ABSTRACT
The byproducts produced by the cotton ginning process have commonly been referred to as cotton gin trash or waste because of the costs associated with their disposal and their limited value in current utilization applications. However, cotton gin byproducts (CGB) have been the subject of extensive research and have found some limited applications as a roughage in livestock feed, compost material, and as a soil amendment. Typically, all research pertaining to utilization of CGB has evaluated or measured some aspect of the product to determine a desired or needed characteristic pertaining to a specific objective or goal. Cotton gins produce various streams of byproducts due to the design and layout of the equipment used in the cotton ginning process. Historically, the byproducts from the different gin processes are combined into a single waste stream and conveyed to a central location. The objective of this research was to characterize the various parameters of the byproducts coming from the individual waste streams prior to being combined to ascertain if the ginning equipment was sorting the byproducts into components that had more desirable characteristics to potential end users. Results indicated that the extractors along with the lower gin motes, gin stand feeder, overflow separator and lint cleaners produced a product with more desirable characteristics for livestock feeding and fuel utilization than those byproducts from the inclined cleaners and unloading system.
