Researchers at Washington University in St. Louis have developed a new biodegradable plastic, called LEAFF, that mimics the structure of a leaf. By embedding cellulose nanofibers between two layers of bioplastic, they created a material that is strong, durable, and compostable. LEAFF exceeds the strength of traditional petrochemical plastics and offers low water and air permeability, making it ideal for food packaging. The material is also printable, reducing the need for separate labels and packaging costs. The team is working on technologies to convert agricultural waste into feedstocks for bioplastic production, which could create jobs and new markets. LEAFF has the potential to be a scalable, sustainable alternative to traditional plastics, addressing the $23.5 billion packaging industry’s need for greener options. The study has been published in the journal Nature Communications, and the researchers believe that LEAFF could play a significant role in reducing plastic waste and pollution.
