which not only effectively uses plastics but also contributes to reduction of CO2 emissions by reducing consumption of coke in the steel production process.
Moreover, JFE Steel has been successively developing and putting into practical use various recycling technologies, including technology to dechlorinate vinyl chloride into BF feed and other technology to pulverize waste plastics into
BF feed. Recovered hydrochloric acid (separated and refined) from the process of dechlorinating vinyl chloride is recycled in the acid pickling process. Aluminum recovered from waste fluorescents is also recycled as a refining agent in the steel production process. To sum up, steelworks have become important bases for recycling resources.

Reducing Environmental Loads in
Business Activities at JFE Engineering
Preventing Global Warming
The Japan Society of Industrial Machinery Manufacturers formulated a “Voluntary Action Plan for the Environment by the Industrial Machinery Industry” in 1997. The Plan aims for a 12.2% reduction in CO2 emissions from the year ended March 1998 levels by the year ending March 2011.
Under such circumstances, JFE Engineering Corporation has implemented Environmental Management Systems suited to functions and business attributes at each of its works and endeavors to prevent global warming.
The office division has been promoting various energy saving activities, including adoption of the high-efficient Clathrate Hydrate Slurry (CHS) Latent Heat Air-conditioning System and power conservation such as turning off lights during the lunch break and turning off personal computers when not in use. Meanwhile, the production division has implemented power-saving on lighting at factories during sunny daytime, more efficient use of compressed air, and energy-saving check patrols.
Combined CO2 emissions in the year ended March 2007 from the production division and the
office division amounted to 15.3 thousand tons or an 8.9% reduction from 16.8 thousand tons in the year ended March 1991 and an 18.6% reduction from the level of the year ended March 1998.
JFE Engineering has also been striving to determine CO2 emissions in site construction works since August 2004. In addition, CO2 reduction activities such as a “stop idling” campaign have been implemented at construction sites since the year ended March 2007 on a trial basis.

Reducing Generation/Discharge of Waste JFE Engineering strives to reduce generation and discharge of waste.
To give concrete examples, the office division has carried out educational activities through on-site broadcasting and posters, etc., as well as more segmented sorting for the purpose of reducing the landfill disposal rate of office waste. At both Tsurumi Engineering and Manufacturing Center (hereinafter “Tsurumi Center”) and Shimizu Works, the office division achieved the reduction targets for landfill disposal rates. Meanwhile, the office division at Tsu Works has been working on waste reduction together with the production division.
The production division has endeavored to reduce unit waste discharge per hour. Both the centers and works have worked on thorough sorting, complete sorting and effective use of recyclable waste, and industrial waste patrol to check sorting conditions. Shimizu Works achieved its reduction target, while Tsurumi Center and Tsu Works could not reach their targets due to changes in operations and other factors.
In site construction works, JFE Engineering has been promoting activities to reduce the landfill disposal rate, including sorted collection of rubble,
waste pipes, waste metals, waste plastics, and waste wood, etc., efforts toward smaller bulk, and a recycling campaign. As a result of these activities, the landfill disposal rate at site construction works came to 32.4%, achieving the target of 35% or less ahead of the deadline of the year ending March 2008. The planning and designing division has been also making environment-friendly plans and designs by adopting recycling materials or selecting energy-saving equipment, etc.
Control and Reduction of Chemical Substances In compliance with the Pollutant Release and Transfer Register (PRTR) Law, JFE Engineering controls release and transfer volumes of the designated chemical substances and reports those figures to the national government through local governing bodies. The company has been promoting activities to reduce the controlled substances including paints, solvent, and gasoline. Moreover, its reduction efforts go beyond such PRTR substances and include gases, CO2 and propane, etc., to make its business activities environment-friendly.
Educational poster to reduce office waste
At the office division in Tsurumi Center, JFE Engineering has increased the number of sorted office waste items from 4 items to 14 items since the year ended March 2006 in order to further promote recycling efforts. In the year ended March 2007, generation of office waste in Tsurumi Center increased by 27% year to year mainly due to transfer of some headquarters functions to Tsurumi area, while the recycling efforts resulted in a 37% increase in recycled volume.

Preventing Global Warming
In the year ended March 2007, energy-origin unit CO2 emissions per capacity utilization increased, while the energy saving rate* reached 0.78% as a result of introduction of inverter control for compressors and other measures.
As part of efforts to reduce emissions of PFC gases, Kawasaki Microelectronics, Inc. has implemented an experiment to replace C2F6 gas (accounting for approximately 70% of total emissions of PFC gases) by
substitutes since the year ended March 2006. The basic assessment and consideration for practical use was completed in the year ended March 2007. Accordingly, the company is determined to work on such shifting in the year ending March 2008.
Reducing Generation/Discharge of Waste Kawasaki Microelectronics succeeded in recycling plastic packaging materials as valuable substances in the year ended March 2007, after having achieved such recycling of non-ferrous metals in the year ended March 2005 and semiconductor containers in the year ended March 2006.
Control and Reduction of Chemical Substances Kawasaki Microelectronics succeeded in replacing acetic acid 2-etoxyethyl with substitutes in the year ended March 2007, following the replacement of N, N-dimethylformamide in the year ended March 2006. In addition, the company reduced emissions of catechol by improving its use conditions. As a result, only one substance is now subject to PRTR reporting requirements.
