Sumitomo Heavy Industries Group is strengthening environmental risk management and global warming prevention measures at overseas factories.
Sumitomo Heavy Industries Group has been continuously reinforcing management systems in order to strengthen environmental risk management at factories in other countries. We have assigned full-time environmental managers at every overseas factory. At factories where production is on the rise, as in China, in particular, we are promoting further measures, such as increasing the number of those managers.
Out of all our Group factories in other countries, the largest number in operation by region is in China, where there are eight. We therefore have a special management system for environmental management matters, as well. In fiscal year 2011, we established a department in Shanghai to handle centralized environmental management for the China area, and in fiscal year 2012 we added one new staff member as part of our further strengthening of the system.
In China, we have been ahead of other regions in establishing environmental management meetings like those held at our factories in Japan. We began holding these meetings there in fiscal year 2011, bringing together the environmental managers from each of the factories in China to hear explanations of environmental policy from the head office in Japan, to report on the status of environmental management at their factories, and to work on raising the level of environmental management at each factory.
In fiscal year 2012, the meeting venue began to be shifted from factory to factory in turn, and on-site environmental patrols are being carried out by all the participants together at each meeting venue factory.
On-site environmental management is said to require experience and practical management know-how. The environmental managers at our China factories have relatively few years of experience, so we are using these environmental patrols to improve the management knowhow and knowledge of the participants as well as to disseminate that know-how and knowledge laterally to every factory.
China and the countries of Southeast Asia are strengthening their environmental standards every year.
We are continuously expanding the scope of management activities at every factory in order to respond to the stronger environmental standards in that country.
In fiscal year 2012, the speed reducer factory in Vietnam installed a new wastewater treatment facility in response to stronger environmental standards instituted at the industrial park where it is located.
In addition, the forklift parts factory in the Philippines has taken steps to reduce the risk of environmental pollution by voluntarily installing a water-sealing plate as an emergency shutoff that will prevent factory wastewater from being discharged into the public sewer if a fault occurs. The installation of this water-sealing plate has been treated as an advanced example of activity to prevent pollution of the environment, and it has been publicized as such within the industrial park.
The head office Environmental Management Division conducts periodic audits of our factories in other countries. In order to reduce the environmental risk at overseas factories to the same level as at factories in Japan, these environmental audits check the environmental management activities at each factory, applying the same audit standards as at factories in Japan.
The frequency of audits is determined according to the environmental risk at the factory in question, taking local environmental requirements into consideration. In fiscal year 2012, environmental audits were conducted at eight of our factories in the China, Europe, and Southeast Asia areas.
At the same time that audits are conducted, environmental managers and officers are also given training in activities to prevent environmental accidents and in energy saving.
CO2 emissions are trending upward at Sumitomo Heavy Industries Group's factories in other countries because of the construction of new factories and the expansion of production at existing factories.
Our Group is setting targets for the reduction of CO2 emissions at factories in other countries, and we are promoting activities to prevent global warming.
In fiscal year 2012, we set reduction targets for all our factories in other countries and promoted activities to reduce CO2 emissions. As a result, we achieved the target value for total emissions of 82,300 tons with the actual figure of 77,315 tons. We will continue promoting reduction activities that are geared to achieving future reduction targets.
At the speed reducer factory in Germany, wall surfaces were almost all converted to glass windows to introduce large amounts of natural light in some workplaces.
Electric power for lighting in these workplaces was further reduced by installing new devices that automatically dim and brighten the interior illumination according to the amount of sunlight.
At the forklift parts factory in Vietnam, the machine workshop areas used to have mercury lamps on the ceilings for lighting. Now fluorescent light-type LED lights have been installed close to the machines to illuminate each machinist's work area.
In addition to their lower power consumption, LED lights turn on instantly. This means the lights can be turned on only when needed, so that power consumption can be reduced rationally. The LED lighting at this factory was also installed in a way devised by the production engineering manager to match with the specific work being done.
Sumitomo Heavy Industries Group's factories in other countries face differing environmental requirements according to the factory location. In order to meet these different demands, we promote environment management activities that are characteristic of those various factories.
The water used at the speed reducer factory in Brazil is ground water, and a well has been dug on the grounds where the water can be pumped up. In order to reduce the amount of water pumped from the well, domestic wastewater and other such water is treated in a wastewater treatment facility installed at the factory, and the treated water is used for such purposes as watering grass and trees on the grounds.
At the construction machinery factory in the United States, a company-wide program is being promoted to reduce the amount of waste generated by the factory.
The waste material that used to be treated as landfill is now being sorted carefully by category. The sorted waste is collected under a program to increase the amount of waste that can be recycled and reduce the weight of landfill material.
New waste collection boxes for recycling material have been placed in the factory. Once a week, employees also check through the waste yard for landfill material to retrieve any recyclable waste that is mixed in.
A unique logo mark has also been created as a symbol for waste reduction activity. Not only is this logo used at exhibitions of waste reduction activity in the factory, but it is also displayed on tape and other such materials used in packing construction machinery parts that are shipped from the factory. In addition to improving awareness of waste reduction within the company, this logo also publicizes the commitment to waste reduction to people outside the company.
People at the speed reducer factory in Brazil drink a great deal of coffee in the factory. At first, disposable cups were used, and most of the cups were disposed of as waste material. However, local employees who wanted to help reduce waste came up with an idea themselves: They made heat-retaining cups carrying the company logo for individual use, and distributed one cup to every employee. This made it possible to eliminate the use of disposable cups.
At the speed reducer factory in Vietnam, the raw garbage generated at the dining hall in the factory is not treated as landfill waste. Instead, a program is being conducted in cooperation with local livestock farmers to use the garbage as animal feed and other such purposes.
