Lego-like Bricks Manufacturing Using Recycled Polyethylene (PE) and Polyethylene Terephthalate (PET) Waste in Egypt
Researchers tested the use of recycled polyethylene and PET plastic waste as raw materials for manufacturing Lego-like construction bricks in Egypt, addressing plastic waste accumulation and its degradation into microplastics. The recycled bricks showed adequate structural properties, demonstrating a viable pathway for diverting plastic waste from the environment into durable construction materials.
Performance Comparison of Recycled HDPE, PET, and LDPE in Construction Materials: A Systematic Review
This review of existing research found that recycled plastic bottles and containers can be successfully turned into strong building materials like bricks and blocks. The strongest results came from using about 7.5% recycled plastic mixed with traditional materials, creating bricks that meet construction standards while helping reduce plastic waste in landfills. This matters because it offers a way to tackle two big problems at once: getting rid of plastic waste and creating cheaper, sustainable building materials.
Polyethylene Terephthalate Waste Utilisation for Production of Low Thermal Conductivity Cement Sand Bricks
This engineering study tested whether shredded PET plastic waste could partially replace sand in cement bricks, finding it reduced the bricks' thermal conductivity while maintaining acceptable strength. Incorporating plastic waste into construction materials could divert it from landfills while reducing building energy costs. This paper focuses on construction materials and is not directly related to microplastic health risks.
