In this study, plastic waste was efficiently converted into valuable energy resources using a unique pyrolysis technique. A carbon-metal oxide hybrid nanocomposite introduced as catalyst, and analyses of structural surface morphology were conducted. Pyrolysis process parameters such temperature (PTemp), time (PTime), catalyst concentration (CC) optimized through response methodology for higher yield resources. Char underwent proximate ultimate analyses, oil physicochemical Fourier transform infrared syngas composition determined. Optimal conditions found: PTemp 300 °C, PTime 60 min, CC 1 % char; 465 150 oil; 550 4 syngas. Compared to the ZSM-5 char, oil, yields increased by 7.9 %, 10.8 7.2 respectively, at optimum conditions. These findings suggest that can effectively meet demands with enhanced outputs.

This study investigates the integration of recycled and natural fibers with concrete aggregates to develop environmentally friendly fiber-reinforced (FRC), a primary aim maintaining or enhancing its properties. Four mixtures, namely plain (C-Plain), steel (C-RSF), plastic (C-RPF), kenaf (C-KF), were formulated analyzed for their fresh, hardened, durability characteristics. A 50% replacement coarse aggregates' weight (RCA) was implemented. By standardizing fiber volume fractions at 1.0% all FRC evaluated properties such as workability, dry density, ultrasonic pulse velocity (UPV), compressive strength, modulus elasticity, post-cracking flexural performance, rupture, toughness, splitting tensile freeze-thaw resistance after 100 300 cycles. Testing involved three specimens each parameter 7 28 days. The results indicated positive effects on incorporation fibers. Notably, C-RSF demonstrated highest strength (46.63 MPa), toughness (64.35 kN-mm), rupture (7.46 MPa) compared other composites. Additionally, it exhibited minimal loss (2.18% 3.07%) cycles, indicating exceptional durability. superior while C-KF showed enhancement slightly below that C-RSF. Although not reaching level C-RSF, C-RPF positively influenced performance. Compressive response either maintained performance marginal reduction. findings carry significant implications developing conscious construction materials enhanced mechanical properties, thereby advancing sustainable practices.
