Herein, we reported an efficient and novel metal–organic framework (MOF) that was designed fabricated via hydrothermal reaction of chromium(III) nitrate nonahydrate salt with EDTA as organic ligand. The prepared MOF investigated by PXRD, BET, SEM, EDS, FT-IR, X-ray mapping techniques. N2 adsorption–desorption isotherms indicated excellent BET surface area for Cr-EDTA-MOF, which is 234.55 m2/g. Cr-EDTA-MOF exhibits potential performance the esterification oleic palmitic acids under gentle conditions. Furthermore, this nanostructure material afforded several benefits, including product yields, stability, easy methodology, workup, greener situations. heterogeneous nanocatalyst (Cr-EDTA-MOF) could be easily recovered from mixture centrifugation reused four consecutive runs a minimum loss catalytic activity.

It has been repeatedly and independently proved that biochar applications brings a wide range of environmental advantages. For these benefits to have any tangible impact on global scale, needs be applied in substantial quantities. However, the commercial applicability most research date is limited by demanding requirements for used (pricy feedstocks or activated ways). Nevertheless, such production alternatives increase costs thus undermine financial sustainability many applications. In contrast, from digestate via waste heat (from methane combustion at biogas plants) several synergies make it possible obtain low constant quality throughout year. Techno-economic considerations above-reviewed literature indicates first time this competitive advantage can mass scale eutrophication prevention. Based synthesis reviewed literature, review accompanied (1) proposal activation subsequent use wastewater treatment plants (2) estimate, which profitability new application.

Abstract Environmental pollution is a big challenge that has been faced by humans in contemporary life. In this context, fossil fuel, cement production, and plastic waste pose direct threat to the environment biodiversity. One of prominent solutions use renewable sources, different organisms valorize wastes into green energy bioplastics such as polylactic acid. Chlorella vulgaris , microalgae, promising candidate resolve these issues due its ease cultivation, fast growth, carbon dioxide uptake, oxygen production during growth on wastewater along with biofuels, other productions. Thus, article, we focused potential be used treatment, biohydrogen, biocement, biopolymer, food additives, preservation, biodiesel which seen most for industrial scale, related biorefineries recent applications brief review acid market size realize technical/nontechnical reasons behind cost obstacles hinder mentioned applications. We believe our findings are important those who interested scientific/financial research about microalgae.

Waste oil treatment and the burning of fossil fuels are causing environmental problems, thus using waste oils as pyrolysis feedstock to produce high-grade biofuels is receiving a lot attention. Higher hydrogen volatile matter contents make them an optimal raw material for biofuel production. Conversely, attaining satisfactory effects employing traditional disposal methods such gasification, solvent extraction, transesterification, membrane technology, hydro-treating strenuous. Clean secure technology can help overcome present dilemma. Biofuels obtained by replace fuel it has been proven have high yield higher heating value (HHV); however, they contain acid value. Nevertheless, treating with metal, zeolites, other bi-functional catalysts helps decrease Energy time be effectively saved improved bio-oil quality co-pyrolysis plastic waste. A comprehensive assessment production via conventional progressive investigated. The current evaluation defines technical economical routine from numerous biomass through pyrolysis. Analyzing cost one crucial components in determining market affinity different alternative biofuels. Bio-oil made energy integration approach smoothly. Life cycle (LCA) co-feeds was also discussed in-depth. conclusions gained following study might influence research on industry targeted at commercializing product.

The adverse effects of microplastics on microalgae species have been extensively studied, but their impact the bait entering food chain has not well understood. This study investigated cytological and physiological response Isochrysis galbana to polyethylene (PE-MPs, 10 μm) nanoplastics (PE-NPs, 50 nm). results showed that PE-MPs had no significant I. galbana, while PsE-NPs obviously inhibited cell growth, reduced chlorophyll content, caused a decline in carotenoids soluble protein. These changes quality could negatively affect its use as aquaculture feed. To understand molecular mechanism PE-NPs, transcriptome sequencing was performed. result revealed TCA cycle, purine metabolism, some key amino acid syntheses were down-regulated by Calvin cycle fatty metabolism up-regulated tolerate PE-NP pressure. Microbial analysis bacterial community structure associated with significantly altered at level PE-NPs. In conclusion, this provides new insights into stress microplastic pollution based analysis. findings highlight need mitigate release environment prevent harmful aquatic ecosystems will be helpful understanding microalgae.
