Waste and Hazardous Substance Management

Policy, Concept, and System

The waste and hazardous substances produce through our business activities have the potential to greatly impact related parties and the surrounding environment.
The Tokyo Tatemono Group has raised resource-saving activities that are kind to the earth as one part of the Group Environmental Policy. We work at water-saving activities and the reduction of the environmental impact through every opportunity and strive to minimize the impact on people and the environment through the reduction and appropriate management of the waste and hazardous chemicals that are produced.

Indicators and Results

●Collection Period
  • April to the following March each year
●Collection Scope
  • Facilities required to provide notification under the Act on the Rational Use of Energy
  • *
    The floor area of buildings for reporting changes each year.
●Collection Targets
  • Total waste emissions and unit load

Trends of Floor Area for Reporting
(Standard Unit Load)(revised June 2018)

Trends of Floor Area for Reporting (Standard Unit Load)
  • *
    The unit load is calculated by adding the occupation rate to the floor area of the building for reporting.
    The floor area of the building for reporting changes each year.

Trends of Waste Emissions

Waste Reduction and Management Initiatives in the Office Buildings Business

In the office buildings owned and managed by Tokyo Tatemono, we are working to limit the production of waste and promote recycling by strengthening sorting and recycling of garbage. We also visually inspect waste treatment facilities so that waste is disposed of appropriately.

[Waste Reduction and Management Initiatives (New/Existing Buildings)]

  • Encouragement for the adoption of reuse and recycling products in property management manuals
  • Improvement of recycling rate through thorough separation and informational sharing
  • Recycling of spent fluorescent tubes and dry cell batteries (2017: 2 new buildings; 32 existing buildings)
  • Visual confirmation of waste treatment facilities (2017: 1 new building; 2 existing buildings)
  • Convening of meetings to promote the separation of garbage for tenants
  • Promotion of bottle cap recycling

Measures for Asbestos

Asbestos causes health problems such as lung cancer when the particles are breathed in. The Ordinance on Prevention of Health Impairment due to Asbestos was enacted in July 2005 and business operators have the duty to take steps such as the removal, containment, and secure storage if there may be a risk of scattering, such as spraying asbestos in buildings where employees work.
Tokyo Tatemono has conducted surveys on the usage status of spraying materials that contain asbestos for all the buildings it owns. In buildings the use of asbestos was found, we took the proper steps such as the removal and containment and shared information with the tenants.

Proper Processing of Fluorocarbons

Fluorocarbons are used in large amounts as coolants and solvents, but fluorocarbons are clearly a chemical and greenhouse gas causing the depletion of the ozone layer.
Today, broad restrictions have been applied to the use of fluorocarbons. Tokyo Tatemono complies with the Act on Rational Use and Proper Management of Fluorocarbons to protect the ozone layer and prevent global warming. We limit the use of controlled fluorocarbons (CFC, HCFC, etc.),
more strictly recover coolants, and thoroughly check for leaks through simplified and regular inspections to limit the release of fluorocarbons into the atmosphere.
Moreover, in renewal of the air-conditioning systems in buildings and in the demolition of buildings, we are properly processing the fluorocarbons of air-conditioning systems that are collected.

Measures to Prevent Sick Building Syndrome

The impact on health from chemical substances produced from construction materials (Sick Building Syndrome) is regarded as a problem, and regulations to address this sick building syndrome have been stipulated in the Revised Building Standard Law enacted in July 2003.
To maintain the health of tenants and other residents in buildings, Tokyo Tatemono restricts the use of products emitting formaldehydes, which is a substance that is the primary cause of sick building syndrome, in buildings separate to the regulations of the Building Standard Law to define standards to counter formaldehydes. We measure the concentration of formaldehydes in new buildings in accordance with these standards to verify the safety of the indoor environments.

PCB Management

Polychlorinated Biphenyl (PCB) is used for a variety of applications, but the new manufacture of PCBs are restricted today because the adverse effects on the human body are clear.
The electronic devices that contain PCBs (transformers, capacitors, and stabilizers) that are no longer used in each building owned by Tokyo Tatemono are collected and managed in a PCB storage room of the designated building to reduce risks such as loss and leakage accidents. In 2017, we processed waste with trace PCB currently stored and some waste with high-concentration PCB through a specialized treatment operator.
