Product service system is a sustainable concept aimed at providing sustainability of both consumption and production. It focuses on providing a combination of products and services to meet specific customers need promoting higher profit than products alone. However, since the environmental problem has become one of the most serious issues of the world, the majority of the PSS's researches are now focused on sustainable design, using PSS as an effective way to improve the material utilization. These researches are biased to the original definition of this system. This paper is devoted to evaluate the relationship between the PPS's social demands, consumer demands and company demands, providing a possible way to balance demands of these factors. This article exhibits a discussion upon a case study of laundry service. Previous researches in this field have suggested that the laundromat(self-service laundry place) is more sustainable than the home-based washing service in consumers' homes in both consumptions and productions. However, this situation may only make sense amongst crowded residential areas, where in small towns domestic washing machines might be more sustainable in terms of development and fulfiiling customers' needs. In order to balance different demands in the laundry service, they could be combined into a new service type, and provided customized services for different clients.
