disposal of manganese dioxide

[lab-woman]

Hi everyone,

Just wondering how I dispose of manganese dioxide that has been mixed with hydrogen peroxide. I only have a very small amount and I couldnt find anything in the CSIS area on disposals.

Also, is Manganese Dioxide still for years 7 to 12? Or is it seniors only now?

Thanks heaps everyone.
