Eco-friendly Products & Raw Materials

Eco-friendly Products

Intensive R&D has led to the innovation of specialised concrete products that are high-performing and at the same time, more sustainable. These include:

Eco & Green Concrete
Our range of Eco & Green Concrete combines the environmentally-friendly features of GGBS, RCA and WCS into one key product. The CO2 savings are substantial. For example, one cubic metre of grade 40 Green Concrete helps to conserve 380 kg of natural granite and reduces carbon emissions by 221 kg, as compared to regular concrete.

Self-compacting Concrete (SCC)
Self-Compacting Concrete (SCC) is another value-added product developed by PanU for its customers. It is typically used to construct building foundations and floor work. It is faster to apply, more fluid and eliminates the use of manual compactors, which helps to lower overall man hours and manpower costs by some 60%.

Recycled Raw Materials

PanU uses recycled raw material as substitutes for natural resources. They include:

  • Recycled Concrete Aggregates (RCA)

    We crush or reuse demolished concrete or hardened returned concrete from projects we supply to. This source saves up to 30% of natural sand and stone required for regular concrete production.

  • Washed Copper Slag (WCS)

    WCS refers to the waste generated from the process of ship washing. It can be used to replace up to 10% of fine aggregates used in producing structural concrete, reducing the overall consumption of natural sand.

  • Ground Granulated Blast Furnace Slag (GGBFS)

    The eco-substitute for Ordinary Portland Cement (OPC), GGBFS is created by the quenching of molten iron slag (a by-product of iron and steel-making) with water in a blast furnace. This produces a glassy, granular product that is subsequently grounded into powder to replace cement.

    A tonne of GGBFS produces only 70 kg of carbon without consuming any natural resources. This compares with a tonne of OPC which produces 970 kg of carbon and consumes 800 kg of limestone and 200 kg of clay.

  • Silica Fume 

    This is a by-product of the electronics industry, for example in the production of silicon wafers, that is recycled as a raw material substitute for cement.

Above are examples of recycled raw materials.


PanU will integrate upstream into the production of cementitious (recycled) materials when its first ground granulated blast furnace slag (GGBFS) grinding plant is completed in Johor, Malaysia, in 2017.
