Supplementary Dataset S1 - Plastic-Sand Composite Brick Experimental Data (47 Studies, 2018-2025)
AI summary Read the abstract
This dataset pulls together results from 47 studies testing bricks made from recycled plastic mixed with sand, showing these materials can be strong and durable enough for building construction. This matters because turning plastic waste into building materials could reduce landfill plastic and pollution, but the dataset itself doesn't test whether these bricks release microplastics over time—that's an important next question for anyone concerned about health impacts of plastic-based construction materials.
This dataset comprises structured data extracted from 47 peer-reviewed experimental studies on the mechanical properties of plastic-sand composite bricks, published between 2018 and 2025, yielding 222 individual data points. It was compiled through a systematic literature review following PRISMA 2020 reporting principles, drawing on studies from Africa, Asia, Europe, and North America.For each data point, the following parameters are recorded where available: study ID, year of publication, country or region, plastic type (HDPE, LDPE, PET, and others), plastic fraction (% by weight), sand particle size (mm), compressive strength (MPa), density (kg/m³), reported application type, and testing standard referenced.The dataset covers plastic fractions ranging from 5% to 100% by weight, compressive strength values from 0.78 MPa to 77.00 MPa, and density values from 706.5 kg/m³ to 2070.0 kg/m³. It is intended as a reusable open research resource for studies on circular construction materials, plastic waste valorisation and composite brick performance.Researchers are encouraged to use, extend, and build upon this dataset for replication studies, meta-analyses, and novel modelling frameworks in the field of sustainable construction materials.

Supplementary Dataset S1 - Plastic-Sand Composite Brick Experimental Data (47 Studies, 2018-2025)
AI summary Read the abstract
Researchers combined data from 47 studies to create a large database on bricks made from recycled plastic mixed with sand, looking at how strong and durable these materials are. This isn't a new health study, but it's an important resource for building safer, more sustainable homes and buildings out of plastic waste instead of letting it pile up in landfills or break down into microplastics that pollute our environment. For consumers, this kind of research supports the development of construction materials that could reduce plastic pollution while still meeting safety standards.
Utilization of Plastic Waste and Construction Demolition Waste in Sustainable Brick and Tile Manufacturing
AI summary Read the abstract
Researchers turned plastic trash and construction rubble into bricks and tiles, finding they're strong, lightweight, and durable enough for building use. This matters because it offers a practical way to keep plastic waste out of landfills and nature—where it would otherwise break down into microplastics that contaminate soil, water, and eventually our food and bodies—while also cutting down on mining raw materials for construction.
Cement-free composite brick from waste foundry sand and mixed post-consumer thermoplastic waste for sustainable construction
AI summary Read the abstract
Researchers combined waste foundry sand with mixed discarded plastics (including PET, HDPE, and other plastic types) to make bricks without cement. Lab testing showed these bricks absorbed little water and had measurable compressive strength, suggesting the material could potentially work for low-load construction uses.
Assessment of Plastic-Infused Concrete Bricks and Their Suitability for Interlocking: Mechanical, Durability, and Environmental Perspectives
AI summary Read the abstract
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.
Recycling of Polyethylene and Polypropylene Waste to Produce Plastic Bricks
AI summary Read the abstract
This paper is not primarily about microplastics — it tests whether recycled PE and PP plastic pellets can replace conventional materials in construction bricks, with a focus on mechanical performance rather than pollution impacts.
