More info


Certain asphalts containing tar and those laid back in the ‘80s and ’90s contain compounds that are today prohibited as they can cause health problems for those who handle or are in contact with them.

It is therefore important to know whether these are present when maintenance has to be carried out, in order to isolate them from other waste. This identification can be carried out by detecting the PAH strongly present in the tar.
