In this report various methods to promote the resource recovery of industrial organic wastes were applied and estimated through both environmental and economic feasibility studies. In addition, material properties of the industrial organic wastes were compared with current regulation or quality standards. And social and hazardous issues of the current technologies were analyzed to consider its application. Industrial organic wastes described in this study primarily include organic sludges (e.g. wastewater sludge) from food and beverage manufacturing as well as slaughter wastes.
In conclusion, the use of industrial wastewater sludges as a refuse derived fuel (RDF) was considered by finding the similarity with the combustion characteristics of sewage sludges. Also, the anaerobic co-digestion of industrial organic wastes with municipal wastes such as food waste is suggested as a strategy to improve the efficiency of digestion and promote the energy recovery of industry-derived wastes.
For the economic cost-benefit analysis we assumed that electricity and steam were produced by using the biogas generated from the anaerobic digesters. Further we assume that the production of biogas was conducted by two alternatives: co-digestion and separate-digestion. The first alternative is the case in which a co-digestion facility is built and both the industrial organic wastes and the municipal wastes are managed together in a single facility. On the contrary, the second one means producers build separate facilities which manage each wastes separately. The economic cost-benefit analysis
