Question

Disadvantages of polythene utilizations

Answer 1

• Disadvantages:
  
  ▪The polymer takes a long period of time to break down in landfill sites, which we are running out of space for.
  
  ▪These landfill sites destroy greenspaces and habitatsPoly(ethene) is made from crude oil, which is a now renewable fossil fuel. We will gradually run out of this material.
  
  ▪The production and combustion of Poly(ethene) produce a by product of Carbon Dioxide; this greenhouse gas contributes to global warming.
  
  ▪Large amounts of energy is required to produce the polymer.
