The consistent rise of the per capita waste generation rate has led to an escalation of waste quantities and the need to expand waste disposal methods. Efforts to develop clean and affordable energy systems are increasingly linked to waste-to-energy as part of the transition to a circular economy (CE). A resource-efficient waste-to-energy business model within a CE offers a variety of environmentally friendly waste management options based on their overall environmental impacts but also makes efficient use of available resources and technologies to convert different types of waste into energy, which helps reduce the adverse effects on the environment and create additional energy sources. This research aims to identify innovative waste management solutions to foster the implementation of CE and a more resource-efficient business model. The research methodology is based on qualitative and quantitative research, triangulation, material flow assessment, and systems dynamics. The value of this study is within the analysis of existing waste-to-energy plant case studies to identify a set of recommendations and appropriate business models for the countries that are at an early stage of evaluation of such facilities. This study found that waste-to-energy plants are critical to achieving the EU's waste disposal targets by 2035. The findings highlight the importance of supporting mechanisms in the waste sector, such as structural funds, as the industry primarily focuses on societal health and safety and environmental protection, alongside resource efficiency and circularity potential.

- Abstract
In the contemporary global context, waste management and the judicious utilization of resources have emerged as pressing concerns. Consequently, the concept of a circular business model has gained prominence as a viable solution. This innovative model reframes waste not as a disposable byproduct but as an opportunity to generate new value, setting it apart from the conventional linear business model, particularly in financial, economic, and operational dimensions. Numerous industries grapple with the issue of excessive waste generation, among them the wine industry, notable for its substantial water and grape waste outputs. This predicament holds significant ramifications both on a global scale and within the specific context of Georgia. Yet, it also presents an innovative avenue for waste recycling. This study draws upon a comprehensive review of internationally recognized literature, noted for their scholarly significance and citation prevalence. In its practical segment, two distinct investment projects have been meticulously developed which seek to evaluate the financial viability of the circular business model in contrast to the conventional linear business model. The investment projects considered are as follows: 1. Under the framework of a linear business model, the company exclusively engages in the production and sale of wine. 2. Within the circular business model paradigm, the company not only produces wine but also harnesses waste processing to yield grape seed oil, which is subsequently marketed alongside wine bottles. Both models undergo rigorous scrutiny, employing a comprehensive analysis of key financial indicators essential for assessing project profitability and efficiency. The outcomes of this investigation reveal that, under identical capital investment conditions, the circular business model surpasses the linear model in terms of profitability. This underscores the potential for sustainable practices within the wine industry and the broader business landscape. [ABSTRACT FROM AUTHOR]

This study aims to investigate to what extent the construction and demolition waste generated by households is managed by the principles of circularity and to identify the main influencing factors in the behavior of households regarding the circularity-based management of construction waste in Latvia. The current research presents principles of circularity of household-generated waste based on a systematic literature review, and the data obtained from a survey were analyzed using both descriptive and inferential statistics. This study clarifies the circular economy rationale for construction and demolition waste (CDW) management in Latvia and proposes further development to promote the achievement of sustainable development goals and increased energy efficiency. The results reveal that the observance of circular economy principles in construction and demolition waste management among Latvian households does not correspond to good circular economy practices due to attitudes toward environmental issues, expenses, and logistics; thus, compliance with these principles and legislation as well as closer cooperation between municipalities and households can promote significant economic benefits.

Environmental sciences ,GE1-350 - Abstract
Modern enterprises are dynamically developing due to the fourth industrial revolution, contributing to the introduction of innovative infocommunication technologies in most business processes, thereby shaping and developing the digital economy. The aim of the article is to substantiate the concept of sustainable development of enterprises in the context of digital transformations. The theoretical and methodological foundations of sustainable development at different levels of the hierarchy have been determined. The concept of sustainable development of enterprises has been developed, the implementation of which is aimed at harmonizing the economic, environmental and social activities of the enterprise. The stages of the process of implementing the concept of sustainable development of enterprises are highlighted, providing for the justification of an inert, neutral, progressive or forced vector. Ensuring the implementation of the concept of sustainable development is expected through the use of applied models, in particular, the implementation of a parametric model of joint deployment of enterprise infrastructure with other infrastructure facilities in economic activity, taking into account technical, geographical, organizational and socio-economic factors to strengthen financial stability; building a model for ensuring a balanced balance between economic efficiency and environmental and social responsibility of an enterprise using a mechanism for managing transformation processes in the process of transition to sustainable development in the context of digitalization.

