Research On Risk Identification And Waste Exchange Price For Eco-industrial Park

Industry provides many kinds of products and services for human being, but at the same time, it also takes with resources shortage, environmental degradation, ecological crisis and other global issues. Eco-industrial park is an important way to balance industrial systems with resources system, environmental system and social system to achieve sustainable development. which can use resource with high efficience, reuse the waste, encourage the reduced usage of toxic and hazardous substances, and reduce the harm impact to environment by industry. with the further development of Eco-industrial park construction and operational practices , they faces many problems needed to be solved. This article focuses on risk identification, CO₂ reuse and waste exchange price with innovative research.A risk identification and screening method for Eco-industrial park based on HHM (Hierarchical Holographic Modeling) was proposed to mainly deal with the complex features of the risk characteristics of Eco-industrial park. Six aspects of risk scenarios of Eco-industrial park were analyst form stakeholders, types of loss, life cycle stage, time dimension, structure relationship and Irresistible factors, and risk screening by four steps of Preliminary filtration, filtration and evaluation with double standards, multiple criteria evaluation, and quantitative rating based on the Bayesian formula. This method can help decision makers using the limited resources, energy and manpower to focus on the prevention of key risks.Reusing of CO₂ in Eco-Industrial Park was also discussed. Firstly, current situation of China's industrial carbon emissions was analyzed and a overall framework of CO₂ emissions reduction was proposed. Then, 3R principles of circular economy was used to analyze the CO₂ reduction ways in the reduction, reuse and recycling pathways to help it to choice appropriate reduction methods; At last, significance and advantages of using CO₂ to produce micro-algae was described, and technology route, energy consumption and carbon estimates of using micro-algae to produce bio-diesel were discussedA pricing model of waste exchange in Eco-industrial park was built. Firstly, the status of China's industrial waste and the main dealing approach was analyzed, and then, the waste exchange processes and the main factors of exchange price were discussed, which including the nature of waste, cost of waste disposal, prices of alternative raw material, investment costs, investment income, policy, etc. A pricing model was proposed based on this main factors, and model solution was also discussed. At last, the application of this model was illustrated by a numerical example. This model can help to develop a waste exchange price for Eco-industrial park to achieve the maximize revenue and improve economic, social and environmental benefits.
