Printed paper waste

The mixed board and flexible packaging material (MB/EP) consisted solely of printed production waste. The main components were cardboard, paper, plastics, metallized foil, and laminated aluminum foil. [Pg.267]

Figure 1 explains the methodology with an example for the pulp and paper industry. The SEC is depicted as a function of the ratio between the amount of pulp produeed versus the amount of paper produeed. This aceounts for differences between eountries in the use of waste paper as a feedstoek for paper production and in import/export patterns of the energy-intensive intermediate pulp. In the graph, called the stracture/efficiency plot, both the actual (national average) SEC and the referenee SEC are shown (respectively, the upper end and the lower end of the vertical lines in Fig. 1). The diagonal line represents the reference SEC at various pulp/paper ratios for a given product mix (such as high-quality printing paper, wrapping paper or newsprint). The reference level of individual cormtries may differ from this line if the manufactured product mix within a cormtry is different (such as for country C).

Willhoft A proposed process for making aluminum chloride from the solid waste from paper mills. The waste is mainly a mixture of clay with cellulose. It is dried and calcined in an inert atmosphere, giving a mixture of clay and caibon which chlorinates readily. Conceived by E. M. A. Willhoft and briefly examined by the Research Association for the Paper and Board, Printing and Packaging Industries (PIRA) in England in 1977, but not piloted. [Pg.291]

Under no circumstances should prints be allowed to wash for more than one hour the prolonged immersion in water will weaken the fiber of the paper shortening its life. All of your archival processing will be a waste if the paper begins to come apart in 20 years. [Pg.202]

It also keeps the pH buffered in the alkaline range required for the peroxide bleaching of pulp. Sodium silicate has also become an important ingredient of the chemical formulation for the de-inking of printed waste paper. [Pg.1196]
