The projected 78 million tonnes of photovoltaic waste by 2050 calls for strategies beyond conventional recycling-landfill approaches. This study investigates a Reuse-Recondition-Recycle approach that integrates component-level recovery with environmental and economic assessments across four policy options. Analysis of 50 crystalline silicon modules reveals that comprehensive circular strategies yield significant benefits (−7.8 tCO₂-eq emissions reduction and €1,658 economic gain) compared to landfill disposal (+22.7 tCO₂-eq emissions and €150 economic loss). Life extension pathways deliver superior performance, with 13-fold carbon savings and 11.4-fold revenue increases compared to recycling alone. This investigation demonstrates how condition-based pathway optimization transforms PV waste management into a resource-positive system, with reuse strategies generating 83% of economic value in circular scenarios.

摘要

The projected 78 million tonnes of photovoltaic waste by 2050 calls for strategies beyond conventional recycling-landfill approaches. This study investigates a Reuse-Recondition-Recycle approach that integrates component-level recovery with environmental and economic assessments across four policy options. Analysis of 50 crystalline silicon modules reveals that comprehensive circular strategies yield significant benefits (−7.8 tCO₂-eq emissions reduction and €1,658 economic gain) compared to landfill disposal (+22.7 tCO₂-eq emissions and €150 economic loss). Life extension pathways deliver superior performance, with 13-fold carbon savings and 11.4-fold revenue increases compared to recycling alone. This investigation demonstrates how condition-based pathway optimization transforms PV waste management into a resource-positive system, with reuse strategies generating 83% of economic value in circular scenarios.
