Pre-Engineered Recyclable Products

Patent Granted A method for treating a plastic and/or paper waste material comprising the following steps: (a) Collecting a plastic and/or paper waste material, preferably paper, highly preferably a release coated cellulose or polymeric sheet material, said material already comprising selected new-use additive preferably selected from flame retardant, hydrophobic material, pesticides, minerals, nutrients and/or mixtures thereof (b) Optionally preparing the collected material by mixing, separating foreign bodies like metals, etc., and feeding it to a grinding station; (c) In one or several grinding stations shredding and grinding the materials into small pieces. The key difference of the present invention with previous attempts to recycle plastic and/or paper waste material such as release coated sheet material, is that the recyclable release coated sheet material composition is already formulated with an additive being key to the functionality needed for a given new use of the recycled product. A preferred additive for paper waste material are fire retardants. Recycled material obtained from the method discussed above can be used in various applications facilitated by the new-use additive which was already incorporated into the formulation of the waste material composition. First, the thermal and acoustic insulating properties thereof can advantageously be used for insulating thermally and/or acoustically any of: - a wall, panel or roof in the field of buildings, - a panel in the field of transportation, - a sound dampening wall along roads; - a quilted piece of garment or blanket, or for filling - a mattress, or upholstery, - a package in the field of packaging and storage and transportation of goods.
