Abstract
This research work analyzes the process of determining post-consumer contaminant material for plastics and identification of acceptable material to be reused. Burn tests were carried out on recycled material (different plastic wastes) in order to recognize, by means of color change, the type of raw material that is contaminating and thus avoid its entry into the recycling process. The burning was carried out in a thermoreactor at a temperature of 230°C for 30 minutes, with methods and equipment used in a well-known company in the region. In this study, waste from some well-known brands used in homes in the state of Guanajuato was used, considering that the separation was supported by TOMRA equipment and manual classification by the company's personnel. For the burn tests, plastic trimmings were used, elaborated in a handmade way, therefore, the work of a mechanical shredder will not be taken into account.
