This sentence is not correct.
Unfortunately, I cannot give you a proper version, but I can mark some things that look wrong to me:
Is put the toxic waste in soil,where can we bury its?
But even if you correct these three mistakes, I will be surprised to see an understandable sentence
Let me think again:
It puts the toxic waste in soil. Where can we bury it?
Maybe this one is correct, but I have no idea to be honest...
