Waxed paper is being used more and more every day in many ways. Its principle purposes are as wrappers or containers either to keep moisture out or in. Its uses vary from bread wrappers and drinking cups to metal parts wrappers.
For the most part, after the paper is used for its original purpose it is discarded and not salvaged like other waste paper. Also at the wax coating mills, the broke cannot be reworked with fresh stock. In most cases it is taken out and burned - not only being a total waste of stock but also a waste of wax and labor.
Therefore, several attempts have been made to recover the fiber and paraffin from this waxed waste. This thesis is a review of those processes which have been found.
The paraffin wax used in the waxed paper industry is a petroleum product; it is obtained only from the crude oil of a paraffin base. It consists of a mixture of saturated hydrocarbons havings similar formulas ranging from about C23H48 to C35H72. The wax is produced by the refineries in three stages of manufacture - 1. Crude wax which is not used in the coating of papers, 2. Semi refined wax for wrapping products which would not be contaminated by it (metal parts, etc.) 3. Fully refined wax which is most generally used. This is free from oil and is odorless and tasteless.
