This study examines the potential implications of the EU–Mercosur free trade agreement for the Polish horticultural sector, with particular emphasis on sustainability, trade competitiveness, and structural complementarities between the regions. Drawing on production, trade, and demographic data for the EU, Poland, and Mercosur countries, the analysis evaluates the alignment of horticultural supply and demand structures, the degree of intra-industry exchange, and the economic conditions shaping bilateral trade. The research applies the Grubel–Lloyd index and a Poisson Pseudo-Maximum Likelihood (PPML) gravity model to assess the determinants of Poland’s horticultural exports to Mercosur. The results indicate that trade remains predominantly inter-industry, reflecting substantial differences in agricultural specialisation and regulatory frameworks. At the same time, rising income levels in Mercosur, together with selected product-level complementarities, indicate emerging export opportunities for Poland. Poland’s trade with the Southern Common Market remains mainly as inter-industry, with the greatest export potential concentrated in high-value-added processed goods. Divergent sustainability standards, particularly in pesticide use, environmental regulation, and carbon-intensive transport, pose structural challenges that may affect the competitiveness and environmental footprint of expanded trade. Overall, the findings provide evidence that closer integration with Mercosur may support export diversification, but requires careful alignment with the EU’s sustainability objectives to ensure resilient and environmentally responsible development of the horticultural sector.

The growing demand for sustainable cosmetic products and the rapid expansion of the pet care market have driven the search for environmentally friendly, safe, and effective alternatives to conventional formulations. In this study, an ecofriendly solid shampoo for pets was developed using exclusively natural ingredients and a microbial biosurfactant produced by Starmerella bombicola ATCC 22214 as a surface-active component. The biosurfactant was combined with renewable anionic and nonionic surfactants, conditioning agents, natural oils and butters, and minimal water content to obtain a compact, solid formulation. The shampoo was produced through a controlled multi-phase process and subsequently characterized by physicochemical, microbiological, toxicological, and performance analyses. The formulation exhibited stable pH values suitable for pet skin, low moisture content, absence of free alkalinity, high solid content, and satisfactory foaming capacity. Cleaning efficiency tests demonstrated effective removal of artificial sebum from pet fur while preserving softness and shine. Microbiological assays confirmed the absence of bacterial and fungal contamination, and toxicological evaluations revealed no cytotoxicity and low eye irritation potential. In addition, the shampoo showed 100% biodegradability and maintained physicochemical and organoleptic stability over six months of storage. Overall, the results demonstrate that the developed solid shampoo represents an innovative, safe, and biodegradable alternative that reduces water consumption and plastic packaging, contributing to sustainable development in the pet cosmetics sector.

This exploratory study addresses the problem of limited research on quality assessments of newly emerging multi-use market formats that function as social hubs and their management as privately managed public spaces. Using Āgenskalns Market, a revitalised multi-use market hall in Riga, as a case study, the authors apply an assessment framework based on Yuri Impens’ study on covered food halls, incorporating quality criteria from Vikas Mehta’s Public Space Index and the UN-Habitat’s Site-Specific assessment methodology. Leclercq et al.’s works on privatisation of public spaces are integrated in the analysis of “publicness”. This framework evaluates user and observer perceptions across four dimensions: environmental quality and comfort, accessibility and amenities, social experience, and market offer. Data comprised an online survey of 318 respondents and 21 structured observations conducted during summer in 2024 and 2025. The preliminary results suggest users perceive the market as a well-maintained, aesthetically pleasing, accessible space, while identifying room for improvement regarding restroom facilities, indoor thermal regulation, noise mitigation, outdoor weather protection and parking arrangements. As for meaningful use and promoting sociability, findings highlight that flexible seating areas that allow high degrees of temporary personalisation and appropriation, alongside tailored programming and diverse activities beyond retail and dining, play an important role in attracting and retaining diverse audiences. While pricing concerns were noted for specific product groups, exclusionary effects appear to be counterbalanced by openness and inclusivity of cultural programmes and free events. The findings contribute to broader urban scholarship discussions calling for new typologies that better capture the changing character of public space use. This research suggests that private-public partnerships involving multiple stakeholders can enhance “publicness” by promoting inclusivity and social life through accessible infrastructure, diverse activities and free events, as well as enabling opportunities for temporary appropriation by users.

