In this study, the reduction on the environmental load by the replacement of conventional toilets with low environmental load toilets at highway service areas in Japan was quantified and a cost-benefit analysis concerning introducing low environmental load toilet such as waterless urinals and urine diversion toilets were performed. As for the results, the environmental loads from the service area, water consumption and energy consumption were reduced greatly by introducing low environmental load toilets. In addition, it is found that this system can be easily paid back in 3 years regarding the burden of the energy and cost when it is introduced into large service areas where the wastewater is treated by the sewage system.
