Separation processes of polyethyleneterephtalate (PET) and of vinyl polychloride (PVC), by dry way, in mixtures flows of glass wastes

Several separation processes by dry way of glass wastes (PVC, PET) mixed flows are described. Some of them apply to whole bottles flows, crushed or not. Others apply to milled samples. All these processes depend on a distinction of matters, either at the level of their thermomechanical properties (shocks resistance, compressibility, drilling aptitude, rebound, friction coefficient and/or sticky power) or at the level of the spectroscopic properties (interaction with the X radiations). In this work are particularly described how from a differentiation of the matter properties, a process allowing a separation has to be imagined. We have to take into account of the desired capacities, of foreign matters, of heterogeneities at the level of each matter, of the desired purity degrees of the separated matters.
