Ecological Analysis of Technology Use Among Children in Collaborative Design Contexts

ABSTRACTBackgroundIn this paper, we extend findings from previous iterations of a design‐based project called ThinkerSpaces design studios that promotes human‐centred design among children. ThinkerSpaces design studios is a play‐based afterschool club that follows principles of embedded design by prioritising learner agency, exploration and ongoing reflection for the purpose of improvement.MethodsIn this study, we wanted to examine the difference in collaborative interactions across different technological conditions and the learning outcomes these conditions provided. Thus, we created three comparative technology conditions, that is, physical, screen and mixed technologies, each of which represented a collaborative learning environment dominated by a particular kind of technology. We ran three different sections of the club to vary these technology conditions and control when we introduced them. We use a mixed‐methods approach to analyse the data and capture distinct aspects of the learning ecology to understand the following questions: (RQ1) How do collaborative interactions differ as young learners engage with different technologies; and (RQ2) What does productive and unproductive talk looked like across conditions and what learning opportunities do they provide. Our population included 36 third to seventh grade learners enrolled across three club section. Learners were placed into four triads in each section for a period of 14–18 weeks.FindingsWe found that physical technologies produced the most productive talk, followed by the mixed technology condition. Screen‐based technologies produced the most unproductive talk. However, when we further investigated unproductive talk, we discovered that unproductive talk supported different forms of agency and creativity that facilitated learners' ability to develop digital fluency. Students also learned how to regulate collaborative activity around technology. We use these findings to propose changes in technology integration approaches in teaching and learning.ContributionWe end the paper by proposing a collective technology integration framework that helps facilitators design learning environments that promote learner agency in the process of technology integration.

Integrating one health with indigenous knowledge for improving public wellbeing – a review

PurposeThe interconnection between humans and animal has raised the concept of one health (OH) framework. The framework works at local, regional, national and global level with the aim to improve public health. However, while covering the OH approach, the knowledge of indigenous communities has not been given much attention. Despite of the fact that indigenous communities are living closely to ecosystem, their exceptional knowledge on OH has not been utilised. The present study has reviewed different studies to explore the prominent role of indigenous knowledge between the relationship of OH framework and public wellbeing.Design/methodology/approachThe present study is a narrative review which has included different quantitative and qualitative studies conducted in the area of OH field in concern to public health and indigenous knowledge. The present study has included the literature which is published in English language from the year 2001–2024 conducted in developed and developing countries.FindingsOn the basis of prevailing literature in the area, the present study has framed a model to integrate the OH with indigenous knowledge to improve public health. The model explains the concept of public wellbeing which is deeply rooted in the knowledge of indigenous communities associated with animal and veterinary care, ecological aspect, culture, religion, language, healing and wellness, food and nutrition practices.Research limitations/implicationsAfter considering the literature prevailing in concern to OH, it has been determined that OH approach is more prominent in scientific environment and laboratory equipment. The discipline of OH requires an inclusion from the researchers of social sciences and various behavioural fields. The present study has offered different factors which may act as an entry point for researchers to explore the field. Further, the study has suggested validating a comprehensive model offered by present study in empirical manner to improve public health.Originality/valueThe present study has highlighted the relevance of indigenous knowledge for promoting OH principles in public wellbeing. Also, the study has offered a model which can be utilised by future researchers to explore the relationship between OH, indigenous knowledge and public wellbeing.

Conviviality: our primary connectedness to living beings

Abstract In the ecological discourse on nature and the environment, the natural side of humans, which we experience as our own corporeality, plays hardly any role. To address this deficiency, the paper proposes the concept of conviviality. It refers to a primary connection with the living environment, conveyed through our own sense of aliveness and embodiment. The concept encompasses three interconnected aspects: 1) An epistemological aspect, according to which we can only recognize other living beings as such and distinguish them from inanimate things through the experience of our shared bodily existence; 2) A natural-philosophical and ecological aspect, which relates to the fundamental interdependence of all living beings and the interpenetration of life and the environment; 3) An ethical aspect, where our kinship and connection with living beings form the basis for an attitude of care and commitment towards them. The three aspects are based on the same fundamental structure, namely the interdependence of the living, both in subjective, phenomenal terms, and in objective, ecological terms. At the same time, they are grounded in our corporeality, which points to the relational nature of our existence, our life in relationships and in ecological contexts. In this way, the fundamental kinship of our lived bodies with living nature becomes the basis for an ecological ethic.

