Bioglycerol, with its growing production as a co-product of biodiesel, is an attractive low-cost feedstock for the synthesis of platform chemicals by microbial fermentation. 2,3-butanediol (2,3-BDO) is amongst the top biorefinery platform chemicals that can be produced by glycerol fermentation. RESULTS The `Circular Economy' concept is demonstrated by converting the by-product bioglycerol using a cell-free extract of Enterobacter aerogenes NCIM 2695 (National Collection of Industrial Microorganisms, NCIM), yielding 22 g L-1 2,3-BDO, in 96 h, 98% atom economy and 0.4 g/g E factor. The cell-free bioglycerol conversion to 2,3-BDO was proved using a modified procedure for determining glycerol dehydrogenase enzyme assay by protein analysis and it was also shown to be cell-bounded. CONCLUSION Our study offers an effective utilization of the leftover material (i.e. cell-free extract) that biocatalysed C3 to C4 diol, which adds value to the overall economics of the process using only crude glycerol (C3) itself as a fermentative medium.&lt;/p&gt;

	One of the finest approaches towards sustainable waste management is its effective valorization to value-added products (VAPs). Waste valorization is garnering considerable attention since it delivers substantial advantages, including environmental stability and a sustainable and viable platform for producing different VAPs. One such VAP is the poly gamma glutamic acid (&amp;amp; gamma;- PGA), an extortionate biopolymer known to date. Its exorbitant cost is the main barrier preventing &amp;amp; gamma;- PGA from becoming commercially viable. Hence, the key to the successful commercialization of &amp;amp; gamma;- PGA is its sustainable and cost-effective production. In the present study, the ability of Bacillus paralicheniformis NCIM 5769 to utilize molasses for &amp;amp; gamma;-PGA production with minimal nutrients was investigated. Results showed that 30% molasses combined with 2% ammonium nitrate was the optimal medium for &amp;amp; gamma;-PGA production. Additionally, the anti-drought activity of the synthesized &amp;amp; gamma;-PGA was evaluated on wheat plants showing significantly higher shoot length, biomass content, and germination rate compared to the control group. These findings suggest that &amp;amp; gamma;-PGA produced from molasses has the potential to be used as a drought mitigator in wheat plant, thereby achieving the mission of circular economy and sustainable development goal (SGD) 12, i.e. pursuing sustainability patterns for consumption &amp;amp; production.&lt;/p&gt;

	Spent lithium-ion batteries (S-LIBs) are typically discarded in landfills after their lifecycle ends, despite containing valuable materials like graphite. While much research focuses on extracting precious metals from the cathode, this study explores the recycling, recovery, and reuse of spent graphite, converting it into reduced graphene oxide (rGO) for electrochemical sensing. The rGO material demonstrated excellent sensitivity to ascorbic acid (AA) in a concentration range of 1 mM to 100 mM at pH 7.6, offering a cost-effective solution for AA detection. The recovered graphite (RG) from S-LIBs and commercial graphite (CG) was first converted into graphene oxide (R-GO, C-GO) and then reduced (R-rGO, C-rGO). This material underwent extensive structural characterization using techniques such as powder X-ray diffraction (PXRD), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), Brunauer-Emmett-Teller (BET) analysis, field-emission scanning electron microscopy (FE-SEM), and high-resolution transmission electron microscopy (HR-TEM). Electrochemical performance was evaluated through cyclic voltammetry (CV), differential pulse voltammetry (DPV). This study underscores the ``waste-to-wealth'' concept and supports circular economy principles by transforming electronic waste into a valuable resource. The LOD and LOQ for both the material R-rGO and C-rGO were calculated as 3.055 mM, 10.18 mM, and 3.41 mM, 11.36 mM, respectively. The rGO-based sensor not only promotes sustainable recycling but also offers a low-cost, high-performance solution for ascorbic acid detection, with potential applications in food quality monitoring, medical diagnostics, and the cosmetic industry.&lt;/p&gt;
