Valorization of Cotton Gin Trash through Thermal and Biological Conversion for Soil Application

Cotton gin trash, the by-product of cotton ginning industry which is produced in large quantities every year, can be utilized as feedstock for deriving high quality organic materials such biochar, compost and co-composted derivates improvement soils’ key physical, chemical biological properties. This first report trash was both thermally biologically converted at same time into biochar (BC), (C) co-compost (Coc), their effects on soil properties plant performance were examined. In order to find optimum rate, products used amendments a greenhouse experiment 2.5 t ha−1, 5 ha−1and 10 ha−1 rates. All contributed improving provided agronomic benefits plants, however plants (radish var. Cherry belle) showed significantly (p < 0.05) better growth attributes almost 315% increase biomass yield observed when (10 ha−1) applied soil, thus suggesting its role compensating fertilizer application. Amendments (2.5 5.0 considerably increased parameters; however, differences between not so significant. As result, replenishing with Coc (5 regular basis promote improve qualities over time.