Strengthening the evidence for seasonal intertidal exploitation in Mesolithic Europe and new insights into Early Holocene environmental conditions in the Bay of Biscay from the oxygen isotope composition of Phorcus lineatus (da Costa, 1778) shells

Marine molluscs have been exploited by human societies since prehistoric times. Such practices have often resulted in large accumulations of shell remains in archaeological sites that offer unique information on biological, ecological and cultural aspects of human interaction with coastal systems in the past. In this study, stable oxygen isotope (δ18O) analysis was carried out on archaeological shells of Phorcus lineatus (da Costa, 1778) from the Mesolithic shell midden site of J3 (northern Iberian coast) to determine the seasonality of intertidal collection. The results indicate a consistent pattern of winter exploitation, supporting the emerging view that collections were governed by cost-benefit and management principles that are now widespread documented in other coastal Mesolithic sites in Europe. The consistent seasonal collections of P. lineatus during colder months can be taken as evidence of specie-specific management strategy to optimize yield while preserving local populations for future exploitation. Our results reinforce the view that European hunter-gatherers developed ecological knowledge on specific animal resources that persisted over large geographic areas. Additionally, from a palaeoenvironmental perspective, the sea surface temperatures (SST) inferred from δ18O values derived from mollusc shells (SSTδ18O) indicate that coastal marine waters during the Early Holocene in the southern Bay of Biscay were warmer than those of today. These environmental conditions are evaluated in relation to changes in insolation and ocean currents over time.

<b>Ontología del paisaje</b><b></b>

The article explores, from an onto-poetic perspective the deep connection between the human being and the landscape, arguing that both are interdependent and influence each other. From a sentimentalized perspective it explores how landscape is not only a physical context in which we live, but also an integral part of our existence and spirituality. Through poetic narrative we explore diverse cultural traditions, such as the Quechua, and examine how landscape has been perceived and valued throughout history. At the same time, the article addresses the transformation of the landscape and its impact on humanity, as well as the responsibility of human beings in its conservation and restoration. It emphasizes the need for an integral understanding of landscape that includes ecological, spiritual and cultural aspects. In addition, a critical reflection on the exploitation of the environment and the importance of adopting an attitude of care and respect towards nature is proposed.

Commodity Zoning and Identification of Agricultural Practices Using an Agroecological Approach in Selur Village

Selur Village is an agrarian village where most residents rely on the agricultural sector as their primary source of livelihood. However, this sector faces challenges such as limited irrigation access, suboptimal land management, and the impacts of climate change. Agroecology offers an integrative solution combining ecological, social, and cultural aspects to enhance agricultural sustainability. This study aims to delineate superior commodity zoning through agroecological maps tailored to the biophysical potential of the area and to understand local farming practices based on agroecological principles. The research employs a mixed-method approach, with primary data obtained through interviews with 18 farmers, analyzed using Deductive Qualitative Analysis (DQA) to describe current farming practices, which were then interpreted about agroecological principles. Secondary data, including slope, elevation, air temperature, rainfall, and soil type, were spatially analyzed using QGIS to produce agroecological zone maps. Land suitability assessment was conducted using the matching method, aligning land characteristics with crop growth requirements. The results indicate that the majority of land in Selur village is suitable for perennial crops and forestry. Key commodities such as rice, maize, turmeric, and horticultural crops exhibit high compatibility with land conditions. The findings emphasize the application of agroecological principles, including crop diversification, soil conservation, and resource recycling, but highlight the need for further interventions. The study concludes by recommending strategies such as sustainable intensification, land rehabilitation, and enhanced market access to optimize agricultural productivity and resilience in Selur Village.

A Systematic Literature Review of Water-Sensitive Urban Design and Flood Risk Management in Contexts of Strategic Urban Sustainability Planning

Despite various sustainable urban development frameworks, over the years, inadequate land use patterns and infrastructure have worsened existing problems related to climate disasters such as flooding, heavy precipitation and droughts. Based on a systematic PRISMA literature search and bibliographic analysis, we analyzed statistical data from 44 articles relevant to water-sensitive urban design (WSUD) and flood risk management (FRM) worldwide from 2013 to 2023. We focused on specific selection criteria that focused on settlement typologies and outcomes, indicators and planning approaches to analyze the impact of flooding on urban infrastructure of four different settlement types in 23 case studies, summarized into nine different approaches. The results show that WSUD and FRM have shared sustainability goals but differ in their focus and applicability depending on the settlement type and indicators. In the context of strategic planning for urban sustainability, it can be stated that WSUD has a much stronger focus on integration and future orientation than FRM. Therefore, WSUD seems better suited to be linked to strategic planning for urban sustainability than FRM. Finally, we propose to extend WSUD to “water-sensitive regional design (WSRD)”. This broader framework would integrate regional hydrological, ecological and socioeconomic aspects to address water issues at a larger scale.

