Realizing integrated biorefineries producing multiple fuels, chemicals and materials from sustainable biomass feedstocks holds promise for transitioning industries onto low-carbon trajectories. However, widespread commercial implementation remains elusive despite two decades of technological advancements. This review synthesizes current literature to provide a comprehensive analysis key multi-dimensional barriers inhibiting the scale-up biorefineries. The discusses technical challenges around conversion processes. Economic viability concerns such as high capital costs lack market competitiveness are also assessed. evaluates regulatory policy complexities that poses risks uncertainties in scaling up Socio-political acceptance hurdles including community engagement public perception reviewed. interconnected nature these is emphasized strategies recommended enable full potential realization, covering areas enhanced stakeholder collaboration, advanced process intensification, supportive frameworks, innovative financing models strategic marketing initiatives. International pilots cross-sectoral knowledge exchange highlighted priority enablers. In conclusion, this insights extensive demonstration efforts identify priorities pathways accelerating global transition towards biorefinery implementation. It aims inform decision-making collaborative actions amongst stakeholders research, industry domains.

Palm oil mill effluent (POME) has a high concentration of organic matter and total suspended solids. However, improper disposal refining wastes containing oils, fats, sludge can cause environmental damage harm human health due to their toxic, carcinogenic, polluting effects. This research was carried out solve the harmful effects caused by release POME environment. The goal this study isolate naturally occurring bacterium that could degrade use it as single carbon source. Bacteria were isolated from POME-contaminated medium using an enrichment technique. Judging 16S rRNA partial gene sequencing, morphological, biochemical, molecular identification methods, bacteria identified novel Bacillus sp. substrate concentration, inoculum size, pH, temperature, incubation time on bacterial growth investigated "one factor at time" (OFAT) approach. optimal conditions for bacterium's found be pH 7.5, 35 °C, 20 % v/v 6 96 hours incubation. is capable reducing 84 COD 91 BOD sample. degradation potential suggests used good option bioremediation POME-polluted areas.

Phenol and its derivatives are pollutants of great environmental concern due to their acute toxicity even in minute amounts, both aquatic life people. Many regulatory bodies have tagged them as priority pollutants. levels exceeding the acceptable limit our environment is no longer a new issue there rise contamination phenol rapid industrialization. Thus, increased interest this pollutant's investigation related significance urgency removal. Several methods currently used for removal from aqueous solutions. Each method associated with advantages disadvantages but by far adsorption using adsorbent most widely method. The sorption phenolic compounds very complex process, many factors influence it. This paper presents summary parameters influencing capacity compound such capacity, efficiency, effects pH, contact time, effect sorbent dosage, concentration temperature various adsorbents been reviewed.

Chlorpyrifos, being a frequently used organophosphate pesticide poses significant threat to human health due its prolonged presence in soil, plants, and water, this has raised concern. Consequently, researchers have shifted their attention towards finding methods mitigate toxicity or eliminate it from the environment. This highlighted importance of bioremediation. study was aimed at analyzing characterizing metabolites chlorpyrifos degradation by Bacillus sp. strain UPMB10 isolated polluted environment using Gas Chromatography-Mass Spectrometry. The bacteria were successfully utilizing enrichment technique mineral salt media, followed screening obtain best isolate. Identification isolate done morphological, biochemical, molecular levels, with focus on 16S rRNA gene. Phylogenetic analysis revealed close relationship between bacterium UPMB10. Optimization (One Factor A Time) determine growth conditions optimal obtained include, incubation time 48 hours, substrate concentration 4 g/L, pH 7.0, temperature 37 °C, an inoculum size 2 % (v/v), these quantitative data valuable insights into factors affecting efficient pesticide. Spectrometry demonstrated that achieved remarkable efficiency 99 after hours incubation. Notably, Mesitylene Dimethylmalonic acid as some degradation. result provides insight transformation products generated during process. exhibits capacity for degradation, making promising candidate bioremediation insecticides acaricides.

Fungal processes for the treatment of dye contaminated wastewater have advantage being cost-effective, environmentally friendly, and producing less sludge. This research was therefore aimed at isolating characterizing fungus capable decolourizing utilizing azo (dimethyl yellow) as a sole carbon source using one-factor-at-a-time. Pour plating method used to isolate on mineral salt media (MSM) following serial dilution. The then morphologically molecularly identified Aspergillus quadrilineatus strain BUK_BCH_BTE1 with accession number OK178927 based ITS1 ITS2 rRNA gene sequence molecular phylogenetic analysis. Characterization conducted by studying effect temperature, incubation time, substrate concentration, pH, inoculum size heavy metals. decolourization growth dimethyl yellow isolated optimal concentration 200 μɡ/mL, temperature 30 °C, 100–200 μL size, pH 5.0, 72-hour time. found tolerate up 4 ppm Hg, Cu Zn, maximum inhibition shown Cr Ar. LC/MS analyses intermediate compounds produced during suggested that in fungal biodegradation detected formation yellow, 2,6-dichloro-p-benzoquinone, 1,2,3,5-tetrafluoro-4-nitrobenzene, 3,4-dinitrobenzoic acid metabolites. finding from this study is suitable candidate bioremediation coloured effluents particularly containing these compounds.

The valorization of byproducts such as defatted meal (DM) is essential for the implementation a biorefinery structure and can be achieved through application emerging technologies, pressurized liquid extraction. This work aimed to apply extraction obtain products derived from DM crambe (Crambe abyssinica Hochst) seeds. experiments investigated effect ethanol percentage in hydroalcoholic solvent (25%, 50% 75%, v/v) on mass extract yield (MEY) composition obtained: phytochemical (PE) processed flour (PF). PE obtained using 25% ethanolic had highest MEY (23.48 wt%) phenolic compounds, composed caffeic, gallic ferulic acids, which conferred activity against fungus C. albicans. solvents tested did not influence content soluble proteins. with 75% promoted levels glucosinolates (258.94 μmol/g) tannins (8.80 mg/g) PE, reducing 96% 98% these contents PF produced. contained compounds (~23 mg/100 g), dietary fibers (54.25 g/100 g) proteins (26.39 wt%), mainly glutelin fraction. also presented adequate functional properties, water solubility absorption, suggest potential use pet food formulations.
