Hi, I have a couple pounds of potassium hydroxide that I need to dispose of safely.

 

I have basic DIY safety equipment and outdoor spaces.

 

How should I proceed?

Well, I've kept it so long waiting to find a use for it that it has begun eating through the plastic containers it was shipped in.

KOH reacts with CO2 from air creating K2CO3 and KHCO3.

If you will have it in solution, with ready access of air (attach air pump for aquarium, if you want to accelerate it),

it will happen spontaneously.

 

Do you have it in solution or solid?

 

If it's solid, keep it in hermetic container (it catches water and carbon dioxide from air).

If it's in solution, you can boil entire water, to turn it to solid, and keep this way.

Did you try making auction on f.e. eBay?
