In the pharmaceutical and material industry, there is often a multi-step process to synthesize a product to be sold. Depending on how many steps there are and how efficient each step is will determine what kind of overall yield the process has. In efforts to improve efficiency and reduce waste, often companies will work on “greening” their processes.

Instructions
For the discussion, research and read about Green Chemistry principles and discuss some real-world examples. In order to do so, do the following:

1 Read about the 12 principles of green chemistry from this website.

2 Pick one of those principles and explain it in detail. put the principle within your Subject heading. First come first serve, if your principle has already been discussed make sure to explain it from a different perspective. How would you explain it to someone who is new to chemistry?
3 Give an example of how that principle is used or can be used. Be specific and cite your sources.
4 Which principle do you think is most useful in impacting percent yield?
5 Which principle do you think is the most important? Why?
