Description du projet :
Large amounts of plastic waste resulting from a non-circular plastic life cycle, generated from fossil crude oil, represent one of the major environmental issues today, polluting the environment in controlled or uncontrolled waste deposits or generating CO2 in incinerators. In spite of common efforts to improve waste
collection, according to the Federal Office of Environment [FOEN2023] the recycled fraction of today's plastic waste generation remains at 50%. Various recycling processes for specific polymers are presently under development (various start-ups have been founded thereupon), but require highly selected materials as input, which is the common major issue of nowadays plastic recycling. All newly proposed processes rely on high quality waste separation, which is mostly done manually to achieve the required purity levels. Thus,
mixed plastic waste remains the major issue. Non recycled plastic waste ends usually up in the incinerators (in Switzerland) and generates CO2 emission into the atmosphere or on controlled (or uncontrolled, 3rd world) deposits, polluting the environment.
Even though Switzerland occupies a leading place in recycling household waste, just about half of plastic waste is recycled while the other half goes into incinerators [FOEN2023]. Plastic is a material which due to its light weight and versatility cannot easily be replaced in most applications, neither in industry, packaging, domestic, construction, mobility, etc. Thus, Switzerland has made a clear commitment to integrate the plastic material into the emerging circular economy. Nowadays less than 7% of products in Switzerland are resulting from a circular economy [Spörri2021, Keys2023].