Spatial Model of Carbon Stocks in Special Purpose Forest Area (KHDTK) Mungku Baru, Central Kalimantan Province, Indonesia

This study aims to estimate vegetation biomass and spatial distribution of carbon stocks in Special Purpose Forest Area (KHDTK) Mungku Baru, Palangka Raya City, Central Kalimantan Province, Indonesia. KHDTK Mungku Baru is a former logging area from the 1970s, which has undergone secondary succession and is dominated by pole and sapling levels. The approach used in this study involves remote sensing technology and field inventory data, which allows carbon stock calculations to be carried out quickly and accurately over a very large area. A linear regression algorithm was used to obtain a spatial model of carbon stocks using NDVI obtained from Landsat as a predictor. The developed model shows positive correlation results with an R2 value of 0.70; an Adjusted R2 value of 0.69 with a p-level < 0.05, and RMSE of 42 tons/ha. This carbon stock mapping results serve as a basis for formulating various management plans for KHDTK Mungku Baru regarding ecological, social, and economic aspects. Keywords: carbon stocks, normalized difference vegetation index, spatial model, special purpose forest area, vegetation biomass

A review and redefinition of the subgenus Aphyobranchius Wildekamp, 1977, in the seasonal killifish genus Nothobranchius Peters, 1868 (Teleostei: Nothobranchiidae), from ephemeral wetlands of eastern Tanzania

Species belonging to the subgenus Aphyobranchius, of the seasonal killifish genus Nothobranchius, are reviewed and the definition of the subgenus is updated. Five species are recognized within this subgenus which, based primarily on morphological and molecular data, form two distinct groups: N. geminus, N. janpapi and N. luekei make up the N. janpapi species group, whereas N. fuscotaeniatus and N. lourensi comprise the N. lourensi species group. All known Aphyobranchius species occur in the central eastern and southern coastal plains region of Tanzania, associated mainly with the Ruvu, Rufiji, Kilombero, Mbezi and Luhule/Luhute river systems, with isolated occurrences in the lowermost reaches of the Wami and Matandu rivers. Features that allow distinction between the five Aphyobranchius species, as well as those that in a broader sense distinguish them from other Nothobranchius species, are documented in detail. Such features primarily comprise differences in elements of colour pattern, morphometric character, phylogenetic relationships, karyotype structure, habitat characteristics and niche preference, breeding behaviour and, to some extent, distribution. We further discuss the taxonomic, biogeographic, ecological and evolutionary aspects of the subgenus. Conservation status of the species range from Least Concern to Critically Endangered, according to IUCN Red List criteria. The main threats to their survival are habitat loss due to expansion of agriculture and urbanisation involving overexploitation of wetlands, and invasive species. Nothobranchius willerti, previously regarded as a member of Aphyobranchius, is here excluded from that subgenus, based on a reassessment of key morphological characters, habitat preference, breeding behaviour and, most importantly, molecular data that indicates a clear affiliation with other species of the subgenus Adiniops.

Relationship Between the Host Plant Range of Insects and Symbiont Bacteria.

The evolution of phytophagous insects has resulted in the development of feeding specializations that are unique to this group. The majority of current research on insect palatability has concentrated on aspects of ecology and biology, with relatively little attention paid to the role of insect gut symbiotic bacteria. Symbiont bacteria have a close relationship with their insect hosts and perform a range of functions. This research aimed to investigate the relationship between insect host plant range and gut symbiotic bacteria. A synthesis of the extant literature on the intestinal commensal bacteria of monophagous, oligophagous, and polyphagous tephritids revealed no evidence of a positive correlation between the plant host range and the diversity of larval intestinal microbial species. The gut symbionts of same species were observed to exhibit discrepancies between different literature sources, which were attributed to variations in multiple environmental factors. However, following beta diversity analysis, monophagy demonstrated the lowest level of variation in intestinal commensal bacteria, while polyphagous tephritids exhibited the greatest variation in intestinal commensal bacteria community variation. In light of these findings, this study proposes the hypothesis that exclusive or closely related plant hosts provide monophagy and oligophagy with a stable core colony over long evolutionary periods. The core flora is closely associated with host adaptations in monophagous and oligophagous tephritids, including nutritional and detoxification functions. This is in contrast to polyphagy, whose dominant colony varies in different environments. Our hypothesis requires further refinement of the data on the gut commensal bacteria of monophagy and oligophagy as the number of species and samples is currently limited.

