  1. [Music] when we say green chemistry we mean environmentally friendly chemical
  2. processes and doing chemistry with personal safety and the environment in mind there are 12 principles designed to
  3. help make chemistry Greener we will discuss each of these 12 principles with an
  4. example let's start with a simple concept if you keep your room neat and tidy you won't have to clean up as much
  5. if your room gets really messy then you will have a lot to clean up the same concept is applied in green chemistry if
  6. we prevent waste from being produced then there would be less to clean up now this is almost impossible to have Z zero
  7. waste for any given chemical reaction on a global scale the beauty of this principle is that it can be applied to
  8. almost every single chemical reaction conducted for example polystyrene is a fossil fuel derived polymer used to make
  9. all disposable cups and packaging materials the polymer itself needs to be expanded before it can be used in
  10. packaging traditionally this was done with cfc's or chlorofluorocarbons which deplete the
  11. ozone layer now this is done with carbon dioxide waste from other industrial
  12. processes instead of releasing carbon dioxide into the atmosphere and contributing to the greenhouse effect
  13. this is contained and used to expand polystyrene so there is no additional carbon dioxide being released into the
  14. atmosphere for
