Abstract: Despite the emphasis on consumption and production patterns in the Sustainable Development Goals (SDGs), plastic pollution remains inadequately addressed. This research contributes to the limited literature on sustainable consumption and disposal of plastic in developing contexts and demonstrates how universities can effectively integrate sustainability competencies into a subject-specific curriculum. This study examined how teacher training programs can address plastic pollution through curriculum innovation and experiential challenge-based learning. Focusing on technology student teachers (TSTs) at a South African institution, the research explored their experiences with community-based problem-solving activities related to plastic consumption and disposal. The polymer module was restructured to combine theoretical knowledge with practical sustainability actions, engaging students in real-world environmental challenges. Data were generated via focus group interview, reflective journal, and photovoice. Working in teams across four communities, TSTs conducted plastic audits in households, shared findings with community members, and collaboratively developed sustainable solutions. This approach bridged the gap between academic learning and environmental action, addressing the critical global plastic crisis that contributes to fossil fuel depletion, ecosystem damage, and greenhouse gas emissions. The findings highlight the potential of teacher education to cultivate environmentally conscious educators who can inspire sustainable thinking and action across educational settings. The practical implications of this research extend beyond the classroom, offering a replicable model for teacher education programs to empower future educators as change agents who can facilitate sustainable community action through knowledge co-creation and context-specific environmental problem-solving.
