Breaking new ground in the realm of sustainability research, this study delves into the ‘profit-for-impact’ model’s dynamics through a compelling lens – the case of TONTOTON, an innovative player in plastic neutralisation that has operationalised the model in the context of Vietnam. Interwoven with insights from the natural resource-based perspective and sustainability literature, the research probes how this practitioner-instigated business philosophy aligns with sustainability’s key pillars, charts its sustainable course and envisions its evolution. Semi-structured interviews conducted with TONTOTON’s leadership and a pivotal external business ally were subsequently dissected through qualitative content analysis and data structure, thereby unveiling 14 conceptual dimensions. These dimensions, where partnerships and tangible accomplishments emerge as central themes, conceptually illuminate and demonstrate the profit-for-impact model’s value and further potential for fostering engagement, catalysing problem-solving, and harmonising with sustainability principles while yielding enduring benefits. These findings contributed to crafting a conceptual framework underscoring theoretical and practical implications.
