Efforts for Reducing Waste

Ensuring Garbage Separation and Zero Emission Activities

Kumagai Gumi strives to reduce emitted waste by ensuring that it is properly separated.
We also promote the 3Rs (recycling, reduction, and reuse) for waste, as well as zero emission activities to reduce our amount of final disposal as much as possible.

We will reduce the composite waste emissions at all of our work sites by fiscal 2020, as indicated below.
- Target for building work: Composite waste emissions of less than 10 kg per m2 of total floor area
- Target for civil engineering work: Composite waste emissions of less than 0.5 t per 100 million yen of construction costs
