INTRODUCTION ^ 



The utilization of the waste of any industry is desirable because 

 of: (1) The increased profits due to the increased returns from the 

 by-product; (2) the elimination of the disposal problem that is in- 

 creasingly demanding more attention due to the density of population 

 in the industrial areas; (3) the use of valuable and desirable materials
