IVRY II – WASTE-TO-ENERGY PLANT BOTTOM ASH TUBE AND CAGE SCREENING PROJECT

Completed Project Reference – KDT Industry

Introduction: Advanced Screening Solutions for Waste-to-Energy Efficiency

The Ivry II Waste-to-Energy (WtE) Plant Bottom Ash Tube and Cage Screening Project demonstrates how KDT Industry provides innovative ash handling and screening technologies to maximize the efficiency and sustainability of modern waste-to-energy facilities. Bottom ash screening ensures that metals, aggregates, and usable by-products are separated from residual waste, enhancing both resource recovery and environmental performance.

KDT Industry played a central role in this project by designing and fabricating tube and cage screening systems, structural steel supports, silos, and auxiliary handling equipment, enabling Ivry II to meet world-class operational and sustainability standards.
