CONCLUSION

IMPACTS OF PLASTIC BOTTLE ON ENVIRONMENT :

  • Deadly effect on wildlife
  • Impact on the food chain
  • Groundwater and air pollution


SOLUTIONS :

  • Purchase reusable bags
  • Sort and recycle
  • Drink tap water

How to reduce the impact of plastic bottle on the environment ?

  • Recycle end-of-life bottles

  • Use glass or stainless steel water bottles

  • Drink tap water



  • Use activated carbon as a water purifier if you don't like the taste of tap water

  • Regarding sodas, try to drink less or use solution like a Sodastream



PLASTIC BOTTLE : LIFE-CYCLE ANALYSIS

PET plastic bottle : Oil + Carbon + Water


Impact on environment : Non-renewable resources

How to have Oil : extracted from underground reservoirs using traditional drilling and pumping methods.

Then oil is cleaned at the rafinery.


Impacts on environment : Destruction of landscapes, deforestation, water pollution (oil slick), air pollution by greenhouse gas emissions.

Plastic factory : oil is transformed >> plastic pellets

Then, 3 steps : Extrusion, Molding and Blowing.

Molten PET granules >> injected into a mold to obtain a preform

Preform >> Blown by radial and axial bi-stretching at T°C between 100 °C and 125 °C.


The bottle : brought to the bottling plant and filled with a fluid like water


2 L of Water + 80 g of charcoal + 42 liters of Gas + 100 mL of Oil = one bottle of 1 L.


Impacts on environment : Workers exposed to a complex mixture of chemicals - health risks / emission of greenhouse gases and use of a lot of water



Product >> transported to stores for purchase and consumption.


Impact on environment : Emission of greenhouse gases

The product is then purchased and used until its end of life.



Two possibilities :


  • Plastic bottles : in the trash and end up in landfills (1000 years to start to break down).
  • Recycled and brought to a factory that turns them into other items like carpet, fleece and other plastic items. (27 % of plastic bottles are recycled)