In order to create a sustainable future for the urban environment in s=Smart cities, it is necessary to develop a concept of urban transport, partially reduce the use of traditional transport, primarily cars, as well as the environmental pressure on society, which is essential to move to a sustainable urban future. In the latest discussions on the future of the urban transport system, the quality of the environment, and the possibility of its improvement are discussed, this issue became especially relevant with the onset of the pandemic, when the lockdowns were introduced. The problem of sustainable transport in urban areas has been recognized in academic studies, searching for appropriate models and solutions. The article presents the latest literature review and illustrates the newest trends with several examples. VOS Viewer software has been used to classify the different keywords, according to their co-citation, following clustering techniques. By analyzing the research conducted by other researchers, it has been possible to structure the ecosystem and trends in the Urban Transportation Concept, also mentioning likely future trends. Based on the literature analysis of the Sustainable Urban Transport, the authors of the study found that a large group of researchers deal with technical solutions and innovative business models, while the essential behavioral aspects are examined in less detail. Extensive literature analysis allowed the authors to select several solutions to achieve the transformation towards sustainable transportation in urban areas: new vehicle technologies and their environmental factors' analysis, geographic information systems, the analytic hierarchy process method, the time series analysis of road traffic accidents using multiplicative models, electrification and use of Friedman Analysis of Variance by Ranks, as well as innovations in sharing mobility.

- Abstract
The world is facing several challenges, and the problem of sustainable development is one of the most important. It is worth considering that European countries are playing a significant role as pioneers in building a sustainable world, such as those promises made by signing the Paris Agreement and European Taxonomy. To achieve ambitious targets within sustainable development, a huge amount of capital is necessary, while financial and capital market participants are expected to demonstrate a high level of engagement in the domain of sustainability. Facing growing interest and demand, a relatively new product—the ESG (environmental, social, and governance) investment fund—was introduced. Scientific literature is providing some controversial views regarding the overall evaluation of this product. Therefore, additional research providing different angles would contribute to a better understanding. This study examines European ESG funds in the energy sector, from the perspective of news flows and investors. It is worth noting that the authors use the word "European" to refer to members of the European Union (EU). The paper consists of the following parts. In the introduction, the current state of this issue is discussed. The following section offers a literature review and a news flow analysis that contributes to a deeper understanding of these issues. A description of the methodology applied for the data analysis follows this, and the final section presents the research results and conclusions. The authors apply statistical analysis and the Carhart model to determine the differences in the performance of the ESG and conventional funds and use their own tool for text analysis to examine the relevance of the topic of ESG to attract client interest. The authors claim that the performance of the European ESG equity funds do not show a statistically significant difference from the non-ESG equity funds in the majority of the periods examined. The application of the adjusted Carhart model demonstrates that the factor of sustainability has a non-significant and negative effect on the fund performance. Finally, the authors highlight the urgent necessity for the unified usage of keywords and terminology, such as "ESG", "sustainability", etc., to ensure comparison and attribution possibilities.

Byline: Dzineta Dimante, Dzintra Atstaja Economic activity has an impact on the environment, but the potential degree of this impact will depend on several factors which are mainly determined by the technology used. This paper analyses the potential environmental impact the economies of the Baltic Sea Region have on their respective countries. The Baltic Sea Region countries are characterised by two economic development scenarios, namely, market and transition economies. Income levels, applied technologies and environmental management practices in these countries differ considerably, and affect a variety of complex indices. These are used to evaluate a country's overall environmental situation and the well being of its inhabitants. An examination of the Baltic Sea Region indicates that high income levels and a stable development path in the 'old' EU member states can provide the grounds for technological advancement to reduce environmental impact. The Baltic Sea and good neighbouring relations serve as a common resource and as facilitators for active cooperation in environmental issues in the region.

