|Title: ||The technological economics of collection and landfill disposal of municipal waste in the United Kingdom|

|Abstract: ||Accurate and detailed costs for individual municipal waste
collection, treatment and landfill methods are not readily
available. Neither is there a reliable means of comparing
between two or more alternative options. However, before
improvements to the management and planning of solid waste
disposal can be achieved both are required. Currently,
comparisons and planning in this field are highly ambiguous,
often misleading, with individual operators using widely
different accounting conventions and operating standards.
The purpose of this work has been to establish accurate comparisons.
Initially, detailed financial and technical information \'las
collected from numerous operators, and then a standard basis
for comparison (the "base case") was derived onto which the
costs obtained were adjusted. Cost functions were also
generated to interpret component costs fora range of sizes of
The economics of five collection methods, four transfer methods,
seven bulk transport vehicle types and several landfill disposal
variations are considered. For each a detailed appraisal of
the component capital and operating costs has been made so as
to identify the largest expenditures. The effect of uncertainty
on cost estimates was also emphasised and explicitly considered by
sensitivity analyses on selected economic and physical parameters.
These analyses have indicated those component costs which exert
the most significant influence on the total costs, and as such
should be the most closely monitored by a waste manager. One
notable example is the sensitivity of total landfill costs to
Six case studies are also presented. These are designed to
demonstrate the versatility of the cost models derived and
also the method developed for unambiguous economic comparison.
This research provides a large financial data base on all of
the collection, transfer and landfill methods in common use in
Britain. Use of this information and the principles for
comparison put forward would enable waste managers to
incorporate sound financial appraisals into both their
operational and forward planning decisions. This should
subsequently improve not only the quality of their decisions
but ultimately the standard of service they offer too.|
