200 THE GENERAL APPROACH FOR A SOLID WASTE ASSESSMENT

It is useful to emphasize that the purpose of the worksheet is not a “gotcha game,”
but a method to improve future project estimates and learn from mistakes if applica-
ble. In terms of project duration, the alternatives should be evaluated based on the time
required to implement the alternative versus the original estimate. Explanations should
be provided for large deviations, such as “an additional 2 weeks required to obtain
building permits.” Actual implementation cost should be analyzed versus estimates, in
addition to operating expenses (including labor, materials, and utilities), revenue gen-
eration (from the sale of recyclable material), and cost savings from process changes
or waste hauling costs. The waste reduction volume should be evaluated in a similar
manner. For example, if the purchase of a cardboard baler was expected to reduce
cardboard waste by 20 tons per week and the baler is only reducing the waste stream
by 12 tons, a root cause analysis should be conducted to explore and improve the devi-
ation. Any cycle time or productivity deviations from the original estimates should
also be explored. These deviations could have a very negative effect on the organiza-
tion’s profitability and in most cases are very closely watched by upper management.
The same goes for product quality. Finally, any safety concerns should be addressed
immediately. A walk though by the team leader, safety captain, and area supervisor
can quickly identify and resolve these issues. To aid in the validation process a work-
sheet is provided in Fig. 8.36. The validation process should be performed within 4 to
8 weeks of implantation.

8.14 Monitor and Continually

Improve Performance

After the waste minimization program has been implemented and validated it must be
monitored on a periodic basis to ensure that it is still performing as planned and to make
any necessary adjustments. This includes monitoring the waste reduction amounts and
operational, and financial performance versus the goals. In addition, emphasis should
be placed on continuous improvement to enhance current waste reduction programs
and to identify new opportunities. It may be beneficial to conduct period waste assess-
ments, facility walkthroughs, or employee interviews by the original waste reduction
team to accomplish these goals. When evaluating the program it is important to

■ Keep track of program success and to build on past successes.
■ Identify new ideas for waste reduction.
■ Identify areas needing improvement.
■ Document compliance with state or local regulations.
■ Determine the effect of new additions to the facility or program.
■ Keep employees informed and motivated.

In addition, consider reviewing the organization’s waste removal receipts and pur-
chasing records on at least a quarterly basis to ensure that the waste minimization
