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.

A new use of release coated cellulose or polymeric sheet material and a method for treating release coated cellulose or polymeric sheet material comprising the following steps: (a) Collecting release coated cellulose or polymeric sheet material from producers and end-users thereof, (b) Optionally preparing the collected material by mixing, separating foreign bodies like metals, etc., and feeding it to a dry-grinding station (23), (24); (c) In one or several grinding stations (23), (24) shredding and grinding the materials and (d) Optionally adding additives selected from flame retardant, hydrophobic material, pesticides, minerals nutrients and mixtures thereof and mixing them with the recycled material;
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, pesticide, herbicides, minerals, nutrients and/or mixtures thereof (b) 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 present invention concerns a method for treating waste material comprising: -Collecting release coated cellulose or polymeric sheets from producers and end- users thereof in the form of dense, bulky masses, such as rolls and stacks; -Pre-shredding the dense, bulky masses of release coated sheets into smaller, less dense masses in preparation to the following process steps; -Preparing the pre-shredded material by mixing, separating foreign bodies like metals, etc., and feeding it to a primary grinding station (3); -Grinding the materials into small pieces, of the desired size, preferably down to less than 1 mm; -Adding additives selected from flame retardant, hydrophobic material, pesticide and mixtures thereof and mixing them with the recycled material; -Optionally forming a batt or a sheet by a wet process and/or by adding a binder.
