    Current state of the art biotechnological strategies for conversion of watermelon wastes residues to biopolymers production: a review
    (Elsevier, 2021-12-14) Awasthi, Mukesh Kumar; Kumar, Vinay; Yadav, Vivek; Sarsaiya, Surendra; Awasthi, Sanjeev Kumar; Sindhu, Raveendran; Binod, Parameswaran; Kumar, Vinod; Pandey, Ashok; Zhang, Zengqiang
    Poly-3-hydroxyalkanoates (PHA) are biodegradable and compostable polyesters. This review is aimed to provide a unique approach that can help think tanks to frame strategies aiming for clean technology by utilizing cutting edge biotechnological advances to convert fruit and vegetable waste to biopolymer. A PHA manufacturing method based on watermelon waste residue that does not require extensive pretreatment provides a more environmentally friendly and sustainable approach that utilizes an agricultural waste stream. Incorporating fruit processing industry by-products and water, and other resource conservation methods would not only make the manufacturing of microbial bio-plastics like PHA more eco-friendly, but will also help our sector transition to a bioeconomy with circular product streams. The final and most critical element of this review is an in-depth examination of the several hazards inherent in PHA manufacturing.

    Myco-biorefinery approaches for food waste valorization: Present status and future prospects
    (Elsevier, 2022-07-09) Awasthi, Mukesh Kumar; Harirchi, Sharareh; Sar, Taner; VS, Vigneswaran; Rajendran, Karthik; Gómez-García, Ricardo; Hellwig, Coralie; Binod, Parameswaran; Sindhu, Raveendran; Madhavan, Aravind; Kumar, A.N.

    Increases in population and urbanization leads to generation of a large amount of food waste (FW) and its effective waste management is a major concern. But putrescible nature and high moisture content is a major limiting factor for cost effective FW valorization. Bioconversion of FW for the production of value added products is an eco-friendly and economically viable strategy for addressing these issues. Targeting on production of multiple products will solve these issues to greater extent. This article provides an overview of bioconversion of FW to different value added products.

    Organic waste recycling for carbon smart circular bioeconomy and sustainable development: a review
    (Elsevier, 2022-07-15) Awasthi, Mukesh Kumar; Yan, Binghua; Sar, Taner; Gómez-García, Ricardo; Ren, Liheng; Sharma, Pooja; Binod, Parameswaran; Sindhu, Raveendran; Kumar, Vinod; Kumar, Deepak; Mohamed, Badr A.; Zhang, Zengqiang; Taherzadeh, Mohammad J.
    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.