Sustainable finance increasingly relies on Environmental, Social, and Governance (ESG) data, yet forecasting ESG-based stock indices remains challenging in an emerging-market context. Using Thailand as a representative case due to limited historical information, this study constructs a realistic simulated SET ESG Index using free-float-adjusted market capitalization and semiannual rebalancing rules that reflect the methodology of the Stock Exchange of Thailand. Using this index as the forecasting target, this study compares traditional statistical time series models (ARIMA, SARIMA, SARIMAX) with seven deep learning architectures (RNN, GRU, LSTM, DF-RNN, DeepAR, DSSM, Deep Renewal) to evaluate performance in multi-step (36-day) prediction. Results reveal that deep learning models significantly outperform statistical approaches, with GRU delivering the highest accuracy and the most consistent robustness across reduced-data scenarios. These findings highlight the ability of advanced AI techniques to capture nonlinear ESG market dynamics better. This study provides a replicable modeling pipeline for ESG index forecasting in data-constrained contexts, with practical implications for sustainable investment decision-making, risk management, and market resilience in emerging economies.

High-quality, interoperable biodiversity information is a prerequisite for effective conservation policy, compliance with European Union (EU) reporting obligations, and efficient environmental decision-making. Greece’s LIFE EL-BIOS (LIFE20 GIE/GR/001317) developed the first National Biodiversity Information System, aiming to aggregate, standardise, and disseminate spatial and non-spatial data for species, habitats, pressures, and trends. This paper provides an economic valuation of this information system as a public, non-market good. We designed a two-stage stated-preference study: (i) a short pre-survey to calibrate initial bids and (ii) the main survey employing double-bounded dichotomous choice (DBDC) contingent valuation with a spike-logit specification. The payment vehicle was a hypothetical monthly subscription in a post-LIFE scenario. The instrument measured time savings (hours), perceived reliability (Likert 1–5), and key demographics/roles. A total of 167 valid responses were collected in September 2025. Participants reported an average of 5.2 h saved per use (median 4; max 14). Among those expressing willingness to pay (WTP), 77% rated EL-BIOS reliability as “High/Very high”. Econometric results indicate time savings as the strongest positive determinant of WTP; perceived reliability is positive and marginally significant; years of experience are negatively associated with acceptance; and cost has a strong negative effect. Mean WTP is estimated at €6.7 per month (median €3.5). Notably, 64% of those unwilling to pay declared protest motives (data should remain public and free). Accordingly, non-payment is decomposed into true zero WTP versus protest-based refusal, i.e., refusal to pay despite acknowledging value. This high protest share reflects principled opposition to paying for public biodiversity data rather than low perceived value of the system. The EL-BIOS database generates measurable productivity gains and social value both through positive WTP and principled protest responses supporting open public data. These findings inform policy on sustainable financing, governance, and long-term operation of national biodiversity information systems. Full article

This study investigates the challenges faced by small- and medium-sized manufacturing enterprises (SMEs) as they attempt to respond to decarbonization demands and expand into renewable-energy markets. Drawing on three waves of free-response surveys conducted between 2021 and 2024, and applying the KJ qualitative synthesis method, the analysis identifies multi-layered constraints across financial, technological, human resource, organizational, and institutional domains. The findings show that the central difficulty for SMEs lies in reconciling exploration—the pursuit of new technologies and business opportunities—with exploitation—the need to maintain and improve existing operations. External stakeholder pressure frequently accelerates this tension, compelling SMEs to initiate environmental actions even when internal capabilities remain insufficient. Based on the emergent patterns, the study develops an “Exploration–Exploitation Support Matrix,” providing a practical framework for policymakers to design coordinated support measures. The study contributes to the integration of eco-innovation, absorptive capacity, and ambidextrous management theories and offers actionable insights for promoting sustainable SME transitions.

