How does everyone dispose of their zinc sulphate waste since it is toxic to aquatic life? (I have 0.1M solution )

I put it in my heavy metal waste. It is collected by an authorised company to be disposed of.

okey dokey !
cheers

I pour stuff like that, especially when it's only 0.1M, into an ice cream container and let it evaporate quietly for a while on a shelf in my chem store. That way I end up with much less volume to fill up my heavy metal waste bottle with.

cheers...will do.

I evaporate it as much as possible then put it asdide for use when they make electrical cells with concentrated copper and zinc sulphate solutions.

Good thinking General or is that 99
