“…Therefore, mechanical property measurements for polymers are critical and should be sufficiently investigated. [87] The tensile test is not only a standard engineering test for measuring mechanical properties but also the most vital test for assessing the mechanical attributes of a material. [88] Krishna et al studied a nanocellulose-based nylon six nanocomposite, comparing the experimental data using a universal testing machine (UTM) and simulations (Figure 4b).…”

This review addresses the environmental challenges arising from the proliferation of plastic and electronic waste (E‐waste), driven by global economic and demographic expansion. Since the 1950s, the mass production of plastics has seriously threatened global sustainability, lacking effective post‐use management. E‐waste worsens the issue due to low recyclability and high toxicity. Resolving this requires improving biodegradability. The paper explores eco‐friendly biodegradable materials for a zero‐e‐waste society, focusing on multifunctional plastics in electronics, providing a comprehensive guide to material selection, and illustrating novel concepts through recent trials. The goal is fully biodegradable electronics, but transitioning from conventional material systems is complex. Notably, rendering engineering plastics in electronics biodegradable surpasses simply substituting conventional plastics. Thus, it is delved into various research initiatives focused on biodegradable materials for electronics, highlighting a systematic approach toward creating a fully integrated, biodegradable electronic system. This includes exploring the mechanisms of biodegradation and the integration of printed circuit boards (PCBs), a critical component in electronics. Achieving this represents a challenging but promising step toward a sustainable electronic future.

This study presents an analysis of airflow through prism obstacles inside a trapezoidal solar air heater channel using a computational fluid dynamics method. The purpose is to now the best configuration of gap ratio (S/H) 0.7, 1, 1.3 for 30° obstacle folded angle. The air is 2.62 m/s and the air temperature is 299 K. The channel wall boundary condition is heat flux with a constant value of 620 W/m2 is attached alongside the wall of the channel. The equation is Pressure-velocity coupling performed with SIMPLE. Renormalization-group (RNG) k-ε is chosen as a turbulent model. The simulation result presents temperature distribution, airflow vector in the middle plane of a channel. The obstacle can create backflow. It can increase the air temperature in a channel.
