The objective of this study was to estimate the optimum scale of PLMTP(Public Livestock Manure Treatment Plant) for the efficient management of public sector by long-run cost function.
An economic analysis was performed using the survey of 52 PLMTP records collected by Ministry of Environment in 2007. The main results obtained in this study can be summed up as follows.
The optimum scale under given environmental conditions turned out to be 180~200m?day which is almost 1.5~1.6 times of the average scale of sample plants, 146m?day. This gap between the optimum and current scale suggests that there remains the possibility of further expansion of scale.
