Objective – The circular economy aims to preserve the value of products and materials within a closed supply chain. The existing models and decision-making methods for managing the end of the product life cycle are mostly focused on the economic aspects. While the circular economy is aimed at combining environmental, economic and social goals. This article aims to develop a model for enterprise decision-making on the disposal of used products, taking into account socio-environmental and economic factors. Methodology/Technique – The article analyzes the impact of digital technologies on the formation of closed supply chains and the development of a circular economy. At the same time, special attention is focused on the model of a closed product life cycle, as a fundamental element in the formation of a circular economy at the micro and nano levels, as well as the importance of using digital technologies at all stages of the product life cycle. Findings –The methods of product management at the end of the life cycle studied in the article have made it possible to form a simulation decision support model regarding the method of product disposal, taking into account environmental and economic feasibility. Novelty – This study identified the main trends in the development of closed supply chains under the influence of digital technologies in the context of a circular economy. Type of Paper: Review JEL Classification: F42, F43 Keywords: Circular Economy; Digital Technology; Decision-making Model; Closed-loop Supply Chains Reference to this paper should be made as follows: Vetrova, M; Ivanova, D.

Promoting the concept and principles of sustainable development at the micro level requires that industrial companies understand and improve approaches to managing corporate sustainability. Currently, economics does not provide a universal definition of what corporate sustainability is. With regard to the mining sector, corporate sustainability issues reflecting the viability, value, and sustainable development potential of companies have not yet been studied extensively. The article discusses the conceptual foundations of corporate sustainability; the characteristics and a classification of approaches to defining corporate sustainability; and the relationship between corporate sustainability, sustainable development at the micro level, and circular economy. By analyzing the example of Russia, the influence of the mining industry on the environmental, economic, and social development of both a country with a resource-based economy and individual mining regions is shown from the viewpoint of sustainability. The distinguishing features of mining companies, which include natural capital and mineral assets, are studied in the context of promoting corporate sustainability. It is proven that the effective corporate management of ESG factors results in environmental and social influence that goes in line with sustainable development requirements and serves as a foundation for corporate sustainability. A refined definition of corporate sustainability has been formulated, the specific features of corporate sustainability management in mining companies have been determined, and the specific features of corporate social responsibility have been studied. The issue of integrating circular economy elements into the corporate sustainability concept is discussed, and it is claimed that the inclusion of circular business models in the corporate strategies of mining companies will contribute to their corporate sustainable development and boost their contribution to the achievement of sustainable development goals.

Summary The following paper explores circular economy as a model of management within the framework of sustainable development. Its structure comprises 4 parts. The first part illustrates the role of sustainable development as an emerging paradigm in the theory of modern economics and in the recent policy of the European Union. In the second part, the authors demonstrate the applicability of sustainable development based on the relevant management models on the micro, meso and macro levels of economy. The third part discusses the concept of circular economy, in particular the various definitions of the phenomenon, its advantages over the linear economy, the role of innovations in its development and how to overcome barriers to its application. The fourth part outlines the current state of implementation of the circular economy in the EU in regard to its normative implications for the member countries. The conclusions close the exploration. The paper is theoretical, based on the review of the international literature on the subject. The unique contribution of the authors consists of the systematic analysis of the term circular economy as a holistic model of sustainable development and of illustrating the benefits of its promotion in the management practice.

Purpose As a prominent actor in terms of achieving sustainable socioeconomic development, especially in rural areas, Islamic banks are urged to pursue their main objective. It is required to set the objective accordingly from time-to-time to continuously make a positive contribution to the sustainable socioeconomic development. Hence, the integration of the external factors such as government’s economic target (macro) into Islamic banking’s objectives (micro) is needed. Design/methodology/approach This research attempts to identify factors that might prevent the sustainable economic development activities within the micro–macro circular causal model established by Tawhidi String Relation (TSR) methodology. Findings The research clearly found that the existing Islamic banking’s business and directions had an uncorrelated connection with Indonesia’s economic objective. Nevertheless, the Islamic banking’s Musharakah and Mudharabah contract for Usaha Mikro Kecil Menengah [(UMKM) (Micro, Small Medium Enterprises)] was showing the positive correlation to their financial performance indicator. Hence, Islamic banking is strongly suggested to be more focused on these two types of partnership financing contract to UMKM. Furthermore, its value and volume is needed to be expanded to build Indonesia’s sustainable socioeconomic foundation. Then the positive gross domestic product (GDP) growth will be achieved. Originality/value The existing research covering the sustainability index is mainly only based on the macro perspective, while in this research, the integration between the micro and macro perspectives between government objectives and Islamic banking objectives is needed. This interaction and integration between the two are in line with the concept of the TSR methodology.

