Oily wastewater from agro-industries can cause severe environmental and public health damages if unproperly treated. The conventional methods have several limitations for the treatment of oily wastewaters since the oil fraction can cause pipe clogging and biomass washout during the biological step. Based on this, the use of lipases can increase the oil removal efficiency of the treatments, minimizing operational problems,and improving the performance of the biological process. Lipases can also be used for the valorization of the oily wastewaters, transforming these waste streams intovaluable compounds, such as biodiesel, lubricants, antioxidant agents, etc. The use of wastes for the production of value-added compounds followsthe circular economy approach, minimizing the generation of residues and potential environmental liabilities. Thus, this study aims to give a general overview of themain topics related to thetreatment and valorization of oily wastewaters using lipases. The main characteristics of oily wastewaters from agro-industries areaddressed, as well as the most used conventional techniques for their treatment. Some relevant information about the enzyme lipaseisalso discussed to give the reader a background about how these enzymes can be applied for the treatment and transformation of oily wastes.

Abstract Public health professionals (PHP) have a dual task in climate change. They should persuade their colleagues in clinical medicine of the importance of all the issues covered by the GD. The fact that the health sector contributes to the overall emissions of 4.4% speaks to the lack of awareness within the health sector itself. The issue of providing adequate infrastructure for the health sector is essential. Strengthening the opportunities and development of the circular economy within healthcare is more than just a current issue. The second task of PHP is targeting the broader population. The public health mission is being implemented, inter alia, through numerous activities related to environmental monitoring and assessment of the impact on health. GD should be a roadmap for priorities and actions in public health, bearing in mind: an ambitious goal of climate neutrality, an insistence on clean, affordable and safe energy, a strategy for a clean and circular economy. GD provides a framework for the development of sustainable and smart transport, the development of green agriculture and policies from field to table. It also insists on biodiversity conservation and protection actions. The pursuit of zero pollution and an environment free of toxic chemicals, as well as incorporating sustainability into all policies, is also an indispensable part of GD. GD represents a leadership step in the global framework towards a healthier future and comprises all the non-EU members as well. The public health sector should consider the GD as an argument for achieving goals at national levels, and align national public health policies with the goals of this document. There is a need for stronger advocacy of health and public-health interests along with incorporating sustainability into all policies. Achieving goals requires the education process for healthcare professionals covering all of topics of climate change, energy and air pollution to a much greater extent than before.

Abstract The national response for reducing lead (Pb) exposure in Georgia is coordinated by the National Centre for Disease Control and Public Health (NCDC&PH) and implemented as a multi-agency (CDC, UNICEF, WHO, University of Emory) response. Given concerns about the extent of Pb exposure, in 2018 Multiple Indicator Cluster Surveys (MICS) of representative samples of children have been conducted to study several demographic and health aspects, including a study of the prevalence of blood Pb levels among 2 to 7 years old children (n = 1578). This survey was conducted in collaboration with the Italian Instituto Superiore di Sanita' (ISS), UNICEF and NCDC. The laboratory analyses were conducted at ISS in Italy. Initial results showed that in 41% of all children, blood Pb concentration was ≥ 5 µg/dl, a challenge which motivated public agencies to establish an initial public health action plan to assess environmental samples (paint, dust, water, soil, selected food items such as spices and imported sweets) in families where Pb concentrations were ≥ 10 µg/dL. A State intervention programme, monitoring Pb blood concentration among MICS children and their family members, provided relevant information on exposed households and led to a reduction of Pb blood concentration across the most exposed households. In collaboration with Public Health England, NCDC has conducted a small Pb isotope ratio study aimed at identifying the most relevant sources of Pb exposure contributing to elevated blood Pb in MICS children. It is expected that these data will support the design of more detailed public health interventions to reduce exposure to key sources of Pb, thus leading to further reduction of Pb-induced health effects in Georgia. In addition, this experience will clarify elements of an ongoing monitoring of environmental factors such as an Environmental Public Health Tracking system, to support national capacity to manage the risks to public health. Key messages Environmental health response requires extensive research and multi-agency approach. If State implements adequate intervention it is possible to reduce blood lead (Pb) level.

