Coordinated regional waste recycling (Kyushu region)

Streamlining the Waste Material Flow

Before this initiative, multiple factories contracted the same waste disposal operator individually to collect factory waste. Now, waste is collected from those factories using one large truck, thereby eliminating wasted energy and achieving 100% load efficiency. The efficient use of large trucks, which have a comparatively low degree of capacity utilization, also benefit the waste disposal operators, who can now use smaller trucks—which have a higher turnover rate—for other uses. Furthermore, by abolishing weekly waste collection that took place regardless of the amount of accumulated waste, and establishing a system in which collection occurs only when a truckload of waste has accumulated at each factory, the number of required truck trips as well as CO2 emissions have been reduced.