Purpose The purpose of this paper is to explain the structure of Islamic monetary transformation into 100 percent reserve requirement monetary system in terms of the foundational epistemology of the unity of divine knowledge (tawhid). This approach is a scholarly originality in the field of epistemological formalism concerning Islamic theory and perspectives in economic reasoning in comparative perspectives. Design/methodology/approach The role of micro-money pursuing projects and real economic exchange relations is shown to arise by a natural causality in the ethical social economy (SE). This results in a microeconomic perspective of the quantity theory of money with ethical and social implications. A comparative study of endogenous money in the quantity theory of money points out significant differences between the theory of endogenous money in Islam and mainstream methodologies. A formal model of micro-money and its organismic endogenous relationship with the real economy is formulated with the goal of realizing social well-being, economic stabilization, and sustainability of development regimes. Findings This is a conceptual paper, though with the potential for continued work in applying the theory of micro-money in the Islamic methodological perspective of unity of knowledge. This is an original contribution of this paper. Islamic economists have not been able to produce a rigorous theory of micro-money. They have also not been able to situate the study of Islamic economics with its specific contribution to the field of the nature of money in project-specific financing of Islamic projects by the money-finance-real economy inter-causal relations. Thus, the findings of this paper, though of the conceptual nature, open doors to a vast field of methodological development and its application to the problem of micro-money modeling. Such a conceptual finding arising from the methodological theory of unity of knowledge and applied to the topic of micro-money along with some examples of potentiality of these approaches constitutes a vastly original field of findings as contribution. Thereby, an analytical model is established in the Islamic social economy (ISE) perspective. The model is used to explain monetary transmission and functioning of monetary policy with instruments that avoid interest rate and comply with Islamic financing requirements. The resulting model of money, finance, and real economy (MFE) systemic interrelationship in reference to the epistemology of unity of knowledge leads into the construction of a 100 percent reserve requirement monetary system with the gold-backed micro-money as currency complementing real economic transactions. Research limitations/implications The present paper is of a conceptual type based on the essential ontological and epistemological foundation of Islamic social and economic thought and bearing a deeply scientific implication. The conceptual part of this paper becomes a study in the foundations. The second part follows into the study of application in the real world of micro-money in terms of financing projects. Micro-money pursues projects in the Islamic economy due to its very nature of ethical and social choices. The paper shows that such a micro-money transmission is realized by the money-finance-real economy integrated model. Thereby, some real-world examples of such transformations are given. All these together substantiate the conceptual-analytical-empirical nature of the study conducted. Practical implications The development of the micro-money transmission system of generalized circular causation interrelations between MFE activities as a return to 100 percent reserve requirement monetary system with the gold standard is the profound theory that has been propounded. Its applied perspectives are implied through the MFE-model wherein micro-money pursues social projects. Furthermore, the possibility and practicality of such a conceptual model of micro-money and its transmission mechanism in the real economy are established by real-world examples of kinds of micro-money that are found to circulate or are recommended by some studies in the literature. Social implications The conceptual part of the paper presents a model of generalized epistemological model of unity of knowledge characterizing the MFE circular causal interrelations as the organismic meaning of social ethics and evolutionary learning. The social implications are the epistemic foundations of the derived model in the midst of choices of life-fulfillment projects that micro-money finances and the economy sustain. Originality/value This is an original paper premised on the general and the specific Islamic epistemological criterion of unity of knowledge as a generalized system theory. It is now particularized to the case of money and real economy by using the Islamic perspective of creating conditions to regenerate resources continuously in SE with ethical implications. The paper is equally informative to all who like to understand the social and ethical nature of endogenous relations between money and the real economy as two great institutions of the national economy. These together bestow well-being to the society at large in the construction of SE. Specific attention in this regard is given to ISE.

