摘要：For decades, the industry is a huge consumer of resources, generates waste and has serious impacts on our planet. In order to preserve the environment, new economic models are emerging including the circular economy. Circular economy is a system that fits with sustainability and aims to reduce both resources consumption and waste production. Among the components of circular economy, industrial ecology is the collaboration of industries on a territory in order to exchange materials, water or energy through industrial symbiosis. Industrial ecology and industrial symbiosis are more and more present in the literature. However, most of articles in the literature focused on the strategic decision level. In this paper, we focus on tactical decisions, and investigate production planning as a lot sizing problem in a collaborative context involving two actors belong an industrial symbiosis.
