ABSTRACT
The use of plastics for packaging on a global scale has risen considerably in recent decades, resulting in significant negative environmental repercussions. Traditional packaging materials made from fossil fuels are not biodegradable and cause long-lasting pollution, harming ecosystems. As concerns about environmental sustainability and waste management grow, the demand for eco-friendly packaging alternatives that break down naturally is increasing. The agro-food industry, which includes agriculture, food processing, and distribution, produces large quantities of organic waste. This waste consists of agricultural leftovers, peels, husks, shells, stems, seeds, and byproducts from food processing. Poor disposal of this waste leads to environmental issues like greenhouse gas emissions and contamination of soil and water. To address the urgent need for sustainable packaging, researchers and industries are focusing on repurposing agro-food waste to create biodegradable packaging materials. The idea of converting these organic residues into biodegradable substances is gaining traction due to their potential to reduce waste, lower environmental impact, and promote circular economy practices. Biodegradable packaging materials offer a promising solution since they naturally break down over time, preventing the accumulation of plastic waste in the environment. Various biodegradable materials, such as polylactic acid (PLA), polyhydroxyalkanoates (PHA), films made from starch, cellulose derivatives, and chitosan, have demonstrated the potential to replace traditional plastics in packaging applications.
