MUMBAI, India, June 26 -- Intellectual Property India has published a patent application (202641072202 A) filed by Palanki Krishna Murthy; Dr. Kambagowni Venkata Subbaiah; and Andhra University on June 10, 2026, for Controlled Biodegradation Polymer Composition Having Accelerated Carbon Mineralisation And Balanced Functional Properties For Short- Life Molded Products.
Inventors include Palanki Krishna Murthy; Dr. Kambagowni Venkata Subbaiah; and Andhra University.
The application for the patent was published on June 19, 2026, under issue no. 25/2026.
Abstract: The present invention relates to a controlled biodegradation polymer composition suitable for manufacturing short-life moulded products. The composition comprises poly(lactic acid), chemically changed starch, and polyethylene glycol, wherein the combined action of the constituents promotes accelerated carbon mineralization and enhanced biodegradation under ambient environmental conditions. The invention facilitates degradation through moisture-assisted hydrolysis, microbial assimilation, and progressive conversion of polymeric carbon into carbon dioxide without requiring industrial composting conditions or elevated environmental temperatures. The composition exhibits measurable biodegradation in soil and compost environments, accompanied by mass loss, structural evolution, and chemical degradation of the polymer matrix. Structural and chemical changes occurring during biodegradation are characterised through X-ray diffraction and Fourier transform infrared spectroscopy analyses, confirming degradation of amorphous regions and hydrolytic cleavage of polymer chains. The invention further provides balanced biodegradable polymer compositions exhibiting a favourable combination of carbon mineralisation behaviour, environmental degradability, density characteristics, and thermal conductivity suitable for short-life moulded products, wherein selected formulations demonstrate enhanced overall performance under ambient soil and compost conditions. Accordingly, the invention offers a sustainable alternative to conventional plastic materials by combining practical functionality with controlled end-of-life degradation and accelerated environmental biodegradation.
