Plastic waste and its management strategies for environmental sustainability

Case Studies in Chemical and Environmental Engineering, Journal Year: 2021, Volume and Issue: 4, P. 100142 - 100142

Published: Sept. 27, 2021

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.

Environmental challenges induced by extensive use of face masks during COVID-19: A review and potential solutions

Environmental Challenges, Journal Year: 2021, Volume and Issue: 3, P. 100039 - 100039

Published: Feb. 10, 2021

The ongoing COVID-19 disease significantly affects not only human health, it also the wealth of country' economy and everyday routine life. To control spread virus, face mask is used as primary personal protective equipment (PPE). Thus, production usage masks increase pandemic still escalating. Further, most these contain plastics or other derivatives plastics. Therefore, this extensive generates million tons plastic wastes to environments in a short span time. This study aims investigate environmental impact induced by sustainable solution reduce waste. An online survey was carried out identify types number per week an individual from 1033 people. Based on available literature, quantifies amount waste generated masks. However, limited with certain ages, country durations (July-August 2020). prediction generation, provide fundamental knowledge about wastes. Results revealed that there huge remained land marine environment form waste, which will contribute micro-plastic pollution. paper highlights approach integrating use natural plant fiber woven technology upcycling producing construction materials discussed.

People discover various materials from time to that break the boundaries of traditional materials. Plastic is a revolutionized material, and referred as "a material with 1,000 uses". This review summarized up-to-date research on plastic its waste pollution. has domain throughout human life versatile properties such lightweight, high durability, flexibility, low production cost. article describes applications, benefits, production, consumption, classifications plastics. commercialization began Second World War grew all over world within less than century. The global annual more 359 million tons. Despite plastics cause severe environmental public health issues. Accordingly, this study addresses major issues environment health. Plastics can degrade into micro nano sizes, those fine particles are spreadable in air, water, soil. Therefore, both terrestrial aquatic animals go through negative impacts ingestion, entangling, ulcers, reproduction, oxidative stress. Microplastics also due cardiovascular diseases, chronic kidney disease, birth defects, cancer, etc. closing contains developed end-of-life options (e.g., recycling reprocessing, incineration energy recovery, modification reuse, value addition, landfilling) biodegradable non-biodegradable wastes.

Why is Recycling of Postconsumer Plastics so Challenging?

ACS Applied Polymer Materials, Journal Year: 2021, Volume and Issue: 3(9), P. 4325 - 4346

Published: Aug. 23, 2021

The ubiquitous use of plastics has been driven by their combination low cost and properties, but these attributes directly challenge waste management schemes for plastic recycling. Some postconsumer recycling programs are now nearly 50 years old, a significant fraction still finds landfills or other dumping strategies at end life. With the growing concern regarding waste, especially ocean plastics, there is need innovation alternative economic translation to valued product(s) that will promote efficient circular utilization. This review first describes technical hurdles associated with then it focuses on providing an overview emergent recover through new polymer design, processes, chemical transformations value-added products. Specific challenges discussed include sorting separations, product variability including additives, high efficiency/low in which existing petrochemical industry can produce virgin polymers, particular polyolefins. Although wide variety have demonstrated both mechanical means, commercial success different generally limited either performance, large variance key metrics, economics where products match performance materials process expensive. Successful capture likely depend incentives government regulations.

Plastic Pollution, Waste Management Issues, and Circular Economy Opportunities in Rural Communities

Sustainability, Journal Year: 2021, Volume and Issue: 14(1), P. 20 - 20

Published: Dec. 21, 2021

Rural areas are exposed to severe environmental pollution issues fed by industrial and agricultural activities combined with poor waste sanitation management practices, struggling achieve the United Nations’ Sustainable Development Goals (SDGs) in line Agenda 2030. communities examined through a “dual approach” as both contributors receivers of plastic leakage into natural environment (through air–water–soil–biota nexus). Despite emerging trend research, this paper, we identify few studies investigating rural communities. Therefore, proxy analysis peer-reviewed literature is required outline significant gaps related regions. This work focuses on key stages such (i) effects communities, (ii) generated (iii) development sector low- middle-income countries SDGs, (iv) circular economy opportunities reduce areas. We conclude that must be involved future research help decision makers public health threats, catalyze initiatives around world, including less developed
