35.2 Waste Management Goals

and Opportunities

The majority of solid waste generated by this sector are paper and wood. Table 35.1
displays the composition breakdown based on survey results.
As shown in the table, the recycling rate for this sector is approximately 37 percent.
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 following:

Tons of solid waste generated per year = 7.32 × number of employees + 153.2

35.3 Economics

From an economic standpoint, rising fuel costs have had a signification impact on the
logistics and transportation section. These additional costs have reduced available cap-
ital for improvement projects, including environmental initiatives. In such conditions,