Techniques for Evaluating Airborne BiocrustDiaspores: From Fundamentals to Advanced Approaches

Biological soil crusts (biocrusts) are communities which thrive primarily in the upper soil layers of arid and semi-arid environments. Biocrusts produce soil-binding compounds, tolerate extreme conditions, and disperse through both sexual and asexual diaspores via wind, water, or animals. Despite their significance, dispersal mechanisms involving airborne diaspores in biocrusts remain largely unexplored and poorly understood. This review provides an overview of techniques, from basic to advanced, to help researchers investigate these often-overlooked aspects of biocrust ecology. We discuss both passive and active methods for sampling airborne organisms, highlighting their potential in studies of biocrust organisms. We present traditional techniques, such as microscope glass slides coated with adhesive substances, as well as more advanced equipment like Rotorods. For organism identification, we explore traditional morphological methods, but also introduce more modern approaches, such as metabarcoding, which allow for the simultaneous study of multiple organism groups. This review underscores the potential of these methods to enhance our understanding of the aerobiology of biocrusts. By shedding light on these dispersal dynamics, this review aims to support future research and foster advancements in biogeography, ecosystem restoration, and conservation strategies.

Fit for the Future: An Assessment of the Sustainability Parameters of Liquid Dairy Product Packaging in the DACH Region and the Implications of Upcoming Regulatory Changes.

The European Union aims for climate neutrality by 2050 and has proposed the Packaging and Packing Waste Regulation (PPWR) to promote a circular economy, focusing on reducing packaging waste. In this context, a comprehensive sustainability assessment for liquid dairy product packaging, including beverage cartons, bottles and to-go cups, in the DACH region (Germany, Austria and Switzerland) was conducted. The aim was to consider various ecological aspects of environmental impacts and circularity. As the aspect of recyclability is a core aspect in the PPWR, the calculation was of central interest in this project. Here, major differences in the waste management infrastructure between countries could be identified. The majority of assessed packaging falls below the PPWR's 70% recyclability requirement, with Switzerland showing even lower recyclability due to poor packaging collection and recycling infrastructure. Significant discrepancies in packaging efficiency exist, indicating unnecessary resource consumption, especially in the case of to-go cups. Additionally, the carbon footprint of packaging materials can vary up to ten times within certain product categories, negatively impacting the environment. Good results were identified for the use of certified renewable resources. Overall, the results of the assessment demonstrate several areas for improvement in light of forthcoming regulatory requirements, which must be met in Germany and Austria.

Molecular Phylogenetics and Estimation of Evolutionary Divergence and Biogeography of the Family Cordycipitaceae (Ascomycota, Hypocreales).

The Cordycipitaceae family of insecticidal fungi is widely distributed in nature, is the most complex in the order Hypocreales (Ascomycota), with members displaying a diversity of morphological characteristics and insect host ranges. Based on Bayesian evolutionary analysis of five genomic loci(the small subunit of ribosomal RNA (SSU) gene, the large subunit of ribosomal RNA (LSU) gene, the translation elongation factor 1-α (tef1-α) gene, the largest subunit of RNA polymerase II (rpb1), and the second largest subunit of RNA polymerase II (rpb2), we inferred the divergence times for members of the Cordycipitaceae, improving the internal phylogeny of this fungal family. Molecular clock analyses indicate that the ancestor of Akanthomyces sensu lato occurred in the Paleogene period (34.57 Mya, 95% HPD: 31.41-37.67 Mya), and that most species appeared in the Neogene period. The historical biogeography of Akanthomyces sensu lato was reconstructed using reconstructing ancestral state in phylogenies (RASP) analysis, indicating that it most likely originated in Asia. Combined morphological characterization and phylogenetic analyses were used to identify and taxonomically place five species within Cordycipitaceae. These include the following: (i) two new species, namely Akanthomyces baishanensis sp. nov. and Samsoniella sanmingense sp. nov., (ii) a new record species isolated from infected Lepidopteran host, Blackwellomyces lateris, (iii) a new record species in the genus Niveomyces, with sporothrix-like asexual morphs, namely N. multisynnematus, isolated from dipteran insects (flies), and (iv) a known species of the (hyper-) mycoparasite, Liangia sinensis, isolated from the fungus Ophiocordyceps globiceps (Ophiocordycipitaceae) growing on a dipteran host. Our data provide a significant addition to the diversity, ecology, and evolutionary aspects of the Cordycipitaceae.

