The project aims at understanding the different existing technologies for the chemical and physico-chemical recycling of plastic waste. These promising technologies could allow to process hard-to-recycle plastic waste and produce high-quality recycled plastics. However, despite intense communication, little information is currently available to compare these processes with each other and to assess their performance in economic or environmental terms. The uncertainties associated with these new technologies are also high given their early stage of development (often at pilot/demonstration stage). The purpose of this study is therefore to draw up a state of play of the various chemical and physico-chemical recycling technologies via a literature review and to clarify the pending points, notably by means of expert consultations.
The aim of the project is to understand the various existing technologies for the chemical and physico-chemical recycling of plastic waste. These promising technologies could make it possible to process waste that is currently difficult to recycle and produce high-quality plastics (e.g. suitable for contact with food). However, despite intense communication, little information is available to compare these processes or to assess their performance in economic and environmental terms. The uncertainties associated with these new technologies are also considerable, given their current stage of development (often on the scale of a pilot or demonstration unit). The aim of this study is therefore to provide an overview of the various chemical and physico-chemical recycling technologies by reviewing the literature and clarifying the outstanding issues by consulting international experts.
