Industrial Waste Disposal and Recycling

Among the industrial wastes generated at sites where Taikisha performs construction work as the main contractor, Taikisha encourages 4R* activities whereby waste is 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 ratio of 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

Proper Waste Management

All projects in which the main contractor is Taikisha are listed up and the waste disposal status is monitored to ensure the waste is treated properly.
Also, local government permit information on 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 conducted only with the listed agencies.
Taikisha has introduced the Electronic Manifest scheme since 2009. It has been promoted by the Ministry of the Environment with the purpose of ensuring proper disposal of industrial waste. Taikisha’s current introduction rate is 96%.

Suitable Waste Management

Efforts for Freon Management

In compliance with the Fluorocarbons Recovery and Destruction Law, each business office creates Freon Collection Control Sheets and manages the status of filling, collection, and proper disposal of Freon (process management system). When conducting Freon collection work, Taikisha draws up Freon collection plans and procedures and endeavors to prevent Freon leaks and other accidents.

Collection and Management of Hazardous Substances

Taikisha uses Hazardous Substances Collection Control Sheets to manage the collection and proper disposal of hazardous substances (lithium bromide, etc.) generated during renovation work or other projects. Taikisha carries it out from the design and construction stage upon confirming whether there are any substances applicable with its Design Policy Plan and Site Environment Control Plan.

Collection and Management of Hazardous Substances

Environmentally Considerate Procurement Activities

Green Procurement Policy

To lead the green procurement described in Environmental Management Vision, Taikisha strives for preferential procurement and selection of new equipment, systems, working methods and technologies to help reduce environmental impact in business activities (design and construction). Taikisha has determined green procurement items based on its own standards "Taikisha Green Procurement Guidelines", and grasps the results of procurement and conducts periodic reviews on these green procurement items.
(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 has adopted goods with carbon offset credits attached, provided by Yamanashi Prefecture under the Yamanashi Prefecture Project to Combat Global Warming by Forest Utilization, in an effort to promote procurement with consideration for conserving forest ecosystems.
