Application deadline

Applications accepted all year round

Applications are invited for a self-funded, 3 year full-time or 6 year part-time PhD project.

The PhD will be based in the Accounting and Financial Management Subject Group and will be supervised by Dr Roza Sagitova and Professor Diego Vazquez-Brust. 

The work on this project will:

  • Conduct a comprehensive and systematic literature review on business practices in plastic sustainability
  • Develop a framework to assess interventions needed to steer pro-circular change (implementation of ‘enzyme friendly plastic’ technology) in industry, considering the impact of that change on disadvantaged groups
  • Engage in Sustainability and the Environment research theme at the 1024˹. 

Plastic waste is one urgent environmental challenge. The planet is drowning in plastic pollution, with more than 8.3 billion tons of plastic produced from 1950s (UNEP, 2021). There are a number of different measures across the globe to tackle plastic issues, however, those measures are fragmented. As a result, the approach across industries to plastic sustainability also vary dramatically. UNEP (2021) notes that business do not efficiently manage their plastic waste. Only 9% of plastic waste is recycled, with even lower figures for commercial plastic waste (Circle Economy, 2021). There is resistance in business to substantially change the practice towards circular and sustainable plastic, as the business rhetoric is focusing more on individuals’ responsibility and incremental improvements in recycling, often in the way of “recyclable” products that are not actually recycled but incinerated or sent to landfill (Frei and Vazquez-Brust, 2020). State of the art technology offers mechanical and chemical methods for plastic recycling but these are too close to linear models and lack the necessary radical intent to step up circularity (Khan et al., 2020). Most of the plastics with recycled content cannot be recycled multiple times because of the quality of polymers resulting from existing recycling technologies. Recent research on ‘super-enzymes’ provides promising solutions to tackling plastic pollution and opportunities to accelerate the transition to circular and sustainable plastic (Singh et al., 2021).

However, the implementation and scaling of these technologies that can revolutionize the management of plastics would require radical changes: in the design of plastic materials, products, logistics solutions and business models. Some of these changes may unintentionally drive social exclusion and injustice, for instance eliminating jobs for low skilled sectors. More research is needed to determine the timescale and type of interventions needed to steer pro-circular change, and we particularly lack understanding of how (if) circular plastic practices can contribute to empower disadvantaged groups. Aiming to address such gap, this PhD project will explore current plastic sustainability practices and obtain a better understanding of the incentives and barriers for the implementation of radical technologies enabling circular and sustainable plastic systems in a close-loop plastic lifecycle that would effectively make companies accountable for their plastic footprint. We are interested in exploring this question investigating how the new technology of ‘enzyme friendly plastic’ can be scaled up to business level in a manner that is sustainable, circular and socially inclusive.
