Under the objective of decreasing the impact on the environment induced by hazardous materials in the administration and operation of properties, Mitsui Fudosan has been striving to decrease hazardous materials through efforts such as reducing the amount medical agents used and converting to medical agents with less impact on the environment. Furthermore, we properly manage and process hazardous materials with the intent to prevent impact on the environment from hazardous materials leaked, dispersed, etc.

Photocatalysts have the function of eliminating organic compounds and bacteria that come into contact with its surface from the strong oxidative power generated on its surface by exposure to ultraviolet light. Making effective use of this function of photocatalysts, Mitsui Fudosan has employed round-shaped photocatalytic water purifiers, which were developed through a collaboration among four companies, for the scenic water of the ornamental ponds at the Shinjuku Mitsui Building (Shinjuku Ward, Tokyo), Tokyo Midtown (Minato Ward, Tokyo) and Celestine Shiba Mitsui Building (Minato Ward, Tokyo) and the cooling tower of Mitsui Bekkan (Chuo Ward, Tokyo), which has led to reduced use of medical agents. Further, this purifier is also installed for the scenic water in Akasaka Biz Tower (Minato Ward, Tokyo). In addition, photocatalysts have been painted on the exterior walls of buildings and the glass of smoking lounges to verify their effect.

First Facilities Co., Ltd. is switching medical agents used for cleaning to those that have less impact on the environment. The company has been conducting studies with several manufacturers on detergents and waxes that have a lower impact on the environment and verifying the study results. Based on the results, the company formulated voluntary selection criteria and selected the recommended products in fiscal 2007. Except for those detergents designated by customers, replacement of detergents previously used for floor surfaces, bathrooms, restrooms and hot water supply equipment to recommended detergents has been conducted as necessary. In addition, with regard to detergent for carpets, floor wax and remover, performance tests of candidate products are being conducted. Further, in an effort to reduce the overall amount of detergents used, use of electrolyzed water and micro fiber cloths made of ultra-fine fibers several-hundredths of a hair thick is being studied.

In existing office buildings, retail properties and hotels, we are switching air conditioners and refrigerators to those that do not use specified CFCs as they are replaced. We carry out proper management of equipment we own that uses specified CFCs, etc. In addition, proper management is conducted in accordance with the Law Concerning the Recovery and Destruction of Fluorocarbons upon removal and disposal of such equipment.

Based on laws and regulations, Mitsui Fudosan has filed PCB waste collected when facilities were renovated at its office buildings, retail properties and hotels, and is properly storing and managing them. During the period between April 2007 and June 2008, we completed the disposal of PCB waste from 73 units (34 condensers and 39 transformers, etc.) in seven office buildings. Despite completing the haulage of 264 units (condensers) at five office buildings to a disposing facility, disposal of those units is behind schedule.
In addition, PCB waste is still owned at four office buildings, two retail properties and one hotel but it is being properly stored and managed.

Mitsui Fudosan completed an investigation on the usage of asbestos-sprayed materials in office buildings that the Group owns, administrates and operates. In the buildings in which the investigation confirmed the existence of asbestos, removal and containment of the concerned materials and other measures are being conducted as necessary. In the buildings that are used on a continuous basis, the materials are properly managed in accordance with the guidelines issued by the Tokyo Metropolitan Government, which are said to be the strictest in Japan. In addition, a system of emergency measures when emergency conditions arise such as the dispersal of pieces of asbestos was established in fiscal 2007 and began to be implemented in fiscal 2008.
Further, since another substance was added to those subject to asbestos analysis in building architectural materials in February 2008, for a total of six substances to be checked, additional investigation is planned to be conducted within fiscal 2008.
