The increasing global industrialization and over-exploitation of fossil fuels has induced the release greenhouse gases, leading to an increase in temperature causing environmental issues. There is therefore urgent necessity reach net-zero carbon emissions. Only 4.5% countries have achieved neutrality, most are still planning do so by 2050-2070. Moreover, synergies between different hampered adaptation mitigation policies, as well their co-benefits. Here, we present a strategy neutral economy examining outcome goals 26th summit United Nations Climate Change Conference Parties (COP 26). Methods been designed for mapping emissions, such input-output models, spatial systems, geographic information system maps, light detection ranging techniques, logarithmic mean divisia. We decarbonization technologies initiatives, negative emissions technologies, discuss trading tax. propose plans neutrality shifting away from toward renewable energy, development low-carbon agriculture, changing dietary habits value food agricultural waste. Developing resilient buildings cities, introducing decentralized energy electrification transportation sector also necessary. review life cycle analysis systems.

Abstract Dihydrogen (H 2 ), commonly named ‘hydrogen’, is increasingly recognised as a clean and reliable energy vector for decarbonisation defossilisation by various sectors. The global hydrogen demand projected to increase from 70 million tonnes in 2019 120 2024. Hydrogen development should also meet the seventh goal of ‘affordable energy’ United Nations. Here we review production life cycle analysis, geological storage utilisation. produced water electrolysis, steam methane reforming, pyrolysis coal gasification. We compare environmental impact routes analysis. used power systems, transportation, hydrocarbon ammonia production, metallugical industries. Overall, combining electrolysis-generated with underground porous media such reservoirs salt caverns well suited shifting excess off-peak dispatchable on-peak demand.

Abstract The global energy demand is projected to rise by almost 28% 2040 compared current levels. Biomass a promising source for producing either solid or liquid fuels. Biofuels are alternatives fossil fuels reduce anthropogenic greenhouse gas emissions. Nonetheless, policy decisions biofuels should be based on evidence that produced in sustainable manner. To this end, life cycle assessment (LCA) provides information environmental impacts associated with biofuel production chains. Here, we review advances biomass conversion and their impact assessment. Processes gasification, combustion, pyrolysis, enzymatic hydrolysis routes fermentation. Thermochemical processes classified into low temperature, below 300 °C, high higher than i.e. combustion pyrolysis. Pyrolysis because it operates at relatively lower temperature of up 500 which 800–1300 °C. We focus 1) the drawbacks advantages thermochemical biochemical various possibility integrating these better process efficiency; 2) methodological approaches key findings from 40 LCA studies pathways published 2019 2021; 3) bibliometric trends knowledge gaps using routes. integration hydrothermal circular economy.

Abstract Global industrialization and excessive dependence on nonrenewable energy sources have led to an increase in solid waste climate change, calling for strategies implement a circular economy all sectors reduce carbon emissions by 45% 2030, achieve neutrality 2050. Here we review with focus management, energy, air water quality, land use, industry, food production, life cycle assessment, cost-effective routes. We observed that increasing the use of bio-based materials is challenge terms cover. Carbon removal technologies are actually prohibitively expensive, ranging from 100 1200 dollars per ton dioxide. Politically, only few companies worldwide set change goals. While can be implemented various such as waste, buildings, transportation, assessment required optimize new systems. Overall, provide theoretical foundation sustainable industrial, agricultural, commercial future constructing routes economy.

Aiming at meeting the global goals established for carbon dioxide (CO2) reduction, capture and storage (CCS) plays a key role. In this framework, adsorption-based CO2 post-combustion is considered one of most promising approaches because it can provide remarkable energy savings with respect to standard amine-based absorption capture. To date, research effort has been devoted development novel cutting-edge adsorbent materials primary purpose enhancing adsorption capacity lifetime while reducing heat adsorption, thus lessening energetic requirement sorbent regeneration. Anyway, other factors, beyond sorbents, greatly affect competitiveness based on route, namely, gas–solid contacting system, impacting utilization efficiency, regeneration strategies, determining costs. This review describes state-of-the-art recent progresses particular, first section performances different classes solid sorbents basis important evaluation parameters (equilibrium capacity, multi-cyclic stability, etc.). second section, two main systems, i.e., fixed beds fluidized beds, have reviewed, pointing out their strengths limitations. Finally, third provides modes (temperature, pressure, or hybrid swings), focus possible strategies available limit penalty.

Abstract In the context of climate change and circular economy, biochar has recently found many applications in various sectors as a versatile recycled material. Here, we review application biochar-based for carbon sink, covering agronomy, animal farming, anaerobic digestion, composting, environmental remediation, construction, energy storage. The ultimate storage reservoirs are soils, civil infrastructure, landfills. Biochar-based fertilisers, which combine traditional fertilisers with nutrient carrier, promising agronomy. use feed additive animals shows benefits terms growth, gut microbiota, reduced enteric methane production, egg yield, endo-toxicant mitigation. Biochar enhances digestion operations, primarily biogas generation upgrading, performance sustainability, mitigation inhibitory impurities. composts, controls release greenhouse gases microbial activity. Co-composted improves soil properties crop productivity.

Biomass waste-derived porous carbons (BWDPCs) are a class of complex materials that widely used in sustainable waste management and carbon capture. However, their diverse textural properties, the presence various functional groups, varied temperatures pressures to which they subjected during CO2 adsorption make it challenging understand underlying mechanism adsorption. Here, we compiled data set including 527 points collected from peer-reviewed publications applied machine learning systematically map as function compositional properties BWDPCs parameters. Various tree-based models were devised, where gradient boosting decision trees (GBDTs) had best predictive performance with R2 0.98 0.84 on training test data, respectively. Further, classified into regular (RPCs) heteroatom-doped (HDPCs), again GBDT model 0.99 0.86 0.79 for RPCs HDPCs, Feature importance revealed significance parameters, order precedence BWDPC-based adsorption, effectively guiding synthesis applications.
