Environmental Chemistry Letters, Год журнала: 2022, Номер 21(2), С. 741 - 764

Опубликована: Окт. 28, 2022

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.

Опубликована: Апрель 4, 2023

Abstract Microplastic pollution is becoming a major issue for human health due to the recent discovery of microplastics in most ecosystems. Here, we review sources, formation, occurrence, toxicity and remediation methods microplastics. We distinguish ocean-based land-based sources Microplastics have been found biological samples such as faeces, sputum, saliva, blood placenta. Cancer, intestinal, pulmonary, cardiovascular, infectious inflammatory diseases are induced or mediated by exposure during pregnancy maternal period also discussed. Remediation include coagulation, membrane bioreactors, sand filtration, adsorption, photocatalytic degradation, electrocoagulation magnetic separation. Control strategies comprise reducing plastic usage, behavioural change, using biodegradable plastics. Global production has risen dramatically over past 70 years reach 359 million tonnes. China world's top producer, contributing 17.5% global production, while Turkey generates waste Mediterranean region, at 144 tonnes per day. 75% marine waste, with responsible 80–90% pollution, account only 10–20%. induce toxic effects on humans animals, cytotoxicity, immune response, oxidative stress, barrier attributes, genotoxicity, even minimal dosages 10 μg/mL.

Artificial intelligence for waste management in smart cities: a review

Environmental Chemistry Letters, Год журнала: 2023, Номер 21(4), С. 1959 - 1989

Опубликована: Май 9, 2023

Abstract The rising amount of waste generated worldwide is inducing issues pollution, management, and recycling, calling for new strategies to improve the ecosystem, such as use artificial intelligence. Here, we review application intelligence in waste-to-energy, smart bins, waste-sorting robots, generation models, monitoring tracking, plastic pyrolysis, distinguishing fossil modern materials, logistics, disposal, illegal dumping, resource recovery, cities, process efficiency, cost savings, improving public health. Using logistics can reduce transportation distance by up 36.8%, savings 13.35%, time 28.22%. Artificial allows identifying sorting with an accuracy ranging from 72.8 99.95%. combined chemical analysis improves carbon emission estimation, energy conversion. We also explain how efficiency be increased costs reduced management systems cities.

Recycling municipal, agricultural and industrial waste into energy, fertilizers, food and construction materials, and economic feasibility: a review

Environmental Chemistry Letters, Год журнала: 2023, Номер 21(2), С. 765 - 801

Опубликована: Янв. 7, 2023

Abstract The global amount of solid waste has dramatically increased as a result rapid population growth, accelerated urbanization, agricultural demand, and industrial development. world's is expected to reach 8.5 billion by 2030, while production will 2.59 tons. This deteriorate the already strained environment climate situation. Consequently, there an urgent need for methods recycle waste. Here, we review recent technologies treat waste, assess economic feasibility transforming into energy. We focus on municipal, agricultural, found that methane captured from landfilled-municipal in Delhi could supply 8–18 million houses with electricity generate 7140 gigawatt-hour, prospected potential 31,346 77,748 gigawatt-hour 2030 2060, respectively. Valorization food anaerobic digestion systems replace 61.46% natural gas 38.54% coal use United Kingdom, reduce land 1.8 hectares if provided animal feeds. also estimated levelized cost landfill waste-to-energy $0.04/kilowatt-hour $0.07/kilowatt-hour, payback time 0.73–1.86 years 1.17–2.37 years, Nonetheless, current treatment are still inefficient, particular treating containing over 60% water.
