MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641026421 A) filed by Mr. A Sridhar; Miss. G. Anusurya; Miss. G. Karishma; M. Kishorekumar; and P. Nagulan, Coimbatore, Tamil Nadu, on March 6, for 'development of biodegradable spoons using starch, sugarcane bagasse and rice straw.'
Inventor(s) include Mr. A Sridhar; Miss. G. Anusurya; Miss. G. Karishma; M. Kishorekumar; and P. Nagulan.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to the development of biodegradable spoons using a starch-based biopolymer matrix reinforced with agricultural residues such as sugarcane bagasse and rice straw. The starch, obtained from natural sources including potato, corn, or banana peel, serves as the primary biodegradable polymer and undergoes gelatinization upon controlled heating with water. Finely processed lignocellulosic fibers from sugarcane bagasse and rice straw are incorporated into the gelatinized starch matrix to enhance tensile strength, rigidity, and structural stability of the final product. Glycerol is added as a plasticizer to improve flexibility, reduce brittleness, and facilitate uniform moulding. The blended composition is converted into a homogeneous dough or slurry and shaped into spoons using compression moulding techniques. The moulded products are subjected to controlled drying to remove excess moisture and to achieve desired hardness and dimensional stability. The developed spoons are lightweight, durable for short-term food contact, biodegradable, and compostable under soil burial or composting conditions This invention provides an environmentally sustainable alternative to conventional singleuse plastic cutlery by utilizing renewable starch sources and agro-industrial waste materials. The process promotes waste valorization, reduces environmental pollution, and supports the development of eco-friendly disposable food service products. Keywords: Biodegradable spoons; starch-based polymer; sugarcane bagasse fiber; rice straw reinforcement; glycerol plasticizer; agro-waste utilization; compression moulding; compostable materials; sustainable packaging; eco-friendly cutlery."
