GRINDABLE PELLET

摘要

This invention relates to a method for producing a pellet suitable for grinding into a fine powder including the steps of: (a) forming a waste feed stream comprising: (i) a polymer component A comprising, relative to the total weight of the waste stream, at least 25 wt.% of a plastic film component B having a cross sectional area (A) to length (L) ratio of less than 0.2 and (ii) a cellulose component C of at least 20 wt.%, relative to the total weight of the waste stream, (b) pelletizing the waste stream with a pelletizing device such that at least part of the plastic film component B is converted to component D, having a A/L ratio of at least 0.2, by chemical and/or heat treatment. The pellet has less than 15 wt.% component B relative to the total weight of the pellet and in which component D, if heat treated, is derived from plastic film component B which has been no more than partially melted. The invention also relates to the pellet thereof and its use as a fuel source.
