Banjong Sookdee, deputy city clerk, said three city landfill sites at On-nuj, Sai Mai and Nong Kaem take 9,600 tonnes of garbage a day.
Private operators have been hired to transport some garbage from Bangkok to be buried in nearby Chachoengsao and Nakhon Pathom provinces while about 1,000-1,200 tonnes of fertilizer are produced from recycled garbage.
About 1.5 tonnes of dangerous garbage are handled by a BMA-contracted private company and contagious garbage from hospitals, about 32 tonnes daily, is managed by Krungthep Thanakom Company, he said.
Industrial garbage is destroyed by the Industrial Works Department.
Mr Bangchong said the BMA helped put out the fire at a landfill site in Praeksa sub-district of neighbouring Samut Prakarn last week.
Toxic fumes from the site had spread to several areas in Bangkok.
