Interpretive Summary:

Technical Abstract: Cotton Gin Byproducts (CGB) and Beef Manure (BM) have similar properties that are often explored for soil amendment and bioenergy. This study was conducted to investigate the potential for sustainable utilization of CGB in animal (beef) production, beef manure in crop (e.g., cotton) production, and CGB-BM pellets as sources of energy in both cotton and beef industries. In the current study, different formulations of CGB and BM were pelletized and characterized for nutrient composition as soil amendments. CGB pellets, without manure, were also analyzed for potential integration into animal feeds. Changes in properties relevant to supplementing nutrients in soil and animal feeds (such as moisture, durability, nitrogen, phosphorus, potassium, proteins, fibers, ash, digestibility, etc.) were determined to establish the effects of pelletization on the materials. This work provides guidance on processing CGB and BM for the target applications while also focusing on enhancing the pellet properties for storage and transportation. It is hypothesized that adding BM will enhance nutrient composition and durability of the pellets. The combination of CGB and BM into one product with enhanced properties provide a strong potential for sustainable byproducts utilization and circularity across two industries.
