Current Municipal Solid Waste Management in a Large City and Evaluation of Alternative Management Scenarios

Sustainable waste management is a fundamental aspect in a circular economy. The focus of this work is to evaluate the performance of the current MSW management system in the city of Oslo, and to understand how to possibly close the gap between today's recycling rate and the EU sorting and recycling targets for 2025 and 2030. The adoption of innovative solutions such as central sorting and chemical recycling of plastic might help achieving a higher overall recycling rate. While the achievement of a higher source sorting can help achieving the EU recycling targets without undergoing large investments, it might be challenging to find measures and incentives that succeed in reaching the desired citizen involvement. The work focuses on the waste fractions for which specific targets are set by the EU, i.e., biowaste, plastic, paper and cardboard, glass and metal. This study can help waste management companies to understand how the introduction of different technologies within their waste management system might help achieving the EU recycling targets, and help policymakers understand the fundamental role of citizen involvement and source sorting.
