Excessive consumption and global energy demand have generated the need to incorporate plastic and agro-industrial waste into recovery processes, to obtain alternative energy products from thermochemical treatments such as rapid pyrolysis, in which solid, liquid, and gaseous products are generated. The development of methodologies for the recycling and/or recovery of waste generated from various industries, specifically polymer and agroindustrial, is of the utmost importance, given the chronic pollution and environmental impact on natural ecosystems, water bodies and fauna. The objective of this article is to analyze the environmental impacts of the high generation of plastic and agro-industrial waste, and to determine the relationship between the operating conditions and the performance and selectivity of the products generated with the physicochemical characteristics of catalysts used in rapid pyrolysis for the recovery of such waste. This was done through a review of the literature in recognized databases to obtain updated research articles with scientific validity. It was found that catalyzed pyrolysis presents an improvement with respect to the performance and distribution of the products according to the selected active phase in which the nature of the metals used leads to various chemical routes and, therefore, to hydrocarbon-rich products.

Keywords : Rapid pyrolysis; catalytic pyrolysis; agro-industrial waste; plastic waste; waste recovery.
