EPS and XPS Recycling and Reuse
Industry Analysis and Implementation Strategy
The construction industry faces significant challenges in managing the insulation material waste, expanded polystyrene (EPS) and extruded polystyrene (XPS) due to their low density, contamination issues, and the presence of hazardous flame retardants. This study investigates the feasibility and environmental impact of different end of life methods for EPS and XPS waste contaminated with various construction materials, including glue and mortar as well as bitumen. A practical approach is taken, aiming to tailor existing recycling technologies to the specific needs and constraints of construction practices, thereby increasing the industry’s recycling rate and reducing its environmental footprint.
This work explores the entire lifecycle of EPS and XPS, from production and application to waste generation and recycling, and proposes solutions. By focusing on practical solutions and industry-specific needs, this work facilitates a shift towards a more circular and sustainable model for EPS and XPS waste management in the construction industry, offering actionable recommendations for construction companies and waste managing companies to adopt more environmentally responsible practices. ...

In this project, student teams from Universidad San Francisco de Quito and Delft University of Technology worked together to provide safe drinking water in Ecuador. We used M-100 chlorinators from the company WaterStep, donated by Water Ambassadors Canada, to chlorinate water in schools and communities. The journey involved testing water quality, setting up the chlorination systems, and learning how to work in different communities. The key to success was testing water properly and setting up the system carefully. Learnings about working with local communities and organizations are included as well as the importance to understand each community’s needs to make a real difference.
