Industrial Waste Disposal and Recycling

Among the industrial wastes generated at sites where Taikisha performs construction work as main contractor, Taikisha encourages 4R* activities whereby wastes are collected in a classified manner for recycling so that landfill at final disposal sites is reduced and the amount of mixed waste is curbed.The disposed industrial waste is sorted into the categories of recycling and final disposal for landfill. The recycled resources are indicated as a recycling rate.

4R* :
Refuse (eliminating waste in resource use)
Reduce (reducing waste)
Reuse (reusing waste)
Recycle (recycling waste)

Industrial Waste Disposal and Recycling

Suitable Waste Management

All of projects whose main contractor is Taikisha are listed up and the waste disposal status is monitored to ensure the waste is treated suitably. Also, local government permit information of all industrial waste disposal agencies with which Taikisha has contracts is collected, listed, and regularly updated on its internal database, and Taikisha develops and manages a scheme whereby contracts are concluded only with the listed agencies.

Taikisha has introduced the Electronic Manifest scheme, which has been promoted by the Ministry of the Environment since 2009 with the purpose of ensuring suitable disposal of industrial wastes. Taikisha’s current introduction rate is 97%.

Suitable Waste Management

Efforts for Freon Management

In compliance with the Fluorocarbons Recovery and Destruction Law that came into force in April 2015, each business office creates Freon Collection Control Sheets and manages the status of filling, collection and suitable disposal of Freon; process management system. In addition, Taikisha draws up Freon collection plans and procedures in the Site Environment Control Plan and endeavor to prevent Freon leaks and other accidents.

Freon Management

Collection and Management of Hazardous Substances

Taikisha uses Hazardous Substances Collection Control Sheets for hazardous substances (lithium bromide, etc.) generated during renovation work or other projects. This is a similar procedure to Freon management, and Taikisha carries it out from the design and construction stage upon confirming whether there are any of the substances with its Design Policy Plan and Site Environment Control Plan.

Collection and Management of Hazardous Substances

Environmentally Considerate Procurement Activities

Green Procurement

To lead the Green Procurement described in Taikisha's environmental management vision, it has its unique “Taikisha Guidelines for Green Procurement.” They specify priorities in selecting or purchasing new facilities, systems, working methods, and technologies to help environmental impact reduction in business activities (design and constructions)
(implemented since April 2010).

Green Procurement

Promotion of Paperless Operations with OnLine Purchasing System

Taikisha has been promoting its online purchasing system for indirect materials, TOPS, so as to reduce the cost of office stationery and improve office work efficiency through a centralized purchasing approach. It enables Taikisha to carry out purchase requisition paperwork free of charge through online purchasing and to drastically reduce the number of account slips used for payment.

Paperless Operations

Adoption of Carbon Offset Products

Taikisha selects office supplies for its construction site offices from among the carbon offset applicable items so that Taikisha can help reduce environmental impacts. For example, Taikisha’s procurement helps to preserve forest ecosystems by choosing products for the Yamanashi Prefectural Forest Global Warming Prevention Project in Yamanashi Prefecture.