The ability of Industry 4.0 to help solve complex economic and social problems and implement complex concepts is assessed. Currently, one of the greatest challenges is the integration of the circular economy (CE) into real business practices. However, the link between these two ideas is not fully recognised, causing an interpretative dilemma. Therefore, the aim of this paper is to identify the relationships between the CE and Industry 4.0. For this purpose, we performed a systematic literature review and content analysis of selected articles indexed in Scopus, Web of Science, ScienceDirect, and EBSCO. In total, 32 papers published during the period 2017-2020 were analysed. The findings show a one-way relationship, i.e., Industry 4.0 leads to a CE, and a two-way relationship, indicating synergy between these concepts. The key spheres of the CE in terms of Industry 4.0 are the recycle and reuse strategy applied in smart production and a sustainable supply chain. This study demonstrates the importance of company (micro) and industry (meso) levels as application areas. The most promising digitalisation tools of Industry 4.0 are the Internet of Things (IoT) and Big Data Analytics. The article concludes with the limitations of the study and a formulation of directions for future research.

Background: Global environmental and social research strengthens the protection of people and the environment, develops national capacity for social and environmental management and enables significant progress in terms of transparency, accountability, nondiscrimination and public participation. The support of the general public plays a key role, as it contributes to making public institutions more transparent, accountable and efficient and promotes ground-breaking solutions to complex development challenges. Citizen engagement seems particularly vital throughout the crises such as the COVID-19 pandemic, as the efficiency of response efforts may frequently depend upon micro-level behavioral changes. The objective of this paper is to provide a complex evaluation and rating of countries based on the social component of the global inclusive circular economy, taking into account the shocks and reverberations experienced by the economy as a whole caused by the COVID-19 and war in Ukraine. The results are presented as a global ranking of countries based on the social component of the global inclusive circular economy. They confirm the high value of this component in the integrated indicator, which validates the hypothesis that inclusiveness is a necessary aspect of the global circular economy. The research results identify the countries capable of offering the best management solutions to social disbalances and other weaknesses, as well as the countries in need of model examples to tackle these issues.

This work describes the design and analysis of a 22 circular micro-strip patch antenna array on a FR-4 epoxy substrate. The thickness of the substrate is 1.6 mm, and it is used in a variety of applications, including RADAR and radio frequency identification. The task involves creating a 22 circular microstrip patch antenna array that resonates at 2.4GHz and simulating it for use in Wireless Sensor Network (WSN) applications. An FR-4 Epoxy substrate is used to create a circular patch antenna array, which is then supplied using microstrip feed lines. A manufactured antenna has a 1.187GHz resonance. The analysis of antenna parameters includes gain, return loss, VSWR, directivity, reflection coefficient, and radiation pattern. In comparison to a 2x2 rectangular microstrip patch antenna, a 2x2 circular microstrip patch antenna generates better gain and less return loss. It is more helpful for WSN applications than a rectangular array due to its small size and improved directivity.

Case overview Odds & Edge, a micro venture based in Ahmedabad, India, has created a niche for itself in the affordable designer wear segment. Covid-19 induced lockdown pushed Odds & Edge to the brink of collapse. And because of the severe cash crunch partners need to take a call regarding the continuation or closure of the venture. The case is intended to be discussed in an entrepreneurship class for post-graduate level participants. The case setting is inside Odds & Edge and it was May 01, 2020, when Ms Jheel Jain - a partner & the protagonist, needed to decide the future of the venture. Participants will have a brief understanding of entrepreneurial traits and will also learn about the Ansoff Model of expansion in case of continuation and the different exit choices for an entrepreneur. As Odds & Edge operates in the fashion industry, students will be able to understand the concepts such as Ecopreneurship, Circular Economy, and Trashion. The case follows through the background of Ms Jain, the ideation stage, and the players in the Trashion Industry. It then moves on to the operation of Odds & Edge narrating the process, products, and partners of the venture. The case ends with the decision dilemma for Ms Jain i.e. should she continue? If yes then how could Odds and Edge expand & grow? Or Should Jheel surrender and exit? If yes then what are the probable exit choices for her? Learning objectives 1. to understand the concept of Ecopreneurship, Circular Economy and Trashion; 2. to identify and discuss common entrepreneurial traits; 3. to analyze the Ansoff Matrix for exploration of various expansion/growth strategies; and 4. to understand different exit strategies available to an entrepreneur.

