A team at the University of Illinois Chicago has created a new plant-based bioplastic. It’s designed to replace conventional plastic bags. Unlike low-density polyethylene bags, which can take hundreds of years to decompose, this new material breaks down in about one month.
Made from natural plant materials like cellulose and lignin, the bioplastic aims to match the strength and performance of existing plastic bags. The team reports these findings in a recent study published in Chemical Engineering Journal.
Most plastics today come from fossil fuels. They are often discarded into landfills or pollute the environment. Only a small percentage is recycled, leading to pollution and harm to wildlife. The new bioplastic offers a sustainable alternative by using renewable plant materials.
The researchers used cellulose and lignin from Miscanthus, a type of grass. They also tested lignin from other plants like poplar, pine, corn, and sugarcane. They dissolved these into a special salt. Then, they formed thin films by cooling and drying the mixture carefully. Tests showed that the bioplastic has similar strength, flexibility, water resistance, and UV protection as traditional plastics and eco-friendly market options like Biobag.
Most importantly, the bioplastic decomposes quickly in soil: about one month. This makes it a promising eco-friendly substitute. The team plans to study how to improve its manufacturing, flexibility, and breakdown process.
They aim to scale up production and explore commercial uses. This innovation could help reduce plastic pollution and protect the environment.
