Three-layer business model canvas of oil-water separation equipment in restaurants and food processing factories

A three-layer business model canvas was applied to clarify the environmental, economic, and social impacts of introducing oil-water separation equipment (OWSE) used in restaurants and food processing factories. Introducing high-performance OWSE can change the social structure of manufacturers and residents of sewerage development areas and provide economic benefits to companies. Based on the data of a ramen restaurant in Miyagi, Japan, evaluated the economic effect of introducing OWSE resulted in the total initial cost and maintenance was 1,032USD/year less than the cost of the sewage fee. Therefore, the proposed equation can be used to evaluate the economic effects of introducing OWSE.
