Results and Discussion

 

As we mentioned, a large amount of research about CE has been published (Gil-Lamata, Latorre-Martínez, 2022; Anaruma et al. 2022). The goal of the paper is to map the communication about CE on the Twitter platform (platform X for this time). We analyze the amount of 630 125 tweets between 1.1. 2010 - 30.4. 2023. The communication about circular economy is a key factor to: analyze the current situation, change consumers habits or understand companies’ behavior.

 

During the communication monitoring we were analyzing the hashtag “#circulareconomy” and the supplementary hashtags. Those associations help us to understand what circular economy means on social media.  “Circular economy” and “sustainable development” were the most frequent keywords because they define the focus area of the studies.

 

As can be seen in Table 1 when comparing Twitter communications along with published scientific articles, sustainability and waste are a major part of publications and communications in addition to the circular economy. In other approaches, the scientific articles differ significantly, especially in the approach where the most frequent connections identified in circular economy are Economy, Sustainable development, Recycling, Use, Research, Business, Value a Product (Gil-Lamata and Latorre-Martínez, 2022).

Twitter communication mainly mentions Waste, Recycle, Plastic, Zerowaste, SDGS, CSR and EU. There is a noticeable focus on communicating topics in conjunction with efforts to address societal issues through CE. There are also trend words that appear to a lesser extent such as Zerowaste, ESG, Blockchain and so on.

 

During the hashtag analyses we recognized 100 most co-occurring hashtags in total (see in Table: 1 Most co-occurring hashtags). Main theory of the circular economy is based on 4R (Kirchherr et al. 2023). Words such as Reduce, Reuse, Recycle, Recovery are associated with the concept of CE. In communication on Twitter, we find this 4R mainly represented by those hashtags:

  • Recycle: #recycling, #recycle, #recycled (34 198).
  • Reuse: #reuse (10 370).
  • Recovery: #energy, #renewables, #cleanenergy (7 724).
  • Reduce: #reduce (1 598).

The most used hashtag from 4R is directly associated with Recycle. If we add upcycling as part of recycling, the total number of tweets will be 38 thousand. Same results in (4R) core principles found in (Kirchherr et al. 2023) in systematic review of 114 definitions of circular economy. They examine the main principles of circular economy as Recycling.

 

Most frequent hashtags associated with circular economy are: #sustainability, #recycling, #waste, #sustainable, #environment.

Topics Analysis

 

In communication on twitter the similar keywords are concentrated into topics. Twitter communication connected to the circular economy is divided into nine main topics. The description of all topics is based on the structure of hashtags.

Topic analysis describes the biggest topics of global communication about the circular economy on Twitter. In social media communication, we can define so-called keywords (Bruns et al. 2016), which serve as an identification of the place (EU) or the key topic of a given group (climatechange), which primarily indicate the focus of a given discussion. These keywords may not be directly the main topic of the communication but define its own impact (geographical or thematic).

The nine largest identified topics of communication about the circular economy (Table 2) contain a total of 521 thousand tweets. Out of a total of 820 thousand tweets containing the hashtag #circulareconomy recorded between 2011 and 2023, they thus account for over 63 % of global communication. The top 9 topics thus comprise most of the global population and through their analysis we can see the main communication streams in the circular economy.

  1. Events

Topic named Events contained all the communication about the social, educational and projects opportunities in the field of circular economy. They are common in all communication field (in hashtag analysis of twitter communication (Šálková et al. 2023) it appears in third place of zero waste communication) - the information about events are communicated across the field in social media. They are focusing on special occasions and organizational information, call for actions (mostly join with us), etc.

Companies are leveraging social media platforms to communicate with their shareholders and engage them in discussions (Mohd-Sulaiman a Hingun 2020). The aim of event tweets is the need to promote events (Koesharijadi, Merthayasa, a Nendi 2022), organized in the context of the circular economy. The effort to promote events from the side of non-profit organizations or business is quite large and generates several phases of communication for each event, ranging from preparation to implementation to feedback (looking back).  In this way, some organizations emphasize the importance of the circular economy (Jones a Comfort 2017) and promote their social responsibility, whether they are non-profit organizations, educational institutions (Kvasnickova Stanislavska et al. 2014) or corporate.  For this reason, the generated area is present in any evaluation and often comes to the fore in the topic area.

Overall, the communication of individual circular economy events takes up almost 30% of all communication, showing that the circular economy publishing community is very active.

