A plant based Leather like material for industrial applications and a process for the preparation thereof
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.

Fruit based leather-like material and a process for the preparation thereof
Disclosed herein is a fruit based leather-like material for application in fancy lifestyle and other consumer product industries. The material may contain upto 90% of fruit fiber. A process for the preparation of the material with different size/thickness ranges is also provided. It essentially involves pulping of the fibrous matter present in waste spoiled fruit, mixing the fruit pulp with polymer as well as other additives, followed by casting and drying. The process is based on zero discharge concept excluding the seed, into the environment. The final material, is flexible and exhibits good mechanical properties, adequate for small consumer products. The unique feature of the technology is that it leads to a value added non-hazardous, eco-friendly product that finds potential multiple industrial applications in textiles, leather, packaging and other life style product industries. The implementation of the process is possible with minimum investment.
