Pollution Control and Effective Use of Resources

Policy, Concept, and System

The waste and hazardous substances produced 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 resource-saving activities and the reduction of the environmental impact through every opportunity and strive to prevent pollution and effectively use resources through the reduction and appropriate management of the waste and hazardous chemicals that are produced.

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 have also adopted a centralized waste management system that utilizes an electronic manifest in 2018 to properly and accurately control as well as grasp waste emissions.

[2018 Waste Reduction and Management Initiatives]

  • Encouragement for the adoption of reuse and recycling products in property management manuals
  • Improvement of recycling rate through thorough separation and informational sharing
  • Promotion of bottle cap recycling
  • Recycling of spent fluorescent tubes and dry cell batteries: 32
  • Convening of meetings to promote the separation of garbage for tenants: 4

Measures for Asbestos

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

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 Against Volatile Organic Compounds (VOC) in Construction Materials

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.

Proper Processing of Polychlorinated Biphenyl (PCB)

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. (Electronic devices processed in 2018: 96 drum cans; 10 pail cans)

Nitrogen Oxide (NOx) and Sulfur Oxide (SOx) Measures

Tokyo Tatemono regularly measures the concentration of Nitrogen Oxide (NOx) and Sulfur Oxide (SOx) as well as other chemicals emitted from equipment producing smoke and soot, such as the cooling and heating systems as well as boiler equipment used in some office buildings. We also comply with the environmental standards defined in the Air Pollution Control Act in the operation of these systems.
