Plastic usage is increasing the number of pollutants in environment. particles and other plastic-based are found our environment food chain, posing a threat to human health. From this perspective, biodegradable plastics material focuses on creating more sustainable greener world with smaller environmental imprint. This assessment should consider entire life cycle objectives priorities for producing wide range plastics. Biodegradable can also have properties similar traditional while delivering additional benefits due their minimised impact terms carbon dioxide, as long appropriate waste management includes such composting, contained. The demand cost-effective, eco-friendly materials increases reduce pollution issues. study seeks comprehensively understand production applications research, product prospects, sustainability, sourcing ecological Academic industry interest sustainability has exploded recent years. Researchers used triple bottom line analyse (economic profit, social responsibility, protection). research discusses variables that influence adoption framework improving plastics' long-term viability. provides thorough yet simple theoretical design findings future endeavours provide new avenue further contribution area.

Microplastic sources, formation, toxicity and remediation: a review

Environmental Chemistry Letters, Год журнала: 2023, Номер 21(4), С. 2129 - 2169

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. Ingestion animals results alterations gastrointestinal tract physiology, system depression, differential gene expression, growth inhibition. Furthermore, bioaccumulation tissues aquatic organisms can adverse ecosystem, potential transmission birds. Changing individual behaviours governmental actions, implementing bans, taxes, pricing carrier bags, significantly reduced consumption 8–85% various countries worldwide. The microplastic minimisation approach follows an upside-down pyramid, starting prevention, followed reducing, reusing, recycling, recovering, ending disposal least preferable option.

Biodegradable Plastics: Standards, Policies, and Impacts

ChemSusChem, Год журнала: 2020, Номер 14(1), С. 56 - 72

Опубликована: Окт. 28, 2020

Plastics are ubiquitous in our society. They phones, clothes, bottles, and cars. Yet having improved lives considerably, they now threaten environment health. The associated carbon emissions persistency of plastics challenge the fragile balance many ecosystems. One solution is using biodegradable plastics. Ideally, such easily assimilated by microorganisms disappear from environment. This can help reduce problems climate change, microplastics, littering. However, still only a tiny portion global market require further efforts research commercialization. Here, critical overview state art given. Using material flow analysis, challenges plastic highlighted, with it large potential environmental socio-economic impact plastics, government policies, standards certifications, physico-chemical properties, analytical techniques covered. Review concludes personal outlook on future bioplastics, based own experience their development

Recent Progress in the Chemical Upcycling of Plastic Wastes

ChemSusChem, Год журнала: 2021, Номер 14(19), С. 4137 - 4151

Опубликована: Май 18, 2021

The massive generation of plastic wastes without satisfactory treatment has induced severe environmental problems and gained increasing attentions. In this Minireview, recent progresses in the chemical upcycling by using various methods (mainly past three to five years) is summarized. points out a "plastic-based refinery" concept, which use as platform feedstocks produce highly valuable monomeric or oligomeric compounds, putting back into circular economy. different upcycle wastes, including hydrogenolysis, photocatalysis, pyrolysis, solvolysis, others, are introduced each section valorize diverse value-added chemicals, materials, fuels. addition, other emerging technologies well new thermosets covered.

A Review of Biodegradable Plastics: Chemistry, Applications, Properties, and Future Research Needs

Chemical Reviews, Год журнала: 2023, Номер 123(16), С. 9915 - 9939

Опубликована: Июль 20, 2023

Environmental concerns over waste plastics' effect on the environment are leading to creation of biodegradable plastics. Biodegradable plastics may serve as a promising approach manage issue environmental accumulation plastic in ocean and soil. type polymers that can be degraded by microorganisms into small molecules (e.g., H2O, CO2, CH4). However, there misconceptions surrounding For example, term "biodegradable" product labeling misconstrued public imply will degrade under any conditions. Such misleading information leads consumer encouragement excessive consumption certain goods increased littering products labeled "biodegradable". This review not only provides comprehensive overview state-of-the-art but also clarifies definitions various terms associated with plastics, including oxo-degradable enzyme-mediated biodegradation agents. Analytical techniques standard test methods evaluate biodegradability polymeric materials alignment international standards summarized. The summarizes properties industrial applications previously developed then discusses how biomass-derived monomers create new types utilizing their unique chemical from oxygen-containing functional groups. terminology methodologies covered paper provide perspective directions for design possess advanced performance practical benefits.

Turning Food Protein Waste into Sustainable Technologies

Chemical Reviews, Год журнала: 2022, Номер 123(5), С. 2112 - 2154

Опубликована: Июнь 30, 2022

For each kilogram of food protein wasted, between 15 and 750 kg CO2 end up in the atmosphere. With this alarming carbon footprint, waste not only contributes to climate change but also significantly impacts other environmental boundaries, such as nitrogen phosphorus cycles, global freshwater use, land composition, chemical pollution, biodiversity loss. This contrasts sharply with both high nutritional value proteins, well their unique physical versatility, which enable use new materials innovative technologies. In review, we discuss how can be efficiently valorized by reintroduction into chain supply a template for development sustainable technologies allowing it exit food-value chain, thus alleviating some most urgent challenges. We showcase three immediate significance impact: biodegradable plastics, water purification, renewable energy. discuss, carefully reviewing current state art, proteins extracted from key players facilitate these furthermore support analysis extant literature original life cycle assessment (LCA) examples run ad hoc on plant animal context considered, against realistic benchmarks, quantitatively demonstrate efficacy potential. finally conclude review an outlook comprehensive management is anticipated transform its footprint positive negative and, more generally, have favorable impact several important planetary boundaries.
