Alarming plastic production growth worldwide reinforces the public debate about the prevailing environmental crisis, whereby single-use-plastic (SUP) items are considered as by far the most harmful to the environment and public health. Accordingly, European environmental policy aims at eliminating SUP. Recently, we presented a model of plastic governance that derives from a circular economy approach identifying and taking into consideration perspectives of different actors in the plastic governance, such as producers, wholesalers, shop keepers, consumers, citizen scientists, and academia. Our results illustrate that the vast majority of stakeholders cared for the natural environment and understood the need to phase out SUP from the global economy. We proposed that a knowledge brokerage, undertaken by scientists via means of citizen science, as the most effective method to implement elimination policy, as it provides stakeholders with knowledge on why and how to handle SUP issues. However, at the time of the global COVID-19 pandemic, a plastic governance model required a re-assessment. The perceived role of SUP has changed, as it reflects the health emergency. Namely, due to the health safety reasons stakeholders and consumers are requesting even more SUP than previously. Following up on our data gathered prior to the pandemic, we suggest that under the new circumstances health concerns outweigh the environmental concerns being determined by a shift in the value hierarchization. The paper discusses preliminary results.

The alarming increase in single-use plastic (SUP) consumption, exacerbated by the COVID-19 pandemic and its detrimental effects on environmental and public health, underscores the urgent need for the public to adopt more environmentally responsible behaviours. This study presents citizen science (CS) initiatives undertaken two years after the onset of the pandemic as an effective means to engage and mobilise citizens in reducing plastic consumption. It combines an inventory of CS actions targeting SUP with a self-designed and implemented CS project. Unlike the predominantly technical focus of existing initiatives, our ‘Plastic Detective’ project was designed to collect behavioural data related to SUP use. The majority of completed and ongoing CS projects addressing SUPs focused on beach clean-ups, which primarily involved reporting the distribution and composition of plastic litter. However, no initiatives were found to address consumer behaviour. CS activities were predominantly initiated in a bottom-up manner, largely coordinated by non-governmental organisations (NGOs), and were mostly confined to the Northern Hemisphere. In our project, volunteers were asked to observe, sample and categorise behaviours in their surroundings using a model that distinguished between SUP use and the adoption of alternative materials or practices. Additionally, participants’ perceptions of SUP were assessed through pre- and post-surveys. Our findings reveal that young people, in particular, are eager to participate in CS initiatives. Regardless of age, gender or location, all respondents—despite acknowledging the need to reduce SUP consumption—identified producers as the key group responsible for addressing plastic pollution. We conclude that CS can act as an effective knowledge broker between research and non-research communities, fostering behavioural change towards more sustainable practices. Moreover, CS initiatives can play a vital role in popularising scientific findings and influencing policy-making processes to promote environmentally friendly alternatives to SUPs.

The world faces an alarming plastic waste problem. The volume of plastic waste is rapidly and continuously increasing, mainly due to the single-use plastics overconsumption, whereas its recycling and utilization leave much to be desired. Despite the negative effects of plastic on the environment and public health, the COVID-19 outbreak shifted the public attention away from the environmental issues, potentially giving space for extended lobbyism by interest groups and industry to delay or even prevent legislation to combat plastic pollution. Our study aims to understand how the media discourse on single-use plastic (SUP) in particular, evolves in the course of the pandemic. How it vary across EU Member States? For this purpose, we specifically analyse plastic-related articles in major prestigious daily newspapers published between June 2019 and June 2021 in four EU Member States: Germany, France, Italy, and Poland, as countries with different levels of sustainable transition to form a representative model of an European context. Additionally, between November 2022 and January 2023, we conducted a series of interviews via Google Meet, with journalists who agreed to be asked on the plastic issues they upraised. Our analysis initially covered 1076 articles, out of which 198 articles were rejected due to non-compliance with the subject or repetition, leaving 878 articles forming the database for eventual analysis. Specifically, we outline a key impact of the COVID-19 pandemic followed by a clear evolution on the number of plastic-related articles, on related stakeholder engagement, and the focus on specific SUP items. Moreover, we address a research gap - presenting a media portrait of different types of SUP in more details and highlighting the significance based on several culturally and linguistically very different countries within a single supranational state (EU). A clear trend reversal towards an informed knowledge circulation across the circular economy model of single-use plastics is ultimately essential to develop sustainable solutions to reject the disposable culture, stop the waste of natural resources, and reduce the consumption of oil or gas for plastic production and thus protect the climate.
