Two-thirds of plastic waste
comes from packaging
Thanks to Maris co-rotating twin-screw extruders, LDPE or PP base packaging can be recycled to produce films again.
Furthermore, by equipping the extruder with one or more side-feeders, it is possible to add mineral fillers/additives to improve the material properties. In case the material is of post-consumer origin, the extruder is equipped with an automatic screen-changer to eliminate the contaminations.

PP-contaminated HDPE? No problem!
Very often the placing on the market of recycled HDPE is made more difficult by the contamination of PP.
Thanks to Maris co-rotating twin-screw extruders, it is possible to overcome this problem by processing and adding, in different percentages depending on the level of contamination, a polymeric compatibilizer that significantly improve the mechanical performance of the material.
