For many reasons, but mostly these:
1. Chemicals can react violently (combustion, vaporization, etc.) with each other if they are disposed improperly.
2. Chemicals can form new, unwanted compounds if certain chemicals are disposed together into one container. These new compounds can be very hazardous.
3. Solids, heavy metals, halogentated and non-halogenated waste are each treated differently from each other. Separation of each disposal makes 'clean-up' easier.
4. Environmental safety.Waste all can severely destroy/harm the environment, lowering its safety.

Chemicals must be disposed of properly when the lab is finished so that they do not harm anybody. What if you didnt throw it away and a kid thought it was something else and did something with it?

Because if they get in to a fresh water source they could potentially harm fish stocks and the environment by pollution or contamination.
