Waste generation from groundnut and sugarcane industries are at high alarming rate due to their disposal constraint. These wastes are currently used as a raw material for the production of compost, fuel, alcohol, and paper. Cellulose and its derivatives are being used in many industries like paper, pharmaceutical, and energy owing to its physicochemical properties. Application of cellulose in the leather industry uses cellulose derivatives as finishing chemicals such as nitrocellulose, ethyl cellulose. In the current study, an attempt has been made to find the application of cellulose from groundnut husk and sugarcane bagasse as an auxiliary chemical in leather finishing. Cellulose is extracted from wastes by modified acid hydrolysis method to enhance the yield. Extracted cellulose has been characterized and compared with commercial cellulose sample. From the characterization studies, it confirms that extracted cellulose matched with commercial samples. Extracted cellulose used in leather finishing as an ingredient to upgrade the low-quality leathers, which primarily have grain damages. Cellulose with different concentration of plasticizer has been used in the base coat along with binders and pigments. Finished leathers have been characterized to understand the physical characteristics. From the various analysis, it ascertains that the cellulose has imparted fullness to the finished leather without impacting the aesthetic property. The study provides a better utilization of sugarcane bagasse and groundnut husk wastes in leather industry leading to effective waste management prototype. |