Postharvest fungal diseases represent a major constraint to the storage, transport, and marketability of peach (Prunus persica) fruits. Pathogens such as Monilinia spp. (Brown rot), Penicillium expansum (Blue rot), Rhizopus stolonifera (Soft rot), Botrytis cinerea (Gray rot), and Geotrichum candidum (Acid rot) cause significant economic losses globally. Traditional control methods primarily rely on chemical fungicides, which are increasingly challenged by issues of resistance development, consumer health concerns, and regulatory restrictions. This review critically synthesizes the biology, infection mechanisms, and optimal environmental conditions of key fungal pathogens affecting postharvest peaches. It further evaluates the current landscape of chemical, physical, and biological control methods, emphasizing novel approaches including essential oils, microbial antagonists, induced resistance, and eco-friendly sanitizers. Comparative efficacy, sustainability, and practical implementation of these strategies are discussed. Integrated management approaches that combine multiple interventions under low-residue or residue-free systems are highlighted as the most promising direction. This review concludes that the future of peach postharvest protection lies in tailor-made, multi-faceted integrated programs that are both effective and environmentally sound. Full article

Rapeseed (Brassica napus) honey is a popular monofloral honey produced in Poland and is often suspected of pesticide-residue contamination due to the extensive use of pesticides in oilseed rape cultivation. Moreover, because of the presence of fatty acids, it can absorb hydrophobic polycyclic aromatic hydrocarbons (PAHs) that occur as environmental pollutants. Thus, the aim of the study was to assess the safety of rapeseed honey in terms of pesticide residues and PAHs contamination in relation to its functional properties, including antioxidant properties, polyphenol profile, protein content, and enzymatic activity. Local honey samples originating from Lublin (five) and Podkarpackie (five) Voivodeships were compared with five samples purchased from commercial sources. None of 58 pesticides, including carbamates, organophosphorus, organochlorines, pyrethroids, and neonicotinoids, were detected in the tested honey samples. All samples were also completely free of four major harmful PAHs legally limited in food (benzo[a]pyrene, benz[a]anthracene, chrysene, and benzo[b]fluoranthene). Among other PAH compounds, seven were detected accidentally in samples of various origins. The total phenolic content and antioxidant activity determined by DPPH^•, FRAP, and CUPRAC assays were relatively uniform among the groups studied. High-performance thin-layer chromatography (HPTLC) revealed characteristic fingerprints including kaempferol, ferulic acid, and caffeic acid, providing a specific profile that can be considered a marker of rapeseed honey authenticity and used to detect adulteration. Protein content ranged from 18 to 85 mg/100 g, remaining within the range typical for light honeys, while α-glucosidase activity was significantly reduced in commercial products, reflecting the effects of processing and storage. The study confirmed the high functional value and safety of rapeseed honey offered on the South-Eastern Poland market, which confirm the cleanliness of the bees’ habitat in terms of pesticide residues and PAHs pollution. Nevertheless, regular monitoring of pesticide residues and PAHs in honeys from agricultural areas remains advisable. Full article

