Pneumatic Waste Conveyance System PWCS is one of the HDB Greenprint project to create a sustainable yet promote an environmental living space for our public housing. It has been a full swing for PWCS to be implemented to the newer BTO projects. 

Most projects will share the same ODI bunker room whereby it centralised the system to all say 2-5 contracts. This too, arise questions on the waste management if there's mishap or malfunction to the bunker. Thus, it is crucial for our M&E team to re-look and prevent such cases to happen. However, this is a great step for HDB to actually move forward. And with this innovation, I too hope for our nation to go green.
