Plastic waste recycling product design based on sustainable concepts: study of improvement, developments, and innovations in Kampala City, Uganda

Plastic waste poses significant challenges globally, particularly in developing nations like Kampala, Uganda. This study focuses on innovative product design approaches for recycling plastic waste sustainably. Using quantitative data from surveys conducted in Kampala involving 127 participants, the research finds a moderate preference for recycled plastic products. Specifically, 45 participants expressed openness to using solar lanterns made from recycled plastic, addressing the city's need for efficient lighting. Moreover, a survey on lighting and energy sources, with 52 participants, reveals reliance on a mix of energy sources, highlighting the significance of addressing inadequate lighting. Kerosene lanterns are preferred but have limitations, whereas people frequently use solar lamps. These findings underscore the potential of integrating sustainable design principles into product development to address urban plastic waste challenges.
