PLASTIC RECYCLING BY ROTOGRAN INC
The purpose of granulation is to create a solid building block that is consistent throughout, this way it can be used for future products. If not granulated and simply melted down, smaller plastic pieces will be more concentrated at the top, while larger plastic drums will stay at the surface of the mix, this results in inconsistency in the melted plastic. In order to eliminate any of these flaws, the plastic is firstly finely granulated.
