Abstract:
This study is a research survey aimed to identify the environmental performance
indicators (EPIs) for non-standard systems and standard systems of swine farms and analyze
the evaluation of environmental performance for non-standard system and standard system of
swine farm. The study was conducted on 8 swine farms in Ratchaburi province and Chonburi
province. Five operational performance indicators (OPIs) were conducted: waste discharge to
water resource, natural utilization, sludge / excrement, unpleasant odors and mosquitoes and
flies. Moreover, the management performance indicators (MPIs) - environmental policy,
environmental problems aspect, legal and regulation, training, and complaints - were included
in this study. Environmental risk assessment was used to identify the significant
environmental aspects, and the environmental performance evaluation.
It was found that there were 5 groups with 12 operational performance indicators
for standard and non-standard system of swine farms. The management performance
indicators could be placed in 5 groups and there were 8 indicators for standard and
non-standard system of swine farms. In the environmental performance evaluation for swine
farms it was found that 4 farms were fair and 4 were needed to be improved. Management
performance evaluation of swine farms also found that 4 were fair and 4 were needed to be
improved. The results of t- test compared with the standard system farm and non-standard
system farm found that pH, BOD, COD, SS, TDS, TKN, PO4, water utilization and electric
utilization had no statistic difference at the significant level 0.05. Meanwhile, the amount of
sludge/excrement had a statistical difference at the significant level 0.05.
