MODEL SUMMARY AND

RECOMMENDATIONS FOR

FUTURE RESEARCH

20.1 Introduction

The goal of this research was to build a model to better understand and evaluate solid
waste generation rates of companies and government agencies in the United States.
This goal was attained by gathering data, characterizing businesses, and developing
mathematical models for companies and government agencies to evaluate individual
company waste generation. Figure 20.1 displays the research summary. This chapter
discusses the hypothesis testing results, research contributions and limitations, and
recommendations for future research.

20.2 Hypothesis Testing Results

Three hypotheses were investigated that were based on the model concept. The inves-
tigation of these hypotheses guided the research process. A review of the hypotheses
is listed below and discussed in greater detail in the remaining sections:

1 Similar businesses generate similar waste stream compositions and these busi-
nesses can be statistically grouped.
2 Significant variables can be identified that aid in the prediction of annual solid
waste generation rates.
3 Solid waste generation performance parameters can be established.
