Abstract—Hazardous wastes generated from a garage and auto service can cause an adverse impact on the environment. Bangkok has an increasing rate of accumulated car registration. The information from the Department of industrial works indicates that 6,109 garages are registered of which 1,440 sites is located in Bangkok. In this study, 4 types of dataset were used to determine type, quantity and management methods of the hazardous waste from garages in Bangkok, including SK.1 (report 1), SK.2 (report 2), the hazardous waste manifest (report 3) and Questionnaire survey. Report 1, report 2 and report 3 from the year 2015 to 2017 were obtained from DIW. Questionnaires were collected from 62 garages in Bangkok. Material flow analysis or MFA was used to analyze the waste management pathways and identify the potential for improvement. The results show that the amount of hazardous waste generated according to report 1 and report 2 are higher than those of report 3 because report 1 and report 2 were the permission quota which each garage has to request from DIW while report 3 is the actual waste disposal. The amount of hazardous waste generated from garages from report 3 was 11,580, 6,031, and 6,267 tons from 2015 to 2017, respectively. Based on the questionnaires, the waste generation rate, are 1.86 kilograms of contaminated fluids, 1.70 kilograms of waste lubricating oil, 0.97 kilograms of automotive parts, 0.86 kilograms of lead-acid batteries, 0.76 kilograms of organic solvent, 0.61 kilograms of metal packaging, 0.61 kilograms of coolant, 0.37 kilograms of contaminated material, 0.36 kilograms of oil filters, 0.31 kilograms of air filters, 0.24 kilograms of hybrid batteries, 0.23 kilograms of non-metal packaging, 0.15 kilograms of hydraulic oil, 0.10 kilograms of oily sludge, 0.07 kilogram of paint sludge, 0.04 kilograms of tire balance, and less than 0.01 kilogram of fluorescent lamp and alkaline batteries per car in service.
