In the field of polymer recycling, chemical recycling appears to be a recovery route which could contribute to achieve the objectives of the 3R decree, in terms of setting up operational recycling sectors. This type of recycling will therefore be the subject of this V2P Workshop.
Among the chemical recycling processes for polyolefins, gasification, pyrolysis or cracking can make it possible to produce reusable, recoverable molecules, particularly in the polymer sector, thus distinguishing themselves from incineration, which remains a widely used means of energy recovery. and waste disposal. Among these technologies, we will focus on pyrolysis, which is the subject of much recent work and investment but which remains a source of questions. This process could be used to process large masses and a wide variety of products while meeting, in part, the criteria of the circular economy. It would also provide polymer grades that comply with the most demanding regulations, for example cosmetic and food regulations.
To understand the positioning of this technology in the field of recycling, compare it to already existing technologies, define its limits, we will discuss key indicators such as : energy balance, material balance, GHG emissions, costs, rate of reusable material in the same sector (mass balance, etc.), discharges and pollutants. The required treatments upstream of the process, and more particularly the preparation of waste and sorting, need also to be questioned, because they can significantly impact material yields, costs or even the environmental impact.
After presenting a fairly general picture integrating the regulatory aspects, the communications and testimonies from both academics and industrials will shed light on the scientific, technical and economic obstacles to be overcome. A round table will conclude this day and should make it possible to position pyrolysis among the solutions for recovering so-called “non-recyclable” plastics and rubber.
Who may attend ?
The workshop is primarily aimed at academics and industrials of the polymer community, as well as students (M2 or thesis) interested in recycling.
The workshop is accessible in person or remotely and registration is mandatory regardless of the method chosen.
The amount of registration fees is linked to the method of participation and whether or not you are a member of the GFP.
