Prevention of Air Pollution
Measures to Address Exhaust Gas at Facilities Producing Soot and Smoke
Boilers, cogeneration systems, and other soot and smoke producing facilities larger than a certain size and installed at office buildings, retail facilities, hotels, large-scale logistics facilities, and other properties managed and operated by the Mitsui Fudosan Group, are subject to regulation under laws, regulations, and ordinances relating to air pollution.
At these regulated soot and smoke producing facilities, we have installed exhaust gas treatment equipment, and we are working to prevent air pollution by curbing emission of air pollutants such as nitrogen oxides and sulfur oxides.
Measures to Address Exhaust Gas at Mitsui Repark Parking Lots
At the Mitsui Repark pay-by-the-hour parking lots of Mitsui Fudosan Realty, we are working to reduce the in-lot effects of automobile exhaust gas by installing exhaust gas panels on the perimeter.
At Mitsui Repark's Enkobashi-cho No. 3 Parking Lot in Hiroshima, exhaust gas panels with photocatalytic filters were installed. When light such as sunlight strikes these panels, a powerful oxidizing effect is produced, and this enables removal of organic compounds and other hazardous materials which come into contact with the panel.

Prevention of Water Pollution
Wastewater Treatment at Office Buildings, Retail Facilities, and Hotels/Resorts
Restaurants above a certain size in office buildings and retail facilities, as well as hotels and resort facilities managed and operated by the Mitsui Fudosan Group are subject to regulation under laws, regulations, and ordinances relating to water pollution.
At these regulated facilities, we install wastewater treatment equipment, and discharge wastewater into sewage systems, rivers, the ocean, or other public waters only after treatment that ensures it meets regulatory standards.
Lowering Environmental Impact of Cleaning Solutions
Mitsui Fudosan Facilities has been using to eco-chemicals with low environmental impact based on its own standards, with the exception of chemicals designated by its customers, for cleaning solutions (toilet cleaner, floor and general-purpose cleaner, wax, and removers). As of the end of March 2019, the usage rate of eco-chemicals has risen to more than 90%.
Mitsui Fudosan Residential Service in principle uses cleaning solutions with low environmental impact based on its own standards for cleaning condominiums, with the exception of some managed properties.
Mitsui Fudosan Residential Service's Standards for Cleaning Solutions with Low Environmental Impact
- Cleaning solutions that satisfy the following conditions:
- ◎More than 60% biodegradable (after 28 days)
- ◎Chemically neutral
- ◎Low biochemical oxygen demand (BOD) and chemical oxygen demand (COD)
Responding Appropriately to Soil Contamination
The Mitsui Fudosan Group complies with relevant laws and regulations for surveying soil history. We also implement soil contamination surveys and take measures to remedy contaminated soil as needed.
Reduction of Hazardous Substances
Appropriate Disposal of Chlorofluorocarbons
When equipment containing chlorofluorocarbons is disposed of at our office buildings, retail facilities and hotels, it is handled in an appropriate manner in accordance with relevant laws and regulations.
Responding Appropriately to Asbestos
In demolition and repair of buildings, retail facilities, condominiums and other structures, we observe laws and regulations relating to asbestos, and take proper measures such as notifying government agencies, and preventing the dispersion of asbestos.
Sick Building Countermeasures
For our office buildings and retail facilities, we have added guidelines for combating sick building symptoms to our eco-specifications (for design, etc.). We make concerted efforts to prevent formaldehyde and other volatile organic compounds (VOCs) from entering our buildings, because they are a cause of sick building syndrome. Mitsui Garden Hotels uses low-formaldehyde building materials* including building components, adhesives, and paints.
The housing business promotes the use of low-formaldehyde building materials to limit substances that cause sick building syndrome, such as formaldehyde.
*Low-formaldehyde building materials : Building materials rated by Japanese Industrial Standards (JIS) and Japanese Agricultural Standards (JAS) as having the minimal or second-lowest level of formaldehyde emissions.
Measures to Address Indoor PM2.5 Pollutants
Mitsui Home offers Smart Breeze, a healthy air-conditioning system for its custom-built detached residences. Smart Breeze is a 24-hour ventilation system, equipped with a high-performance filter that captures particulate matter of around 2.5 μm in size. This prevents infiltration not only of pollen and dust, but also of PM2.5, an air pollutant thought to have effects on health.
Overview of High-Performance Filter
The Mitsui Fudosan Group is working, together with business partners, tenant companies and stores, and customers, to conserve resources and reduce waste through the 3Rs (reduce, reuse, and recycle), while striving to prolong the useful life of its buildings. We also appropriately dispose of wastes.
To reduce the generation of waste, we make every effort to restrict the use of disposable products, and have introduced a metering system.
Metering System at Retail Facilities
In an attempt to reduce waste from stores, our retail facilities feature a metering system that charges for the volume of waste generated.

