Body Of Essay
* There are two Types of plastics
a) Thermoplastics b) Thenmosetting plastics (Thermosets)
Thermoplastics have the abiLity to be Continually softened, melted and reshaped or recycled, for example in injection molding or extrusion resins
Thermosets material remain in a permanent solid state after being cured one time. Ex .Silicone, polyurethane, phenolic.
Indio’ alone generates 26,000 tonnes of plastic every single day. Not all plastic is recyclable. Only 15,600 tonnes of this waste is recycled while the rest.Of this waste remains unnollected and is simply left to decompose.
A plastic bag takes a thousand years to dicompose. A plastic bottle, cup and plate takes atleast 450 years. plastic account 8% of the total Solid waste generated in the country annually, with Delhi producing biggest quantity followed by Kolkata, Ahmedabad said CPCB. 2018 report.
Reasons for plastic waste generation.
c)vast network of unlicensed unit manufacturing low grade plastic products
d) Indifference of municipal authorities to waste management
India generates around 5.6 million tonnes of plastic waste annually, how can we as citizens can reduce, this waste and also convert waste to wealth
• ill effeces of plastic waste
a) plastic pollute beaches and oceans – More than 8 million tons of plastic are dumped in our oceans every year. By 2050 we are going to have more plastic waste than fish

e)pyrolysis and energy recovery waste plastic contains energy y 3000 to 8500 kcal/ kg. Pyrolysis convert waste plastic and tires into pyrolysis oil, carbon black and hydrocarbon gas. pyrolysis oil used as fuel to substitute industrial LDO(cost 40-45 rupee / lit). Carbon as fuel in place of coal
-Construction of road out of plastic waste and Pyrolysis technology can be effectively utilized to convert plastic waste from industry to value added fuel.
-To address these issues it requires both ecosystem and it’s individual components. This means that government,companies and business model Come together to address problems of plastic waste.
-Retailers and street vendors should abide the law.