 

 

  1. Waste

The second main topic is in the area of waste. It is interesting that the connection with waste management is coming to the forefront of communication in relation to waste. This indicates an overall positive trend of trying to manage production and resource waste. The connection with CE and waste management is illustrated by (Richa, Babbitt, a Gaustad 2017) in connection with the circular economy for end-of-life lithium-ion batteries. Other important components of communication are the approach to addressing waste as a societal problem, here reuse, recycle and reduce approaches are mainly promoted. In general, communication in this area focuses mainly on waste and its reduction through reuse or recycling.

A relatively important area of waste issues is zero waste (Šálková et al. 2023), which also features prominently in this communication.(Ganczewski a Jemielniak 2022) found that a significant number of popular tweets with the #zerowaste hashtag are focused with the food packaging.

In summary, over 11% of all Twitter communication is about waste issues. (Kröhnert a Stucki 2021) note that there is a growing number of small eco-oriented zero waste stores in Europe that serve a specific segment of customers.  Overall, there has been a change in customer behaviour after the Covid-19 pandemic (Zhou a Ai 2022) ,which we do not fully understand (Chen et al. 2021).  The goal of corporate communication, then, is to reach out to customers even with the aforementioned behavioral change. Even plastic reduction through proper waste management, can prevent plastic waste from entering the environment (Borrelle et al. 2020).

 

  1. Climate change

One in ten tweets communicated in relation to the circular economy on Twitter is related to climate change. According to (Connor et al. 2016; Dixon, Hmielowski, a Ma 2017) communicating climate change on social media is strategic to reach a different audience. Communication framed with negative emotions are more likely to match participants' feelings on climate change (Bloodhart, Swim, a Dicicco 2019) This may be related to the fact, as (Pamukçu 2020) points out, that the transition to a circular economy can play a significant role in the fight against climate change. Communication focuses on the connection to climate change itself, but also to carbon, the climate crisis and sustainability. Sustainability in the context of climate change is a common link.

 

  1. Plastic

Plastic reduction has occupied a relatively large part of the road for a long time. Focused mainly on the reduction of packaging plastics, through legislation (Iroegbu et al. 2021) and setting up a recycling system (Molloy et al. 2022). As can be seen from the research recycling captures quite a large amount including plastic pollution issues (Van Emmerik et al. 2020) and microplastics (T. Wang et al. 2022) Technological advancements can play a significant role in plastic reduction, produkci druhotných produktů (J. Wang et al. 2022; Miao, Von Jouanne, a Yokochi 2021). The 4th place in communication indicates a fairly significant component of the overall circular economy communication.7.5 percent of the total communication indicates that despite the long-term resolution of this issue, there is still a need to communicate the topic of plastics even now.

 

  1. Innovation

 

Six percent of communication is focused primarily on modern innovation practices and new business models. Here, companies communicate how their approach has changed, what new technologies are available and where they are heading in the circular economy. Innovation is essential for a circular economy (Panwar a Niesten 2020). Gradually there are tweets that incorporate design and innovative approaches (Konietzko, Bocken, a Hultink 2020) in solving problems are eco-innovations (Maldonado Castro et al. 2022), working with material (Kio, Anumba, a Ali 2022) etc.

 

  1. Circular thinking

In almost five percent of communication, we discover an area that can be linked to circular thinking. This is an area that is by no means insignificant. The area of circular thinking is closely linked to circular economy, changing principles and thinking (Barnabè a Nazir 2022; Iacovidou, Hahladakis, a Purnell 2021; Velte, Scheller, a Steinhilper 2018) sustainability and resource efficiency (Maldonado Castro et al. 2022). Topic circular thinking is based on communication about change, the transition from linear to circular economy (De Mattos a De Albuquerque 2018) and the future. The aim is to change mindsets and promote circularity to change approaches to planning and production.

 

  1. Bioeconomy

Concerns about the future development of society, even in areas such as the bioeconomy, are leading to pressure for innovative approaches that are specifically linked to the circular economy. Measures to reduce the impact on the future are collectively called Circular Bioeconomy (Iacovidou, Hahladakis, a Purnell 2021). The common area of bioeconomy includes communications related to food production (Gkountani a Tsoulfas 2021), bio-waste (Taffuri et al. 2021) and  biodiversity (Stephenson a Damerell 2022).

