Technical efficiency measures of industrial symbiosis networks using enterprise input-output analysis

In this paper, we develop the concept of technical exchange efficiency of ISNs and develop a measure of such an efficiency. This measure is computed by using an input-output approach at the enterprise level, modelling symbiotic flows within ISNs. A case example is discussed in order to show the practical applications of technical exchange efficiency of ISNs. In particular, technical exchange efficiency of ISNs can be useful in order to drive the development of existing ISNs and to design new industrial systems exploiting the IS approach.
