• So-called biodegradable plastics and greenwashing are issues of environmental concern. • Cases of false claims of biodegradability in plastic products are becoming frequent. • Appropriate labeling rules for biodegradable products should be implemented. 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. [ABSTRACT FROM AUTHOR]

Goal: Understand the environmental impact of brewing industry activities in Brazil. Design/Methodology/Approach: Discusses the model of production and consumption tied to the brewing market within the environmental debate. By bibliographical research, qualitative approach, case study. The case study data was collected within a three-month period on Ambev's sustainability program analysis. Limitations: Enterprise's confidentiality. Some documents could not be reached. Results: This study clarify that Ambev's sustainability program does not meet its own objectives and statements as it does not effectively contribute to sustainability. Practical Implications: This article's value resides in revealing Ambev's greenwashing strategies deepening the effects of environmental crisis worldwide. Originality/Value: This study arises a critical thinking regarding big companies sustainability initiatives lacking real environmental concern. [ABSTRACT FROM AUTHOR]

Concerns about plastic pollution and global public policies have encouraged consumers to acquire environmentally friendly products. Thus, products made of biodegradable plastics have been preferred by the public, despite their costs. However, greenwashing practices, promising more environmental benefits than the products actually offer, has become frequent. Nevertheless, no studies assessing the occurrence of greenwashing in commercial plastic products sold in large world economies have been performed. The present study aimed to experimentally evaluate alterations in structure and chemical composition of selected plastic products marketed in Canada, USA and Brazil. The aging experiments carried out by seawater immersion for 180 days showed no evidence of degradation in 4 out of the 6 studied samples, despite product claims of biodegradability or 100% degradability status. This finding denotes unequivocal greenwashing practices, even including bags made of polyethylene, an ordinary non-biodegradable polymer. Thus, the inadequate adoption of green marketing is deceiving to consumers and may lead to improper disposal of these materials. These practices are highly counterproductive in view of the global public policies recently adopted to control plastic pollution. Therefore, considering the technologies currently available for identification of polymers, a strict control should be exercised over products that claim biodegradable status., (Copyright © 2018 Elsevier B.V.
