Development of a waste sorting system in Morrumbene, Mozambique : Exploring how to engage a community in waste sorting

Abstract: This abstract presents a Master’s Thesis in Industrial Design Engineering conducted on behalf of Project Vita, a non-profit organisation working in Morrumbene, Mozambique. The aim of the project was to develop an implementable waste sorting system that would align with the customs of the community and serve as a foundation for a more advanced solid waste management system. Using a combination of human centred design, design for sustainable behaviour, frugal innovation and holistic design thinking, the project used various methods such as co-creation workshops and live prototyping. Eight weeks were spent in Morrumbene, where solid waste management is a concern due to underdeveloped infrastructure. The main findings from the user study revealed a lack of trust among the people regarding waste management and there were concerns about health risks associated with non-combustible waste, especially glass. However, the people in the community expressed openness to participate in a waste sorting system, especially if it is beneficial for them. Based on findings, it was recommended to initially focus on one single waste category and gradually expand the system. The project resulted in a system plan for glass waste management, considering a short term, midterm and long-term perspective. In the short term, information would be spread to encourage residents to bring glass waste to a bin in a central location. The glass would be used in construction projects conducted by Project Vita. For the mid-term implementation, fundings would be sought for new bin locations. Construction companies would use the collected glass waste as filaments. The long-term implementation would include colour sorting bins and involve stakeholders like glass producers for glass collection and recycling.
