Title: Innovations by Inventor Jean M Mayer
Introduction
Jean M Mayer is an accomplished inventor based in North Smithfield, Rhode Island, with a focus on biodegradable materials. She holds three patents that showcase her innovative approaches to creating environmentally friendly products. Her work is particularly significant in the field of biodegradable plastics, which addresses the growing concern over plastic waste.
Latest Patents
One of her latest patents is a method of producing biodegradable starch-based products from unprocessed materials. This invention discloses a method of preparing and extruding biodegradable starch blends into products without the need for preprocessing steps, such as gelatinizing or destructurizing the starch. By combining unprocessed raw starch with biodegradable copolymers like polyvinyl alcohol (PVOH) or ethylene vinyl alcohol (EVOH), along with a nucleating agent and a plasticizer, the process can be efficiently executed using a twin-screw mixer. This method significantly reduces the cost and time required to prepare and extrude starch-based biodegradable materials, resulting in a product that is substantially completely biodegradable.
Another notable patent involves a method and composition for making biodegradable injection molded parts. This invention utilizes a blend of 30% to 70% cellulose acetate, 10% to 60% unmodified raw starch, and 5% to 35% plasticizer, including glycerols and glycerol acetates. The solid ingredients are combined and fed into an extruder to create pellets or to supply injection molding equipment. The resulting parts can be clear, white, or colorful, depending on the added filler materials, and are characterized by their water resistance, high strength, and biodegradability.
