Ecological industrial engineering and eco-efficiency analysis

With the increasing heavy pressure from environment and nature resource, people has taken innovative measures to free themselves from the present irrational economic development pattern, and strongly promoted the development of circular-type and ecotype economy. The main tasks of eco-industrial engineering are to introduce the ideas of ecotype into the design of industrial system based on the theories of circular economy, and achieve the harmony of economic benefit and ecological benefit. In order to gain more effective utilization ratio of resource and lower environment pollution, eco-efficiency combines economy with environment. This paper based on researching eco-efficiency indicators system, points out eco- industrial engineering evaluation methods on account of the eco-efficiency.
