Abstract The world is experiencing an energy crisis and environmental issues due to the depletion of fossil fuels continuous increase in carbon dioxide concentrations. Microalgal biofuels are produced using sunlight, water, simple salt minerals. Their high growth rate, photosynthesis, sequestration capacity make them one most important biorefinery platforms. Furthermore, microalgae's ability alter their metabolism response stresses produce relatively levels high-value compounds makes a promising alternative fuels. As result, microalgae can significantly contribute long-term solutions critical global such as climate change. benefits algal biofuel have been demonstrated by significant reductions dioxide, nitrogen oxide, sulfur oxide emissions. Microalgae-derived biomass has potential generate wide range commercially compounds, novel materials, feedstock for variety industries, including cosmetics, food, feed. This review evaluates microalgal bioenergy carriers, biodiesel from stored lipids, alcohols reserved carbohydrate fermentation, hydrogen, syngas, methane, biochar bio-oils via anaerobic digestion, pyrolysis, gasification. use routes atmospheric removal approach being evaluated. cost production primarily determined culturing (77%), harvesting (12%), lipid extraction (7.9%). choice species cultivation mode (autotrophic, heterotrophic, mixotrophic) factors controlling production, well fuel properties. simultaneous agricultural, municipal, or industrial wastewater low-cost option that could reduce economic costs while also providing valuable remediation service. Microalgae proposed viable candidate capture atmosphere point source. sequester 1.3 kg 1 biomass. Using potent strains efficient design bioreactors thus challenge. theoretically up 9% light convert 513 tons into 280 dry per hectare year open closed cultures. integrated bio-refinery recover high-value-added products waste create processing bioenergy. To system, should be coupled with thermochemical technologies, pyrolysis.

Abstract The construction industry is a major user of non-renewable energy and contributor to emission greenhouse gases, thus requiring achieve net-zero carbon emissions by 2050. Indeed, activities account for 36% global consumption 39% dioxide emissions. Reducing requires adapted government policies, analysis calculation models, sustainable materials. Here, we review green with focus on history, emissions, life cycle assessment, materials such as biochar, bioplastic, agricultural waste, animal wool, fly ash self-healing concrete. Analysis over the building shows that phase accounts 20–50% total average ratio annual operation 0.62. We present national policy frameworks technology roadmaps from United States America, Japan, China, European Union, highlighting plans neutrality in sector.

In this report, the utilization of mixed methanol-ethanol system for production biodiesel from waste cooking oil (WCO) using enhanced eggshell-derived calcium oxide (CaO) nano-catalyst was investigated. CaO produced by calcination eggshell powder at 900 °C and followed hydration-dehydration treatment to improve its catalytic activity. The particle size, morphology, elemental composition a catalyst were characterized XRD, SEM, EDX techniques, respectively. After shape changed rod-like honeycomb-like porous microstructure. Likewise, average size reduced 21.30 13.53 nm, as result, surface area increases. main factors affecting yield investigated, accordingly, an optimal 94% obtained 1:12 methanol molar ratio, 2.5 wt% loading, 60 °C, 120-min reaction time. A 88% 6:6 equimolar ratio ethanol, even increased 91% increasing loading 3.5 wt%. Moreover, slightly share in mixture, 8:4 maximum could reach 92%. Therefore, we suggest mixture reactant conversion WCO into biodiesel. It is very promising approach development low-cost environmentally friendly technology. Properties also found good agreement with American (ASTM D6571) fuel standards.

Abstract Climate change and the unsustainability of fossil fuels are calling for cleaner energies such as methanol a fuel. Methanol is one simplest molecules energy storage utilized to generate wide range products. Since can be produced from biomass, numerous countries could produce utilize biomethanol. Here, we review production processes, techno-economy, environmental viability. Lignocellulosic biomass with high cellulose hemicellulose content highly suitable gasification-based biomethanol production. Compared fuels, combustion reduces nitrogen oxide emissions by up 80%, carbon dioxide 95%, eliminates sulphur emission. The cost yield largely depend on feedstock characteristics, initial investment, plant location. use complementary fuel diesel, natural gas, dimethyl ether beneficial in terms economy, thermal efficiency, reduction greenhouse gas emissions.

Abstract In the context of climate change, there is an urgent need for rapid and efficient methods to capture sequester carbon from atmosphere. For instance, production, use storage biochar are highly negative, resulting in estimated sequestration 0.3–2 Gt CO 2 year −1 by 2050. Yet, production requires more knowledge on feedstocks, thermochemical conversion end applications. Herein, we review design development systems, investigate removal industry. Carbon efforts currently promoted via voluntary market. The major commercialized technologies offering atmospheric forestation, direct air utilization storage, soil sequestration, wooden building elements biochar, with corresponding fees ranging 10 895 GBP (British pounds) per ton . Biochar range 52 131 , which indicates that a realistic strategy can be deployed at large scale. services offered through robust marketplaces require extensive certification, verification monitoring, adds element credibility authenticity. eligibility dependent type feedstock utilized processing conditions employed. Process optimization imperative produce product meets application-specific requirements, environmental regulations achieve ultimate stability purposes.
