Environmentally Conscious Process

Recycling 100% of our scrap and waste plastic


At Benjamin Mfg. Co. we take pride in protecting the environment as much as we can by recycling 100% of our scrap and waste plastic by feeding it into a granulator (grinder) and producing ground flake. We can sell and/or use the ground flake by reprocessing back into extruded sheet for forming again.
