Recycling of Polyethylene Waste to Produce Plastic Cement
Open accessAbstract
Disposal of plastic waste in environment is considered to be a big problem due to its very low biodegradability and presence in large quantities. Therefore, finding alternative methods of disposing waste by using friendly methods are becoming a major research issue. In this research, high density polyethylene waste is mixed with Portland cement to investigate the possibility to produce plastic cement, and study the effect of replacing sand by fine polyethylene waste with different percentage on the properties of product. The experiments were done by using the waste of polyethylene packages include bottle and food crates in the range of 10% to 80% by volume as a short reinforcement structure. The results show that there is a possibility to produce plastic cement from polyethylene waste and Portland cement by using 60% and 40%, respectively. In addition, their density was decreased, ductility increased, and the workability improved, which lead to produce lightweight materials.

Utilizing plastic waste resulted in lightweight materials by reducing density, increasing ductility, and improving workability.
“In addition, it was shown that utilizing plastic waste resulted in lightweight materials by reducing density, increasing ductility, and improving workability [124].”
From Transforming Plastic Waste into Value: A Review of Management Strategies and Innovative Applications in Sustainable Construction (2025) · cites this paper as [124]
The Compressive strength section reports a 15% density reduction relative to traditional concrete and describes the plastic cement as flexible rather than brittle. The Workability and Compressive strength sections report good workability at certain polyethylene proportions, but do not establish an overall improvement over conventional cement; workability weakened outside the preferred range. (LLM, conf=0.84)
Experimental — accuracy not yet measuredPlastic waste binder and aggregates have stronger binding compared to cement binder.
“Compared to the bond formed by the cement binder, it appears that the plastic waste binder and aggregates have a stronger binding.”

The Production Procedure (section 2.2; page unavailable) describes mixing polyethylene waste with Portland cement, and the Compressive Strength section (3.5; page unavailable) reports strength for those mixtures. Neither section compares the bond between a plastic-waste binder and aggregates with a bond formed by a cement binder; searches for binding, bond, and adhesion found no such comparison. (LLM, conf=0.75)
Experimental — accuracy not yet measuredThis might be attributed to stronger adhesive bond between plastic waste surface area and nearby aggregate particles.
“This might be attributed to the stronger adhesive bond between the plastic waste’s surface area and the nearby aggregate particles [124].”
From Transforming Plastic Waste into Value: A Review of Management Strategies and Innovative Applications in Sustainable Construction (2025) · cites this paper as [124]
The Introduction describes using plastic waste in concrete, and §3.5 reports compressive-strength results, but neither attributes those results to adhesion between plastic surfaces and nearby aggregate particles. Searches for the quoted adhesive-bond explanation and for interfacial bonding found no passage addressing that mechanism. (LLM, conf=0.77)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
