The demand of products that incorporate circular requirements depend on consumer perceptions. So effective communication is necessary between the product and consumers through product labelling. The use of specific icons facilitates this communication. This study presents a methodology for identifying the icons that best associate and identify consumers with the different design requirements that a circular product should meet. To do this, a set of icons for each circular requirement (upgrade, disassembly, lifetime extension, repairability and reuse) is presented to a representative sample of consumers who select the preferred one by taking into account different icon characteristics (simplicity, familiarity, semantic distance and aesthetic appeal). To validate the comprehension of the selected icons, ISO 9186-3 was applied to test the association of the selected icons with their corresponding requirement. Multinomial regression models were applied to explore whether any significant differences appeared among the responses obtained (icon selection) by the different respondent profiles. The most significant socio-economic variables were gender and age, while the most significant icon characteristics were semantic distance and aesthetic appeal. The results of this study could be useful for the companies committed to integrate the principles of circular economy into their product design since the use of selected icons can help consumers to identify them. Consumers' understanding is ensured due to the high percentages of correct answers obtained in the validation test (>85%).

包含循环需求的产品的需求取决于消费者的看法。因此，必须通过产品标签在产品和消费者之间进行有效的沟通。特定图标的使用促进了这种交流。这项研究提出了一种识别图标的方法，该图标可以最佳地关联和识别具有圆形产品应满足的不同设计要求的消费者。为此，将针对每个循环需求（升级，拆卸，使用寿命延长，可维修性和可重复使用性）的一组图标呈现给代表性的消费者样本，这些样本的消费者通过考虑不同的图标特征（简单性，熟悉性，语义）来选择首选图标距离和美学吸引力）。要验证对所选图标的理解，应用ISO 9186-3来测试所选图标与它们相应要求的关联。应用多项式回归模型来探索在通过不同的响应者配置文件获得的响应（图标选择）之间是否出现任何显着差异。最重要的社会经济变量是性别和年龄，而最重要的偶像特征是语义距离和审美吸引力。这项研究的结果对于致力于将循环经济原理整合到其产品设计中的公司可能是有用的，因为使用选定的图标可以帮助消费者识别它们。验证测试中获得的正确答案的百分比很高（> 85％），从而确保了消费者的理解。应用多项式回归模型来探索在通过不同的响应者配置文件获得的响应（图标选择）之间是否出现任何显着差异。最重要的社会经济变量是性别和年龄，而最重要的偶像特征是语义距离和审美吸引力。这项研究的结果对于致力于将循环经济原理整合到其产品设计中的公司可能是有用的，因为使用选定的图标可以帮助消费者识别它们。验证测试中获得的正确答案的百分比很高（> 85％），从而确保了消费者的理解。应用多项式回归模型来探索在通过不同的响应者资料获得的响应（图标选择）之间是否出现任何显着差异。最重要的社会经济变量是性别和年龄，而最重要的偶像特征是语义距离和审美吸引力。这项研究的结果对于致力于将循环经济原理整合到其产品设计中的公司可能是有用的，因为使用选定的图标可以帮助消费者识别它们。验证测试中获得的正确答案的百分比很高（> 85％），从而确保了消费者的理解。
