In this case study, we examine how a citrus peel valorising company based in the Netherlands was able to adopt a circular business model while navigating regulatory, managerial, and supply chain-related barriers.

In-depth, semi-structured interviews with key personnel in the company, notes from field observations, photographs of the production process, and documents from a legal judgement served as data for this single, qualitative case study. Data were coded inductively using the in vivo technique and were further developed into four themes and a case description.

Results from our study indicate that the regulatory and political contexts in the Netherlands were critical to the company’s success. Like in the case of most fruitful industrial symbioses, partnerships founded on mutual trust and economically appealing value propositions played a crucial role in ensuring commercial viability. Collaborating with larger corporations and maintaining transparent communication with stakeholders were also significant contributing factors. Lastly, employees’ outlook towards circularity combined with their willingness to learn new skills were important driving factors as well.

In addition to expanding the scholarship on the adoption of circular business models, this research offers novel insights to policymakers and practitioners. It provides empirical evidence regarding the importance of public awareness, adaptable legislation, and harmonised policy goals for supporting sustainable entrepreneurship in the circular economy.

Ensuring high water quality is crucial for safeguarding public health, as contaminated water can pose significant risks to consumers’ well-being. This study aims to evaluate the microbiological and chemical quality of bottled water brands commonly consumed in Dodoma, Tanzania.

A total of 36 samples from 12 brands were collected between January and March 2023 and analyzed for microbiological and general water quality parameters.

Microbial analysis found that 42% of brands tested positive for coliform bacteria, while opportunistic pathogens Aeromonas hydrophila and Pseudomonas aeruginosa were detected in 25% and 17% of samples, respectively. For chemical composition, 42% of brands exceeded the World Health Organization guideline value of 1.5 mg/L for fluoride. However, no other parameters exceeded national drinking water standards. Statistical analysis revealed significantly higher measured fluoride levels compared to values declared on product labels (paired t-test, p = 0.003). A moderate positive correlation between fluoride and conductivity (r = 0.52, p = 0.045) indicated possible geological influences on water chemistry.

To enhance the study’s comprehensiveness, exploring temporal and spatial variations among water brands, including samples from typically clean environments such as supermarkets, could have been beneficial in identifying underlying factors. Additionally, investigating the entire manufacturing process, from production to end-user, could have provided insights into unforeseen deviations in quality. Furthermore, the use of pour plating techniques at 37°C for microbial analysis, while suitable for resource-limited settings, may not have fully captured coliform diversity compared to membrane filtration and differential temperature incubation as per standard methods. This could partly explain the detection of heterotrophs without higher coliform counts in some samples.

This study provides baseline data on the bacteriological and inorganic chemical quality of bottled water in Dodoma. Detectable microbial contaminants and significant exceedances of fluoride guidelines in some products raise public health concerns.

While existing studies focus on bottled water quality at production facilities, this research highlights the overlooked risks at retail points, where consumers are directly affected.

The research aims to assess the relationship between ecological innovation, green productivity, sustainable development and agricultural productivity in Vietnam. The agricultural sector of Vietnam has been observed with new opportunities which have fostered its productivity and growth.

The study uses a range of methods where initially, the researcher used descriptive analysis, cointegration and unit root tests. Secondly, Quantile Autoregressive Distributed Lag (QARDL) is used to assess the short and long run effects. The QARDL methodology is employed to capture the relationship between variables. Through this approach, the researcher is able to examine the scale of the interaction between dependent and independent variables.

The unique findings drawn through statistical techniques are also a great addition to the context of literature related to Vietnam’s agricultural productivity. Practical insights can also not be denied as the study provides beneficial guidelines for Vietnam’s agricultural sector to refine agricultural productivity.

Scholars are advised to use strong literary techniques to overcome these limitations and give a more thorough investigation into the same ideas. The availability and dependability of data was one of the primary challenges in carrying out this study. Vietnam has made significant advances in the collection and documentation of agricultural data, but there might still be gaps in the availability of thorough and current data on ecological innovation, green production and sustainable development.

Vietnam’s unique socioeconomic, cultural and environmental features influence how ecological innovation, green productivity, sustainable development and agricultural production are interconnected. Consequently, consideration should be taken when applying the results to various scenarios.

Organic coatings are widely used for protecting metal equipment and structures from corrosion. Accurate detection and evaluation of the protective performance and service life of coatings are of great importance. This paper aims to review the research progress on performance evaluation and lifetime prediction of organic coatings.

First, the failure forms and aging testing methods of organic coatings are briefly introduced. Then, the technical status and the progress in the detection and evaluation of coating protective performance and the prediction of service life are mainly reviewed.

There are some key challenges and difficulties in this field, which are described in the end.

The progress is summarized from a variety of technical perspectives. Performance evaluation and lifetime prediction include both single-parameter and multi-parameter methods.

This paper gives mining area managers guidance on how to begin this process and which scenario to choose. It aims not only to improve the quality of the environment but also to attend to the well-being of societies previously benefiting from the economic resources of raw materials. However, this task can be difficult to accomplish in countries of the poor South.

Building resilient infrastructure, promoting inclusive and sustainable industrialization and fostering innovation are among WHO’s main goals. Ensuring the possibility of an equitable transition from traditional resource industries to sustainable resource management is a key task for global society.

The transformation of mines into tourist attractions has been studied by several authors. In many countries of the Global North, this transformation has been successful (to a greater or lesser extent). Unfortunately, much remains to be done in many countries of the South. These countries, often at the risk to miners’ lives, engage in mining that is often economically unsustainable. The reason may not only be economic shortcomings but also a lack of conceptual solutions.

The current climate situation presents opportunities to receive funds from Northern countries that can be used for such a transformation.

Regions of the world with a history of transformation from raw material industries to services can provide know-how assistance and knowledge of good practices. Tourism in this aspect can become one of the game changers in the fight for a better future, including tourism itself.

This study explores the direct and indirect effects of two components of food-related consideration of future consequences (CFCs), including CFC-Immediate and CFC-Future, on sustainable food attitudes (SFA) via food-related health and environmental concerns.

Partial least squares structural equation modeling technique was used on a data set of 664 Vietnamese consumers collected in Central Vietnam to evaluate measurement and structural models.

CFC-Immediate and CFC-Future as well as health and environmental concerns have positive effects on SFA. Indirect effects of CFC-Immediate on SFA via health concerns and CFC-Future on SFA via health/environmental concerns are also discovered.

Future studies should examine the impact of environmental values on CFCs, forming a more comprehensive understanding regarding the relationship between the two variables, especially by including a wider range of sustainable food types to gain diverse knowledge about sustainable food consumption.

Communicative messages should focus on both health and environmental concerns while emphasizing both immediate and more distant outcomes of sustainable food (fish) consumption for individuals with different dominant temporal orientations.

This study sheds light on the direct and hierarchical relationships among food-related CFCs, health and environmental concerns and SFA to better understand the intricate psychological process of sustainable food consumption.
