Separation by static electricity Dave Hakkens

In this post I will explain separation by static electricity. Another industrial way of separation is static separation. With this method a sample of plastic is dropped between 2 static charged plates, and the amount of static energy the sample absorbs determines the type of plastic E.g. if you want to separate PP and PE, PP will go to the
