Technology development related to environmental conservation

"Biomass gas power generation" has been put to practical use in order to effectively utilize plant waste materials (biomass) such as mowing grass and pruned branches of trees and thinning materials generated from Expressway.

Initiatives for the future of the environment

We have set up quick chargers for electric vehicles at 16 resting facilities in our jurisdiction and are making efforts to ensure that customers using electric vehicles can use the Expressway with peace of mind. We plan to continue the maintenance in the future.