Changing business models is a topical issue in a pandemic. Recent research has shown that the search for environmentally friendly and sustainable solutions in various sectors has become relevant. The article aims to promote cooperation and adaptation of good practices between countries. Comparing the country's history and economic situation and economic development and traditions can be seen as a precondition for success. The article examines the introduction of sharing economy and the creation of environment-friendly trends establishing a circular economy by minimizing the population's expenses, online business growth, and accessibility of Internet technologies. The article explores the difference between the linear economic model and the circular model by adopting sharing and the efficient joint use of materials to enhance and assess sustainable development. Based on a combination of theoretical and practical research, the article explores the dynamic system and development model of sharing a circular economy. The new concept of circular economy does not promote the overproduction of new goods but the rational use of already produced ones, which significantly reduces the amount of waste generated at all stages of the product life cycle. Population groups by different income groups for sharing services are analysed. An analysis of the price characteristics of popular sharing products was used from data from Internet portals. One concludes that due to the increase in Internet users, especially mobile apps, and social networks, C2C sharing has become quite popular over the past years. Other areas also show positive development indicators but have less demand, affecting supply. Based on an in-depth study of the economic situation in Ukraine, the authors have critically chosen an industry to set as an example with the actual business situation. Therefore, three packages were created: pessimistic, standard and optimistic ones with different characteristics of implementing circular economic projects. The chosen method allows rational management decisions for attracting financing and sustainable solutions. The company's business scenarios analysed in the article will allow to choose a system based on circular economy principles successfully. [ABSTRACT FROM AUTHOR]

The COVID-19 pandemic has been one of the most unprecedented crises of recent decades with a global effect on society and the economy. It has triggered changes in the behavior and consumption patterns of both final consumer and industrial consumers. The consumption patterns of industrial consumers are also influenced by changes in consumer values, environmental regulations, and technological developments. One of the technological highlights of the last decade is biocomposite materials being increasingly used by the packaging industry. The pandemic has highlighted the problems and challenges of the development of biocomposites to adapt to new market conditions. This study aims to investigate the industrial consumption of biocomposite materials and the influence of the COVID-19 pandemic on the main stages of the value chain of sustainable industrial consumption of biocomposites. The research results reveal there is a growing interest in the use of biocomposites. Suppliers and processors of raw materials are being encouraged to optimize and adapt cleaner production processes in the sustainable transition pathway. The study highlights the positive impact of COVID-19 on the feedstock production, raw material processing, and packaging manufacturing stages of the value chain as well as the neutral impact on the product manufacturing stage and negative impact on the retail stage. The companies willing to move toward the sustainable industrial chain have to incorporate economic, environmental, social, stakeholder, volunteer, resilience, and long-term directions within their strategies.

- Abstract
The latest studies reveal that the COVID-19 pandemic has pushed investors in developed economies to focus more on the value attached to environmental and social responsibilities. Unfortunately, socially responsible investment and compliance with environmental, social and governance criteria are not given enough priority in Latvia at present. The purpose of the study is to investigate how the COVID-19 pandemic has influenced the willingness of Latvians to invest in assets that meet environmental, social and governance (ESG) criteria and factors influencing investors' choice based on their financial literacy. Different views on sustainable investments, socially responsible investments and the relevance of environmental, social and governance criteria from private investors' perspectives were analyzed to identify factors influencing investment decisions in favour of sustainable investments. Quantitative analysis was carried out to reveal the regularities between financial literacy, the willingness to invest to meet the ESG criteria and the level of education and income of the Latvian population, as well as their savings/investment experience. Such statistical methods as descriptive statistics and hypothesis testing were applied to perform an analysis of the results. The authors' findings include the importance of sustainable investing to Latvian society, changes of attitude towards ESG investing in different private investors' groups under the COVID-19 crisis, and the effects of these changes on the financial well-being of the population and, on the basis of these findings, have come to the conclusion that the willingness to invest in the assets that follow environmental, social and governance criteria depends on the level of education, savings/investment experience and income level.

