Bio-GenerationTM - a Solution to Gin Waste Disposal

Challenges abound for cotton gins in the present era, not least of which is the disposal of by-product from the ginning process. Of particular challenge is disposition of hulls, sticks, motes and leaves. Options currently available to ginners are distribution by spreading of the by-product directly in the fields, composting as a soil amendment for the same fields, or as a feed stock for commercial animal operations. Direct distribution adds little nutritional value to the field, thus it is strictly a method of disposal, adding cost to the ginning operation. Composting prior to distribution does add agronomic value but does not typically generate much, if any, revenue for the gin. For immediate disposal, composting is a poor option, unless it takes place remote from the gin site, adding yet more cost.   The feed stock market has been the only viable revenue source from sales of by-product, but that market is limited and in some regions has disappeared altogether. This paper introduces an alternate solution for gins to dispose of their by-product, simultaneously generating power to operate the disposal system and provide electricity and heat for further processing opportunities.
