The circular economy is a way of eliminating the shortage of raw materials that Europe is currently facing. However, it is necessary to explicitly identify the problems that prevent greater involvement in the CE. This article is focused on consumers and how they treat discarded or non-functional items. The aim was to fill the research gap, i.e. to compile a suitable CE model and define a methodology that would ensure the efficient disposal of non-functional or unsuitable items by consumers. An original methodology was drawn up to conduct the representative research, designed to lead to the practical application of the proposed CE model. The research explored how consumers treat non-functional or unsuitable items, the costs they incur in discarding, renovating, reusing, and recycling such items, and the alternative costs of unsorted municipal waste. After the data had been implemented into the model the circular economy was proven to have an economic benefit for the national economy in all groups. However, the economic disadvantage for consumers was also calculated, where the cost of involvement in the CE is higher than the cost of unsorted municipal waste. This means that people are motivated to play a part in the CE more by their own responsible approach to life, or social pressure from those around them. Based on this research it may be said that economic aspects are one reason that consumers tend to be reluctant to get more involved in the CE. Unless there is a significant rise in the cost of municipal waste that would motivate consumers to move towards the CE for financial reasons, in order to support the CE consumers need to be better stimulated, educated and informed as much as possible through the media.循环经济（circular economy）是破解欧洲当前面临的原材料短缺困境的有效路径。然而，亟需明晰识别掣肘民众更深度参与循环经济的各类问题。本文以消费者群体为核心研究对象，聚焦其对废弃或失效物品的处置行为。本研究旨在填补现有学术空白，即构建适配的循环经济模型，并确立一套可保障消费者高效处置失效或不适宜物品的方法论体系。本次研究拟定了原创方法论以开展代表性调研，旨在推动所提出的循环经济模型实现落地应用。调研剖析了消费者对失效或不适宜物品的处置方式、其在丢弃、翻新、复用及回收此类物品过程中产生的各类成本，以及未分类市政垃圾的替代成本。将调研数据导入模型后，研究证实循环经济对全群体国民经济均具备正向经济效益。但同时也测算出消费者面临的经济劣势：参与循环经济的成本高于未分类市政垃圾处理成本。这意味着，消费者更深度参与循环经济的动力，主要源自自身的生活责任意识，或是来自周遭群体的社会压力。基于本次调研可得出结论：经济因素是消费者不愿更深度参与循环经济的重要动因之一。除非市政垃圾处理成本大幅上涨，促使消费者出于经济考量转向循环经济模式，否则为推动循环经济发展，需通过媒体等渠道对消费者进行更充分的激励、教育与信息科普。
