In a groundbreaking study published in ‘Vojnotehnički Glasnik’, researchers have unveiled a cost-effective solution to tackle housing challenges in developing countries while simultaneously addressing the global plastic waste crisis. Led by Abdelkader Daikh from the University of Mustapha Stambouli in Algeria, the research introduces a manual plastic brick extruder designed to produce composite bricks from recycled polypropylene and brick powder.
The innovative extruder, featuring a 60 mm die and a manual crank, aims to empower local communities by providing an affordable method for brick production. “Our goal was to create a sustainable and practical solution that not only meets housing needs but also promotes environmental responsibility,” Daikh explained. The extruder’s design includes a heating system and a hopper, enabling the production of uniform composite specimens using varying ratios of polypropylene and brick powder.
Mechanical testing of the bricks revealed promising results. The optimal polypropylene to brick powder mixture was found to be 40:60, achieving impressive compressive strength values between 23.76 and 24.90 MPa. For flexural strength, a 50:50 ratio yielded peak performance, highlighting the potential for these composite materials to meet construction demands. “The findings indicate that we can produce high-quality bricks from waste materials, providing a dual benefit of sustainable building and waste management,” Daikh noted.
The implications of this research extend beyond just material science. By utilizing locally available waste materials, communities can significantly reduce construction costs, making housing more accessible. Furthermore, the extruder’s manual operation allows for low-tech, decentralized production, fostering local entrepreneurship and job creation. As Daikh emphasized, “This approach can transform the way we think about construction in resource-limited settings.”
Looking ahead, the study paves the way for future developments in sustainable construction. The next steps involve optimizing the extrusion process and exploring the use of additional waste materials, which could further enhance the properties of the composite bricks. Long-term durability studies are also on the horizon, ensuring that these bricks can withstand the test of time in various environmental conditions.
This research not only offers a practical solution for affordable housing but also sets a precedent for how the construction sector can leverage waste materials for innovative building solutions. As the demand for sustainable practices grows, the findings from Daikh’s team could inspire a new wave of eco-conscious construction techniques, ultimately reshaping the industry.
