Supply and demand projections far mixed office waste paper show that by the year 2000, the practical recovery will significantly fall short of the projected demand. If recovery and demand are significantly out of balance in 2000, deinking plants currently under development won’t be built and/or waste paper prices will increase sharply. To meet growing demand, lower grades of waste paper need to be collected. Raw material costs represent from 25-45% of the operating costs to produce “wood-tree” deinked pulp; therefore, an economic incentive exists to recover lower quality (less expensive) grades of office waste.
This paper describes a method for assigning a value ($/BDT pulp) to five grades of mixed office waste (MOW) based on the percentage of moisture, ash, debris and prohibitives of the material after pulping.
