Solid Waste Management (SWM) is a significant challenge for the Seychelles because landfilling, the currently employed waste management strategy, poses direct threats to the island nation’s specific weaknesses, through greenhouse gas production, consumption of scarce land, and leachate release to the nearby environment. However, due to the small scale of the Seychelles economy, there is little capital available to stimulate innovations in SWM. The focus of this case study was to understand the current SWM system in the Seychelles and to gain insights into the obstacles and opportunities related to waste reduction.

Research questions

The focus of the case study was to understand SWM in the Seychelles and to provide insights into waste reduction. To guide the study, the following overarching research questions have been proposed:

  1. How does the current system operate? What are ecological risks and waste management challenges?
  2. What are potential waste reduction strategies for stakeholders such as the government, consumers, and waste managers? What are obstacles preventing their implementation?
  3. How could the future of waste management look like?

Collaboration between TdLab and partners in the Seychelles

The case study consisted of 18 ETH master’s students with diverse scientific backgrounds and 18 bachelor’s students at the University of Seychelles (UniSey). Research was conducted over six months, including a three-week field phase in the Seychelles. Researchers and teachers from ETH and UniSey guided students throughout the case study, which was supplemented by additional support from an advisory board of local experts. Students intensively engaged with a variety of stakeholders from government, administration, business, NGOs, and civil society. The Seychelles’ Ministry of Environment, Energy & Climate Change was major partner in this collaboration.
