Sustainable Sourcing and Compositional Advantages
Oil Palm Mesocarp Fibre (OPMF) stands out as a highly sustainable additive due to its abundance as an agro-industrial byproduct, its renewability, and its favorable lignocellulosic composition. Comprising 40.2% cellulose, 9.8% hemicellulose, and 13% lignin, OPMF offers a natural, lightweight alternative to conventional additives. Its utilization directly addresses critical waste management issues in palm oil-producing regions, aligning with UN Sustainable Development Goals by promoting a circular economy and reducing reliance on synthetic polymers.
Modulating Physical and Mechanical Properties
The incorporation of OPMF significantly influences brick properties. While 10% OPMF led to a compressive strength reduction from 24.6 MPa to 4.1 MPa, this level remains suitable for non-load-bearing applications. Furthermore, OPMF addition increased porosity (13% to 25%) and firing shrinkage (0.3% to 2.5%), which requires careful optimization but contributes to a lighter product. Lower OPMF concentrations (e.g., 5%) maintain acceptable mechanical integrity for many applications.
Enhanced Thermal Insulation for Energy Efficiency
A key advantage of OPMF incorporation is the significant improvement in thermal performance. Bricks with 10% OPMF showed a thermal conductivity of 0.34 W/m.K, a substantial reduction from the control's 0.54 W/m.K. This enhancement is directly linked to the increased porosity created by the thermal decomposition of OPMF's organic matter during firing, making OPMF-modified bricks an excellent choice for improving building energy efficiency and thermal comfort.
Ensuring Environmental Safety: Heavy Metal Immobilization
Leaching tests (TCLP and SPLP) confirmed that critical heavy metals, including lead (Pb), chromium (Cr), and zinc (Zn), were successfully immobilized within the OPMF-modified bricks. All tested bricks, including those with 5% OPMF, complied with USEPA and WHO guidelines, demonstrating that the firing process effectively encapsulates these elements, forming stable mineral phases and minimizing environmental risks associated with waste valorization.

Product Characterization & Analysis
| Feature | OPMF-Modified Bricks | Conventional Clay Bricks |
|---|---|---|
| Compressive Strength | Reduced to 4.1 MPa (at 10% OPMF), suitable for non-load-bearing walls. | High strength, typically >14 MPa for load-bearing applications (24.6 MPa for control). |
| Thermal Insulation | Enhanced (0.34 W/m.K at 10% OPMF), ideal for energy efficiency. | Lower thermal performance (0.54 W/m.K for control). |
| Heavy Metal Immobilization | Excellent compliance with USEPA & WHO guidelines, immobilizing Pb, Cr, Zn. | Raw materials may contain elevated heavy metals (e.g., Pb 0.586 ppm, Cr 0.690 ppm). |
| Water Absorption | Elevated (up to 20%), requiring consideration for external use. | Lower (3% for control), generally suitable for diverse applications. |
| Density | Significantly reduced (1563 kg/m³ at 10% OPMF), leading to lighter construction. | Higher density (1799 kg/m³ for control), common in standard construction. |
Environmental Stewardship: Zero-Waste & Immobilization Success
The research demonstrates OPMF's dual impact: converting an agricultural waste into a valuable building material and actively mitigating environmental risks. By immobilizing heavy metals like Lead, Chromium, and Zinc within the brick matrix, the process ensures compliance with international safety standards (USEPA and WHO), preventing groundwater contamination and promoting a truly circular economy in construction. This valorization strategy reduces landfill burden and enhances resource efficiency.
