Influence of lubricant oil residual fraction on recycled high density polyethylene properties and plastic packaging reverse logistics proposal
Abstract To recycle post-consumer HDPE contaminated with waste lubricating oils, companies include prior washing and drying in the process. This consumes large amounts of water and energy, generates significant effluent requiring treatment. This study assesses lubricating oil influence on HDPE prope...
