ClearAssessment of Plastic-Infused Concrete Bricks and Their Suitability for Interlocking: Mechanical, Durability, and Environmental Perspectives
Researchers tested plastic-infused concrete bricks as a way to repurpose plastic waste in construction materials, evaluating their mechanical strength and suitability for different building applications. The study explores whether incorporating plastic waste into durable materials can reduce the plastic entering the environment as microplastics.
Evaluating the structural performance of waste PET-infused interlocking units versus traditional stone masonry
This study is not directly about microplastics — it evaluates the compressive strength and water absorption of interlocking bricks made from waste PET plastic as a partial cement replacement in construction.
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.
Utilization of Plastic Waste for Developing Composite Bricks and Enhancing Mechanical Properties: A Review on Challenges and Opportunities
This review of research on plastic waste composite bricks found that PET has the highest recycling efficiency among plastics used for brick production and highlights the need for standardized specifications, contamination assessments, and policy frameworks to promote wider adoption.
Experimental Tests on Lightweight Cement Mortar and Concrete with Recycled Plastic Wastes
This paper is not relevant to microplastics research — it tests the mechanical properties of cement mortar and concrete incorporating recycled plastic waste granules as aggregate substitutes, a construction materials engineering study.
Recycling/reuse of plastic waste as construction material for sustainable development: a review
Researchers reviewed how waste plastic can be incorporated into construction materials — as binders, aggregates, or cement substitutes in bricks, tiles, concrete, and roads — finding that plastic-modified materials often show competitive strength properties while simultaneously diverting plastic waste from landfills.
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.
Potential use of PET and PP as partial replacement of sand in structural concrete
Researchers tested whether PET and polypropylene plastic waste could partially replace sand in structural concrete, evaluating the physical and mechanical properties of the resulting material. Using post-consumer plastic in construction is one strategy for diverting plastic from the waste stream and preventing it from breaking down into environmental microplastics.
Circular economy model for reuse of plastic in eco-efficient production of building materials
This study explored using plastic waste in the production of construction blocks and bricks as part of a circular economy approach, reducing the amount of plastic that enters the environment as microplastics. The construction sector offers a significant opportunity to valorize plastic waste as a durable material rather than allowing it to degrade in landfills.
Research on Properties of Ecobricks and its Possible Applications
This study examined the properties of ecobricks — plastic bottles stuffed with non-recyclable waste — as a building material, finding they can partially substitute for conventional bricks while diverting plastic waste from landfills.
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.
Sustainable geopolymers from polyethylene terephthalate waste and industrial by-products: a comprehensive characterisation and performance predictions
Researchers developed geopolymer bricks using recycled PET plastic waste combined with industrial by-products like rice husk ash and blast furnace slag. They found that certain formulations produced bricks with strength and durability comparable to conventional building materials. The study demonstrates a practical approach for diverting plastic waste from landfills while creating sustainable construction materials.
Recycling Waste Plastics into Plastic-Bonded Sand Interlocking Blocks for Wall Construction in Developing Countries
Researchers investigated the use of waste polyethylene mixed with sand to produce plastic-bonded interlocking blocks for wall construction in developing countries, reporting on production methods, mechanical properties including compressive strengths of approximately 15 MPa, and failure mechanisms of three block wall system designs. The plastic-bonded blocks outperformed conventional sandcrete blocks, demonstrating a viable pathway for recycling waste plastics into construction materials.
