How to deal with waste?


Hey guys, I am currently studying Chemical Engineering at my university and I've been wanting to do my own reactions and extractions on the side when I'm on break. How do you guys deal with waste considering that subscriptions to companies are quite expensive?

Sadly my University runs a very tight ship when it comes to waste, so dumping it off there isn't an option.

There are many threads on this topic here on SM,
the general principles are;

. choose reaction paths that use the least toxic reactants and produce the least toxic products

. use minimum quantities required to get the desired result

. research your reactants and products - dealing with waste should be obvious based on this knowledge

acids, bases, oxidants and reductants can be neutralised

things such as heavy metals;
convert to insoluble salts, dry, mix into small concrete blocks for disposal.

solvents should ideally be recovered for further use by distillation etc.

For each planned experiment you can ask here on SM for specific advice.

- Buy ice cream
- Eat the ice cream
- Clean the ice cream boxes
- Buy concrete
- DO NOT EAT THE CONCRETE.

But I'm sure from there you'll figure it out :)

There's also the option of dîsposing of your (solid) waste by putting it in a sealed container and then filling said container with expansive foam.
Keep in mind one of the properties of expansive foam is that... it expands ! And if you empty the canister and then remove the plastic straw... oh boy...