 

  1. Circular fashion

 

The modern approach in fashion includes textile, cloth and fashion industry. Fashion industry is the third most polluting industry in the world (Papamichael et al. 2023). For this reason, circular fashion has become a part of circular economy concepts worldwide (De Aguiar Hugo, De Nadae, a Da Silva Lima 2021) fulfilling mainly the circular economy branch of reuse (Calaza, Varela Casal, a Valencia 2023). In many developed countries, the circular fashion approach is gradually gaining ground (Dan, 2021) and this is confirmed by the (Dan a Østergaard 2021) and this is confirmed by the 3% in global communication. 

 

  1. EU

The last topic that occupies a more prominent position in communication is the geographical, economic and political marking of communication in relation to the EU. The communication mainly includes the relationship to the enforcement of circular economy and to EU legislation (De Mattos a De Albuquerque 2018). At the same time, there are a number of references to EU policies and individual actions in the circular economy (Yalçın, Paredis, a Jaeger-Erben 2023; Berbel, Mesa‐Pérez, a Simón 2023). The promotion of the circular economy concept on a European scale (Gabor, López–Malest, a Panait 2023) can be assessed at both micro and macroeconomic levels (Moraga et al. 2019). European Union institutions and agencies are actively promoting the circular economy agenda and encouraging sustainable production and consumption behaviors (Camilleri 2020)

 

Sentiment analysis

 

Twitter communication is illustrated by sentiment analysis (see Figure 2), which shows with which connotation the topic is communicated. Sentiment analysis is performed through data mining techniques which help us understand the connotation of a given tweet (Baraibar-Diez, Llorente, a Odriozola 2023).

 

Figure 2: Sentiment analysis

 

 

 

Figure 2 shows the proportions of sentiment in each Topic. The blue component shows the negative communication towards the Topic. As we can see the highest proportion of negative communication is about 12 percent in Topics EU, Plastic and Waste. On the other hand, the highest proportion of positive communication (gray component of the Figure 2) is achieved by Events, Fashion and Business. As we can see, all communicated topics exceed 25 percent of positive communication. With the exception of the already mentioned topic EU.

 

 

Geographic location of tweets

 

In the analysis of the main themes, 9 main areas of communication were identified that describe the core themes.

In addition to the analysis of the structure of the topics communicated and their sentiment, information on geographical locations in terms of the number of tweets in the world is essential for the research. In terms of the locations of tweets about circular economy, the following map (Figure 3) provides an indication of all countries that have reached 100 tweets. In terms of analysis, the United Kingdom (GB) has the highest number of tweets related to the circular economy with 171,000, the United States of America (US), and the EU in general. Alongside Canada and Australia, the world's most populous country - India - then comes to the fore (United Nations b.r.).

Events

 

The high representation of discussions on events in the Netherlands, Belgium, and Germany may be indicative of a strong emphasis on discussing events on Twitter in these countries. This heightened interest could be influenced by several factors. For instance, the study by (Zerback et al. 2020) provides insights into the content analysis of tweets, social media, and online newspapers during the measles outbreak in the Netherlands, reflecting the active engagement with events on social media platforms. Additionally, the research by (Jacobs et al. 2018) discusses the content analysis of immigration news coverage in Flanders and the Netherlands, indicating the extensive coverage of events in these regions. Furthermore, the study by (Kaufhold a Reuter 2016) explores the use of social media during the 2013 European floods in Germany, reflecting the role of digital volunteers and social media in event-related discussions. Moreover, the study by Moran et al. discusses the challenge of incorporating circular economic principles in the fashion industry, reflecting the industry's transition towards sustainable and circular practices. Additionally, the research by (Paprotny et al. 2021) explores the estimation of residential losses from different flood types, indicating the relevance of event-related research in understanding the impact of natural disasters. Furthermore, the study by Moran et al. discusses the capacity of the fashion industry to become sustainable through circular economic principles, reflecting the industry's transition towards sustainable and circular practices.

 

Waste

Based on the analysis of social media data on the topic of waste, it is evident that there is a varying level of interest in waste issues across different countries. The highest interest in the topic of waste is observed in Australia (19,1%) and Canada (16,7%), while the lowest interest is in the Netherlands (7,3%). This discrepancy may indicate a higher public and social commitment to waste issues in Australia and Canada compared to the Netherlands. Several factors could contribute to this observation.

 

The public and social commitment to waste issues in Australia and Canada may be influenced by the reflections on consumer waste and sustainable consumption practices in these countries. Additionally, the study on the virtual waste community in Indonesia illustrates that social media can act as an alternative platform to respond to waste issues (Redyantanu, Yatmo, a Atmodiwirjo 2022). This suggests that the active engagement of social media users in Australia and Canada could be contributing to the higher interest in waste issues observed in these countries.

