将消费电子产品系统从线性系统转换为圆形系统有许多关键挑战。在进入市场的快速变化的设备与缓慢发展的自愿设计政策、法规和电子废物处理业务策略之间观察到不匹配。传统的电子废物（电子废物）管理系统在历史上经过优化，可以从相对容易拆卸的大型产品中提取高价值组件，但现在进入废物流的产品通常是轻型移动设备，通常不受法规的保护，或者不含高浓度的有价金属。本文提出，旨在关闭物质循环的电子废物处理系统的转变应该着眼于自然生态系统中的循环过程，这些循环过程已经演变为优化闭环营养循环。就像自然界中的物种一样，电子垃圾处理者决定在哪里“吃”和“吃”什么，平衡食物的质量和丰富程度以及获取食物所消耗的能量。根据最优觅食理论的概念，我们在这里展示了一个概念框架，该框架将生态世界和工业世界的觅食行为联系起来，评估了四种可能应用于电子垃圾案例的潜在数学模型，并展示了最优觅食决策如何指导商业、设计和终端管理，以实现消费电子系统的循环经济目标。
Converting the consumer electronic product system from a linear system to a circular one has a number of key challenges. A mismatch is observed between the rapidly changing devices entering the market and the slowly evolving voluntary design policies, regulations, and e-waste processing business strategies. Conventional electronic waste (e-waste) management systems were historically optimized to extract high-value components from large products that were relatively easy to disassemble, but the products now entering the waste stream are more often light-weight mobile devices that are typically not covered by regulations or do not contain as high a concentration of valuable metals. This article proposes that transformations in the e-waste processing system aimed at closing the material loop should look to the circular processes found in natural ecosystems, which have evolved to optimize closed loop nutrient cycling. Like species in nature, e-waste processors make decisions about where and what to “eat,” balancing a food’s quality and abundance with the energy expended in obtaining it. Adapting the concept of optimal foraging theory, we demonstrate here a conceptual framework that draws parallels between foraging behavior in the ecological and industrial world, evaluates four potential mathematical models that case be applied to the e-waste case, and demonstrate how optimal foraging decisions can guide business, design, and end of life management toward circular economy goals in the consumer electronic system.
