The study deals with Industrial Symbiosis (IS), a term used to describe a network of diverse organizations that make use of different by-products to improve their facility to achieve common goals, improve environmental conditions or improve business and technical processes. Industrial symbiosis is understood as a technological material as well as a social relationship between so-called social actors, which are involved in the exchange of secondary resources.
The author proposes a model for the evaluation of the possibilities to establish such industrial symbiosis with a study benchmark of seven industrial symbiotic examples used to build a qualitative multi-criteria decision model for the evaluation of the industrial symbiotic network model. With the data obtained from the best-known industrial symbiotic cases in the world, the author examines the importance of social actors’ involvement in industrial symbiosis both in their industrial and non-industrial technological processes.

During the last two decades, increasingly pushing constraints of an economic and environmental nature have appeared. Global warming, soil impoverishment, etc., are worrying facts that forced governments to pledge positions to limit human impact on the environment. The most notable change was undoubtedly the implementation of management systems within organizations, aiming at reaching a sustainable situation. The outputs of each integrate firm becomes the inputs of another. The integrate firms are in a network of services, by-products, and energy flows. That would make them dependent on each other. The firms can also share ancillary services, such as transportation, landscaping, and waste collection, and share in the management of their utilities, such as energy, water, or waste-water treatment. Every day we hear different reports on increasing air pollution, the environment and the pessimistic predictions of scientists regarding the expected state of the environment, and the problem of oversized populations in the future. We are aware of all that. We have everything we need; the impact on the environment, however, is not such a burning topic. Is this exact? To be able to understand why it is necessary to invest in ecology and include it in our daily lives, we must first know the concept of sustainable development, which is introduced in the first part of this study. This is the theoretical framework that defines objectives, which must be achieved, so that children can live decently, at least as good a life as the previous generation. To achieve a better...
