1.3. Organic fertilizer. Among the five options, the
production and sale of organic fertilizer is the simplest
method of pig waste management. It also requires little
initial investment. In order to produce a saleable commodity,
large pits are filled with pig waste which is
then dried out. The resulting odour is, however, offensive
to those living in the neigbourhood. Moreover,
during the rainy season, this technique fails to work
effectively and excess waste overflows the pits. It is
unsatisfactory because it does not prevent serious pollution
of the environment. Recently, the local government
has tried to enforce protective regulations such as
the Ministerial Notification on Livestock Farm
Standards of Thailand (1999) which was launched by
the Department of Livestock Development. This law
requires the farmers to take measures to control pollution
and prevent epidemics. The farm’s waste such as
garbage, carcasses, manure and waste water must be
properly disposed of.
