Some of our clients

Our Beginnings

To continue the endeavor in localizing the technology of Pneumatic Waste System and development in Recycling Chute Storage System, our founder Mr. Cheong Kong Chuan set up Greenwave Solutions (GWS) in 2009 with this purposeful mission in mind.

Since 2002, Mr. Cheong headed the localization and development of the above technologies in SembEnviro. During his tenure there, he secured government funding for his work in both technologies. The objectives of his distinct pursuits are to develop and refine both systems to suit and meet local urban requirements, as well as to bring the cost of implementation down.

Today, GWS specializes in engineering design, fabrication, installation, and maintenance work for Pneumatic Waste System, Recycling Chute Storage System, and Central Vacuum System focusing on innovative clean and green technologies for urban developments. As the only player in Singapore with integrated capabilities from technology development to fabrication, installation, and maintenance, we are steadily recognized for delivering innovative and cost competitive solutions.
