Industrial Symbioses: Bi-objective Model and Solution Method

Abstract

The concept of industrial symbiosis is interesting because it allows a significant waste reuse. Indeed, when an enterprise cannot more reduce its wastes nor reuse, it may be beneficial to sell those wastes to other factories for which they will be raw materials. However, to achieve this, it is important to be able to firstly, group complementary enterprises in a same area and secondly, ensure an economic gain to each involved enterprises and a global ecologic gain for the considered area/region. Then, we face a bi-objective problem in which objectives could be conflicting and address this issue, propose a solution to mathematically model this problem and propose a way to solve it. Finally, we will apply this model and its resolution to a real study case located in China.
