“…In the past 75 years, plastic has increasingly replaced natural materials in various fields and has become an essential part of everyday life (Elahi et al, 2021). Plastic waste can break into smaller fragments through various mechanisms such as wave action, hydrolysis, and photodegradation when entering the atmosphere, which can be classified as macroplastics (>5 mm), microplastics, (0.1 µm to 5 mm) and nanoplastics (< 0.1 µm) (Gilani et al, 2023;Rochman & Hoellein, 2020;Veerasingam et al, 2021). Agricultural lands receive 14% of all plastics discharged into the environment.…”

Although plastics provide numerous conveniences for human life, concerns about ecosystems and human life are rising tremendously due to increased plastic production and consumption. The ubiquitous presence and undeniable distribution of microplastics (MPs) in agricultural usage created a major risk concern for soil ecology and human health. The ecological risk assessment of microplastics in agricultural sites in the Coimbatore region of South India has been evaluated using three ecological risk indices: Pollution Hazard Index (PHI), Pollution Load Index (PLI), and Potential Ecological Risk Index (PERI). Based on the concentration of hazardous MPs (Polyethylene, polystyrene, polyacrylonitrile, polyacrylamide, polyacrylamide, polypropylene, polyvinyl chloride) in sampling sites, risk assessment indicated the major risk level in inorganic fertilizers applied site. Meanwhile, PLI indicated that all the sites were in category I with low pollution load in the region. However, the hazard scores of polymers increased the PERI values and exhibited their values in the extremely dangerous category. Since the models for evaluating MPs risk in agricultural sites are not yet developed, this calculation is cautiously calculated and further research could gradually add base reference data for understanding the distribution, ecological risk, and trophic transfer of MPs.

This study addresses the global plastic waste crisis and the urban heat island effect by developing an innovative solution: recycled plastic roof tiles embedded with phase change material (PCM) and coated with hollow-glass-microsphere-based white paint. The samples were fabricated with cow pie fibers, OM37 and OM42 PCM materials with different wt./vol. values, i.e., 15/50, 20/50, 25/50, 30/50 ratios. The fabricated tiles were coated with hollow glass microspheres to provide a reflective layer. The tiles’ effectiveness was evaluated through morphological examination and thermal analysis. The SEM analysis revealed an excellent bonding ability for the PCM blend, i.e., OM37 and OM42 at a 20/50 ratio (wt./vol.) with cow pie fibers. Adding cow pie fibers to the PCM shifted the melting points of OM37 and OM42, indicating an increased heat storage capacity in both blends. The thermal conductivity results revealed decreased thermal conductivity with an increased cow pie fiber percentage. The recycled plastic roof tile of the PCM composite at a 20/50 (wt./vol.) ratio showed good thermal properties. Upon testing in real-time conditions in a physical setup, the roof tiles showed a temperature reduction of 8 °C from outdoors to indoors during the peak of summer. In winter, cozy temperatures were maintained indoors due to the heat regulation from the roof.
