A Narrative Behind the Study
Termites have long intrigued scientists and builders alike due to their remarkable ability to construct resilient structures using natural resources. Their mounds, often deeply rooted in the soil, display a unique cohesion and strength that is difficult to replicate. As human activity continues to encroach on these ecosystems, termite mounds are frequently abandoned. Our study taps into the potential of this Termite Mound Soil (TMS), a material rich in kaolinitic clay, for sustainable ceramic composite development.
Meanwhile, plastic bottles and sawdust, by-products of our modern consumption and wood industries, remain significant environmental pollutants. Sawdust is commonly burned, releasing greenhouse gases, and PET plastics persist in ecosystems for decades. This study proposes a circular engineering approach, where these wastes are valorized as reinforcements in ceramic composites, rather than discarded or incinerated.
Key Insights
✅ PET-TMS composites showed higher porosity (up to 43%), reduced density, and lower compressive strength, but are ideal for lightweight, insulating, and non-load-bearing applications.
✅ Sawdust-TMS composites had moderate porosity (up to 33%) and higher compressive strength, making them suitable for moderate-load structural applications.
✅ The kaolinitic nature and binding capacity of TMS enhanced composite cohesion, while sawdust ash contributed fluxing oxides that improved densification.
Policy and Practice Recommendations
📌 Promote eco-friendly construction by incentivizing the use of waste-based ceramic composites in public and low-income housing projects.
📌 Integrate waste valorization standards into national and municipal waste management policies.
📌 Encourage research-industry collaboration for developing scalable production models using termite mound soil and agro-waste.
📌 Support legislation banning open burning of sawdust and plastics, offering R&D-driven alternatives like this.
