Under the objective of decreasing the impact on the environment induced by hazardous materials in the administration and operation of properties, Mitsui Fudosan Group has been striving to reduce the amount of medical agents used and converting to medical agents with less impact on the environment. Furthermore, we properly maintain, manage and process medical agents and waste with the intent to prevent dispersion, leakages, etc. of hazardous materials.

Glass canopy coated with photocatalysts
Mitsui Fudosan has employed round-shaped photocatalytic water purifiers, which were developed through a collaboration among four companies, for the scenic water of office buildings, etc. Photocatalysts have the function of decomposing organic compounds and bacteria by exposure to light (ultraviolet light) and make use of medical agents unnecessary for cleansing water. Further, we installed one for the scenic water of Aoyama OM-SQUARE (Minato-ku, Tokyo), which was constructed in July 2008.
In addition, photocatalysts have the quality of becoming superhydrophilic by exposure to light (ultraviolet light) and are thus are less prone to become unclean. Therefore, at Tokyo Midtown, photocatalysts have been painted on the glass canopy of Canopy Square and the glass surface of Park Bridge to reduce the amount of medical agents used for cleaning.

First Facilities Co., Ltd. is replacing detergents, waxes and removers used for cleaning and maintenance operations with products that have less impact on the environment, except those designated by customers.
In fiscal 2008, we completed replacements for approximately 90% of the products in the list of first-stage replacement, including detergents for floor surfaces, bathrooms, restrooms and hot water supply equipment. We are currently in the process of conducting replacement for products in the list of second-stage replacement, including detergent for carpets, floor wax and remover, as needed.

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. by ensuring that there are no accidents, such as leakages. In addition, we carry out proper disposal of equipment in accordance with the Law Concerning the Recovery and Destruction of Fluorocarbons upon removal and disposal of such equipment.
At MITSUI OUTLET PARK Tama Minami Osawa (Hachioji-shi, Tokyo), we renewed 110 gas heat pump air conditioners in fiscal 2008 for stage 1 buildings. We carried out proper disposal by entrusting the disposal to a disposal company.

Based on laws and regulations, Mitsui Fudosan Group has filed PCB waste collected when facilities were renovated at its office buildings, retail properties and hotels, and is properly storing, managing and disposing them.

Mitsui Fudosan Group is conducting the removal and containment of asbestos-sprayed materials in office buildings that the Group owns, administrates and operates for which the existence of the concerned materials were confirmed, as necessary. Furthermore, in the buildings that are used on a continuous basis, the materials are properly managed by creating an inventory management book and by regularly implementing visual inspections and air environment measurements.
Further, since other substances were 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 on asbestos-sprayed materials is being conducted as necessary.
