Interpretive Summary: This paper reports an economic analysis of building a plant to process waste from a cotton gin for use as a livestock feed. The analysis is assuming no plant or building exists (i.e., a totally new facility from ground up). The operational design and layout of the plant is based on the COBY process. The COBY process is a USDA-ARS patent process (Pat. No. 6,383,548) for adding value to cotton byproducts. Four plant models are reviewed in this paper ranging in production capacities from 4 to 16 tons per hour. The plants are designed to use both cottonseed and cotton gin byproducts in the making of feed products with varying amounts of fiber, protein, energy, and fat. The costs of production range from $39 to $58 per ton. Overall, the paper supplies needed information on new and developing technology.

Technical Abstract: Extrusion processing can be used on cotton gin by-product (CGB)to produce livestock feed (roughage) products. Using the economic-engineering approach, estimates of unit processing cost for CGB livestock feed products were developed, indicating economies of size, with average per-ton cost as low as $39/ton.
