Agri-Food Waste Valorization in a Circular Economy: Biomolecules and Bioproducts

Agri-food processing residues are end-products emerging after food and industrial processing operations. These waste products are a goldmine, as they possess valuable organic matter such as complex carbohydrates, proteins, and phenolic compounds that can be diverted towards high-value products.

This book covers biomolecules and bioproduct synthesis from agricultural residues with a circular economy approach.It explores the benefits of adopting a sustainable approach, including reducing waste sent to landfills, decreasing reliance on other feedstocks, and potentially reducing pressure on resources used for food production. It also provides valuable insights into emerging trends and technologies for valorizing both agricultural and food waste.

With a blend of technological insights and comprehensive coverage of the potential for agri-food waste valorization, this book will be suited for industry professionals and students seeking to explore the potential benefits of a circular economy.

Key Features:

• Presents a critical analysis of agricultural and food processing waste, their environmental impacts and scopes of valorization in the context of a circular economy • Discusses the up-to- date literature survey of agri-food waste valorization technology • Includes applications of nanotechnology and artificial intelligence in extraction of value-added products from organic waste
