Abstract
The present invention relates to a method for treating a plastic and/or paper waste material having steps including collecting a plastic and/or paper waste material, preferably paper, and highly preferably a release coated cellulose or polymeric sheet material. The material already includes a selected new-use additive preferably selected from flame retardant, hydrophobic material, pesticide, herbicides, minerals, nutrients, and/or mixtures thereof. The method includes the step of preparing the collected material by mixing, separating foreign bodies like metals, etc., and feeding it to a grinding station. The method also includes the step of, in one or several grinding stations, shredding and grinding the materials into small pieces.
Claims5
A method for treating a plastic and/or paper waste material comprising the following steps:
- (a) collecting a plastic and paper waste material comprising a release coating on a cellulose or polymeric sheet carrier material, said plastic and paper waste material comprising selected new-use additive selected from hydrophobic material, pesticides, minerals, nutrients, herbicides and/or mixtures thereof;
- (b) preparing the collected plastic and paper waste material by separating foreign bodies, and feeding the prepared material to a grinding station;
- and
- (c) shredding and grinding the prepared material at the grinding station into small pieces to mechanically separate a fraction of the release coating from the sheet carrier.
A method for treating waste material comprising the following steps:
- (a) collecting release coated cellulose or polymeric sheet material from producers and end-users thereof, said material comprising a selected new-use additive selected from hydrophobic materials, herbicides, pesticides, minerals, nutrients and/or mixtures thereof,
- (b) preparing the collected material by mixing, separating foreign bodies including metals, and feeding the mixed material to a dry-grinding station;
- and
- (c) grinding the mixed material at the dry-grinding station;
- (d) separating a fraction of a release coating from a sheet carrier in the absence of chemical treatment of the mixed material thereby separating an incoming stream of the mixed material into a first, carrier rich fraction and a second, release agent rich fraction.
