Kumagai Gumi has set a target of reducing our mixed construction waste discharge rate to 2.0% or less by taking action to cut mixed waste on the way to achieving zero discharge, which is a specific issue laid out in our ESG Initiative Direction. We are focusing on promoting 3R practices (reduce, reuse, recycle), thorough separation of plastic waste, and promotion of green purchasing.

Promotion of 3R practices

Overall 3R Plan
Identification of incoming materials, quantities by product, and available disposal options

Reduce
Proposals to clients and designers at the construction planning stage, followed by implementation

Reuse
Use materials at multiple work sites, primarily materials for temporary use

Recycle
Emphasis on voluntary waste separation activities
(1) Priority outsourcing to superior industrial waste disposal service providers
(2) Education on waste separation
(3) Foremen's meeting activities at construction sites

FY2021 results (Kumagai Gumi only)
Construction mixed waste discharge rate
1.8% (Target: maintain at 2.0% or less)

Enforcement of separation of plastic garbage

A new set of Separation Procedures for Plastic Waste was established in October 2021 to promote the separation, proper disposal, and recycling of plastic waste.

Management system
Operation and management of the Quality and Environment Management System

FY2021 results (Kumagai Gumi only)
Total amount of separated waste plastic
9,600 t
