“…The selected biomass showed higher moisture content ranging from 73.5 to 93.8% which finds its suitability for HTL process. They had higher volatile matter (61 to 85.6%) and higher cellulose content (21-38%), which favors in increased liquid fuel yield (Divyabharathi and Subramanian, 2022). The characteristics of the selected biomass are given in Table 1.…”

Biomass is a promising renewable energy source for fuel conversion. Hydrothermal liquefaction technology converts biomass into an energy-rich biofuel called biocrude which can potentially substitute fossil fuels. In this study, wet biomass namely water hyacinth, banana pseudostem, banana peduncle, wine waste and beer waste were investigated for biocrude production. The biomass macro molecules underwent anaerobic thermochemical disintegration to yield biocrude in the range of 7.3 to 16% at the hydrothermal liquefaction temperature and pressure of 275 °C and 15 MPa respectively. Wine waste showed higher biocrude yield (16%) among the selected biomass materials with aqueous phase (63%) and char (3%) as by products. The recovered biocrude showed good quality fuel properties similar to diesel and bio-diesel with heating value of about 30 MJ kg -1 . GCMS and FTIR analyses proved the biocrude to be rich in aliphatic and aromatic fuel and chemical derivatives of alkenes, alcohols, ketones and amines which necessitate its potential to drop in advanced fuels and chemicals for supplementing conventional resources.

“…The data-driven methods applied to model hydrothermal treatment processes and predict biocrude and/or hydrochar yield included 18% (50% statistical and 50% ML methods) of all the applications reviewed in the literature (Figure a and Table S9). Among the data-driven models of hydrothermal treatment, 15% were MLR models − and 35% were MPR models ,− (Figure a and Table S9). These models were developed using primary data that involved operational parameters (e.g., temperature, residence time, biomass/water ratio) for multiple feedstocks (organic municipal solid waste, agricultural and forestry residue).…”

Municipal and agricultural organic waste can be treated to recover energy, nutrients, and carbon through resource recovery and carbon capture (RRCC) technologies such as anaerobic digestion, struvite precipitation, and pyrolysis. Data science could benefit such technologies by improving their efficiency through data-driven process modeling along with reducing environmental and economic burdens via life cycle assessment (LCA) and techno-economic analysis (TEA), respectively. We critically reviewed 616 peer-reviewed articles on the use of data science in RRCC published during 2002−2022. Although applications of machine learning (ML) methods have drastically increased over time for modeling RRCC technologies, the reviewed studies exhibited significant knowledge gaps at various model development stages. In terms of sustainability, an increasing number of studies included LCA with TEA to quantify both environmental and economic impacts of RRCC. Integration of ML methods with LCA and TEA has the potential to costeffectively investigate the trade-off between efficiency and sustainability of RRCC, although the literature lacked such integration of techniques. Therefore, we propose an integrated data science framework to inform efficient and sustainable RRCC from organic waste based on the review. Overall, the findings from this review can inform practitioners about the effective utilization of various data science methods for real-world implementation of RRCC technologies.

“…Mandarin (Citrus reticulata) is grown majorly in temperate climate countries (Januário et al, 2021). India produces approximately 31.75 × 10 8 kg of oranges per year on an area of 1.96 ×10 9 m 2 (Divyabharathi & Subramanian, 2022). The fruits are flattened, with loose and rough peels and few seeds, making them easy to consume (Colodel et al, 2018).…”

Oranges account for a majority of the citrus fruit and it is used widely in the juice manufacturing industry. These industries produce a large amount of waste which majorly includes orange peels. As these peels contain a wide diversity of bioactive compounds, they can be utilized in the synthesis of various value-added products which aid in reducing environmental pollution and also address the economic issues. This paper focuses on finding the antimicrobial activity and phytochemical analysis of solvent extraction of peels of Citrus reticulata. The Citrus reticulata peels were dried, ground, and extracted using various solvents like acetone, ethanol, ethyl acetate, and petroleum ether, and their antimicrobial activity was determined against Gram-positive bacteria like Enterococcus faecalis and Staphylococcus aureus and Gram-negative bacteria like Salmonella typhi. Phytochemical analysis was also carried out to know the presence or absence of various bioactive compounds in solvent extraction. Antimicrobial analysis like agar well diffusion assay, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) was conducted and the outcomes acquired revealed that ethanol extract of Citrus reticulata peel was more efficient when compared to peel extracts using other solvents. The phytochemical analysis also showed that ethanol extract showed the presence of more secondary metabolites which can be the reason for the increased antimicrobial activity of the ethanol extract.
