Disposal of Addition Polymers (Edexcel IGCSE Chemistry (Modular)) : Revision Note

Disposal of polymers

  • Addition polymers are formed by the joining up of many small molecules with strong C-C bonds

    This makes addition polymers unreactive and chemically inert so don’t easily biodegrade

Disposal of polymers, Edexcel IGCSE Chemistry

Disposal of addition polymers is an environmental problem

Landfills

  • Waste polymers are disposed off in landfill sites but this takes up valuable land, as addition polymers are non-biodegradable so micro-organisms such as decomposers cannot break them down

  • This causes sites to quickly fill up

Incineration

  • Polymers release a lot of heat energy when they burn and produces carbon dioxide which is a greenhouse gas that contributes to climate change

  • Polymers that contain chlorine such as PVC release toxic hydrogen chloride gas when burned

  • If incinerated by incomplete combustion, carbon monoxide will be produced which is a toxic gas that reduces the capacity of the blood to carry oxygen
