Summary: The careless usage of fossil fuels is the primary contributor to global warming. Due to urbanization's threat to resource depletion, finding alternatives has become necessary. Four different forms of biofuels are now available as possible replacements, including first-generation biofuels from the edible portion of biomass, second-generation biofuels from the non-edible portion, third-generation biofuels from algal biomass, and fourth-generation biofuels using molecular biology to improve algal strains. This article discusses the importance of second-generation biofuels derived from non-edible biomass and the enzymes involved in their production.

Summary: The transition from gasoline and petroleum-based products to biofuels and green chemicals is a paradigm shift that will lead to the development of the bioeconomy. Biorefineries in countries like Brazil play a crucial role in this transition, with the country generating a significant amount of second-generation biomass and having an attractive consumer market. Technological innovations are still needed to fully unlock the potential of biomass conversion to biofuels and biochemicals, but successful examples such as renewable products for cosmetics and sustainable technologies for pulp production already exist. The RenovaBio Policy launched by the Federal Brazilian Government aims to boost the production and utilization of biofuels and green chemicals in the country.

Summary: The present study evaluated the total energy output and economic feasibility of biodiesel production coupled with value-added nitrogen-containing compounds through co-pyrolysis of low-and high-protein bio-waste. The co-pyrolysis process resulted in higher bio-oil yield and increased proportion of fatty acids/esters compared to individual pyrolysis. Transesterification of the co-pyrolyzed bio-oil showed a significantly higher biodiesel proportion and total energy output than conventional bio-oil production. The presence of value-added nitrogen-containing compounds in the co-pyrolyzed bio-oil also added additional revenue potential.

Summary: This study investigated the use of waste aqueous phase from hydrothermal sludge treatment for cultivating the microalgae Chlorella sp. The results showed that the waste aqueous phase can serve as a suitable medium for Chlorella sp, with a nitrogen and phosphorus removal efficiency of over 90%. It was also found that the addition of CO2 during microalgal cultivation can enhance the growth of Chlorella sp and increase lipid content. Optimal cultivation conditions were determined as 5% CO2, BG-11/SAP = 1:1 mixed medium, and a cultivation period of 8 days. Furthermore, a comparison was made between the bio-oil and aqueous phase obtained from fast hydrothermal liquefaction and regular hydrothermal liquefaction.

Summary: Activated biochar prepared from phaeophyte Hizikia fusiformis was used as a catalyst for monophenols recovery during the pyrolysis of waste sawdust. The results showed that KOH as an activator had the highest environmental burdens and lower greenhouse gas emissions compared to other activated biochars. The activated biochar catalyst significantly promoted the yields of monophenols due to its porous structure and surface functional groups.

Summary: The effects of biochemical components and processing variables on the product yields and biofuel quality during fast hydrothermal liquefaction of CO2-tolerant microalgae were investigated. Results showed that the maximum bio-oil yield was obtained at specific conditions, and ethanol concentration had the highest impact on bio-oil yield. Furthermore, the increase of ethanol concentration improved the bio-oil quality by reducing carboxylic acids and nitrogen-containing compounds while enhancing the esters content. Fast hydrothermal liquefaction is a promising approach to produce high-quality biofuels from microalgae.

Summary: Biomass based activated carbon material was prepared by NaOH activation method using macroalgae as raw material to adsorb methylene blue. The activated adsorbent exhibited high specific surface area (1238.491 m(2) g(-1)) and mesoporous slit structure. The study investigated the effects of impregnation ratio, amount of adsorbent, pH, and contact time on the adsorption activity, and discussed the adsorption kinetics, molecular dynamics, and density functional theory. The SWAC achieved a maximum MB removal efficiency of 98.56% at 30°C and pH 5, attributed to its large specific surface area and presence of graphitic N sites for high electronegativity, facilitating stable adsorption of MB molecules through pi-pi stacking, cation-pi interaction, and electrostatic interaction.

Summary: The study aimed to analyze the levels of heavy metals in fish from the Yangtze River and their implications for human health. Six different fish species were collected and their muscle tissues were digested using standard protocols. The concentrations of lead, cadmium, zinc, aluminum, cobalt, manganese, chromium, and copper were analyzed. The results showed that zinc had the highest mean concentration in one of the fish species, followed by manganese, copper, lead, chromium, cadmium, and nickel. Health risk assessments indicated that children are particularly at risk for lead, cadmium, and cobalt when consuming these fish species.

Summary: This study investigated the control mechanism of free radicals on phenolic products selectivity by using guaiacol as a model chemical. The results showed that gaseous radicals or carbon-centered radicals could promote phenols formation through different mechanisms. Methyl radicals were mainly responsible for the selectivity of phenols in the gas-phase system, while in the heterogeneous system, adsorption of methyl radicals and phenolic radicals on carbon edge sites played a crucial role. The presence of carbon-centered radicals distributed at zigzag edges on the carbon surface was found to be essential for the rapid conversion of lignin to phenols.

Summary: This study presents a novel pretreatment method using hydrotropic p-toluenesulfonic acid (TsOH) mixed with pentanol for efficient fractionation of lignocellulosic biomass (LCB). The pretreatment resulted in the dissolution of majority of lignin and hemicellulose in the biphasic phase, while retaining most of the cellulose in the solid phase. The cellulose-rich fraction was further fermented to produce bioethanol, while the xylose-rich phase was converted into xylonic acid.

Summary: With the growth of the chemical industry, the demand for cheaper and more environmentally friendly alternatives to petrochemicals has increased. Oleochemicals and biodiesel are considered as green alternatives to petroleum derivatives. The enzymatic production of these compounds is more environmentally friendly and energy efficient compared to traditional chemical processes. However, the high cost of lipases has limited their large-scale utilization. This review discusses the factors affecting the economic feasibility of enzymatic processes and reports the recent advances in lipase-catalyzed production of these compounds in both lab and large-scale settings.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.
