cloth using data from the ng hi survey “Consumption behavior towards green growth in urban area of Viet Nam”, ep funded by National Foundation for Science and Technology Development (NAFOSTED) and logistic regression My findings reveal that psychological factors w n towards recycling generally appear to be statistically insignificant Nevertheless, lo ad concern about waste, awareness of inheritance for future generation and satisfaction ju y th of waste condition at household’s residency explain their recycling behavior for yi some materials Another interesting finding is that the household’s belief of money pl gained from waste recycling will lead to recycling paper, carton and plastic al n ua Furthermore, the results disclose that income and age in some cases affect the va recycling behavior negatively Moreover, housing characteristics have impact on n recycling behavior positively in the case of metal, carton and paper recycling fu ll Key words: household waste

INTRODUCTION 1.1 Problem statement t to ng 1.1.1 Real world problem hi In Vietnam, the household waste is a pressing environment issue in recent years ep Ministry of Natural Resources and Environment (2014) indicated that total solid w waste from household was 12.8 million tons per year and would reach to 22 million n lo per year by 2020 Increasing amounts of household waste may lead to the risk of ad heavy environmental pollution and the seriously impact on public health In the y th ju general context, Ho Chi Minh City is facing many challenges in waste management yi Every day, the city has more than 7,000 tons of garbage and costs each year up to pl ua al 235 billion VND to handle Thus, in order to recommend government in the design of effective policies to minimize waste, it is necessary to understand household n n va waste recycling behavior The study analyzes the determinants of household waste oi m 1.1.2 Scientific problem ll fu recycle behavior with the scope of research in Ho Chi Minh City nh Currently, there are few studies on the issue of household behavior in Vietnam, at mainly towards green consumption (water use; energy use; recycling and transport z z choice) Of which, there is only one study of Luu Bao Doan and Nguyen Trong vb jm ht Hoai (2015) on household waste recycling behavior Using structural equation modeling, this study indicated that recycling related to the attitude of the household k l.c have direct relations with the behavior of interest to recycle gm towards recycling Further, general concern and knowledge of environment not om Therefore, the study with logit models may contribute to academic knowledge on an Lu recycling behavior in the context of a developing country like Vietnam Furthermore, this study can provide policy makers with a new perspective on the va nature of recycling behavior, the relationship between this behavior and such factors n behavior towards recycling more ey particular, so that the authority can consider appropriate tools to adjust citizen's t re as psychological factors of the environment in general and waste recycling in 1.2 Research objectives The objective of the study is to identify factors affecting household’s waste t to recycling behavior in Ho Chi Minh City towards six different materials: metal, ng hi carton, paper, plastic, glass and cloth ep 1.3 Research questions Main question: What factors affect household waste recycling behavior in Ho Chi w n Minh City? lo ad Sub questions: y th i Do Socio-Economic and Demographic Characteristics affect household ju yi waste recycling behavior in Ho Chi Minh City? pl ii Do Primary Residence Characteristics affect household waste recycling al n ua behavior in Ho Chi Minh City? va iii Do Psychological factors of the environment and waste recycling affect n household waste recycling behavior in Ho Chi Minh City? ll fu 1.4 Research scope and data m oi The study will investigate determinants of household waste recycling behavior for nh at different materials: paper, carton, plastic, metal, glass and cloth by using data from z the survey “Consumption behavior towards green growth in urban area of Viet z ht vb Nam”, funded by National Foundation for Science and Technology Development jm (NAFOSTED) The survey was conducted in Ho Chi Minh City on April and May k 2014, including 200 households from District 1, 3, 4, 9, Binh Thanh, Go Vap, Phu gm Nhuan and Thu Duc To collect data, investigators directly contacted the household l.c head for an interview, clearly explained the questions and choices, then
