Households’ behavior and social-environmental aspects of using bag dustbin for waste recovery in Tehran

Abstract

The suitable dustbin can cause a significant increase in household participation in separated dry waste at production source and recycling rate. This study was conducted on 100 households in Tehran for two weeks for households' wastes without any intervention. After two weeks, the tough-flexible bag dustbins were delivered to the families. At the next stage, by analysing the separated dry wastes by households, comparing the cost of new bag dustbin with plastic garbage bags, and completing some questionnaires, it was concluded that about 92% of households believed that waste bag dustbin was much more accessible and hygienic. The use of plastic garbage bags was decreased an average by 2, after using new bag dustbins. Moreover, the use of bag dustbins has more cost-effectiveness rather than plastic bags (about 54%). Before and after the intervention, the source separation and recovery rate was 0.19 and 0.18, respectively. The amount of wet waste in the waste bag dustbin was decreased to 62.26% after the intervention. The decrease of wet waste in the separated dry waste enhanced the quality of recycled materials.

In-depth analysis to develop a social marketing model to promote women's participation in waste segregation behaviour: A qualitative study

“…This problem was raised in the stakeholder interviews and the low budget of the waste management organisation for training was cited as a reason for this. In other studies, door-to-door education was effective [ 55 , 58 , 61 , 62 ].…”

“…Situational factors such as convenience tools can encourage residents to separate waste [ 51 ]. The study by Amanidaz et al found that the provision of facilities increased waste separation [ 58 ]. In Zhang's study, environmental factors were predictors of people's waste separation behaviour [ 12 ].…”

Effect of Household Interventions on Promoting Waste Segregation Behavior at Source: A Systematic Review

“…Two interventions accounted for the largest sample sizes (1000 and 6580) [34,40]. However, in two studies the number of participants was less than 100 cases [50,53], and in three studies it was 100-102 participants [43,45,49]. Most studies had a volume of 144-680 subjects.…”

“…Using a questionnaire and measuring the weight of recyclable materials certainly increases the validity of the study results, as self-reporting increases the probability of error. In several studies, the composition of recyclable materials was measured, and the highest amount included paper and cardboard, newspaper, plastic, and glass; moreover, clothing and rubber were included, which were the lowest-amount groups [13,49,53].…”
