Paper Abstract

As manufacturing industries become more cognizant of the ecological effects that their firms have on the surrounding environment, their waste streams are increasingly becoming viewed not as materials in need of disposal, but rather as resources that can be reused, recycled, or reprocessed into valuable products. Within the food processing sector are many examples of biological and organic processing residues. Alternative disposal methods for these manufacturing waste streams are increasingly being investigated. Direct shipping, blending, extrusion, pelleting, and drying are commonly used to produce finished human foods, animal feeds, industrial products, and components ready for further manufacture. Computer modeling and simulation can aid in these value-added endeavors. This paper discusses a strategy that can be used when constructing computer models for bio-organic processing streams. Not only do macroscale process flows need to be considered, but individual constituents, on a micro-scale, are also essential in order to develop appropriate models. The development heuristics and hierarchies discussed here can be applied to various liquid, sludge, or solid materials when simulating processing and reprocessing avenues for specific manufacturing process streams. Thus this methodology is applicable to food processing operations, but many other industrial and manufacturing firms could also benefit from instituting the principles described here.
