4.47: Explain Problems in the Disposal of Addition Polymers, Including: Their Inertness and Inability to Biodegrade, The Production of Toxic Gases When they are Burned

ADDITION POLYMERS: Formed from the joining of many small molecules called monomers

PROBLEMS WITH THE DISPOSAL OF ADDITION POLYMERS:

s

LANDFILLS - As addition polymers are non-biodegradable, disposal of waste polymers in landfill sites occupy valuable land, and cannot be decomposed by decomposers which causes sites to quickly fill up

INCINERATION - Addition polymers cannot be incinerated as in complete combustion, large amounts of heat energy and Carbon Dioxide is released into the atmosphere, contributing to climate change. Whilst in incomplete combustion, addition polymers will produce Carbon Monoxide reduces the capacity of red blood cells to transport Oxygen, hence a poisonous gas

RECYCLING - Addition polymers can be recycled but will require different polymers to be separated from each other, resulting in a difficult and expensive process