For each region of France, there is currently a program to implement a plan for regional prevention and management of construction and demolition waste (CDW) used in the buildings and public works (e.g., roads) sector, also called the BTP (from the French Bâtiment et Travaux Publics) sector. To implement such a plan, its complexity must be considered; i.e., account (a) for how different scales are endogenously connected and (b) for decision-making rules at each scale being introduced. However, this complexity has rarely been taken into account in the literature. Using the PACA region as a case-study, this paper presents the first results of modelling that determines a hypotheses for the geographic distribution of the road renovation rate in each municipality (microscale) and Department (mesoscale) in a region of France. Such a renovation requires recycled aggregates (gravel) and asphalt supplies simultaneously. To consider this endogenous connection between scales, the model at the micro-scale must also be calibrated so the simulated values emerging at a higher-scale approach a supply–demand balance. We also discuss the transposition of the model to another French region (Ile-de-France). The method we used is the Agent-based Computational Economics (ACE) modelling approach. In addition, the coherent interplay between scales is determined by an approach called pattern-oriented modelling (POM). Our research revealed, at a thematic level, that for a circular economy to develop, the network of facilities in the territory is very important, and effective commercialization of secondary resources is major in the areas that group together recycling platforms and nearby asphalt plants. At a methodological level, our research revealed that in any multi-level modelling exercise, POM can be seen as an essential approach to accompany the ACE approach, particularly for a macroeconomic (here macro = regional) looping of a model designed at a microscale. However, convincing the BTP sector to integrate ACE/POM as a full part of a methodological support for regional prevention and management of CDW remains a challenge

Zheng, Meris. "A critical analysis of current practices in the treatment of household food waste in Australia: strategic and technical improvements within a Micro Circular Economics (MCE) context." Thesis, 2020. https://vuir.vu.edu.au/42169/.
Повний текст джерелаАнотація:
Food waste (FW), generated from the point of production to the dinner table, represents approximately one third of all the food produced worldwide. It is estimated that more than 95% of household food waste (HFW) goes to landfill and is the major contributor to greenhouse gas (GHG) emissions from such sites, with other environmental impacts such as pollution of groundwater. There are also significant costs involved with the management of FW worldwide. These issues are compounded by increasing urban populations and there is an urgent need to better address the management and disposal/treatment of FW generally - and HFW in particular. In order to achieve this, more research is urgently needed to obtain specific information on the details of HFW management and on the development of appropriate technologies that are consistent with a micro circular economic (MCE) approach. To this end, an extensive review of HFW management and technology worldwide has been conducted.
Together with the above information, in collaboration with three local Councils, research has been undertaken with respect to the Melbourne metropolitan area specifically that involves the design and implementation of a strategy to survey residents across three different well-defined dwelling types, in order to obtain detailed information on their household management and disposal of domestic food waste. Thus, an extensive survey has been designed and conducted that separately targets residents of detached houses, semi-detached/low-rise and high-rise dwellings. This survey has revealed differences in HFW management, attitudes and practices, that that depend on dwelling type - and that also provide important general information and data that has informed the subsequent design, construction and testing of a miniaturized anaerobic-digestion (AD) pilot-plant. This information is of both a qualitative and quantitative nature. For example, it is important to know both the nature and the quantity of the food waste generated as well as residents’ attitudes towards disposal and treatment. The designed and constructed pilot plant is meant to serve as a prototype for the on-site treatment of HFW that will produce biogas for domestic consumption. An ultimate goal here is to utilize HFW to supplement a household’s gas supply and at the same time remove the necessity of sending HFW to landfill.
Thus the pilot-plant experimental program has collected and analysed replicate temporal data on the effect on biogas (CH4) production of parameters such as household food waste composition and quantity (as informed by the survey) and texture, the nature of the inoculate, operating conditions such as pH and temperature, oxygen infiltration and fatty acid production - as well as design aspects such as the footprint, the number of tanks and the required control equipment. In terms of biogas yield, a multiple tank set-up has been found to be superior to a single tank set-up and an important aspect has been found to be an appropriate mixing of food waste substrate between AD tanks that results in an increased biogas yield.
In summary, the combination of an extensive targeted survey of HFW management in the Melbourne metropolitan area, coupled with the design and trialling of a potential household pilot plant for the on-site generation of biogas, has yielded valuable information that will eventually result in a commercially viable product.

