Summary: The study explores the utilization of different extraction techniques to convert microalgal consortium biomass into value-added products (VAPs). Supercritical CO2 extraction (SFE) was found to yield higher lipid content with increased polyunsaturated fatty acids (PUFAs). Subcritical-hydrothermal liquefaction (HTL) produced biocrude with aldehyde/ketone, aromatics, and alkanes/alkenes/alkynes, targeting various industries. The sequential SFE-HTL process showed improved biocrude quality and extraction of PUFAs.

Summary: This study assessed the double effect of supercritical carbon dioxide (sc-CO2) in a biorefinery concept applied to brewer's spent grain (BSG). The results showed that high pressures and temperatures resulted in higher content of phenolic and flavonoid compounds, as well as higher antioxidant capacity. Additionally, the enzymatic hydrolysis yield of cellulase in the sc-CO2 treated BSG was improved compared to the non-treated BSG, which could be attributed to the removal of the lipid fraction and morphological changes.

Summary: This study investigates the effects of water content, operating pressure and temperature on supercritical CO2 extraction of lipids from Chlorella vulgaris microalgae. The highest extraction yield was obtained with freeze-dried microalgae at 40℃ and 200 bar. However, extracts obtained at 40℃ and 250 bar had the highest fatty acid content, while those obtained at 60℃ and 250 bar had the highest cetane number and oxidative stability. Water in the initial biomass had a negative impact on total extraction yield, but promoted the extraction of fatty acids, particularly monounsaturated ones.

Summary: Effluents from SCWG process mixed with Bristol Medium at 600 degrees C showed improvement in growth rate for cultivating Chlorella vulgaris. The low non-purgeable organic carbon content indicated that inhibiting materials were decomposed at the high temperature of 600 degrees C. Furthermore, phosphorus accumulation in C. vulgaris was significantly higher in the SCWG mixed medium, suggesting the potential for nutrient recycling processes using a combination of C. vulgaris and SCWG effluents.

Summary: This study investigated the use of whey beverages enriched with FOS and XOS as carriers for fennel extract obtained by supercritical CO2 extraction. The research found that thermosonication processing effectively protected the bioactive fennel compounds, and the addition of prebiotic dietary fibers reduced the droplet size in the beverages. However, thermosonication treatments reduced the kinetic stability of the beverages. Overall, the colloidal dairy systems preserved the antioxidant capacity of the fennel seed extract, regardless of thermosonication treatment intensity.

Summary: Ethanol and starch are the main products generated from corn processing, while byproducts such as stover, distillers' solubles, gluten meal, and DDGS have valuable compounds for industry. Supercritical technology has been used to valorize these byproducts, yielding biodiesel, biogas, microcapsules, and nutrient extracts. Supercritical technology also offers pretreatment of solid byproducts for hydrolysis and the ability to transform these byproducts into products like structured lipids and fermentable sugars. Process intensification through integration with supercritical fluid equipment could reduce costs and generate novel products.

Summary: Fuels from bio-based resources have the potential to replace fossil fuels in the transportation sector, reducing emissions at reasonable costs. However, shifting to renewables may cause imbalances between electricity supply and demand. This study explores the use of integrated biorefineries to balance electricity and produce fuels from biomass. By integrating a pulp mill with thermochemical conversion processes, emissions can be reduced by up to 90% compared to non-integrated systems. Optimization shows that emission reduction comes with added expenses, but a 50% reduction can provide economic benefits. The benefits of integration at the European level depend on the region's energy portfolio.

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.
