Why in NEWS

  • The study from the University of Bonn in Germany, published in the journal Environmental Research Letters, suggests that shifting to plant-based plastics could have less positive effects than expected.

Consumption

    • It is estimated that by 2050, plastics could already be responsible for 15% of the global CO2 emissions

Bioplastics

  • Bioplastics are plastics derived from renewable biomass sources, such as vegetable fats and oils, corn starch, straw, woodchips, food waste, etc.

Advantages 

    •  Reduce human carbon footprint
    • Reduction of non-biodegradable waste
    • No adverse change to flavour or scent in food
    • Increased energy savings
    • Bioplastics are in principle climate-neutral since they are based on renewable raw materials such as maize, wheat or sugar cane.

Assumption doesn’t hold true

  •  Environmentally friendly alternative.
  •  Change land use globally.
  • Conversion of forest areas to arable land.
  • Forests absorb considerably more CO2
  • Massive deforestation
  • Not all bioplastics are easily degradable
