Recognizing an increase in packaging waste, Austrian plastics recycling equipment manufacturer, EREMA, developed its ReFresher system to produce odorless recyclate. The ReFresher offers filtrated, degassed and odorless recyclates for the first time in post-consumer recycling, even in the case of severely contaminated packaging waste. Post-consumer material is considered difficult to recycle due to impurities and the varied degree of contamination, sometimes caused by migrated substances, such as food and detergent residues. These contaminants often cause an unpleasant odor in the recyclates, as do conventional extrusion processes, which severely limit use in end products. The ReFresher is installed downstream of the extrusion process, and eliminates final odors by keeping recyclates at the required temperature at which volatile materials can be discharged.
