Sanitary landfill must be truly sanitary

Today, we visited the Bukit Targar Sanitary Landfill, Selangor. It deals with 2500 tonnes of solid waste (rubbish) a day.  Hitherto, we have found it sanitary.
      How many sanitary landfills are there in Malaysia? Some say there are only three. Others mention there are 8. The Government must ensure that sanitary landfills are truly sanitary.
