Received 05 September 2022; Revised 07 December 2022; Accepted 16 January 2023; Published 01 March 2023 Abstract Waste management is an activity to manage residues, by-products, and used items. Handling used cell phones is one form of waste management activity. In developing countries, used cell phones are mostly handled by informal actors, where second-hand market actors for cell phones act as collection points. Some of these activities often affect the environment and the actors' health due to a lack of adequate technology. Hence, a collaboration between informal and formal actors is necessary to handle the used cell phones and reduce the adverse effects. However, several obstacles faced by informal actors can hinder such collaboration. This study explores the inhibiting factors for the collaboration between the informal and formal actors in handling used cell phones. The respondents were 424 informal actors in five areas of the Special Region of Yogyakarta (DIY Province), Indonesia. The results showed that the unavailability of infrastructure and insufficient organization significantly hindered collaboration in the Yogyakarta municipal area. As for the areas of Gunungkidul, Bantul, Kulonprogo, and Sleman regions, there were no significant factors hindering the collaboration. The results of this study can contribute for stakeholders’ consideration related to e-waste handling, primarily used cell phones in Indonesia; thus, the management of used cell phones is safe for the environment and provide economic benefits for the informal actors.

It is important as the increase in e-waste sharply rises every year, especially for developing countries with an e-waste generation rate of around 5% [1]. Managing e-waste properly is challenging. Poor e-waste management will impact the environment and human health [2]. One form of waste management activity is managing used cell phones. In developing countries, informal actors dominate the management of used cell phones, with the second-hand cell phone market as the central collection point. They provide a valuable "front line" service to the majority of the population and are economically influential in developing countries [3]. Katusiimeh et al. (2013) [4] defined the informal sector as an unregistered, unregulated, or simple activity carried out by individuals or families, or community-formed companies, which carry out activities for value addition on a small scale with minimal capital input. The informal sector is out of the state's control [5]. In addition, its existence is generally neglected by academics and regulators [6]. * Corresponding author: smbudijati@ie.uad.ac.id http://dx.doi.org/10.28991/CEJ-2023-09-03-011 © 2023 by the authors.
