No, it's curbside collection #2 HDPE and LDPE plastics, there should be no PVC in it... no PET or styrene or PP either. That is one of the things I am going to address tomorrow.Originally Posted by Jpfalt
The water should not be turning acid to this extent. I am recalling my plastic chemistry and PE plastics shouldn't be causing the acid.
It has to be coming from material contamination.
My primary guess would be PVC film cap liners, labels and stuff like that... that is if there is a vinyl contamination.
THAT I can test via flame-test and float-testing.
Second guess would be something like soap or bug-spray or pool chemicals in trace amounts on the waste material reacting with each other and concentrating in the cooling bath.
