Quantitative environmental risk assessment for the iron and steel industrial symbiosis network

摘要: An industrial symbiosis network consists of physical material exchanges among members that have materials, energy, and by-products interaction with one another. Emergent accidents in a complex may cause secondary or higher order events nearby unit give rise to series environmental risks, leading negative effects on the environment. The iron steel for local exchange has potential risk due its numerous hazardous materials pollutants. This paper proposes quantitative framework an mapped realistic situation 2012. assessment includes individual node environment transmission between nodes. results demonstrate without symbiosis, coking plant is at high level followed by sintering, ironmaking, steelmaking, stainless steel, sewage treatment thermal power plants. However, network, ironworks-thermal link highest propagation coefficient (0.104). With symbiotic transmission, processing increase priority, whereas other nodes remain previous levels. Consequently, remains moderate spite index increases (average from 31.95 36.14). focus risks whole will provide mitigation strategies benefit management park.
