Law on Recycling of Construction-Related Materials
(Construction Material Recycling Law)

  I. Purpose

The Law on Recycling of Construction-Related Materials (Construction Material Recycling Law), put into force in May 2002, aims to promote sorting and recycling of waste concrete, asphalt and other materials that are discarded in the process of demolishing buildings.

II. Outline of the Law

The Construction Material Recycling Law promotes recycling by making it obligatory that designated construction materials used for constructions of the specified size or larger are sorted and demolished at the construction site and resulting wastes are recycled.

(1) Construction works to be regulated
Constructions that meet the following standards must be sorted and demolished. The client is required to make a notification.

Type of construction

Standard size

Demolition of a building

80 m2 or more (total floor space)

Construction of a new building or extension

500 m2 or more (total floor space)

Renovation work, etc.

Contracting fee (100 million yen or more)

Civil engineering work, etc.

Contracting fee (5 million yen or more)

* "Building" refers to those specified in the Building Standards Law.


(2) Designated construction materials that must be sorted, demolished and recycled

Designated construction material

Type of industrial waste

Example recycling facilities*1

Recycling method

Concrete

Construction waste

Crushing facilities

Use as a (raw) material

Construction materials consisting of concrete and iron

Construction waste, scrap metal

Crushing facilities

Use as a (raw) material

Wood (wood generated in construction)

Scrap wood

Crushing or incineration facilities*2

*4

Asphalt concrete

Construction waste

Crushing facilities*3

Use as a (raw) material

Notes:
*1 Transferring waste to a recycling facility after selection at a facility other than recycling facilities is also permissible.
*2 It is permitted to reduce (incinerate) wood in a proper facility if recycling is difficult, as in cases where the construction site is more than 50 km away from the nearest recycling facility.
Although crushing facilities designed to process wood into a form suitable for thermal recycling are permissible, a higher priority should be given to transportation of wood to a crushing facility intended for using wood as a (raw) material.
*3 Limited to facilities that are capable of crushing asphalt concrete.
*4 Permissible forms of recycling are: [1] Use as a (raw) material and [2] Thermal recycling. The order of priority is [1] and [2].