Sustainability and lives of coffee farmers in Magetan Regency, East Java, Indonesia

The lack of knowledge of farmers about efforts to manage coffee plantations with environmental and conservation views is believed to have the effects of microclimate change which are likely to impact coffee farmers in the future. The purpose of the research is to (1) identify ecological aspects on the sustainability of coffee cultivation patterns in the Magetan region, (2) find ecological factors on coffee production, and (3) describe the lives of coffee farmers related to ecological aspects. The research method was carried out by a multistage sampling method starting from the determination of subdistricts, villages, farmer groups, farmer group members, and coffee farmer samples. The data used are primary data, with a method of collecting direct survey data on 80 coffee farmers randomly in two districts of Panekan and Poncol. An analysis method to see the relationship of environmental variables to coffee production with multiple linear regression analysis and descriptive analysis for ecological aspects. he results showed that the ecological factors significantly affecting coffee production included the number of protective trees, the application of manure, and farmers' knowledge of conservation practices. Conversely, pruning and the eradication of coffee borer pests were found to have an insignificant impact. The study concludes that while efforts toward coffee sustainability have been initiated by farmers, they have not yet achieved full success. Sustainability efforts include protecting the environment through the use of manure, planting shade trees, and adopting conservation-oriented coffee cultivation practices.

A framework to evaluate public green spaces with an emphasis on recreational values for sustainable urban and rural areas: A systematic review and content analysis.

Though numerous studies acknowledge the critical role played by green spaces (GS) in bolstering sustainability in various dimensions, a majority of these investigations primarily center on the ecological aspect and urban environments. Due to the multifaceted benefits of GSs, different categories and expectations of these spaces can be identified across disciplines. Hence, no single method exists for evaluating the success of GSs in promoting sustainability due to the multifaceted benefits and variety of expectations. This study provides a framework for evaluating public green spaces (PGS) holistically based on sustainability discourse, specifically including rural and transitional rural-urban areas, with a focus on GS's recreational values. Employing a systematic review of 130 publications sourced from Web of Science, Scopus, and Google Scholar and ensuing content analysis, we identified and elaborated on 14 distinct qualities, including accessibility, connectedness, responsiveness, variety of activity, social interactions, facilities, safety and security, spaciousness, biodiversity, perceptual value, aesthetic value, and symbolic value. The interrelationships among these identified qualities are also elucidated through the content analysis. These qualities can be utilized as a novel approach to evaluate the efficiency of PGSs in promoting sustainability.

SUBAK: Traditional ecological knowledge for sustainable biodiversity conservation

Abstract Subak is a customary law community with socio-agrarian-religious characteristics, a collection of farmers managing water in rice fields. Nevertheless, Bali’s intense tourism pressures have significantly changed the agricultural system. This study aims to document Subak’s traditional ecological knowledge (TEK) of sustainable biodiversity conservation. This research uses the literature method that emphasizes literature as an object of study. Data on Subak was collected from various online publication sources using several keywords, including ‘Subak’, traditional ecological knowledge’, ‘biodiversity’, ‘conservation’, ‘Tri Hita Karana’, and ‘ecotone’. Descriptive analysis through an ethnosystems approach is used as the main approach to examine the interdependence relationship between certain groups of ethnic and their perspective on nature. The results of the study have documented Subak’s TEK about biodiversity conservation contained in the Tri Hita Karana philosophy through three aspects, namely the spiritual aspect (Parahyangan), the social aspect (Pawongan), and the ecological aspect (Palemahan). The implementation of Parahyangan aspect is reflected in respect and responsibility for nature as a manifestation of divine creation, thus viewing nature as a sacred and precious entity. The Pawongan aspect is reflected in strong social cooperation and respect for local knowledge; and ensures that agricultural practices are not only productive but also sustainable and environmentally friendly, as well as contributing to the preservation of biodiversity and ecosystem balance. Meanwhile, Palemahan aspects are reflected through sustainable soil and water management practices, maintenance of native vegetation and natural habitats, as well as ecosystem conservation and restoration efforts. In conclusion, the Subak system with the Tri Hita Karana philosophy can be a unique model for sustainable biodiversity conservation. Biodiversity conservation not only supports ecosystem resilience but also strengthens social and culturalties.

