28.2 Waste Management Goals

and Opportunities

The majority of solid waste generated by this sector is paper pulp and mixed paper
wastes. Table 28.1 displays the composition breakdown based on survey results.
As shown in the table, the recycling rate for this sector is approximately 37 percent.
Paper pulp constitutes the majority of the solid waste stream. As derived from the solid
waste evaluation model discussed in Chap. 12, the equation that estimates the annual
waste generation per year per employee for this sector can be calculated from the fol-
lowing:

Tons of solid waste generated per year = 6.63 × number of employees
− 3.51 × solid waste disposal cost per ton
− 114.82 if the company is ISO 140001 certified
+ 340.27
