Abstract
La presente invención está dirigida a un método para reducir la acumulación de desperdicios, utilizando un material desechable, ambientalmente degradable. El material desechable, que incluye un polímero que contiene ácido hidroxicarboxílico, se degrada hidrolíticamente durante las etapas operativa y de desecho, de una manera controlada, de manera que el régimen de degradación del material al desecharlo se acelere con respecto al régimen de degradación operativo del material.The present invention is directed to a method of reducing waste accumulation, using an environmentally degradable disposable material. The disposable material, which includes a hydroxycarboxylic acid-containing polymer, is hydrolytically degraded during the operational and disposal stages, in a controlled manner, so that the rate of degradation of the material upon disposal is accelerated relative to the operational degradation rate of the material.
