电气和电子设备 (EEE) 技术创新与废弃电气和电子设备 (WEEE) 管理策略密切相关。它不仅通过产品更换影响WEEE产生的数量和速度，而且还对EEE系统的环境绩效产生整体长期影响。因此，应对这些影响进行定量评估。开发了概念框架并将其应用于显示产品技术创新的案例研究，并提出了多生命周期评估方法来评估技术创新对多代系统的环境影响。该研究得出的结论是，不断的电子电气设备技术创新以及频繁的产品更换可能会导致报废电子电气设备产生量的剧烈波动以及显着的多代产品系统环境影响。因此，以产品为导向的环境政策，包括废物管理政策，应考虑技术创新。
Electrical and Electronic Equipment (EEE) technology innovation is strongly related to Waste Electrical and Electronic Equipment (WEEE) management strategies. It does not only effect the amount and speed of WEEE generation through products replacement, but it also exerts overall long-term impacts on the environmental performance of EEE system. Therefore, those impacts should be evaluated quantitatively. A concept framework is developed and applied in the case study of display product technology innovation, and a Multi-Life Cycle Assessment method is proposed to evaluate the environmental impacts of technology innovation on multi-generation systems. The study concludes that constant EEE technology innovation along with frequent product replacement may lead to acute fluctuations of WEEE generation and significant multi-generation products system environmental impacts. Hence, the product-oriented environmental policies, including waste management policies, should take technology innovation into consideration.
