What are examples of market networks

Fishing for Litter - A Market-Actor-Network Perspective on Marine Plastic Waste Management

info

The PhD project focuses on the dynamics of the market development of secondary raw materials using the example of the use of marine plastic waste by examining the evolution of the recycling routes from a market actor network perspective.
Today, around 330 million tons of plastic are produced worldwide each year, of which 5 to 13 million tons end up in the oceans as waste. If the current trends continue, a doubling of the plastic waste in the sea is predicted over the next twenty years, which would massively increase the already enormous environmental impact. The dissertation project argues that the markets for the various possible recycling paths for marine plastic waste - material recycling, energy recovery, reuse and landfill - play a key role in solutions for dealing with plastic waste in the oceans. In the sense of economic sociology or evolutionary economy, markets are interpreted as systems of social actors that are connected to networks through their market exchange relationships. The aim of the research project is to reconstruct dynamics in the development of the markets for the recycling of marine plastic waste in order to further develop the theoretical and conceptual foundations of a cycle-based economy and, based on this, to derive statements for the political design of the framework conditions of the markets for plastic waste from the oceans can. The research work focuses on European market networks for plastic waste from the Northeast Atlantic, including the North Sea. The Market-Actor-Network perspective on the handling of marine plastic waste includes not only economic actors, such as companies and businesses, but also political and civil society actors, whereby the existing approaches of economic sociology and evolutionary economics are complemented with a governance perspective. The empirical analysis is carried out using a case study approach, based on existing initiatives for the recovery of marine plastic waste in Europe, based on secondary materials and interviews. The research work aims to contribute to the solution of one of the greatest current environmental challenges with its results.
