Pan-United develops low-carbon concrete in Singapore — Channel NewsAsia

In Singapore, Pan-United is developing low-carbon concrete production technologies and digital supply management systems. During the pouring of the foundation slab for The Skywaters building, the company delivered one truckload of concrete every two minutes for 35 hours continuously, Channel NewsAsia reports.

For this project, the company used, among other materials, its proprietary PanU Super Hi-Strength concrete. Pan-United says that using such specialized mixes makes it possible to reduce the required volume of concrete and the carbon footprint of the foundation.

Materials and digital management

The company began research into reducing cement use in 2001 and started digitizing its operations in 2014. Concrete remains suitable for placement for about two hours, so the delivery of thousands of batches with different characteristics must be precisely coordinated.

For this purpose, Pan-United developed the AiR Digital platform. It was initially used for internal operations, and the system was later offered to clients in Asia's concrete and logistics sectors. From its command center, the company uses it to manage the logistics of more than 4,000 daily deliveries.

Emission reduction technologies

According to an estimate cited in the report, about 30 billion tonnes of concrete are used worldwide each year. Cement accounts for about 15% of a typical concrete mix, but its production is associated with 7–8% of global carbon dioxide emissions.

Pan-United says its PanU CMC+ concrete uses carbon capture and utilization technology: CO₂ is mineralized inside the concrete. According to the company, this reduces cement use and increases the material's strength. The technology is used in projects at Tuas Port, the Cross Island Line, Changi Airport Terminal 5, and The Skywaters.

The company has also developed PanU Hi-Albedo concrete for roads, pedestrian paths, and bicycle lanes. It is designed to reduce surface temperatures and mitigate the urban heat island effect. In 2022, Pan-United became the first concrete company in Asia to offer on-demand environmental product declarations with independently verified data for material selection and sustainability reporting.
