“…This metric selects the most desirable solution that satisfies all of the given objectives. For the MED-TVC system, an equal weight is assigned to all four objectives, and hence, this approach ensures a fair and unbiased decision-making process for selecting a single point from a number of equally competitive optimal points of a Pareto front. , The detailed algorithm in MS Excel can be found in ref .…”

Seawater desalination is consistently gaining research interest, as water scarcity looms globally. Multieffect distillation with thermal vapor compression (MED-TVC) has emerged as a promising solution to the freshwater scarcity problem. In this contribution, we put forward a way to gain physical insights into various feeding patterns of MED-TVC and identify a suitable pattern to treat saline water effectively. For this, a dynamic model for a MED-TVC with parallel cross feed (PCF) is first formulated and then validated it with data sets of two different plants showing excellent matching. This validated model is further extended for dynamic multiobjective genetic algorithm-based optimization by framing four conflicting objectives in the aspects of performance ratio (PR), second law efficiency (η II ), freshwater production cost (FWPC), and CO 2 emission. With this, we formulate the technique for order of preference by similarity to ideal solution (TOPSIS) embedded nondominated sorting genetic algorithm-II (NSGA-II). A systematic comparison is presented between the optimal performance of the three feeding patterns, namely, forward, parallel, and parallel cross feed MED-TVC operating under optimal configurations. The relative merits and demerits of each feeding pattern are discussed, and among them, the PCF comes out as the front-runner with minimum cost (FWPC) and emission level and maximum performance ratio and thermodynamic efficiency. This study provides a clear and optimal picture based on the stated objectives and properly guides to choose a suitable feeding methodology for seawater desalination in MED-TVC.

“…Hydrodeoxygenation (HDO) of lignin monomer molecules-vanillyl alcohol and vanillin was conducted over Pd/Ru metal supported graphene oxide nano-catalysts [ 220 ]. This method was directly applied to the chemical transformation of phenolic intermediates generated by photocatalytic cracking to obtain vanillin and p -cresol, which can be formed as a potential biofuel in the future [ 221 ]. To summarize, nano-catalytic technologies are of high importance in the efficient and complete conversion of biomass-derived feedstocks, biowaste, and bio-oil, thus has a promising application in the conversion of HALUB [ 222 ].…”

We conceptualize bioresource upgrade for sustainable energy, environment, and biomedicine with a focus on circular economy, sustainability, and carbon neutrality using high availability and low utilization biomass (HALUB). We acme energy-efficient technologies for sustainable energy and material recovery and applications. The technologies of thermochemical conversion (TC), biochemical conversion (BC), electrochemical conversion (EC), and photochemical conversion (PTC) are summarized for HALUB. Microalgal biomass could contribute to a biofuel HHV of 35.72 MJ Kg−1 and total benefit of 749 $/ton biomass via TC. Specific surface area of biochar reached 3000 m2 g−1 via pyrolytic carbonization of waste bean dregs. Lignocellulosic biomass can be effectively converted into bio-stimulants and biofertilizers via BC with a high conversion efficiency of more than 90%. Besides, lignocellulosic biomass can contribute to a current density of 672 mA m−2 via EC. Bioresource can be 100% selectively synthesized via electrocatalysis through EC and PTC. Machine learning, techno-economic analysis, and life cycle analysis are essential to various upgrading approaches of HALUB. Sustainable biomaterials, sustainable living materials and technologies for biomedical and multifunctional applications like nano-catalysis, microfluidic and micro/nanomotors beyond are also highlighted. New techniques and systems for the complete conversion and utilization of HALUB for new energy and materials are further discussed.

“…According to IEA report if net zero emissions have to be achieved by 2050, then biofuels production should grow at 14% during 2020 -2030 and share of second and third generation biofuels has to be increased to 45% from the current 7% [6]. Table 1 provides a brief comparison of biodiesel with respect to oil yield and biodiesel productivity [7,8]. Recently, production of third generation biodiesel from algae is popular as inferred from Table 1, algae have high oil content with upto 80% of dry biomass weight, high oil yield and productivity, high growth rate where biomass doubles in 24 hours during exponential growth phase.…”

Algae based third generation biodiesel production is a recent advancement in renewable energy due to its minimal land requirements, cultivation in wastelands etc than food stock based second generation biodiesel production. This paper addresses on the study of the optimum yield of biodiesel produced from oxygenic photosynthetic bacteria-based Spirulina Platensis algae by microwave assisted transesterification. Effect of microwave irradiation time which affects the temperature on the extraction of algal oil and simultaneous in-situ transesterification was investigated for biodiesel production. The response surface methodology using Box Behnken Design was used to analyze constituent parameters like catalyst concentration, alcohol concentration and process para meters like microwave time. Results indicate that microwave assisted transesterification yields at 70.7% of biodiesel production with respect to algae dry weight at an optimum of catalyst concentration of 1.6%, with alcohol concentration of 1:9.7 and microwave irradiation time of 3.2 minutes.
