Environmental Thesis

Global plastic production is responsible for more than 180MT of waste every year, of which only 15% is actually recycled while the vast majority ends up in landfills, is incinerated or dispersed into the environment.
The current linear model of plastics production, usage and disposal is unsustainable, triggering a concerted effort – promoted by all local governments and global packaging brands commitments – to drive plastics consumption into a circular economy.
Previero recycling solutions represent a key enabler of the transition towards plastic circularity, turning post-consumer and post-industrial plastic waste into high quality flakes with positive impact on material recycled, landfill saved and reduction in CO2 emissions.


Founded in 1922 and based in Anzano del Parco (Como, Italy), Previero is the pioneer in the plastic mechanical recycling space, driving market innovation and delivering benchmarking quality standards. As of today, the company is among the few players capable of offering turnkey recycling solutions covering the entire pre-processing phase (commonly named “from bale to flake”) and addressing all types of feedstocks (i.e., PET, films, HDPE). Previero focuses on R&D, engineering, and assembling/testing activities, which over the years led to a differentiated and integrated value proposition, matching the increasing need of global recyclers to identify technological partners capable of supporting them in the design and commissioning of the full recycling line.
