Industrial hazardous management practices
The bulk of hazardous waste that is generated from smallscale factories is currently dumped into waterways and
land-disposal sites, or stored with little or no previous
treatment. Medium- and large-sized factories are usually
equipped with treatment facilities, but most of these are
inefficient and incapable of treating hazardous waste.
Industrial estates provide waste treatment facilities for their
member factories, but none is known to have complete
hazardous waste treatment facilities.

Because of the lack of hazardous waste treatment
facilities in Thailand, in the early 1990s, the Ministry of
Industry (MOI) strongly encouraged all factories classified
as hazardous waste generators, according to the Ministry of
Industry Announcement No. 25 (1988), to have on-site
storage facilities where hazardous waste could be stored
until treatment facilities were constructed. Many national
and multinational firms in Thailand responded by storing
waste at on-site landfills and in storage facilities. Unfortunately, however, reports of hazardous waste dumping on
public land (i.e., in municipal landfills, or close to public
parks) are not uncommon
