Description:	The recent boom in the worlds population surpassing the 7 billion mark highlights a problem that is inherent to society, specifically the issue of waste management and the exponential increase in its generation. The adverse effects of mismanagement of the same is profound and has been made evident repeatedly, especially in emerging markets such as Malaysia. Approximately 45% of Malaysian municipal solid waste (MSW) consists of household solid waste (HSW) and 75% of the Malaysian population dwells in cities and suburban areas. Therefore, the suburban HSW component should be given a commensurate amount of focus to curb the interminable waste quandary together with its concomitant problems, namely the emission of greenhouse gases, middling recycling rates and lacklustre reduction efforts. This is ideally accomplished through an upstream approach such as determining HSW generation exactly together with its associated demographic factors, which is crucial in ensuring the efficient application of waste management assets. This study has four main objectives, the first being the quantification of per capita as-discarded HSW arising in selected suburban residential areas of Selangor and Putrajaya via a micro level detailed sampling method. The second objective is to identify the socioeconomic and demographic variables that have a statistically significant association to HSW generation. The third objective is to investigate the potential for HSW reduction, an increase in recycling rate and a decrease in greenhouse gas (GHG) emissions from HSW. The final objective is to assess the efficacy of a direct engagement intervention programme that promotes sustainable 3R waste management practices. Primary arising data was obtained by door-to-door sampling of HSW from 423 houses over a duration of 13 months. The final dataset used for analysis is comprised of 4623 individual measurements from 219 houses. Socioeconomic and demographic data were gathered by face-to-face questionnaire survey that achieved a response rate of 69.03%. The mean per capita HSW arising is determined to be 0.34 kilograms per day. Factors that have a statistically significant relationship to HSW generation are household density, education level, dwelling type and location. The current HSW recycling rate is calculated to be 9.88% which could potentially be increased by another 16.54%. The potential for reduction of HSW stands at a considerable 40.5%. Food waste, plastic bags and plastic PET bottles were determined to be the HSW fractions with the highest potential for the mitigation of GHG emissions. Finally, HSW arising declined by 13.5% after the intervention programme, which is a statistically significant outcome with a moderately large effect size. All of the above constitutes valuable information regarding HSW and denotes that evidently, there is more room for substantial improvements in its management.,Ph.D.,The recent boom in the worlds population surpassing the 7 billion mark highlights a problem that is inherent to society, specifically the issue of waste management and the exponential increase in its generation.
