In line with the Government initiative towards targeting Zero Landfill, HCH initiated a research project to develop precast concrete products using recycled aggregates recovered from construction waste.

Prof. Tay Joo Hwa and Prof. Ting Seng Kiong of Nanyang Technological University, Singapore were engaged to determine the optimum design mix for various concrete grades meeting different criteria in accordance with SS214:1999. To date, HCH has produced quality products using a computerized control batching plant.