 

Moreover, the environmental impacts of COVID-19 on Victoria, Australia, have been studied, indicating changes in pollution levels during the pandemic (Boroujeni, Saberian, a Li 2021). This could have raised awareness and concern about environmental issues, including waste management, leading to a higher level of interest in waste-related topics in Australia. Furthermore, the study on medical waste management in Australia highlights the impediments such as lack of awareness and absence of a national policy and regulatory framework for managing medical waste (Andeobu, Wibowo, a Grandhi 2022). These challenges could have prompted increased public attention and commitment to waste issues in Australia.

 

In contrast, the lower interest in waste issues in the Netherlands may be influenced by factors such as unaligned policies and regulations hindering effective waste management practices (Shooshtarian et al. 2022). Additionally, the study on the potential of packaging for reducing fruit and vegetable losses in Sub-Saharan Africa emphasizes the importance of packaging in supporting waste reduction technologies (Tapsoba et al. 2022). The lack of emphasis on such interventions in the Netherlands could contribute to the lower interest in waste-related topics.

 

 

Climate Change

The high percentage of discussion on climate change in Germany, as compared to Belgium, may be influenced by various factors. The power of persuasive narratives and discourses constructed to support climate inaction, as well as the influence of public relations and denial strategies related to climate change, could shape the public interest in climate change topics (Weingart, Engels, a Pansegrau 2000). Additionally, changes to climate change reporting and increasing access to education about climate change issues may reduce anxiety and enhance motivation for positive personal engagement, potentially contributing to the strong public interest in climate change in Germany (Parry, McCarthy, a Clark 2022). Public participation in climate change discussions is considered to resolve differences and promote action, which could be a contributing factor to the high level of interest in climate change in Germany (Zeng 2022). The media's considerable attention to climate change with differences in tone, focus, or the degree of controversy may also influence public interest in the topic (Post 2016). Furthermore, the strategies for climate change communication through social media, which aim to orientate communication objectives, approach citizens effectively, and create interaction with users, could contribute to the high level of discussion on climate change in Germany (León et al. 2023). The message of emergency regarding climate change, as published in the media, together with the social perception of risk, appear to be complex social phenomena with constant feedback, potentially influencing public interest in the topic (Teso-Alonso, Morales-Corral, a Gaitán-Moya 2021). Moreover, the Paris climate negotiations and the approval of the Paris Agreement in Germany may have contributed to the strong public interest in climate change in the country (Gao, Liu, a Yu 2021).

 

Plastic

The extensive discussion on plastics in Germany and the USA, as compared to other countries, may be indicative of a greater public awareness of the problems associated with plastic in these countries. This heightened awareness could be influenced by various factors. For instance, the study by (Jambeck et al. 2015) highlights the significant amount of plastic waste entering the ocean from coastal countries, emphasizing the global scale of the issue (Jambeck et al. 2015). Additionally, the review by (W. C. Li, Tse, a Fok 2016) provides insights into the sources, occurrence, and effects of plastic waste in the marine environment, shedding light on the environmental impact of plastic pollution. Moreover, the study by Wurm et al. discusses the challenges and current status of plastics and the environment in Germany and Australia, providing a localized perspective on the issue (Wurm et al. 2020).

 

Additionally, the study by Andrea et al. emphasizes the global scale of plastics manufacture and production, highlighting the magnitude of the challenge posed by plastic waste (Andrea et al. 2020). Additionally, the research by Dalu et al. explores the integration of management practices for plastic littering in schools, indicating the importance of education and awareness in addressing plastic pollution (Dalu et al. 2020). Moreover, the study by (Van Oosterhout et al. 2022) highlights the low public knowledge on the recyclability of plastics, suggesting a potential area for targeted awareness campaigns. Additionally, the nationwide assessment of plastic pollution in Denmark using citizen science, as conducted by (Syberg et al. 2020), underscores the active involvement of citizens in addressing plastic pollution.

 

In context of previous, the high level of discussion on plastics in Germany and the USA may be influenced by a combination of factors, including the global scale of plastic waste generation, the environmental impact of plastic pollution, challenges and current status of plastics and the environment, education and awareness, public knowledge on recyclability, and citizen involvement in addressing plastic pollution.

 

Innovation
