Re:New project introduces an innovative approach to repurposing construction demolition waste (CDW), particularly concrete and brick, by leveraging robotic ramming and advanced material processing techniques. The objective is to develop durable, modular architectural components that minimize environmental impact and promote resource efficiency.
The construction and demolition (C&D) sectors are among the most significant contributors to global waste, carbon emissions, and environmental degradation; creating immense challenges for the sustianable development.
The project integrates data-driven demolition mapping to optimize material reuse and reduce waste generation. Advanced object detection systems powered by machine learning for accurate material identification, enables strategic demolition planning. By analyzing buildings to map material quantities and types, this methodology facilitates systematic dismantling processes, challenges the current practices and extends the life cycle of materials.

The fabrication process draws inspiration from vernacular rammed earth technique. Recycled concrete and brick are processed into fine particles through refining and waste separation. Two compositional mixes—one for non-load-bearing elements and another for load-bearing components—are developed to cater to various architectural requirements and applications. These mixtures are optimized for strength, durability, and modularity while reducing environmental footprints.
A custom end-effector that combines pneumatic ramming, selective material deposition, and leveling for consistent layering and compaction is designed and integrated. This automated approach enhances efficiency, reduces labor demands, and enables large-scale production. Functionally graded materials can be achieved by varying material composition to optimize for structural stability. These elements can be fabricated on-site or transported from off-site facilities, offering adaptability based on project requirements.
