V. APPROPRIATE LEVEL OF TECHNOLOGY Four levels (minimal, low,
intermediate, and high) of composting technology can be
considered. The particular one which is most appropriate for a
given application will depend mainly on the quantity and types
of material accepted and the site selected, although the
equipment and manpower available are also factors. Table 1
indicates that the lower the level of technology, the greater
the requirements for available space and composting time, but
the lower the cost. The level of technology refers to the extent
to which the ideal conditions for composting are met. Minimal
technology meets the conditions poorly, leading to slow
processing and a strong odor potential. However, if site
conditions permit this type of operation, it can be highly cost
effective. It might be considered for leaves only, or for some
agricultural wastes. The low-level technology provides somewhat
better composting conditions, cutting the time requirements and
odor potential. This is considered acceptable
