Abstract Energy derived from fossil fuels contributes significantly to global climate change, accounting for more than 75% of greenhouse gas emissions and approximately 90% all carbon dioxide emissions. Alternative energy renewable sources must be utilized decarbonize the sector. However, adverse effects such as increasing temperatures, extreme winds, rising sea levels, decreased precipitation, may impact energies. Here we review energies with a focus on costs, energies, environment, economy, decarbonization in different countries. We solar, wind, biomass, hydropower, geothermal energy. observe that price solar photovoltaic has declined $0.417 2010 $0.048/kilowatt-hour 2021. Similarly, prices have by 68% onshore 60% offshore concentrated power, 14% biomass Wind hydropower production could decrease much 40% some regions due whereas appears least impacted source. Climate change can also modify productivity, growth, chemical composition, soil microbial communities. Hydroelectric power plants are most damaging environment; photovoltaics carefully installed reduce their impact. turbines minimal environmental impact; therefore, they should implemented extensively. Renewable electricity industry 2050, drastically reducing emissions, contributing mitigation. By establishing zero emission concept, future is promising, potential replace fuel-derived limit temperature rise 1.5 °C 2050.

Abstract The development and recycling of biomass production can partly solve issues energy, climate change, population growth, food feed shortages, environmental pollution. For instance, the use seaweeds as feedstocks reduce our reliance on fossil fuel resources, ensure synthesis cost-effective eco-friendly products biofuels, develop sustainable biorefinery processes. Nonetheless, in several biorefineries is still infancy stage compared to terrestrial plants-based lignocellulosic biomass. Therefore, here we review seaweed with focus production, economical benefits, feedstock for anaerobic digestion, biochar, bioplastics, crop health, food, livestock feed, pharmaceuticals cosmetics. Globally, could sequester between 61 268 megatonnes carbon per year, an average 173 megatonnes. Nearly 90% sequestered by exporting deep water, while remaining 10% buried coastal sediments. 500 gigatonnes replace nearly 40% current soy protein production. Seaweeds contain valuable bioactive molecules that be applied antimicrobial, antioxidant, antiviral, antifungal, anticancer, contraceptive, anti-inflammatory, anti-coagulants, other cosmetics skincare products.

Abstract Climate change issues are calling for advanced methods to produce materials and fuels in a carbon–neutral circular way. For instance, biomass pyrolysis has been intensely investigated during the last years. Here we review of algal lignocellulosic with focus on products mechanisms, oil upgrading, combining anaerobic digestion, economy, life cycle assessment. Products include oil, gas, biochar. Upgrading techniques comprise hot vapor filtration, solvent addition, emulsification, esterification transesterification, hydrotreatment, steam reforming, use supercritical fluids. We examined economic viability terms profitability, internal rate return, return investment, carbon removal service, product pricing, net present value. also reviewed 20 recent studies found that method highly influenced yield, ranging from 9.07 40.59% 10.1 41.25% biochar, 11.93 28.16% syngas. Feedstock type, pyrolytic temperature, heating rate, reaction retention time were main factors controlling distribution products. Pyrolysis mechanisms bond breaking, cracking, polymerization re-polymerization, fragmentation. Biochar residual forestry could sequester 2.74 tons dioxide equivalent per ton biochar when applied soil thus potential remove 0.2–2.75 gigatons atmospheric annually. The generation bio-oil process is estimated be economically feasible.

In circular economies, it is imperative to implement effective environmental management solutions address resource depletion. Over the past few years, there has been a growing recognition of potential agricultural crop waste in mitigating greenhouse gas (GHG) emissions and promoting global carbon neutrality. Despite lacking practical options, open-field burning residue contributes significantly air pollution. This challenge may be addressed by producing biochar through pyrolysis residues. A application agriculture can contribute reducing warming sequestration atmospheric from soil. As part life cycle assessment biochar, yield during its production are critical factors, which emphasize importance selecting method suitable for biochar. The objective this paper present comprehensive overview agronomic advantages associated with along detailed analysis (LCA). Furthermore, provides an how facilitate local energy sustainable within nexus agroecosystems, environment, energy.

Abstract The Climate Change Conference of Parties (COP) 21 in December 2015 established Nationally Determined Contributions toward reduction greenhouse gas emissions. In the years since COP21, it has become increasingly evident that carbon dioxide removal (CDR) technologies must be deployed immediately to stabilize concentration atmospheric gases and avoid major climate change impacts. Biochar is a carbon-rich material formed by high-temperature conversion biomass under reduced oxygen conditions, its production one few CDR methods can at scale large enough counteract effects within next decade. Here we provide generalized framework for quantifying potential contribution biochar make achieving national emissions goals, assuming use only sustainably supplied biomass, i.e., residues from existing agricultural, livestock, forestry wastewater treatment operations. Our results illustrate significant role play world-wide strategies, with 6.23 ± 0.24% total GHG 155 countries covered based on 2020 data over 100-year timeframe, more than 10% 28 countries. Concentrated regions high relative were identified South America, northwestern Africa eastern Europe. Graphical abstract

Abstract The rise of global waste and the decline fossil fuels are calling for recycling into energy materials. For example, rice straw, a by-product cultivation, can be converted biogas by-products with added value, e.g., biofertilizer, yet processing straw is limited by low content, high ash silica, nitrogen, moisture, high-quality variability. Here, we review focus on Chinese situations, conversion gas, digestate management, cogeneration, upgrading, bioeconomy, life cycle assessment. quality improved pretreatments, such as baling, ensiling, co-digestion other feedstocks. used to fertilize soils. average annual potential collectable lower heating value 15.35 megajoule/kilogram, over past ten years (2013–2022) could reach 2.41 × 10 9 megajoule.
