Vulnerability Study of Municipal Solid Waste Resource Symbiosis Network:Based on a Case Study of Zero-Waste City Construction in a City
Municipal Solid Waste Resource Symbiosis Network(MSWRSN)is the best way to achieve zero-waste cities.However,MSWRSN is vulnerable to a wide range of factors.Examples include shrinking demand for recycled resources or changes in standards,the emergence of breakthrough technological innovations,and conflicts of interest arising from serious information asymmetries in markets,technologies and policies.The system often falters or operates abnormally,constraining the construction and development of waste-free cities.On this basis,this study combs the construction background and development process of zero-waste cities in China.The study specifically takes a city in China as an example and introduces the basic situation and results of a zero-waste city construction in that city.After study in that city,a symbiotic network for solid waste resource utilization is constructed and simulation experiments using the MATLAB program is conducted.The results indicate that the city's MSWRSN has not yet developed a nested pattern,and that there are differences in the symbiosis patterns of different industrial chains.Based on the conclusions of the study,it is proposed to manage the vulnerability of MSWRSN management from three aspects,which include promoting informationization,focusing on core business operations and developing technological innovation.
