Abstract

There is no specific management for household hazardous waste (HHW) in Padang City, West Sumatera, Indonesia. HHW management is still mixed with other municipal solid waste; therefore it can pollute the environment and endanger health. Generation unit and composition of solid waste is the initial data required for a solid waste management system planning. This study aims to analyze the generation and composition of HHW in Padang City and calculate the percentage of HHW in the total solid waste of Padang City in 2017. Determination of sample size, sampling method and sample measurement was carried out in accordance with SNI (Indonesian National Standard) 19-3964-1994 on Method of Sampling and Measuring Sample of Generation and Composition of Municipal Solid Waste. According to the calculation of SNI with 97% confidence level, 162 samples were collected from domestic, commercial, institutional, industrial and municipal services sources. The HHW generation of Padang City was 11.875 ton/day (excluding electronic waste) with the generation rate of16 g/cap/day the highest HHW generation was from industrial sources (61.73%), followed by domestic sources (27.62%). HHW composition was dominated by 37% body care and 24% cleaning products use. HHW of Padang City was composed mainly of40% toxic and 19% corrosive. The percentage of HHW in the total solid waste generation of Padang City was 2.2%. Although the percentage was quite small, special planning is required for the HHW management system due to the accumulated effects.
