Abstract:
An eco-friendly and flexible vegan leather-like material with good strength is prepared using agricultural  waste such as sugarcane straw, sorghum stem, sorghum straw, rice straw, wheat straw and Indian grass for use in textiles, leather,  packaging and other life style product industries. The method comprises alkali hydrolysis augmented with gelling agent for destruction  of cellulose, lignin and hemicellulose components of the agro waste. The alkaline hydrolysis process involves initial microwave  irradiation based destruction followed by conventional thermo-mechanical heating followed by addition of eco-friendly polymer. The  contents are poured in a mould and dried to yield flexible sheet. The sheets are surface coated employing typical leather finishing  techniques. The disclosed process is based on zero discharge concept without discarding either liquid or solid waste into the  environment. The final vegan leather-like sheet material is non-hazardous, eco-friendly and inexpensive that has Applications in  textiles, leather, packaging and other life style product industries.
