Abstract
La presente invención se refiere a procesos para degradar productos de plástico y a los usos de los mismos. Los procesos de la invención comprenden en particular una etapa de amorfización de un producto de plástico antes de una etapa de despolimerización. Los procesos de la invención son particularmente útiles para degradar un producto de plástico que comprende tereftalato de polietileno y/o ácido poliláctico. La invención también se refiere a un método de producción de monómeros y/u oligómeros a partir de un producto de plástico que comprende al menos un poliéster, en particular, tereftalato de polietileno y/o ácido poliláctico, que comprende someter el producto de plástico tanto a una etapa de amorfización como a una etapa de despolimerización.
