Keppel China and Aqua 3I: Levelling up sustainable solutions Abroad
THE PARTNERSHIP
In 2023, Singapore enterprise Keppel’s subsidiary in China was on the lookout for partners to help with its sustainability push for managed properties, especially in the areas of energy conservation and indoor air-quality management.
They were introduced by Enterprise Singapore to Singapore-based R&D company, Aqua3I. The two companies teamed up and received funding under the PACT scheme (see boxed content “More about the PACT Scheme” above for more details).
The two companies first collaborated on the Sino-Singapore Tianjin Eco-City project which saw Keppel China introduce Aqua3I’s patented antimicrobial coated patches to cassette air-conditioners in indoor office spaces to reduce air pollution. These patches work by emitting negative oxygen ions that bind to pollutants. This increases the mass of pollutants and accelerates their removal from the air.
Separately, Aqua3I’s solution was also applied to reduce formaldehyde levels indoors to 0.06mg/m3, which is lower than the acceptable threshold for such spaces; around 0.08mg/m3.
With the solution, there was no need for Keppel to adopt the usual airing or “off-gassing” process, that typically takes months. “Off-gassing” is a process where items which contain formaldehyde such as pressed-wood furniture, carpets, and certain fabrics, are subjected to cross-ventilation — a process where airflow is enhanced using exhaust fans while leaving windows and doors open to expel air pollutants more effectively.
Following the successful implementation in Tianjin Ecocity, Keppel also plans to expand the application of Aqua3I’s innovations to customers in other Chinese cities, such as the Jinan Startup Area (JSA) in Shandong. The JSA, which has been operational since 2021, is a commercial area housing companies operating in emerging industries such as clean energy, smart manufacturing, and more.
