Abstract

n Malaysia, 8.33 million tons of food waste was generated in 2015, and 70% of the wastes have been sent to landfills daily. Since most food wastes are disposed to landfills, it lead to methane generation resulting in a significant greenhouse emission. Thus, in this study, the food waste survey was conducted focuses on Gombak residents purposely to characterise food waste disposal survey data and study the effect of household size on amount of food waste generated daily using SPSS software (IBM SPSS v26). In this study, quantitative research was adopted by using the online survey tool, Google form to collect sufficient data. The results revealed that most respondents with a household size of 3 to 4 and more than 4 dispose of less than 500g of food waste daily, representing 54.3 percent and 50.0 percent, respectively. About 37.1 percent of respondents from the household size of 3 to 4 responded that they dispose of less than 1kg of food waste daily. In contrast, another 23.7 percent of respondents with more than 4 people dispose of less than 1kg of food waste per day. This result suggests that many people in the family did not necessarily affect the amount of food waste disposed of daily. The SPSS analysis result (size of sample=80) did not support the hypothesis that household size positively the amount of food waste disposed of daily. In this case, limitations such as time constraints leading to low sample size and respondents did not weight their food waste were the main reasons for the failure in rejecting the null hypothesis.
