Question

creative report on different aspects of pollution caused by polythene bags

Answer 1

ABSTRACT Use of polythene is increasing day by day and now it can be seen that polythene is being used in almost every activity of life. It has been estimated that India's polythene demand is expected to increase by 129 % by 2023. With the increased use of polythene, the pollution level caused by it will also be increased, affecting almost every kind of environment including terrestrial as well as aquatic biome. There are various methods for lowering down the polythene littering; having their own associated pros and cons. Among all other methods biological degradation appears to be the most promising method. Microbes utilize the polythene as source of carbon and use their enzymatic machinery to solubilize it. In this study an array of microbes have been studied for their biodegradation capacity of polythene. Keywords: Plastic, Polythene, Biodegradation, Enzyme, Microrganism. 1. Introduction Polythene or polyethylene is a polymer of ethylene gas (CH2=CH2) which is commonly used in our day to day life like grocery bags, shampoo bottles, bullet proof vests etc. Several kinds of polythenes are known with most having the chemical formula (C2H4)nH2 . There are various categories of polyethylene like low density polyethylene (LDPE), medium density polythene (MDPE), high density polyethylene (HDPE) and very low density polyethylene (VLDPE) (Rivard et al., 1995). Among these LDPE is commonly used for making grocery bags, food wrapping material, power cable sheathing and laboratory containers as it is excellently resistant to dilute and concentrated acids, ketones and vegetable oils. Versatile nature of LPDE makes it major cause of pollution (Usha et al., 2011). It has been shown in figure 1 that India has a large share of 4% of total plastic consumed worldwide and it has been estimated that comprehensive polyethylene demand in India is expected to mount 8.2 million tons by 2023, up from 3.6 million tons in 2013 that would be largest in Asia (www.buisness -standard.com). According to Greenpeace international report (2014) approximate annual production of plastic in world is around 100 million tonnes . This amount is a matter of great concern considering environmental safety. 2. Effect of polythene on different kinds of environments The environment has been classified mainly in to five categories i.e. aquatic, deserts, forests, grasslands and tundra. It is extremely tragic news that polythene is showing it deleterious effects on all major types of biomes. Total plastic waste that is polluting marine as well as terrestrial environment is around 25 million tons, out of which 64% are synthetic plastics
