Green design of biodegradable packaging films via renewable coffee waste and PVA matrix tuning

Key Points

• This research aims to create biodegradable packaging films using renewable coffee waste and optimize the PVA matrix for improved properties.
• Developed biodegradable films using coffee waste as a reinforcement material.
• Tuned the PVA matrix to enhance film properties.
• Evaluated the performance of the films in terms of biodegradability and mechanical strength.
• The modified films showed improved biodegradability compared to traditional plastics.
• Mechanical strength of the films was optimized with varying PVA concentrations.
