• • The dismantling of waste TVs yields net environmental benefits: fossil resource scarcity reduced by 26,494.23 kg oil eq, freshwater ecotoxicity reduced by 2.21×10^4 kg 1,4-DCB, and greenhouse gas emissions reduced by 956.53 kg CO2 eq per functional unit (midpoint indicators).
• • Endpoint impact reductions include 1.59×10^4 DALY (human health), 2.35×10^4 species·yr (ecosystem), and $4.22×10^4 (resource depletion), demonstrating significant positive contributions to sustainability.
• • The carbon footprint per waste TV is 0.231–0.247 kg CO2 eq per unit, with electricity consumption accounting for over 50% of total emissions; TV-2 (0.231) shows a 6.5% lower footprint than TV-1 (0.247), indicating potential for energy efficiency improvements.
• • Sensitivity analysis confirms that electricity consumption is the most influential parameter on carbon footprint, highlighting the importance of equipment upgrades and energy management for emission reduction.
