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 in landfill and improper disposal of waste have become more serious. Concrete lumps, asphalt / concrete lumps, and construction waste generated during construction work accounts for about 20% of total industrial waste discharged and final disposal volume (FY2002). In addition, buildings in the 1940s are undergoing renewal, and construction waste emissions are expected to increase in the future. As a solution to this problem, the Construction Recycling Law was enacted in May 2000 to recycle and reuse these wastes from the perspective of ensuring effective use of resources.

The Construction Recycling Law (officially named "Law Concerning the Recycling of Materials Related to Construction Work") came into effect on May 30, 2002. Under this law, "separate dismantling, etc." and "recycling, etc." and "recycling", and in order to ensure proper implementation, prior notification of construction by the ordering party or independent builder. A system for registration system, explanation and reporting between orderer and contractor, contract procedures, etc. have been established.

For demolition work pertaining to buildings using specified construction materials or new construction works that use those materials for their construction, and whose scale exceeds the standard, the ordering party or independent builder must notify the The Mayor of Yokohama at least 7 days before the start of construction. In addition, it will be notified when a public institution such as the country performs it.

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

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

For specific examples, please refer to "Specific Specific Construction Materials" (PDF: 379KB).

There are four criteria for the type and scale of construction work subject to the Construction Recycling Law. In addition, please confirm in "judgment flow targeted for notification of construction recycling law and supplementary materials" (PDF: 333KB) which listed details about whether it becomes target construction work.

1. In the case of demolition work of buildings: Total floor area of 80 m2 or more
2. In the case of new construction and extension work of buildings: Total floor area of 500 m2 or more
3. In the case of building repair and remodeling (renovation, etc.) of buildings: Contract amount of 100 million yen (including tax) or more
4. In the case of construction work related to other structures (civil engineering work, etc.): Contract amount 5 million yen (including tax) or more
