Do you trust that new construction materials based on organic fibres can safely support coastal infrastructure?
Russian and Chinese researchers have developed a sustainable technology that significantly increases the strength of calcareous sand. The material, which avoids high-temperature firing, utilizes a blend of enzymes, coconut fibre, and calcium carbonate to stabilize soil for industrial use.
Why it matters
This innovation provides a low-carbon alternative for infrastructure development by utilizing local materials. It offers a cleaner solution for reinforcing ground in sensitive or remote construction zones.
The optimized mixture incorporates equal parts fine and coarse sand combined with 0.4 percent coconut fibre for reinforcement. This chemical process eliminates the need for energy-intensive, high-temperature firing.
The players
South Ural State University
This Russian institution focuses on interdisciplinary engineering and materials science research.
Zhejiang University
Located in China, this university is a leading center for advanced technological and environmental studies.
The details
Calcium carbonate acts as a binding agent for sand grains, while the coconut fibre provides structural integrity to prevent degradation during impact. The method is designed to be suitable for reinforcing the ground beneath jetties, breakwaters, and airport runways.

The Big Picture
This development challenges the reliance on traditional kiln-firing processes for construction material stabilization. By proving that organic binding agents can achieve superior structural results, it paves the way for a paradigm shift toward low-carbon geotechnical engineering.
This technology could lower the environmental footprint of future coastal and aviation infrastructure projects. Over time, it may lead to more cost-effective and sustainable building materials for large-scale civil engineering works.
The takeaway
The use of coconut fibre and enzymes demonstrates that industrial-grade soil reinforcement does not always require high-energy heat treatments. This approach highlights the potential for using natural additives to replace resource-heavy methods in modern construction.
