Valorization of agro-waste of pea: challenges, current developments, and circular bioeconomy

Proper disposal of food waste is crucial for the environment, where valorization of food waste emerges as a promising solution. Pea peel extracts contain high levels of polyphenols, known for their antioxidant and anti-inflammatory properties. Dietary fiber found in pea peel offers numerous health benefits, including improved digestion, weight management, and a reduced risk of chronic diseases. Pea peel can be converted into biodegradable film with desired mechanical and barrier qualities by extraction and processing procedures, which can be used to provide a greener option to regular plastic packaging. Additionally, pyrolysis of pea peel yields biochar, a carbon-rich substance with important agricultural and environmental advantages. The lignocellulosic nature of pea peel enables its transformation into biosorbents. Pea peel biosorbents are a sustainable choice for water filtration and environmental cleanup because of their wide availability, low cost, and environmental friendliness.
