A Critical Review of Consumer Perception and Environmental Impacts of Bioplastics in Sustainable Food Packaging
AI summary Read the abstract
This review of bioplastic food packaging finds that consumers are broadly supportive of bioplastics but hold unrealistically high expectations—assuming all bioplastics are both renewable and fully biodegradable—while also lacking practical knowledge of how to properly sort and dispose of them, highlighting critical gaps in public education and policy.
As awareness of environmental issues deepens and the demand for sustainability grows among societies, businesses, and consumers, minimizing the environmental impact of food packaging has become increasingly important. Bioplastics offer a promising solution due to their use of renewable resources (such as plants), their biodegradability, and their ability to retain the protective properties of traditional plastics. This review discusses recent advancements and trends in sustainable food packaging, emphasizing the role of bioplastics. Several typical types of bioplastics are introduced, along with an analysis of their advantages and limitations. Furthermore, this study investigates consumers’ attitudes toward bioplastic food packaging, emphasizing their perceptions of its sustainability and practical use. The findings reveal that consumers generally hold a positive attitude toward bioplastics, particularly appreciating their biodegradable and compostable properties. However, their expectations are often overly high, as they believe bioplastics must meet two key criteria: being made from renewable raw materials and being fully biodegradable or compostable. Additionally, most consumers lack the knowledge or ability to dispose of bioplastic waste properly. This issue highlights two critical areas for policymakers: aligning consumer expectations with realistic sustainability goals and educating the public on correct waste sorting and disposal practices.

An assessment of attitudes towards plastics and bioplastics in Europe
AI summary Read the abstract
Researchers surveyed European consumers about their attitudes toward conventional plastics and bioplastics, finding that most participants were aware of plastic's environmental and health risks and practiced waste segregation, yet limited availability of bioplastics and insufficient public information remained key barriers to wider adoption. Packaging was identified as the most frequent plastic use category among respondents.
Consumer attitudes and concerns with bioplastics use: An international study
AI summary Read the abstract
Researchers surveyed consumers across 42 countries about their knowledge and attitudes toward bioplastics as an alternative to conventional plastics. The study found that while most consumers were concerned about plastic pollution, awareness and understanding of bioplastics varied significantly across regions. The findings suggest that clearer labeling and better public education about bioplastic options could help drive consumer adoption of more sustainable materials.
