A carbon footprint assessment of GREENTECH gypsum blocks, conducted incompliance with lS0 14067:2018 and PAS 2050:2011,

revealed that producing oneton emits only 203 kg COz equivalent - a figure significantly lower than that oftraditional concrete 

and cement, at approximately half and one-third of theiremissions, respectively. This reduction is achieved through the use of 

recycledmaterials and energy-efficient production processes. Widely applied in non-load-bearing partition walls, gypsum blocks 

support Hong Kong's sustainability goalsby offering a greener alternative to conventional construction materials.