The implementation of Gelintung Go Green Urban Farming is realized through the development of the younger generation, the development of the community’s socio-economic, the Green Business Movement, and the Water Saving Movement. This study concludes that from an economic perspective, Social, and Ecology. The society of Kampung Gelintung Go Green feels that their economy has improved, especially with the implementation of greening until it is realized as Kampung Wisata Gelintung Go Green, the most basic social aspect of its benefits is the increase in interaction between residents in various places.

Reconstructing dinosaur locomotion.

Dinosaur locomotor biomechanics are of major interest. Locomotion of an animal affects many, if not most, aspects of life reconstruction, including behaviour, performance, ecology and appearance. Yet locomotion is one aspect of non-avian dinosaurs that we cannot directly observe. To shed light on how dinosaurs moved, we must draw from multiple sources of evidence. Extant taxa provide the basic principles of locomotion, bracket soft-tissue reconstructions and provide validation data for methods and hypotheses applied to dinosaurs. The skeletal evidence itself can be used directly to reconstruct posture, range of motion and mass (segment and whole-body). Building on skeletal reconstructions, musculoskeletal models inform muscle function and form the basis of simulations to test hypotheses of locomotor performance. Finally, fossilized footprints are our only direct record of motion and can provide important snapshots of extinct animals, shedding light on speed, gait and posture. Building confident reconstructions of dinosaur locomotion requires evidence from all four sources of information. This review explores recent work in these areas, with a methodological focus.

WASTE MANAGEMENT AS AN ELEMENT OF REVERSE LOGISTICS IN THE CIRCULAR ECONOMY

This article examines waste management and recycling as an element of reverse logistics in a circular economy. The concept of circular economy can be found very often in scientific and social environment. The aim of the article is to analyze the trends of waste management and recycling as a reverse logistics element in the conditions of circular economy in Europe and Lithuania. To achieve the goal were done: an analysis of theoretical sources to reveal the essence and connections of reverse logistics and circular economy, analysis of LR and EU legislation, development strategies of the environmental protection and waste management sector, analysis of EUROSTAT statistical data, monitoring, situation assessment and questionnaire survey. The main goals of the circular economy model are less raw materials, less waste, less emissions, managing such elements as raw materials, sustainable design, production, distribution, consumption, reuse, repair, collection, waste management, and residual waste. Direct logistics processes and reverse logistics play really important role in this concept. Logistics examines the movement of material, financial and information flows from the source of raw materials to the end user, reverse logistics examines the same flows, only in the opposite direction. Reuse, repair, collection, waste management are on responsibility of reverse logistics. For this reason, waste management in the terms of a circular economy cannot be seen only as the responsibility of the government and the end user (the resident sorting the waste). All participants in the supply chain, who were interested in bringing the material flow to the end user, and who created added value in the supply chain, according to the "polluter pays" principle, should take responsibility for the waste generated in the country, waste management and sorting, recycling. Because, for example, prevention of waste generation is a priority, and the cheapest solution is to avoid waste management and recycling. Thus, all participants in the supply chain must be interested and cooperate in the implementation of the circular economy. The general trends in the collection of the main sorted waste in Europe and Lithuania are not unambiguous, since waste management is regulated by different local laws of the countries. A general increase in the amount of sorted and collected waste is recorded, but not all countries demonstrate an increase, this may be related to the elements of the circular economy that have already been implemented, public awareness, declining consumerism, the economic situation in the country and other factors that lead to a generally more responsible approach to ecological aspects. EU newcomer countries are characterized by large increase in waste collection, regardless of waste types. Consumer opinion is quite favorable to the implementation of circular economy principles, but the main idea is that most of the responsibility for waste collection and management must be transferred to commercial participants in the supply chain.
