Discussion on “Potential improvement in the mechanical performance and thermal resistance of geopolymer with appropriate microplastic incorporation: A sustainable solution for recycling and reusing microplastics”
This discussion letter responds to a paper by Xie et al. (2024) on incorporating microplastics into geopolymer matrices as a recycling strategy, noting that the approach of encapsulating MPs of 50–500 µm in fly ash/slag-based geopolymers improved mechanical and thermal properties. The authors expand on the findings and discuss implications for sustainable MP waste management through construction material incorporation.
Assessment of Plastic-Infused Concrete Bricks and Their Suitability for Interlocking: Mechanical, Durability, and Environmental Perspectives

The study explores whether incorporating plastic waste into durable materials can reduce the plastic entering the environment as microplastics.
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.

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.
Hydrothermal zeolitization: Towards a paradigm shift for producing stronger and more sustainable construction materials
Researchers combined a water-based mineral hardening process (zeolitization) with kaolin ceramics fired at lower-than-usual temperatures, using microplastic waste as pore-forming additives, and found this method increased mechanical strength up to 37-fold compared to untreated materials. The approach offers a way to repurpose plastic waste in construction materials while reducing the energy costs of ceramic manufacturing.
The Impact of Recycled Polyethylene Terephthalate as Aggregate Replacement on Mechanical and Ecotoxicological Properties of Mortar
Researchers tested mortar made with recycled PET plastic replacing some of the natural aggregate and found that it maintained comparable compressive strength while passing ecotoxicity tests with plants. The study suggests that incorporating recycled plastic waste into construction materials could be a viable way to reduce plastic in landfills without creating significant environmental harm.
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.
Turning the tide on microplastic pollution: Leveraging the potential of geopolymers for mitigation
This review examines the potential of geopolymers, sustainable materials made from industrial waste, as tools for removing microplastics from contaminated water. Researchers found that geopolymers offer advantages including high porosity, chemical stability, and tunable surface properties that make them effective at capturing microplastic particles. The study suggests that geopolymer-based approaches could provide a scalable and environmentally friendly alternative to conventional microplastic remediation methods.

This review evaluates the use of plastic waste as a substitute material in concrete, analyzing its effects on mechanical strength, durability, and microstructure to assess its viability as a sustainable construction approach.
Recycled Surgical Mask Waste as a Resource Material in Sustainable Geopolymer Bricks
This study is not directly about microplastics — it investigates incorporating shredded single-use surgical mask waste (largely polypropylene) into geopolymer bricks as a construction material, finding improved strength and reduced shrinkage. While tangentially related to plastic waste management, it does not address microplastic pollution or health risks.
Investigating the Use of Post-Consumer LDPE Waste and Stone Dust in Sustainable Concrete Composites
Researchers incorporated post-consumer LDPE plastic waste and stone dust into concrete mixes and found that these additions can maintain acceptable mechanical properties. Reusing plastic waste in construction materials diverts plastics from landfills and reduces their potential to fragment into environmental microplastics.

A sustainable approach to geopolymer concrete utilizing waste materials including plastic waste
This review examined the use of various supplementary cementitious materials including fly ash, silica fume, rice husk ash, and plastic waste in geopolymer concrete as a lower-carbon alternative to Portland cement.

Performance of recycled Bakelite plastic waste as eco-friendly aggregate in the concrete beams
Researchers tested concrete mixtures containing recycled Bakelite plastic waste as a partial substitute for stone aggregate, finding that adding up to 10% Bakelite generally reduced strength but prevented sudden cracking during failure. While this offers a way to divert hard-to-recycle plastic from landfills — where it would otherwise slowly break down into microplastics — the strength trade-offs must be carefully managed in structural applications.
