Abstract A new approach to waste recycling called “waste bank” has recently appeared in Southeast Asian countries. Typically, waste banks allow members to exchange recyclable materials for revenue, with different returns based on the type and weight of the materials. However, participant numbers remain low, and improvements to the system are necessary to encourage participants to separate their waste. The aim of this study was to determine the factors that influence the period of participation in a waste bank in Malang City, Indonesia. A sample of 216 participants was obtained for the correlation between variables and a multiple-regression analysis. It was found that many respondents were frustrated by the volume of items requiring separation. We suggest that the number of recovery items without substantial economic benefit should be minimized to encourage participants to separate and bring their resources and to participate regularly. This would also be helpful in prolonging participation periods. Many participants regarded the waste-separation concept as an unfamiliar one. Our results may be useful for other Southeast Asian countries at the same economic level as Indonesia who wish to encourage the establishment of waste banks.

Introduction Because of the increase in waste generated by urbanization and economic growth, the shortage of space for landfilling waste in developing countries has become a serious issue, along with associated problems such as water contamination by leachate from open waste-dumping sites [1]. Municipalities in developing countries cannot afford to use costly incineration techniques to reduce municipal solid waste (MSW) volume; therefore, alternatives to the existing waste management system that reduce the amount of waste transported to landfill sites are urgently required.

countries, informal sectors such as scavengers, garbage truck helpers, and itinerant buyers currently play important roles in the recycling of resources from MSW and the reduction of landfilling waste [2–5]. However, the effectiveness of these activities in increasing waste recycling is limited, and large amounts of recyclables continue to be landfilled. Several researchers have reported on small-scale waste recycling systems implemented by local communities in developing countries [6–