Background/Objectives: Conventional solidification methods for liquid self-nanoemulsifying drug delivery systems face significant limitations. This includes complex manufacturing processes, high costs, and environmental concerns. This study aimed to develop and optimize a thermoresponsive self-nanoemulsifying drug delivery system (T-SNEDDS) for dapagliflozin as a sustainable alternative solidification technique. Methods: Oil and surfactant were selected based on solubility and emulsification studies. The Box–Behnken approach was used to examine the impacts of three independent variables (pluronic F127, propylene glycol, and dapagliflozin concentrations) on liquefying temperature and time. Optimized T-SNEDDS was characterized in terms of particle size, zeta potential, and dissolution performance. Stability assessment included centrifugation testing and a six-month storage evaluation. The green pharmaceutical performance was comparatively evaluated against five conventional solidification methods using ten adapted parameters. Results: Imwitor 308 and Cremophor EL were selected as optimal excipients for SNEDDS formulation. In addition, Pluronic F127 and propylene glycol were used to induce solidification during storage. The optimized formulation (8.60% w/w Pluronic F127, 10% w/w propylene glycol, and 5% w/w dapagliflozin) exhibited a liquefying temperature of 33.5 °C with a liquefying time of 100.3 s and a particle size of 96.64 nm. T-SNEDDS significantly enhanced dissolution efficiency of dapagliflozin (95.7%) compared to raw drug (42.4%) and marketed formulation (91.3%). Green pharmaceutical evaluation revealed that T-SNEDDS achieved the highest score compared to conventional approaches. Conclusions: T-SNEDDS represents a superior sustainable approach for SNEDDS solidification that offers enhancement in drug dissolution while addressing manufacturing, environmental, and economic challenges through its solvent-free and single-step preparation process with excellent scalability potential.

Wild edible plants contribute significantly to food security, environmental protection, cultural heritage preservation, economic diversification, and the development of communities. In this paper, we present an inaugural ethnobotanical investigation of the traditional knowledge on wild edible plant species from Makkah, Kingdom of Saudi Arabia. Ethnobotanical fieldwork was conducted in Makkah from January to February 2025. Ethnobotanical data pertaining to wild edible plants were collected from 102 informants through free listing, semi-structured interviews, field observations, and a survey of the market. The data were analyzed based on descriptive statistics, the relative frequency of citation, preference ranking, and priority ranking. Forty-one out of one hundred and eighty-four wild plants were gathered and recognized as wild edible plant species belonging to twenty-one families. Poaceae showed the greatest species diversity, comprising five plant species (12%). Phoenix dactylifera L. is the most common wild edible plant. Notably, 11 of the 41 wild edible plants identified in this study had never been reported in the Kingdom of Saudi Arabia before. Wild edible plants are currently threatened by several anthropogenic sources in the research region, including overgrazing, fuel wood collection, and the repeated use of multiple species. Therefore, to ensure sustainable future usage, wild food plants must be used carefully and should be the subject of targeted conservation efforts from all stakeholders. Full article

With the global low-voltage power market expanding rapidly, lead-free dielectric ceramics exhibit excellent stability and environmental friendliness, but their strong field-dependence limits low-field applications. There is an urgent need to develop lead-free ceramic systems with outstanding energy-storage performance under modest electric fields to meet the rapidly expanding global low-voltage power market for bulk ceramics. In this study, high-entropy ceramics (1 − x%)(NaBiBa)_0.205(SrCa)_0.1925TiO₃-x%La(Zr_0.5Mg_0.5)O₃ (x = 0–8) were successfully prepared. The introduced La(Zr_0.5Mg_0.5)O₃ not only dissolves well in the high-entropy elementary lattice but also effectively improves its relaxation characteristics. High-entropy ceramics show optimal energy-storage characteristics, as indicated by an excellent energy-storage density of 4.46 J/cm³ and an energy-storage efficiency of 94.55% at 318 kV/cm. Moreover, its power density is as high as 92.20 MV/cm³, and the discharge time t_0.9 is only 145 ns. Full article

Aroma volatiles constitute the primary molecular basis of fruit flavor quality, governing sensory attributes and marketability. Based on their chemical states, aroma compounds are categorized into bound and free forms. Bound aroma compounds predominantly exist as non-volatile glycosides, which can be hydrolyzed enzymatically or through acid treatment to release volatile free aroma compounds, thereby enhancing fruit fragrance. Although the dynamic interconversion between free and bound aroma compounds is pivotal for fruit flavor development, the governing mechanisms, including the principal controlling factors, regulatory networks, and external influences, are still under investigation. This review primarily synthesizes recent advances regarding the structural diversity, analysis, biosynthesis, and regulation of bound aroma compounds. Additionally, it examines how key regulatory networks and environmental factors modulate the synthesis and transformation of these compounds. The integrated overview provides new insights for future regulation of aroma metabolism in fruits. Full article

