Valorization of construction and demolition waste as reinforcing nanofiller for polymer composites.
Article in Discover nano, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
Plastics represents one of the largest global waste streams, with recycling limited by their heterogeneous composition and degraded properties. Simultaneously, construction and demolition activities generate significant amounts of fine fraction waste without reasonable utilization objectives. This study investigated the potential of combining heterogeneous plastic waste and construction and demolition waste (CDW) powder into high-value nanocomposites at various filler loadings (1, 2.5, and 5 wt%), aiming to enhance the mechanical performance of recycled plastics. Virgin polypropylene matrix and commercial nanoclay were used as reference materials. The CDW powder exhibited comparable overall performance to commercial nanoclay in elastic modulus (+ 12%) and even outperformed it in terms of tensile strength (+ 3% vs. +0.4%). Statistical analysis using two-way ANOVA (n = 12, α = 0.05) confirmed that both filler type and loading level significantly affected tensile strength of composites (p < 0.0001), while elastic modulus was primarily influenced by the filler loading. Furthermore, a theoretical model predicting interfacial adhesin between polymer matrix and reinforcing fillers supported these results, indicating stronger polymer-particle adhesion with CDW particles compared to nanoclay. These findings demonstrate that nanoreinforcement is an effective strategy to valorize recycled plastics by improving their mechanical performance and establish CDW-origin filler as a competitive alternative to conventional virgin fillers in the polymer industry.
