Our project, Green Plastic, is centered on developing sustainable, biodegradable bioplastics using food and agricultural waste as an alternative to conventional plastic. The challenge we address is the growing problem of plastic pollution, which harms biodiversity, contaminates soil and water through microplastics, and places a heavy burden on waste management systems. Despite increasing awareness, most existing plastics remain fossil-fuel-based or rely on expensive industrial bioplastics that are inaccessible to many communities.
To respond to this challenge, we designed and tested two distinct types of bioplastics. The first is a protein–polysaccharide green plastic, suitable for flexible packaging, made using plant proteins, natural starches, and biodegradable binders. The second is a lignocellulosic green plastic, developed from vegetable peels and plant fibers, which can be molded into rigid products such as plates and bowls. Both materials are non-toxic, compostable, and break down naturally without leaving microplastics.
We demonstrate that sustainable materials can be affordable, scalable, and accessible, offering a practical solution to reduce plastic pollution while empowering communities to be part of the change.
