Key points of the Construction Recycling Law

In recent years, the amount of waste generated has increased, and problems related to waste disposal, such as tightness of waste in landfill and improper disposal of waste, have become more serious. Concrete lumps, asphalt and concrete lumps, and construction waste generated during construction work accounts for approximately 20% of the total amount of industrial waste discharged and final disposal (fiscal 2001), and accounted for about 60% of illegal dumping (fiscal 2002). In addition, buildings in the 1940s have reached the renewal period, and the amount of construction waste is expected to increase in the future. As a solution, the Construction Recycling Law was enacted in May 2000 in order to recycle and reuse these wastes from the viewpoint of ensuring effective use of resources.

The Construction Recycling Law (official name "Law Concerning the Recycling of Materials Related to Construction Work") was fully enforced on May 30, 2002. Under this law, "separate dismantling, etc." and "recycling, etc." are required for specific construction materials, and in order to ensure proper implementation, prior notification of construction by the ordering party or independent builder and demolition contractors A system for registration system, explanation and reporting between ordering parties and contractors, contract procedures, etc. has been developed.

For demolition work pertaining to buildings, etc. using specified construction materials or new construction work that uses those materials for their construction, and whose scale is greater than the standard, the ordering party or independent builder must notify The Mayor of Yokohama about certain matters at least 7 days before the start of construction. In addition, if public institutions such as the national government do so, you will be notified.

The following four specified construction materials are specified by the Construction Recycling Law.

1. Concrete
2. Construction materials made up of concrete and iron
3. Wood
4. Asphalt concrete
