    Exploring the intersection where business models, a circular economy and sustainability meet in the waste economy: A scoping review
    (Sustainability, 2022) Hoffman, Marlin; Schenck, Catherina J; Herbst, Frederick
    The authors endeavor to investigate the intersection and relationship between sustainability, business models and a circular economy. These three concepts are believed to be at the heart of finding a solution to creating and implementing a circular economy. The three pillars of sustainability (society, environment and economics) have been identified as the golden thread when applied to developing circular economies and the business models used in these circular economies. These three pillars highlighted the areas of intersection and engagement between the circular economy and business models. The three pillars, or stakeholders, need to be considered equally and, where there is sacrifice and benefits, they need to be balanced. A scoping review was chosen, as the starting point, to ascertain the literature in the field. The results of the scoping review showed a lack of research conducted at the point of intersection between these three fields. Finding a solution by creating and implementing a circular economy will have positive effects on the economy, environment and society, as there is, proverbially, “not much time left” and everyone in the process will sacrifice and benefit. The research has highlighted the need to explore the intersection and relationship between sustainability, business models and the circular economy as a concept, and future research should develop frameworks to guide the development and implementation of this intersection to include all relevant stakeholders.

    The value chain and activities of polyethylene terephthalate plastics in the South African waste economy
    (SAGE, 2020) Hoffman, Marlin; Schenck, Catherina
    Value chains in their entirety, within the South African context, have not been the focus of much research thus far. A plethora of research has been done on the various actors within the value chain, but the rest of the value chain has not been identified and depicted. Failing to understand and describe the entire value chain of polyethylene terephthalate plastics has led to many unanswered questions and misunderstood impacts on the plastics waste economy. The purpose of the study was to document and depict the value chain and its activities within the polyethylene terephthalate waste economy in South Africa, which, according to the available literature, has not been done before. The documentation of the value chain and its activities will assist in identifying the possibilities of job creation within the waste economy, which could impact the diversion of waste from the landfill.
