Abstract:
A process for recycling waste materials including waste paper and polymeric waste material comprising the steps of:a) introducing said waste paper, polymeric waste material and water into a pressure vessel mounted to rotate about an inclined axis equipped with suitable agitating means to thoroughly mix said solid waste; b) introducing into said pressure vessel suitable chemical aids to facilitate defibering of the paper fraction of said waste; c) agitating said waste materials in said vessel by way of said agitating means at an elevated temperature and pressure for a sufficient time to accomplish repulping of the moisture absorptive paper fraction, such that the separation of component fractions by density and size can thereafter be accomplished; and d) discharging said separated waste materials from said vessel, whereby said pulped paper fraction is substantially defibered and substantially free of said polymeric waste material and said polymeric waste material is generally agglomerated and operative to concentrate contaminants including color bodies from said waste.
