Microplastics in seafood: Consumer preferences and valuation for mitigation technologies
AI summary Read the abstract
A consumer survey in Chile found that people were willing to pay about US$4 extra for mussels certified to have 90% lower microplastic content, and informing consumers about health risks increased that price premium by 56%. This signals a market opening for microplastic mitigation technologies in seafood and highlights how public awareness of health risks can drive demand for cleaner food products.
Abstract Microplastics, an emerging pollutant, have garnered widespread attention due to potential repercussions on human health and the environment. Given the critical role of seafood in food security, growing concerns about microplastics might be detrimental to meeting future global food demand. This study employs a discrete choice experiment to investigate Chilean consumers' preferences for technology aimed at mitigating microplastic levels in mussels. Using a between-subjects design with information treatments, we examined the impact of informing consumers about potential human health and environmental effects linked to microplastics pollution on their valuation for the technology. We found that the information treatments increased consumers’ willingness to pay for them. Specifically, consumers’ willingness to pay for mussels with a 90% depuration efficiency certification is around US$ 4. The provision of health impact information increased the price premium by 56%, while the provision of environmental information increased it by 21%. Furthermore, combined health and environmental information significantly increased the probability of non-purchasing behavior by 22.8% and the risk perception of microplastics for human health by 5.8%. These results emphasize the critical role of information in shaping consumer preferences and provide evidence for validating investment in research and development related to microplastic pollution mitigation measures.

Microplastics in seafood: Consumer preferences and valuation for mitigation technologies
AI summary Read the abstract
A consumer study in Chile found that people were willing to pay significantly more for mussels certified to have reduced microplastic contamination, with information about health risks increasing willingness to pay by 56%. However, combined health and environmental information also made some consumers less likely to buy mussels at all, suggesting that microplastic awareness could reduce seafood consumption. These findings highlight the economic importance of developing microplastic mitigation technologies for the seafood industry.
Can we shop ourselves to a clean sea? An experimental panel approach to assess the persuasiveness of private labels as a private governance approach to microplastic pollution
AI summary Read the abstract
An experimental consumer survey in Norway, Germany, and Portugal found that people are willing to pay a premium for products certified as microplastic-free, suggesting that private certification schemes could be an effective market-based tool for reducing microplastic pollution. However, willingness to pay was influenced by country, trust in certifiers, and how the certification was framed.
Nudging consumers about the issue of microplastics: an experimental auction study on valuation for sustainable food packaging
AI summary Read the abstract
Researchers used an experimental auction to study whether informing consumers about microplastic pollution changes how much they are willing to pay for sustainable food packaging. They found that consumers offered significantly more for pasta products packaged in biodegradable materials with environmental footprint labels, especially after learning about microplastic risks. The study suggests that transparent labeling combined with consumer education could be an effective way to shift purchasing behavior toward more sustainable options.
Consumers’ perceptions and willingness to pay for a hypothetical microplastics-free labelled bottled water: an empirical study in Italy
AI summary Read the abstract
Researchers surveyed 344 Italian consumers and found that awareness of microplastics in bottled water, pro-environmental attitudes, and health concerns all increased people's willingness to pay a premium for water labeled "microplastic-free." However, price sensitivity remained a strong barrier, suggesting that microplastic-free products must be priced carefully to reach mainstream markets.
Information Nudges and Consumer Willingness to Invest in Microplastic-Free Water
AI summary Read the abstract
This study design tests whether providing consumers with specific information about microplastic concentrations in their primary drinking water source increases their willingness to pay for a certified microplastic-removing water filter, using a randomized online choice experiment. Understanding the behavioral economics of microplastic risk communication is important for designing effective public health messaging and identifying market demand for filtration solutions.
