programs will operate in the future. This discussion is coming about due to many biosolids processes that
were installed in the 1970s and 1980s under a different era of reuse and regulation and reaching the end of
their useful life.
To move forward there needs to be the establishment of objectives and goals that an evaluation is to be
built around for the future needs of biosolids processing for the owner/authority. The evaluation should
indentify the process that will be the most cost effective in capital and operation and maintenance costs. In
addition, with today’s concerns regarding climate change every evaluation should evaluate the carbon
footprint created by the various processes.
This is a case study of one evaluation done by the author that turned into a thermal dryer project that has
now been in operation for over six years.
