%X Emergy analysis is a new analysis methodology, which can assess a system from the resource utilization and environmental effect. In this paper, the principles of emergy analysis, a new analysis method on energy consumption, are introduced. In order to extend the application range, the model of emergy analysis on industrial multi-product systems is established, based on the fundamental principles of energy conservation and emergy conservation. Joint indices and weighted average indices are proposed, which are designed with the aid of the energy consumption ratio used as the distribution coefficient. Joint indices give the indices for co-generation systems, while weighted average indices indicate the indices if each individual system produces one product. When joint indices are better than weighted average indices, the co-generation system is preferred. Two systems of heat and power co-generation for garbage burning are employed as a case study to prove the efficacy of the model, and compared with the traditional cogeneration system which uses coal as the fuel to show the advantages of emergy analysis.
