This reading discussed the industrial symbiosis within Greece. The article goes into depth about the study of spatial allocation patterns. It mentions how there are different levels of eco-industrial networks. These include physical, spatial, economic, and environmental. The spatial scale, as mentioned above, is the main focus of this article. This sector deals with five areas. This includes the industrial park (IP), local (LOC), regional (REG), national (NAT), and global (GLO). These areas define where the producer and recipient are located within Greece. Industrial symbiosis is the relationship between 2 or more firms that exchange their waste as feedstock for the production process, which then forms industrial ecosystems. Industrial ecosystems are made up of eco-industrial ecosystems and eco-industrial networks. This approach helps pollution prevention, which uses materials, processes, and practices to decrease the creation of waste at the source. The main elements of this approach are recycling and the reuse of industrial waste and end-of-life products. Waste can be materials, energy, or water. This approach was researched through case studies within the Greek industry. Research was conducted through achieves of ministry of economics, personal professional experience of authors in the field on environmental industrial controls, and contacts and interviews with administration of a majority of industrial parks in Greece and executives of various businesses. This article researched 455 case studies and 16 eco-industrial networks. Through this research, they were able to identify and document 45 waste types. For the unit of analysis, single cases were used, not entire networks. In the article, special factors that affected spatial allocation of eco-industrial networks were discussed. Physical characteristics of waste, waste compatibility, spatial allocation of waste sources, production capacity of waste by spatial scale, land acquisition cost, labor cost, transportation cost, and behavioral factors are the main special factors that were discussed. For the physical characteristics of waste, it mentions how the transportation of waste heat energy is from power stations, which takes the form of superheated water. For the waste compatibility, it permits its direct use, and mentions how waste from agriculture activities, which can include malt, seed, and residues, can be widely used as raw material in other rural activities. Overall, this article helped define how Greece is using spatial factors and analysis to help determine the correct and most efficient way to handle waste management. Hopefully, through industrial symbiosis, Greece can control their waste management efforts to their best ability.
