[Display omitted] • Overview of challenges and opportunities of low carbon circular bioeconomy. • Development of low carbon circular bioeconomy were discussed. • Co-evolution of ecosystems, technologies, business strategies and user practices was analyzed. • Overview of value-added products production from these substrates were review. • Metabolic pathway of acidogenic fermentation was reviewed. The development of sustainable and low carbon impact processes for a suitable management of waste and by-products coming from different factors of the industrial value chain like agricultural, forestry and food processing industries. Implementing this will helps to avoid the negative environmental impact and global warming. The application of the circular bioeconomy (CB) and the circular economic models have been shown to be a great opportunity for facing the waste and by-products issues by bringing sustainable processing systems which allow to the value chains be more responsible and resilient. In addition, biorefinery approach coupled to CB context could offer different solution and insights to conquer the current challenges related to decrease the fossil fuel dependency as well as increase efficiency of resource recovery and processing cost of the industrial residues. It is worth to remark the important role that the biotechnological processes such as fermentative, digestive and enzymatic conversions play for an effective waste management and carbon neutrality.

[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.
