An important ingredient of this shift is the introduction of lightweight, high-performance materials including the use of advanced polymer composites (e.g., glass fiber-reinforced polymers, carbon fiber composite and natural fiber-reinforced thermoplastic composite) as eco-friendly substitutes to traditional automotive parts. As the future of mobility increasingly leans toward electric vehicles(EV), the demand for eco-friendly materials has never been greater. The review entails a comprehensive discussion of natural fibers and fillers of agro/food waste including banana fiber, coir, date palm fiber, pineapple leaf fiber(PALF), and sugarcane bagasse as reinforcement materials to be used in biocomposites in EV interiors. It discusses the procedures of extracting these fibers, its physical, chemical, mechanical and thermal characterization and the performance of its reinforced composite. Also, the paper provides an in-depth analysis of car interior material specifications, low density, sufficient stiffness, thermal stability, flame retardancy, low volatile organic compound(VOC) emissions, odor containment, fogging resistance, UV stability, and recyclability.

Salinity increasingly constrains wheat establishment in salt-affected irrigated areas. Raw Posidonia oceanica residue (RPO) and its biochars produced at 350 °C (POB1) and 550 °C (POB2) were evaluated as waste-derived amendments to improve wheat germination under saline and non-saline conditions.

Germination capacity (GC), germination rate index (GRI), seedling vigor index (SVI), shoot and root growth, biomass, and water content were recorded after 12 days. Under salinity, Kaşifbey 95 remained relatively stable, whereas Gönen 98 showed the strongest overall response. RPO, including at 250 mg dish⁻¹, generally enhanced germination, vigor, root development, and water status, whereas PO-derived biochars were neutral or inhibitory at higher rates.

Drawing on focus group discussions and stakeholder interviews with households, traders, recyclers, informal waste workers, producers of alternatives, regulators, and academics in both countries, the study analyzes how governance capacity, market structure, and actor inclusion shape policy outcomes. The findings show that Tanzania’s ban achieved visible reductions in plastic litter and high compliance among producers, driven by clear regulatory signals and enforcement, but faced persistent challenges related to consumer awareness, the affordability of alternatives, informal leakage, and cross-border trade. Nigeria, by contrast, exhibits a fragmented but innovation-driven plastic economy, anchored in informal recovery networks and in the uneven implementation of Extended Producer Responsibility (EPR). The comparative evidence suggests that plastic bans implemented without affordable substitutes, phased sequencing, and integration of informal actors’ risk regulatory displacement and livelihood disruption.