The Mitsui Fudosan Group aims to reuse materials instead of throwing them away to conserve resources and reduce waste.
&EARTH Clothing Support Project
Every year since 2008, we have held the &EARTH Clothing Support Project — Bring a Smile to the World with Your Clothes — at retail facilities operated by the Mitsui Fudosan Group.
In this project, unneeded clothing is collected, and then donated to refugees and disaster victims in countries all over the world through the NPO Japan Relief Clothing Center. By promoting reuse of clothing, we contribute to the reduction of waste, and by working collaboratively with NPOs active on the international stage, we also help support people who need assistance due to poverty, natural disasters brought on by climate change, and conflicts.
In an effort to conserve resources and reduce waste, the Mitsui Fudosan Group promotes the recycling of food waste along with paper, fluorescent light bulbs, and batteries using our proprietary recycling system. We also make every effort to use recycled items.
Recycling Food Waste
At our office buildings and retail properties, working together with restaurants, food waste from restaurants is recycled into fertilizer and feedstock for livestock, or converted into biomass energy (electricity and gas).
Recycled Food Waste (fiscal 2018)
At the resort hotel HAIMURUBUSHI (Taketomi Town, Yaeyama District, Okinawa Prefecture), we make compost out of coffee grounds from our restaurants, and use this compost to cultivate herbs and vegetables in the hotel gardens. In turn, the herbs and vegetables are served in our restaurants. Other food waste is processed on the premises with a food waste processor that uses microbes.
At TOBA HOTEL INTERNATIONAL (Toba City, Mie), used cooking oil is collected and handed over to an industrial waste disposal company for recycling as fuel. Similarly, NEMU RESORT (Shima City, Mie) has been recycling used cooking oil since fiscal 2005.
Recycling of Environmentally Friendly Tile Carpeting
Used tile carpeting from office buildings managed by the Mitsui Fudosan Group is collected and recycled into environmentally friendly tile carpeting, which is then reused in office buildings in the Tokyo metropolitan area. This recycling system uses environmentally friendly tile carpeting to conserve resources and reduce incineration waste, which in turn helps reduce CO2 emissions.

Wastepaper Recycling Loop System
In collaboration with traders of used paper, paper manufacturers, and paper distributors, the Mitsui Fudosan Group has created a unique recycling loop system for wastepaper, which is collected from office buildings managed by the group in Tokyo, and from LaLaport TOKYO-BAY (Funabashi City, Chiba). The wastepaper is recycled into original recycled office paper and is reused as toilet paper.

Used Fluorescent Bulb and Battery Recycling System
Mitsui Fudosan has established a recycling system for used fluorescent bulbs and batteries in cooperation with four subcontractors including a recycling company and a transport company. Used fluorescent bulbs and batteries at office buildings managed by the Mitsui Fudosan Group are recycled through this system. Mercury extracted from the collected used fluorescent bulbs and batteries is reused as a raw material for new fluorescent bulbs. Separated aluminum and glass are also reprocessed into recycled aluminum and glass to recycle everything that can be recycled.

Recycled Office Paper Usage Ratio in Mitsui Fudosan’s Offices
In fiscal 2018, about 93% of the business paper used* was recycled paper in Mitsui Fudosan’s offices.
*Ratio of recycled business paper used: The ratio of recycled paper used for all business paper (weight basis).
Recycling Efforts at Tokyo Midtown
At Tokyo Midtown (Minato-ku, Tokyo), we classify wastes into 21 types, and we are working together with shops and tenants to recycle and appropriately dispose of waste. We have a total of 10 separated garbage storage spaces, by building and application, and appropriately store and manage waste until it is carried away from the site. In addition, we are working to ensure proper separation and recycling by installing garbage stations with easy-to-understand separation instructions in the offices of Tokyo Midtown Management.
Extending the Useful Life of Buildings
The Mitsui Fudosan Group aims to extend the useful life of buildings, including office buildings, condominium buildings (built-for-sale, rental units) as well as detached houses (for-sale and customized), by enhancing their ability to withstand earthquakes, overall durability, and fire resistance, while also designing them so that maintenance and upgrading of plumbing and other equipment can be carried out easily. In addition, we engage in appropriate maintenance and renovations after buildings go into service.
For example, Mitsui Home offers the Keep Well long-term building support system to maintain quality and performance over the long-term, through a combination of inspection and upkeep every 10 years after building delivery.
Our efforts to extend the useful lifespan of our buildings lead directly to resource conservation and waste reduction.
Efforts to Appropriately Dispose of Waste
The Mitsui Fudosan Group promotes the 3Rs, and we appropriately dispose of wastes that cannot be reused or recycled based on laws, regulations, and ordinances relating to appropriate disposal of wastes.
On-Site Inspection of Waste Management Subcontractors and Disposal Facilities
In the Office Building Division, we make every effort to ensure that waste is disposed of appropriately, and to this end we conduct on-site inspections of our industrial waste management subcontractors, which are required to cooperate based on the Waste Disposal and Public Cleansing Act.
In the Retail Facility Division, from fiscal 2011 to fiscal 2012, we confirmed that waste was properly disposed of at our retail facilities in Japan, completing any adjustments to our agreements with waste management subcontractors. We audit and inspect numerous retail facilities annually to ensure compliance with adjusted waste disposal agreements.
Appropriate Storage, Management, and Disposal of PCB Waste
The Mitsui Fudosan Group appropriately stores, manages, and disposes of PCB waste at its office buildings, retail facilities, and hotels based on the Law Concerning Special Measures Against PCB Waste.
