When class X student Hetal Vaishnav saw that ragpickers were not picking up waste packets made up of multilayer plastic, she found that recycling companies avoided buying multilayer film plastic waste from them as it cannot be reused or recycled. Hetal then spent months to innovate upon a process to deliver an innovative material that is “sustainable to water, has good nail- and screw-holding capacity, and has features that are better than MDF (Medium-density fibreboard) and plywood.”. This let her use multilayered and metallised plastic used for packaging wafers and chewing tobacco. "I got a certificate from Lincoln Lab a few days ago," Hetal said on telephone from Rajkot. Planet 25636 Vaishnav was named for her contribution to the environment.
