塑料污染是一个全球性的环境问题，已经实施了几种方法来减少和控制塑料废物的排放，特别是在海洋环境中。最近，有关海滩清洁活动中收集的垃圾中一次性塑料吸管出现情况的数据披露，引发了一场全球运动，导致多个国家禁止使用这些物品。然后，市场很快开始提供可持续的解决方案，如可生物降解的塑料吸管。然而，绿色清洗的情况加上目前与用于证明商业塑料产品生物降解性的技术标准有关的限制，可能导致这些措施在很大程度上无效。在此，一项评估巴西和美国销售的塑料吸管成分的案例研究被用作讨论这个被忽视的问题的背景，这个问题远远超出了塑料吸管。因此，尽管一些地方法规已经禁止使用一次性塑料产品，但应在区域和全球范围内采取更多行动，特别是在对所谓的可生物降解产品进行适当标签方面。因此，从多维度的角度来看，考虑到强大的塑料行业的阻力，以教育人们为重点的多种管理策略-根据正确的标签决定购买并正确丢弃废物-可能是我们推动积极的全球环境变化的最佳机会。此外，我们还建议将这一相关主题纳入巴塞尔公约塑料废物伙伴关系提出的任务。
Plastic pollution is a global environmental concern and several approaches have been implemented seeking to reduce and control releases of plastic waste, especially in marine environments. Recently, disclosure of data on occurrence of single-use plastic straws among the litter collected in beach cleaning campaigns unleashed a worldwide movement that resulted on banning of these items in several countries. The market then quickly began to offer sustainable solutions as the professed biodegradable plastic straws. However, cases of greenwashing added to current limitations related to the technical standards used to attest biodegradability of commercial plastic products may lead these measures to be largely ineffective. Herein, a case study assessing the composition of plastic straws marketed in Brazil and United States under false claims of biodegradability was used as background for discussion of this neglected issue, which goes far beyond plastics straws. Thus, although some local regulations have already banned single-use plastic products, additional actions in regional and global scales should be implemented, especially concerning proper labeling of the alleged biodegradable products. Therefore, from a multi-dimensional perspective and considering the resistance of the powerful plastic industry, multiple management strategies focused on educating people – in the matters of deciding purchases based on correct labeling and properly discarding the waste –, are possibly our best chance to drive a positive global environmental change. Additionally, we also suggest the inclusion of this relevant subject among the tasks proposed by the Basel Convention Partnership on Plastic Waste.
