Advantages and Disadvantages of Plastic
Ullman’s Encyclopaedia of Industrial Chemistry defined plastic as a combination of polymer and additives, which most of the additives added are synthetic and are produced by high technology equipment (2003, pp. 325-336). The history of plastic shows that human being started to use plastic before 15000 B.C. (2003, pp. 325-336). Only after few decades, Alexander Parkers succeeded in finding an easy method to produce plastic which then his invention, Parkesine was introduced in 1862. The demand of plastic continuously increases as Lundsquit confirmed that the production of plastic had increased from 1.5 million tonnes in 1945 to 80 million tonnes in 1989 (2000, p.4). Ullman’s Encyclopaedia of Industrial Chemistry concluded that the rapid growth of plastic production was probably because of the three main factors: the growth of world population, the increase in standard living and the replacement of older materials of plastic (2003, p. 337). Although plastic has a wide range of important industrial applications due to its unique features, mismanagement and unregulated use of plastic bring harm to animal life, lead to

    The plastics industry has been growing at an extraordinary rate of 15 per cent over the years. Thus its potential is being utilized properly. The boost in the plastics industry is due to the rapid growth of segments like electronics, packaging, healthcare and telecommunication sectors. Annually around six million tonnes of plastic is produced in the country, with the plastic packaging sector growing fastest. (Plastic Drum Company, 2011).…

    The manufacturing process of plastic bags commences with the extraction of and handling of raw materials. Large amounts of energy are required to extract crude oil, and most of the electricity used in the process of manufacturing the plastic used in these bags comes from coal-fired power plants (Greenfeet, 2004). The fundamental components of manufacturing plastic bags are petroleum and natural gases (Lajeunesse, 2004), whereby 4% of the world’s total oil production is used in the production of plastic bags (Greenfeet 2004). The toxic emissions and consequently air pollution of chemicals and carbon dioxide during the production of plastic bags presents a serious concern for the environment. According to the Institute for Lifecycle Environmental Assessment (1990), the manufacturing of two plastic bags produces 1.1 kg of atmospheric pollution, which contributes to acid rain and smog.…

    Phthalates are known to be one of the most abundant chemical compounds that act as pollutants in the world and they are commonly found in the environment or in nature where most humans and other living systems are exposed at low levels in air, water, and food specifically di-(2-ethylhexyl) phthalate (DEHP), which is the most commonly used as plasticizers. It was reported that 18 billion pounds of phthalates are produced and used annually and 2M tons of DEHP are produced each year worldwide (Lorz, et. al.).…

    Unlike typical plastics, bioplastics are derived from 100% natural materials such as corn, potato and sugarcane. Often referred to by their chemical constituent such as polylactide(PLA) or polyhydroxylalkanoate(PHA/PHB), (Vidal,2008) the bioplastics industry uses words such as ‘sustainable’, biodegradable, and compostable to depict their products, stating that bioplastics create carbon savings of 30%-80% compared to traditional oil-based plastics. Recently, there has been a great advancement in development of bioplastics and biodegradable and compostable packaging. (Thomas White Global Investing, 2010)Also, the bioplastics industry which just produced 200,000 tons in 2006 will expand to about 5 million tons in 2015 affirms the Germany-based Helmut Kaiser Consultancy.…

    Life in the Plastic Era

    - Hossain Shahriar, Ph.D. The history of plastics goes back more than 100 years - however, compared to other materials, plastics are relatively modern. Their usage over the past century has enabled society to make huge technological advances to take us towards the new Millennium. Pre-20th Century although we think of plastic as a modern invention, there have always been "natural polymers" such as amber, tortoiseshell and horn. These materials behaved very much like manufactured plastics and were often put to similar uses to today's materials - for example, horn, which becomes transparent and pale yellow when heated, was used to replace glass in the 18th century. The original breakthrough for the first semi-synthetic plastics material – cellulose nitrate occurred in the late 1850s and involved the modification of cellulose fibers with nitric acid. Cellulose nitrate had many false starts and financial failures following its invention by a Briton, Alexander Parkes, who exhibited it as the world's first plastic in 1862. Firstly known as Parkesine, then Xylonite, it began to find success in the production of objects such as ornaments, knife handles, boxes and more flexible products such as cuffs and collars. The American Hyatt brothers were attempting to develop a substitute for the ivory billiard ball and in so doing came up with a process for manufacturers using a nitrate cellulose composition. Celluloid was thus born and was patented in 1870 - its early commercial success lay in dental plates for false teeth. In 1912, German chemist Fritz Klatte at Greisheim Electron unknowingly made the first PVC in an attempt to create…

    Global biodegradable plastic production and demand have grown rapidly in recent years, and the capacity reached 1-1.5 million t/a in 2012-2013. Among dozens of biodegradable plastic varieties developed so far, only plastarch material (PSM), polylactic acid (PLA), poly(butylene succinate) (PBS) have realized mass industrial production. In 2013, PSM, PLA and PBS accounted for 87% of the world’s total capacity.…

    Both these varieties of plastics are not biodegradable that cannot be acted by micro organisms leading to the breakdown of the molecules. Generally most of the organic materials such as proteins in human and animal systems, paper, wood, vegetable materials etc. are prone to bacterial action and get putrified leading to mineralization. But it is not possible for any plastic waste material to undergo degradation leading to mineralization. The plastic packing and other waste material will be present in the environment for indefinite time. Hence the disposal of plastic waste material has created a very great challenge to the present generation.…
