Simulation Inspection Year: 2050 High Income: 31.4% | Emerging: 68.6%

Key Structural Transition: High-income economies dominate global PV waste through the 2020s and 2030s (~84% in 2030) due to 2005–2020 installations. Massive post-2022 deployment in emerging markets crosses the tipping point in 2041, shifting circular logistics demands to developing economies.
