The synthetic dyes used in the textile industry pollute a large amount of water. Textile do not bind tightly to fabric and are discharged as effluent into aquatic environment. As result, continuous discharge wastewater from number industries without prior treatment has significant negative consequences on environment human health. contaminate habitats have potential be toxic organisms, which may enter food chain. This review will discuss effects water bodies, flora, degrade esthetic quality bodies by increasing biochemical chemical oxygen demand, impairing photosynthesis, inhibiting plant growth, entering chain, providing recalcitrance bioaccumulation, potentially promoting toxicity, mutagenicity, carcinogenicity. Therefore, dye-containing should effectively treated using eco-friendly technologies avoid environment, health, natural resources. compares most recent commonly remove dye wastewater, with focus advantages drawbacks these various approaches. is expected spark great interest among research community who wish combat widespread risk organic pollutants generated industries.

The massive consumption of a wide range plastic products has generated huge amount waste. There is need to provide awareness their uses and routine management as part our lifestyle. Nowadays, plastics are increasingly being used in daily life activities, including the packaging different food brewing companies, cosmetics, pharmaceutical, other production sectors pack end for efficient safer product's delivery community. Plastics produced through biochemical process polymerization or polycondensation. post-use waste many adverse impacts on environment if not processed managed proper way. This review aims discuss lifecycle according categories, polyvinyl chloride (PVC–U), polystyrene styrofoam (PS), polypropylene (PP), high-density polyethylene (HDPE), terephthalate (PETE), others. Herein, we have also discussed problems caused by inadequate processing possible solutions that can be provided ensure good atmosphere reduce causes climate changes, which challenging this planet.

Microalgae-based wastewater treatment: Mechanisms, challenges, recent advances, and future prospects

Environmental Science and Ecotechnology, Год журнала: 2022, Номер 13, С. 100205 - 100205

Опубликована: Сен. 8, 2022

The rapid expansion of both the global economy and human population has led to a shortage water resources suitable for direct consumption. As result, remediation will inexorably become primary focus on scale. Microalgae can be grown in various types wastewaters (WW). They have high potential remove contaminants from effluents industries urban areas. This review focuses recent advances WW through microalgae cultivation. Attention already been paid microalgae-based wastewater treatment (WWT) due its low energy requirements, strong ability thrive under diverse environmental conditions, transform nutrients into high-value compounds. It turned out that WWT is an economical sustainable solution. Moreover, different toxins are removed by biosorption, bioaccumulation, biodegradation processes. Examples agricultural runoffs textile pharmaceutical industrial effluents. mitigate carbon dioxide make use micronutrients present paper highlights application pollutants commonly mechanisms, simultaneous resource recovery, efficient co-culturing systems along with bottlenecks prospects.

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.

Bioplastic production in terms of life cycle assessment: A state-of-the-art review

Environmental Science and Ecotechnology, Год журнала: 2023, Номер 15, С. 100254 - 100254

Опубликована: Фев. 20, 2023

The current transition to sustainability and the circular economy can be viewed as a socio-technical response environmental impacts need enhance overall performance of linear production consumption paradigm. concept biowaste refineries feasible alternative petroleum has gained popularity. Biowaste become an important raw material source for developing bioproducts biofuels. Therefore, effective management systems biofuels are crucial employed pillars economy. Bioplastics, typically plastics manufactured from bio-based polymers, stand contribute more sustainable commercial plastic life cycles part in which virgin polymers made renewable or recycled materials. Various frameworks strategies utilized model illustrate additional patterns fossil fuel bioplastic feedstock prices various governments' long-term policies. This review paper highlights harmful fossil-based on environment human health, well mass eco-friendly alternatives such biodegradable bioplastics. Utilizing new types bioplastics derived resources (e.g., biowastes, agricultural wastes, microalgae) choosing appropriate end-of-life option anaerobic digestion) may right direction ensure production. Clear regulation financial incentives still required scale niche large-scale market applications with truly impact.

Degradation-fragmentation of marine plastic waste and their environmental implications: A critical review

Arabian Journal of Chemistry, Год журнала: 2022, Номер 15(11), С. 104262 - 104262

Опубликована: Сен. 18, 2022

This review critically evaluates the plastic accumulation challenges and their environmental (primarily) human (secondarily) impacts. It also emphasizes on degradation fragmentation phenomena under marine conditions. In addition, it takes into account leachability of various chemical substances (additives) embedded in products to improve polymeric properties extend life. Regardless effectiveness enhancing function products, these additives can potentially contaminate air, soil, food, water. Several findings have shown that, regardless types sizes, plastics be degraded and/or fragmented Therefore, estimation rates via a reliable developed model is required better understand status. The main parameter, which responsible for initiating plastics, sunlight/UV radiation. Yet, UV- radiation alone not enough fragment some polymer conditions, additional factors are needed such as mechanical abrasion. should mentioned that most current studies centered primary stages degradation. Thus, further identify fate effects.
