Problems With Polymers

Polymers can cause many wastage problems because they do not biodegrade (break down naturally).

Landfill sites

Landfill sites

  • When plastics are added to a landfill site, the land becomes polluted.
  • We have to make new sites to bury plastics all the time.
Combustion

Combustion

  • When we combust (burn) plastics to generate energy, many toxic and acidic gases are released into our atmosphere.
  • For example, carbon dioxide is produced, which contributes to global warming.
Difficulty recycling

Difficulty recycling

  • Plastics can be difficult to recycle. There are many types of plastic and, before they can be recycled, they must be sorted in to their different types.
  • Once they are sorted, they can be melted down and reshaped.
Expensive

Expensive

  • All of these processes can be costly.
Biopolyesters

Biopolyesters

  • There is a specific type of polymer called a biopolyester that is biodegradable.
  • The polymers are produced using amide, ester and their functional groups, which allows them to biodegrade.
