This thesis addresses the issue of bulky waste management in Rotterdam. The processing methods are underdeveloped, and inefficiencies in the current collection system result in valuable materials being frequently incinerated. The city strives to achieve its circularity goals: to prevent waste, improve separation, and ensure high-quality processing. This thesis presents a circular service system that integrates citizen behaviour, innovative waste management, and stakeholder engagement to give bulky waste a second life and save valuable products and materials from incineration.

The research used the principles of Effectuation to create opportunity spaces within the scope. With the use of participatory design methods the collaboration with citizens and municipal employees was ensured. This was needed for emphasizing practical engagement and real-world solutions. This thesis is structured by integrating Effectuation with the New Product Development process. This entrepreneurial thinking approach and iterative design explored possibilities for adaptive problem solving.

RepurposeRide is the final design. It is a transportation network using cargo bikes to redirect bulky waste within neighborhoods, giving items a second life through reuse at Wijkhubs and giveaway stores. Materials of lower status are delivered to environmental parks for high-quality processing. This system prevents waste from being crushed in compactor trucks, contributing to waste prevention, improved separation, and high-quality processing.
It demonstrates a citizen-centered, circular bulky waste collection service for Rotterdam’s waste management. Circularity, convenience and community engagement are the foundations to support reuse, enhance material recovery and prevent waste. While limitations remain, the project provides a basis for further development. RepurposeRide strives to combine environmental responsibility with social impact, establishing an identity rooted in sustainable entrepreneurship.
