Le recyclage des matières plastiques : enjeu économique ou mirage environnemental ?

Abstract

Chaque année, dans l’Union Européenne, environ 60 millions de tonnes de matières plastiques sont produites pour des usages dans le domaine du packaging, des textiles et articles de sport, de l’électronique, de l’automobile, ou même du médical. A part quelques exceptions, la majorité de ces matériaux plastiques ne sont ni biodégradables ni compostables, et la question de la gestion de ces matières plastiques, après leur phase d’utilisation, est devenue tant un enjeu environnemental qu’économique. Après usage, certains plastiques de notre quotidien sont incinérés et valorisés en énergie (chaleur, électricité). D’autres matériaux sont par contre recyclés via des filières de collecte et de traitement ad hoc, et réintègrent la chaine de consommation. Si le grand public semble soutenir sans frein ces initiatives de recyclage (au détriment de la voie de valorisation énergétique), diverses questions de fond doivent cependant être soulevées. Est-il possible de recycler tous les plastiques ? Est-ce que les nouveaux bioplastiques (produits à partir de ressources renouvelables) sont recyclables ? Qu’en est-il du coût de recyclage ? Faut-il soutenir la recherche dans les matériaux biodégradables ou bien investir dans les filières de recyclage ? C’est le point complexe que nous abordons aujourd’hui.
