There is a growth of social concern regarding the deterioration of the environment. This has boosted the promotion of more efficient and sustainable mechanisms to deal with waste management. In Spain, waste management authorities and related organisations have engaged in a debate about the desirability to implement a packaging Deposit and Refund System (DRS). Under a DRS, consumers have to pay a “packaging deposit” as an added price to products purchased. This deposit is refunded when consumers return the used packaging to the point of sale in perfect conditions for identification. The implementation of such a system implies an important expense of resources. Its effectiveness in increasing the recycling rates crucially depends on public involvement and participation. This paper is grounded in previous studies on attitudes towards recycling. It presents the results of qualitative research performed to capture those factors that are determinant of the expected behaviour of citizens under the proposed DRS. The results indicate that the public perception of the DRS is very sensitive to the information provided. The description of some of the distinctive features of the new system, such as the mechanism associated with the economic deposit or the procedure to return packages, ultimately result in a rather negative evaluation and a reduced predisposition to participate in the waste collection. This study contributes to the analysis of what factors determine the adoption of the DRS, which is key to its success. It indicates that, beyond first impressions, the provision of information describing its features hinders the public's perception and has the potential to modify waste recycling behaviour.

关于环境恶化的社会关注日益增加。这促进了促进更有效和可持续的机制来处理废物管理。在西班牙，废物管理当局和相关组织就是否需要实施包装式存入和退款系统（DRS）进行了辩论。根据DRS，消费者必须支付“包装押金”作为购买产品的附加价格。当消费者在理想的条件下将用过的包装返回销售点时，这笔押金将退还。这种系统的实施意味着资源的重要消耗。其提高回收率的有效性关键取决于公众的参与和参与。本文基于以往对回收利用态度的研究。它提供了定性研究的结果，以捕获那些决定拟议DRS下公民预期行为的因素。结果表明，公众对DRS的看法对所提供的信息非常敏感。对新系统某些独特特征的描述，例如与经济保证金相关的机制或退回包裹的程序，最终导致相当负面的评估，并减少了参与废物收集的易感性。这项研究有助于分析哪些因素决定采用DRS，这是其成功的关键。它表明，除了第一印象之外，提供描述其特征的信息还阻碍了公众
