Solid waste generation at Pasir Mas district

Abstract

This study discusses the effectiveness of solid waste management and landfill at Pasir Mas district. The objectives of this study are to determine solid waste generation for municipal solid waste (MSW) at Pasir Mas district, to study existing method of solid waste disposal at the landfill as well as problems and challenges that arise, water quality at the landfill surrounding areas and propose for more sustainable solid waste disposal method for this district. The study begin with the process of finding the amount of solid waste volume managed by local municipal council in the year of 2018, 2019 and 2020. Pasir Mas Municipal Council management representatives estimated solid waste collection around 126 tonnes per day. Based on data analysis it is clearly seen that the trend of solid waste collection by month in the year 2018 and year 2019 are quite similar with minimal differences. However the trend of solid waste collection in the year 2020 is still not fully available according to record given by municipal council . This study also focused on the possibilities of leachate in the surrounding landfill area at Kampung Pusu Empat Puloh compared with Environmental Quality Act. So, as a result if compared mean pH value which is 6.61 still in the permissible range value. Chemical Oxygen Demand (COD) mean measure at 59.00 mg/L was within the limit and below the 400 mg/L. However Biological Oxygen Demand (BOD5) mean value was 34.93 mg/L and 74.65% more than 20 mg/L. Lastly, Ammoniacal Nitrogen (NH3-N) mean reads at 0.20 mg/L was below standard of 5 mg/L with percentage different more than 100%. Most of parameters in sampling result acquires on the site gives positive feedback on water quality. It can be conclude that the best alternative for this landfill was by turning it into sanitary landfill which is more efficient and sustainable in handling solid waste.
