Sustainable blueberry waste recycling towards biorefinery strategy and circular bioeconomy: A review

[Display omitted] •Blueberry waste as potential resource for value addition end product recovery are discussed.•Sustainable resource recovery and ecofriendly approach are reviewed.•Recent trends and possibilities on blueberry biorefinery are mentioned.•Challenges in blueberry waste resource recovery and applications are appraised.•Circular bioeconomy aspects and regulatory issues of blueberry waste are discussed. Waste valorization using biological methods for value addition as well as environmental management is becoming popular approach for sustainable development. The present review addresses the availability of blueberry crop residues (BCR), applications of this feedstock in bioprocess for obtaining range of value-added products, to offer economic viability, business development and market potential, challenges and future perspectives. To the best of our knowledge, this is the first article addressing the blueberry waste valorization for a sustainable circular bioeconomy. Furthermore, it covers the information on the alternative BCR valorization methods and production of biochar for environmental management through removal or mitigation of organic and inorganic pollutants from contaminated sites. The review also discusses the ample opportunities of strategic utilization of BCR to offer solutions for environmental sustenance, covers the emerging trends to produce multi-products and techno-economic prospective for sustainable agronomy.
