Circular Economy & Recycling Technologies

Trinity College Dublin

Circular Economy & Recycling Technologies

The Circular Economy concept offers strong alternative solutions to these problems. The main goal of this approach is to keep products, components, and materials at their highest levels of use and value by closing the loop of product life cycles. This approach requires allowing economic activity to grow while minimizing the use of finite resources and waste generation.

The circular model is based on three principles:
• Designing out waste and pollution
• Keeping products and materials in use
• Regenerating natural systems

This course will provide students with core knowledge of the Circular Economy concept as well as the relevant technologies used in the recycling area. Through a blended delivery of modules, this programme will explore topics such as life cycle assessment (LCA), waste management, waste rock reclamation, waters, and sludge treatment as well as recycling, reprocessing, and remanufacturing. It will allow students to develop a unique perspective of the design process to enable the recovery and reuse of materials.
