Waste generation in traditional organized bazaars: a case study of organic waste sources in Da Nang City, Viet Nam

Traditional organized bazaars are important retail venues in Viet Nam, but there are concerns about their waste management programs. This study examined five organized bazaars in Da Nang City, Viet Nam, to provide baseline data for improving bazaar waste management. We focused on vendors that produce organic waste and summarized the quantity and composition of waste obtained from ten typical merchandise categories. There were notable differences in the waste quantities and composition between the waste obtained from merchandise categories and bazaar locations. Fish and vegetable vendors and food stalls are major sources of organic waste that can be used for local swine breeding. Overall, introduction of source separation was negatively viewed among vendor clerks. However, it is possible that a small reduction in the garbage collection fee, which is linked to the introduction of source separation, would change their attitudes.