The aim of this book is to present the most important issues related to sustainable development (SD) and corporate social responsibility (CSR). They are discussed from a macro and micro perspective, both in the form of theoretical foundations of these concepts and practical examples of companies operating in Central and Eastern European countries that have implemented these ideas in their daily operations and translated them into corporate and functional strategies. The book consists of four parts. The first one is theoretical in its assumptions and is devoted to explaining the key concepts of sustainable development (SD) and corporate social responsibility (CSR). The authors describe the determinants of sustainable development in the contemporary world, including the most important ones, such as globalization, climate change, poverty, unlimited consumption, as well as limited access to natural resources - all in relation to the goals of sustainable development. The chapter also discusses the concept of corporate social responsibility (CSR), which is now recognized as the process by which business contributes to the implementation of sustainable development. How sustainable development (SD) and corporate social responsibility (CSR) are incorporated into the organization's strategies and influence the corporate strategy on the corporate and functional areas of the organization is presented in the last chapter of the first part of the e-book. The next part of the e-book helps readers understand the concepts of SD and CSR in the field of organizational strategy - in strategic management, and at the level of functional strategies—marketing, human resources, marketing research, accounting and operational management. The authors explain the reasons why companies need to consider the local and global perspective when setting SDGs, and the existence of potential conflicts within them. Taking into account the area of marketing, the authors point to the increase in environmental and social awareness of all stakeholders, which translates into changes in the criteria for decision-making by managers and risk assessment. The issue of sustainability is also the subject of market research. Companies producing products and services, institutions dealing with environmental or consumer protection, scientists and students conduct many research projects related to, inter alia, much more. How to use secondary data for analysis and how to prepare, conduct, analyze and interpret the results of primary research in that area are discussed in detail in the next chapter of this section. The concept of SD also refers to the basic functions of human resource management (HRM)—recruitment, motivation, evaluation and control. They should take into account SD not only for the efficiency of the organization and long-term economic benefits, but also for ethical reasons. Thanks to the SHRM, the awareness and behavior of the entire organization can strongly express sustainable goals in the planning and implementation of the overall corporate strategy. The growing importance of the idea of SD and the concept of CSR also resulted in the need for accounting and finance to develop solutions enabling the provision of information on the methods and results of implementing these concepts in entities operating on the market. This part of the book also examines manufacturing activities in the context of sustainability. As a result, many problems arise: waste of resources, mismanagement, excessive energy consumption, environmental pollution, use of human potential, etc. The chapter presents such concepts as: zero-waste, lean-manufacturing, six-sigma, circular production, design and recycling products in the life cycle as well as ecological and environmentally friendly production. The next two parts of the e-book contain examples of companies from Central and Eastern Europe that used SD goals in their strategies, questions and tasks for readers.

