Activities to Counter Global Warming

Participation in Team Minus 6% National Movement
  The Kyoto Protocol for the prevention of global warming took effect in February 2005 and the Japanese government announced its program to attain the Kyoto Protocol goals April 2005. On this occasion, the Anritsu Group in Japan registered its participation in the Team Minus 6% national movement advocated by the Ministry of the Environment promote our activities to help counter global warming.
  We called on our Group Companies in Japan through newsletters to (1) adopt "Cool Biz" and "Warm Biz" energy-saving dress codes for summer and autumn/winter, respectively, and adjust air conditioner settings accordingly, (2) save electricity and water, (3) replace instruments with energy-saving models, (4) refrain from commuting by car, (5) stop engine idling and introduce fuel-efficient vehicles, and (6) provide information on energy-saving products services to customers. We also used posters, banners the intranet to ask Group Companies for their cooperation in order to promote the activities.

Results of Team Minus 6% (Atsugi Site + Tanasawa Site + Tohoku Site)

Energy-Saving Activities at Tanasawa Site
  The Tanasawa Site, our device manufacturing plant, reviewed operating conditions of clean rooms and other facilities and (1) distributed air from the high-level clean room to the medium-level clean room to cut power for air conditioning in the latter, (2) reduced load (electric power) on water cooling systems by changing the temperature conditions for cool water distribution to clean rooms to match the temperature/humidity loads of the rooms, (3) made arrangements to allow selective operation of freezers consuming high power or cooling systems consuming low power, depending on temperature/humidity loads of the clean rooms, to reduce power consumed for cooling, and (4) reduced power consumption of pumps by stopping the water cooling systems when not needed. As a result of these energy-saving measures, the Tanasawa Site was able to cut power consumption by some 118 MWh (i.e., CO₂ emissions by 44 tons) a year.

CO₂ Cut by Making Efficient Procurement of Transport
  Tohoku Anritsu Co., Ltd. and Anritsu Industrial Solutions Co., Ltd. had been using their own transportation companies to procure transport between them and their suppliers entrusted with processing and manufacturing, but after making a survey of suppliers' transport systems, decided to operate joint transport services. Tohoku Anritsu operates joint services on two routes for different delivery frequencies, while Anritsu Industrial Solutions operates them on three routes for different destination areas to reduce CO₂ emissions by improving transport procurement efficiency.

Waste Reduction

English Display on Waste Bins
  In accordance with the globalization of the Anritsu Group, employees from outside Japan have increased in number at our Atsugi Site. Accordingly, we improved waste bin displays to identify the bins clearly by waste type and number, and by adding an indication in English. In addition, we are providing education to encourage these employees to understand the importance of recycling.

Turning Component Packing Plastics into Valuable Resources
  Tohoku Anritsu generates a large amount of plastics used for packaging of components at the time of product assembly. The company used to dispose of these plastics as industrial waste. But the category of such material is now clearly indicated on the packages, which enables the waste to be separated according to type. Tohoku Anritsu, after consultation with waste disposal companies, has improved its waste separation to extend classification of waste into nine categories according to material and color, and made it possible to output waste plastics as valuable resources. As a result, the company transformed 170 kg of waste plastics a month, or about 17% of the monthly average emission of 986 kg, from industrial waste into valuable resources.

Packaging and Transportation

No packaging, returnable boxes
  Anritsu Kousan Co., Ltd., our Group Company in charge of transportation, ships out products without packaging. In order to decrease the use of cardboard boxes for packaging, Anritsu Customer Services Co., Ltd., another Anritsu Group Company, uses returnable plastic boxes. The returnable boxes were developed jointly with a transport company for transportation of measuring instruments before and after repair and calibration of the instruments upon customer request.

Management of Chemical Substances

Use of Substances Subject to PRTR Law
  According to the Pollutant Release and Transfer Register (PRTR) Law, Anritsu used 41 substances out of 354 substances designated as category 1 chemical substances. The Atsugi, Tanasawa and Tohoku sites did not use any substance subject to reporting to administrative agencies in fiscal 2005. However, the Atsugi site greatly increased its use of epoxy resin [bisphenol A epoxy resin (liquid)] for metal detectors, after this usage shifted from outsourced production to internal production by Anritsu Industrial Solutions Co., Ltd., an Anritsu Group company.
  We will continue to improve processes to reduce use of chemical substances, including those covered by the PRTR Law.

Chemical Substance Reduction at Tanasawa Site
  Anritsu Corporation and Anritsu Device Co., Ltd. reviewed wastewater treatment processes at the Tanasawa Site, as it uses the largest amount of chemical substances among our sites for wastewater treatment. As wastewater contains fluorine, we used to neutralize all water after fluorine treatment. An analysis of fluorine ion concentration and pH of untreated wastewater collected in a drainage tank showed, however, that there was little water that required fluorine treatment. Therefore, we decided to stop conventional fluorine treatment of wastewater around the clock, and carry out this treatment only when considered necessary after collection and analysis of a certain amount of wastewater in the tank.
  As a result, minor changes such as pipe replacements sharply reduced the volume of chemical substances used for wastewater treatment, from 4,664 kg in fiscal 2002 to 69 kg in fiscal 2005. At the same time, emission of sludge during wastewater treatment also decreased.

PCB Management
  The Atsugi Site deals with capacitors for electrical devices, fluorescent lamp stabilizers and pressure-sensitive copying paper that use polychlorinated biphenyl (PCB). But they are strictly managed in line with storage standards for industrial waste requiring special management. Under the special measures law for the promotion of proper disposal of PCB waste, Anritsu Corporation has been submitting a storage status report to the prefecture every year. When we analyzed oil contained in large transformers at the time an extra-high-voltage substation was replaced in 2005, we found that two of the transformers contained a very small amount of PCB. We plan to dispose of the capacitors in storage at our site in 2007, filing an application for disposal with Japan Environmental Safety Corporation at an early stage.
