Construction recycling Plan
Establish nine strategies focused on ensuring the effectiveness ofconstruction resource circulation
Strategy 1 Utilize concrete waste and other
Strategy 2 Utilize woods waste
Strategy 3 Utilize construction mud
Strategy 4 Utilize construction soil(excavated soil)
Strategy 5 Utilize waste for construction materials
Strategy 6 Carry out green procurement in construction work
Strategy 7 Long-term use of buildings etc.
Strategy 8 Build a foundation to support the strategy
Strategy 9 Promote construction recycling in the island area

Tokyo Metropolitan Government
Construction recycling Guideline
Purpose In order to steadily promote the strategy of promotion plan, weset necessary matters concerning the implementation of various
measures concerning construction resource recycling

Scope of application
 Tokyo Metropolitan governments, supervision organizations,

reporting organizations and wards, municipal orders, private works

Point- Creation of Recycling Plan
- Recycling of construction and Demolition Waste- (excavated soil, concrete waste, etc.)- Green procurement in construction work-8-

Trend of Recycled Aggregate Concrete
Recent situation of related standards－ March, 28,2016 Ministry of Land, Infrastructure and Transport(MLIT)“Quality standards by application for recycling of concrete ｗａｓｔｅ”> Recycled aggregate concrete M can be used as a structure of muscle concrete.

－ Jun,2016 Ministry of Land, Infrastructure and Transport(MLIT)“Revised Building Standards Law Notice”> The JIS standard conforming to Building Standards Law was changed from 2003 version to 2014 version.
> It became unnecessary to acquire certification by the minister when using ready mixed concrete using
recycled aggregate H as a structural material.

JIS Standard－ JIS A 5021(March,2005):recycled aggregate H for concrete－ JIS A 5022(March,2006):recycled aggregate M for concrete－ JIS A 5023(March,2007):recycled aggregate L for concreteTokyo Metropolitan Government－ Certification system for quality standards of recycled crusher-run(Fiscal Year 2017)> Tokyo Metropolitan Government (Environment Bureau) certifies the quality criteria of recycled crushed-run
determined by private organizations.
> We also certify manufacturing facilities that meet the certification criteria.

－ Usage of recycled crusher-run> We are promoting the use of recycled crusher-run as roadbed material, infiltration trench material, gravelcompaction material, backing material for retaining walls.