AbstractUrban Metabolism (UM) is a scientific phenomenon that comprises individual processes taking place in all cities at different spatial and temporal scales and that is based on the principle of conserving mass and energy. Analysing the metabolism of a city allows one to evaluate the impacts of urban functioning, taking into account the flows of energy, water, nutrients and waste and the materials in general that circulate within a city, and contributing to a multidimensional assessment of sustainability. Many authors have explored the phenomenon of UM and experimented with indices and evaluation methods, but there is still no consensus on the best assessment methods to use.The present paper presents an overview of UM assessment methods, particularly Life Cycle Assessment (LCA) and its possible uses for supporting territorial regeneration. A literature analysis is conducted of the evolution of this method in relation to scales that are different from the single product scale. LCA aims to assess the environmental impacts of the life cycles of single industrial products and services, but over the years it has gained increased attention in the urban planning field. Life cycle, in general, refers to all the phases that characterise the life of elements, comprising not only a single product, but extending this concept also to the wider territorial system. The concept of the life cycle of territorial systems is related to the evolution of the territory as a heritage and as a system of environmental, social and economic resources and services, whose transformation is linked to the different forms of governance. The territorial life cycle is formed by interconnected phases, referred to as the sub-systems of the resources and performance of a territory, that follow a predefined plan scenario. Consequently, the life cycle concept can be compared to that of change and it is closely linked to the analogy of ecosystems and the urban environment, which views the city as an entity in constant transformation.In the last few years, there has been an increase in activity in the LCA application field, with the introduction of scale variations and of the distinction between applications at the level of the single product and applications at the meso and macro levels. In other words, this approach is evolving and applications and hypotheses involving scales different from the micro scale are becoming popular.In this regard, extending the LCA tool to a meso perspective on a municipal scale or an individual urban district scale could prove to be a valid tool for assessing the sustainability of a territory with regard to the metabolic flows and the evolution of its life cycle.

It is crucial for business organizations to maintain sustainability within the globalized market environment. However, the organizational ability of micro, small, and medium enterprises (MSMEs) is inadequate to generate sustainable competitive advantage. Moreover, strategic management theories are developed based on large business organizations which cannot be fully applied in MSMEs. From this knowledge gap, this research study addressed the core question of “Does strategic human resource management (SHRM) and organizational learning impact the sustainability of service-based MSMEs in Brunei Darussalam, with competitive strategy as mediator?” From a questionnaire survey of 275 service-based MSMEs, this research study confirmed SHRM and organizational learning to yield significant impact on organizational performance of service-based MSMEs. These results are partial significantly mediated by competitive strategy. From these findings, this research study extended the knowledge on resource-based view, contingency theory, and organizational alignment theory within the MSME context.

This research studies the case of KT to see how a mobile operator expanded beyond its existing offerings to new smart energy business based on digital technology. Details were analysed specifically on how the business was developed, why the smart energy service was started, and what the success factors were. KT's smart energy business (KT-MEG: KT Micro Energy Grid) utilizes ICT to resolve energy issues such as global climate change and energy consumption growth. It also provides growth opportunities for KT with its KT-MEG platform. The authors analyze that KT was able to leverage sustainability as a new growth engine by developing new businesses to differentiate customer experience, create effective organization structure, and generate business impact in addition to application of latest ICT technologies such as artificial intelligence, IoT (internet of things), and big data. The results provide a good guideline for business transformation of ICT firms in the era of Industry 4.0.

Green products and services have become an important part of consumption, as consumers' knowledge and concern towards environmental sustainability has increased and they have started to concentrate on their environmental impact. Nonetheless, green marketing still constitutes a small portion of the overall consumer spending. This chapter aims to highlight the importance of marketing activities in the adoption and social normalization of green consumption by the consumers generating public support and economic benefits for the companies as well as environmental and social gains for the society in return. Combining both micro and macro-level determinants and consequences, a conceptual framework is suggested which aims to contribute to literature both theoretically and practically.

Tofu factories are spread across Indonesia as tofu is a cheap source of protein and favorite food for almost all population groups. Most tofu producers are micro/small business owners. In addition to soybeans, clean water is the most important input to produce tofu curd. It will generate a large amount of wastewater and solid waste, which still contains significant amounts of easily biodegradable organic matter. There are often complaints and protests from the public about the pollution in air and water in the area from the discharged waste. Tofu producers know about this, but their limited income and capital force them to ignore the environmental issues. The potential of tofu waste treatment technologies to produce new products or clean materials that can be fed back into the production process is discussed and reviewed to ensure all input materials in the tofu process can be used optimally and efficiently in a closed-loop production process. And it could be implemented easily and economically by the factories.