Multilevel statistical entropy analysis (SEA) is a method that has been recently proposed to evaluate circular economy strategies on the material, component and product levels to identify critical stages of resource and functionality losses. However, the comparison of technological alternatives may be difficult, and equal entropies do not necessarily correspond with equal recyclability. A coupling with energy consumption aspects is strongly recommended but largely lacking. The aim of this paper is to improve the multilevel SEA method to reliably assess the recyclability of plastics. Therefore, the multilevel SEA method is first applied to a conceptual case study of a fictitious bag filled with plastics, and the possibilities and limitations of the method are highlighted. Subsequently, it is proposed to extend the method with the computation of the relative decomposition energies of components and products. Finally, two recyclability metrics are proposed. A plastic waste collection bag filled with plastic bottles is used as a case study to illustrate the potential of the developed extended multilevel SEA method. The proposed extension allows us to estimate the recyclability of plastics. In future work, this method will be refined and other potential extensions will be studied together with applications to real-life plastic products and plastic waste streams.

The purpose of the study presented in this text is to show the influence of COVID-19 on waste management systems and circular economy stream, and their impact on circular economy, particularly the economic impact of the pandemic on the waste management sector, impact on circular economy objectives’ implementation as well as additional challenges like the need for hygienization of waste streams during different implementation efforts, such as changes in the municipal solid waste market and different waste processes of their disposal. Additionally, some methods—such as thermal treatment—which seemed to be not fully aligned with the circular economy approach have advantages not taken into account before. Incineration of higher volume of waste affects the waste structure and will change some of the circular economy objectives. The analysis was carried out on the example of the Polish market.

Circular Economy is the solution for the current environmental crisis, representing a huge economic opportunity to build new sustainable businesses. However, many barriers need to be faced for its implementation at industrial scale—firstly, the lack of data sharing between the different stakeholders of product value-chains. The DigiPrime project is an EU-funded Innovation Action aimed at developing and demonstrating a digital platform with services able to unlock innovative cross-sectorial business models for the remanufacturing and recycling of target value-added products. In this paper, the concept behind the DigiPrime project is reported, with a particular focus on the construction sector.

Paradoxical Situation

In this paper I analytically review the literature on the information overload problem, with special reference to the business organizations and entrepreneurship and the study mainly reveals that the problem of the information overload has been existed for many years, whereas in current years the problem has become more clearly recognized and experienced. A concern stressed in the literature is the paradoxical situation that most probably there is an abundance of information available and it is often difficult to obtain useful, and relevant information when it may be needed. Both perceptions and the actual effects of information overload have exacerbated by rapid advances made in the information and communication technology, whereas it is not clear cut as to whether Internet has worsened/improved the situation. Some solutions have put forward to reduce the information overload are a reduction in duplication of the information found in professional literature; the adoption of the personal information management strategies, along with the integration of software solutions such as push technology and intelligent agents; and the provision of value-added information. Main emphasis is placed on the technology as a tool and not driver, while increased in information literacy may provide key to reducing the information overload in organisations.

Research background: Consumers’ interest in environmental responsibility, sustainable consumption, and the circular economy is significantly increasing in all aspects of their lives. Clothing and fashion are clearly among these aspects. The fashion industry is one of the most resource-intensive and environmentally polluting industries. Circularity has been offered as a solution to this issue; however, the change must be in the attitudes of all concerned (Musova et al., 2021b). Businesses must react to this requirement for sustainable fashion, which is the reason that new circular concepts have been raised. Different generations prefer different models of circularity. Purpose of the article: The purpose of the current study is to detect the existence of dependency between generation and the fashion industry’s circular models, and to identify consumers’ specific preferences. Methods: The original consumer survey was undertaken by the authors in 2021, and involved 513 Slovak and 974 Czech consumers, who responded on their preferences in the circular economy. Pearson’s chi-square test of independence was used to confirm the dependence between consumers’ generation and the circular concept. The significant medium dependence of the nominal variables was confirmed by Pearson’s contingency coefficient, C, and Cramer's V. The relationships between the generation categories of Central European consumers and the categories of the new circular models in the fashion industry were established through correspondence analysis. Findings & Value added: The findings of the study suggest that Baby boomers single out capsule wardrobes, Generation X prefers patchwork and slow fashion, while Millennials prioritise GOTS and SWAP. Finally, Generation Z favours leasing jeans, upcycling, and renting clothes.