- Abstract
The overwhelming goal of large-scale cross-country research is to evaluate consumers' perception of a sharing economy. The research was limited by the number of respondents, as well as by the countries represented in the survey. Latvia, Russia, Ukraine, and Belarus were mostly represented, and only these responses (757) were analyzed. The study used multilevel modelling of sharing economy elements (dependent variable) in relation to personal characteristics (age, gender, income, industry) nested by the self-assessed level of eco-friendliness (a key predictor for the attitude towards sharing economy). Findings: The key personal characteristics, which influence a person's intention to be involved in the sharing economy practices, are level of income, education, and also self-perceived ecological friendliness. The sharing economy is not only a topic for investigation among academicians, but also an issue on the agenda of the European Commission, because it is considered as a driver for growth and job creation in the European Union. Despite an increasing interest and many studies, there is a limited number of studies focused on difference in perception of sharing economy depending on personal characteristics of respondents. This indicates the necessity of conducting such surveys, involving participants from different European countries. The given paper could be used as a methodological framework for other European researchers who are interested in the exploration of the topic regarding perception of the sharing economy.

- Abstract
Mobility, its current state and development perspectives in the future creates challenges with respect to sustainability, the first of which is the uncontrolled increase in greenhouse gas emissions in the last few decades, while road transport is one of the "sinners" creating long-term negative impact. The second is the dominance of car travel and car usage in the passenger transportation segment before the latest COVID-19 pandemic accelerated environmental problems. Although recent trends show new, greener patterns in consumption, there is still a relatively low share of consumers acknowledging the importance of sustainable and green preferences. This research study aims to investigate car sharing from users' perspectives and to determine the most significant factors influencing their choice of sharing services to ensure upscaling of car sharing and, thus, contribute to urban sustainability. This research study contributes to the overall scientific discussion on car sharing and its role within urban sustainability, particularly with the following: (1) deeper investigation of car sharing and its users motivation perspectives in Latvia; (2) analyses of the most significant motivational factors for car-sharing users and aspects of sustainability; and (3) the insight into the generational differences triggering a number of car-sharing users. The existing and potential users of car sharing were surveyed in order to determine the motivational factors for its usage and attitudes towards it. Socio-demographic variables in statistical analysis were used to identify economic and environmental factors that meaningfully influence the choice of car-sharing services. The results of this study can support further development in new car-sharing business models and the value proposition for consumers in Latvia, as well as preparing policy recommendations on the promotion of sustainable transport. These findings are also useful to academics for the investigation of recent trends in car sharing during the COVID-19 pandemic. [ABSTRACT FROM AUTHOR]

- Abstract
This article provides a practical example of the development of cross-border tourism and its link to achieving sustainable development goals. Greenways (GWs) are successful and recognized initiatives in Western Europe, but have recently also shown development trends in Eastern Europe, notably, in the Baltic Sea Region and Russia. These initiatives improve the quality of life and provide opportunities for sustainable economic activities for the local communities, especially in rural areas, adding value to their natural, cultural, historical and human heritage. The authors studied examples of best practice in scientific literature and practice, encouraging the development of cross-border tourism and GWs in Europe and Russia, in order to further adapt it to other continents. Analyzing the environmental, economic, social and institutional factors in the region and their role in sustainable development, the need for institutional regulation that would allow the development of a wider development of GWs is identified. Research results reveal sustainable development dilemmas of positive socioeconomic effects of GWs and negative environmental effects of increased flows of tourists. Focus groups and expert interviews allowed us to assess the level of various factors contributing to sustainable development and clarify the directions of the future research. [ABSTRACT FROM AUTHOR]