Municipal solid waste (MSW) disposal is one of the areas of sustainability development of modern countries including the Republic of Kazakhstan. Annually, more than 4 million tons of MSW are generated, and this amount continues to grow. Additionally, approximately 120 million tons of waste have already accumulated in landfills across the country. It is essential to select an MSW disposal technology that is environmentally friendly, minimizes the generation of more hazardous waste, and maximizes energy efficiency. Ideally, the technology should not only reduce energy consumption but also generate energy and valuable by-products that have market demand. The aim of this study is to conduct experimental research to evaluate the efficiency and environmental impact of incinerating both unsorted and sorted municipal solid waste. As a result of the experiment, the volumes of flue gases and the concentrations of harmful substances produced by the combustion of both unsorted and sorted waste were determined. Additionally, an analysis of the slag and ash generated from the combustion of sorted MSW was conducted. The obtained results enable the development of a waste-free technological scheme for a plant designed for the complete utilization of municipal solid waste. Full article

Tetramethyl bisphenol F (TMBPF) is being increasingly used as a Bisphenol A (BPA) substitute, particularly as a coating material for food and beverage cans. Unlike BPA, TMBPF is considered safe because of the lack of reported estrogenic effects, and it is often marketed under the “BPA-free” label. Initial cell-based assays and rat toxicity studies indicated much lower systemic and sex hormone-related toxicity of TMBPF compared with BPA, which has facilitated its substitution and significant market expansion. Since 2021, however, a growing body of research has reported various adverse effects of TMBPF across multiple biological systems. These include cytotoxicity associated with apoptosis and endocrine-disrupting effects on the thyroid axis, skeletal system, neurodevelopment, and reproductive function. Although the effects on the estrogen and androgen systems, as well as obesogenic potential, show variability across studies, several studies have indicated significant biological impacts. Of particular concern is the potential neurodevelopmental toxicity, which may manifest only after long-term exposure and is often irreversible. Even if current leaching levels from food contact materials are minimal, environmental accumulation and biomagnification over time may pose significant risks. Therefore, comprehensive toxicological profiling of TMBPF is essential. This review summarizes the current toxicological findings on TMBPF and discusses the implications for future research and regulatory considerations, highlighting the importance of early attention to potential public health impacts. Strengthening the toxicological evidence base will help inform regulatory frameworks and support proactive measures to safeguard consumer safety as the use of TMBPF expands. Full article

The utilisation of non-timber forest products (NTFPs) represents a key strategy for coping with food insecurity in rural areas worldwide, often resulting in their gradual depletion and extinction. One of the objectives of landscape restoration programmes is to restore depleted and conserve scarce NTFPs, as well as to preserve their various ecosystem services. However, the impact of these programmes on the well-being of local communities through their access to NTFPs remains understudied. The study focuses on the arid areas of the southern and central parts of the Maradi region in Niger in the Sahel, analysing how the landscape restoration programme contributes to improved access to NTFPs and their subsequent commercialisation to increase household incomes. The probit model with propensity score matching (PSM) reveals, on data from 379 households, that socioeconomic factors such as age, male gender, education level, and number of children, as well as access to NTFPs through donations, increase the chance of being selected as the programme beneficiary. On the other hand, ownership of goats, practising free collection, or purchasing NTFPs were typical for non-beneficiaries. The PSM analysis indicates that beneficiaries sell 11.81% more NTFPs on the market (p < 0.05). Furthermore, beneficiaries earn an average of 7297.40 CFA francs from forest products, compared to 3281.37 CFA francs for non-beneficiaries (p < 0.01). To enhance the impact of the programme, policymakers should prioritise outreach to underrepresented households and incorporate livestock management strategies. Strengthening local markets, storage facilities, and processing infrastructure can boost economic returns. Additionally, combining the conservation of NTFP-producing species with sustainable income activities can support both environmental and community resilience. Full article
