Tourism management and industrial ecology ----a case study of food service in TaiwanContents Introduction Methods Results ConclusionsIntroduction Tourism development has become a major policy of the government of Taiwan to increase employment and economic growth. However, tourism has long been regarded as having environmental impacts. The main purpose of industrial ecology is to evaluate and minimize impacts from economic activities.Industrial ecology：Industrial ecology (IE) is the means by which humanity can deliberately and rationally approach and maintain sustainability, given the continued economic,cultural and technological evolution.It is a system view in which one seeks to optimize the total materials cycle, from virgin material to finished material, to component, to product, to obsolete product and to ultimate disposal Relation: The application of industrial ecology within tourism was investigated to enhance the environmental management of catering. Industrial ecology has become an important tool for linking industrial activity and environmental and social sciences.MethodsBoxed food analysis {meal boxes are inventoried with life cycle assessment (LCA)}Material flow analysis (MFA)Results The average weight of cardboard, PS, and PP meal boxes is 21.3, 5.1, and 27.2 g/piece, respectively. A life cycle inventory analysis was then carried out within Taiwan and the final results were shown in Table 1.CategoriesAir pollution--- NOx, SOx, CO2, CH4 Environmental pollutionWater pollution--- COD, BOD, SSWaste generation---PS meal box, PP meal boxThe available data for calculating the environmental cost of per meal box production were surveyed as far as possible and are shown in Table 2 The total environmental cost of per meal box production was calculated with the available data list in Table 2 and the final results are shown in Table 3.ConclusionsFirst, in terms of energy and material requirements, the PP meal box production needs more energy, petroleum, coal,