Recently, micro/nanofabrication technology has been used to develop a number of microfluidic systems. With its integration to microfluidic devices, microchannels and micro scale pin fin heat sinks find applications in many areas such as drug delivery and propulsion in biochemical reaction chambers and micro mixing. Many research efforts have been performed to reveal thermal and hydrodynamic performances of microchannel based micro fluidic devices. In the current study, it is aimed to extend the knowledge on this field by investigating heat and fluid flow in micro heat sinks at high flow rates. Moreover, thermodynamic and thermo-economic aspects were also considered. De-ionized water was used as the coolant in the system. Flow rates were measured over pressures of 20–80 psi. A serpentine heater was deposited at the back of the micro pin fin devices to enable the delivery of heat to these devices. Two micro-pin fin devices each having different geometrical properties (Circular based and Hydrofoil based) were used in this study. In addition, the performances (thermal-hydraulic, exergy, exergo-economic) were also experimentally obtained for a plain microchannel device. Thermal resistances, exergy efficiencies and thermo-economic parameters were obtained from the devices and their performances were assessed.

Micro electric discharge milling (μ-ED milling) is an effective and economic process for the fabrication of micro channels. In the present work, the bulk approach of μ-ED milling is being attempted to make complex shaped micro channels. For a straight channel the bulk approach of μ-ED milling was found to be a successful approach. A tungsten tool of diameter 500 μm was used to fabricate semi-circular micro channels on EN-24 steel. Important machining parameters had earlier been optimized to make straight channels on EN-24 steel by the same method. The effect of geometrical parameters such as radius of curved channel and aspect ratio on MRR and TWR were studied by full factorial experimental design for single pass at optimized machining parameters. Finally complex shapes like T-type and serpentine channels were made by using optimized conditions of straight and curved channels by bulk approach with multiple passes of μ-ED milling.

The authors have studied for the effect of supplying oxygen into water with micro bubbles produced by the shearing method, and found that the micro bubbles are very effective for the oxygen supplying compared with general size bubbles. We also generate micro bubbles which make water cloudy through the pressurizing dissolution method. The average diameter of micro bubbles generated with this method is about 40 micro meters in our laboratory. They are much smaller than those produced by the shearing method, and are the similar size to the tracer or the reflector used to measure the flow field by the PIV or the UVP (Ultrasonic Velocity Profile monitor). Moreover, they are very economical and ecological compared with solid tracer particles. Therefore, we examine to apply micro bubbles generated with the pressurizing dissolution method to the measurement of liquid flow field using the PIV or the UVP. A flow in a square cavity at Re = 1000 was measured using the PIV and the UVP. We could recognize a clear vortex. A flow around a circular cylinder was also measured using the PIV. We can recognize the possibility of micro bubbles for these applications.

Abstract The urgent need to decrease greenhouse gases (GHG) has prompted countries such as the UK and Norway to commit to net zero emissions by 2050 and 2030, respectively. One of the sectors contributing to GHG emissions is agriculture, by approximately 10% in the EU in 2017. GHG reductions in the production side should involve avoidance at source, reduction of emissions and/or removal of those emissions, with the potential for negative emissions by carbon capture. This paper focuses on the utilisation of agricultural waste that can be converted into biogas, such as livestock and crops residues which represent around 37% of GHG emissions by agriculture in the EU. The biogas can be used to produce electricity and heat in a micro gas turbine (MGT). Then, the exhaust gases can be sent to a carbon capture plant. This offers the potential for integration of waste into energy for in-house use in farms and fosters a circular-bioeconomy, where the captured CO2 could be used in greenhouses to grow vegetables. This could even allow the integration of other renewable technologies, since the MGT offers flexible operation for rapid start-up and shut down or intermittency of other technologies such as solar or wind. Current carbon capture processes are very costly at the smaller scales typical of remote communities. The alternative A3C (advanced cryogenic carbon capture) process is much more economical at smaller scales. The A3C separates CO2 from process gas that flows counter-currently with a cold moving bed, where the CO2 desublimes on the surface of bed material as a thin layer of frost. This allows enhanced heat transfer and avoids heavy build-up of frost that reduces severely the heat transfer. The phase change separation process employed by A3C and the large thermal inertia of the separation medium gives good flexibility of capture for load changes and on-off despatch. This study integrates a combined heat and power MGT, Turbec T100, of 100 kWe output. This include developed models for the MGT using characteristics maps for the compressor and turbine and for the cryogenic carbon capture plant, using two software tools, IPSEpro and Aspen Plus, respectively.
