Sustainable Solutions for Modern Economies

This resource brings together world leaders in research on depression, to discuss, for the first time, in an interdisciplinary setting, both classical and innovative ideas to understand this devastating disorder. It presents neurobiological, psychological, genetic and evolutionary models, with a particular emphasis on the mechanisms linking the brain to the endocrine and the immune systems, and therefore linking depression to physical health.

PurposeThe discussion of climate change and energy problems is generally based on the assumption that technical solutions are possible and that the task is essentially to determine the most effective ways. This view relies heavily on the expectation that renewable energy sources can be substituted for fossil fuels. The purpose of this paper is to improve on an earlier attempt to estimate the investment cost that would be involved in deriving total world energy supply from renewable sources.Design/methodology/approachThis discussion improves on an earlier attempt to estimate the investment cost that would be involved in deriving total world energy supply from renewable sources. It takes common assumptions re future energy demand and estimates of future output and capital costs of major renewable energy sources and explores four strategies for supplying global energy demand in 2050.FindingsThis paper finds that the greenhouse and energy problems cannot be solved by action on the supply side, i.e. by technical developments which promise to provide quantities taken for granted in energy‐intensive societies. This general “limits to growth” perspective is that these and the other major global problems can only be solved by action on the demand side, i.e. by moving to ways, values, institutions and systems which greatly reduce the need for materials, energy and ecological resources.Research limitations/implicationsConfidence in the conclusions is limited mainly by the lack of evidence at this point in time on the actual difficulties set by the problem of integrating the intermittent sources, and the resulting need for redundant plant.Practical implicationsEach of the four strategies explored requires large amounts of redundant plant to be able to cope with the intermittency problem. Each leads to total system capital costs which are well beyond affordable levels.Social implicationsThe findings add to the general “limits to growth” case that solutions to the global energy and other sustainability problems cannot be achieved within consumer‐capitalist society but must be sought via dramatic reductions in production, consumption and GDP. This would require radical system change from the commitment to growth, market systems and affluent lifestyles, to what is described as The Simpler Way.Originality/valueIt does not seem that this approach has previously been taken to the specific issue of the potential and limits of renewable energy. Little or no attention has been given to the thesis that global sustainability and justice require transition to some kind of Simpler Way.

In the modern socio-economic context of the development of educational systems, the processes of globalization and internationalization play an important role, which determine the reformation of higher education. Competition and cooperation between educational and scientific organizations are intensifying all over the world, the exchange of students, teachers, graduate students and researchers is intensifying, distance education is becoming widespread, and the role of continuing education is growing. The purpose of the research is to identify and justify system-wide trends in the renewal of European education. The main task of this research is to determine the mechanisms and characterize the orientation of the renewal of the European education system under the conditions of internationalization and globalization. The methodological basis of the research consists of: the general scientific principle of objectivity; the principle of historical and logical unity; systemic and contextual approach, principle of interconnection; sociological, cultural and pedagogical concepts. It is determined that today the European Union is one of the world leaders in research and innovation. It is scientific knowledge, experience, high standards of the research, developed research infrastructure that guarantee many years of successful cooperation between the EU and other countries. At the present stage, investments in higher education and vocational training are considered as the most important factor in enhancing the EU’s competitiveness and ensuring the constant growth of its economy. The development of higher education is perceived as the most important prerequisite for achieving the economic, social and environmental goals set in 2000 in Lisbon. Higher education is the core of the new European society, based on the knowledge. The article considers the direction of transformations carried out in the higher education systems of the European Union countries in the context of the internationalization of education. The strategic goal of reforming the European education system is to increase its competitiveness in the international space and modernize economies. In the political and public circles of the European Union, the opinion has been established that since human resources are the most important wealth of the EU, education policy should be the main factor in the processes of knowledge creation and transfer, which, in turn, crucially determine the innovative potential of the society. In this regard, the main goal is to provide equal and open opportunities for people of all ages to receive high-quality education and to gain diverse educational experiences throughout Europe. Education systems are a key link in the implementation of this concept. This paper traces the dynamics of the external dimension in the political and socioeconomic contexts. The Maastricht Treaty of 1992 established the basis for the EU cooperation within higher education. It stipulated the commitment of the member countries to develop education cooperation with third countries and international organizations. The European Commission has called on EU member states to take the necessary measures to reform their education and training systems so that barriers between formal and non-formal learning disappear. To implement this concept, it is necessary to achieve a higher level of interaction between the main participants in this relatively new area: business, social partners and educational institutions.

New perspectives for sustainable resource and energy use, management and transformation: approaches from green and sustainable chemistry and engineering

Green and sustainable chemistry is a rapidly developing field dedicated to creating chemical processes and products that minimize environmental harm, minimize waste, and optimize resource use. There has never been more demand for sustainable solutions because of rising concerns about pollution, climate change, and resource scarcity. This field incorporates fundamental principles such as utilizing renewable resources, minimizing hazardous chemicals, enhancing energy efficiency, and designing biodegradable, non-toxic materials. Green chemistry (GC) is essential across diverse sectors, that includes agriculture, pharmaceuticals, materials science, along with energy production. Its implementation seeks to not only lessen the negative impacts of conventional chemical processes but also drive advancements in cleaner production techniques. These include the adoption of green solvents, biocatalysts, and renewable raw materials. By integrating such sustainable approaches, industries can achieve both economic success and environmental protection. GC is essential to addressing global concerns that include pollution control, resource conservation, and transition to a circular economy. This paper underscores significance of GC in key areas such as healthcare, agriculture, industry, and energy. Embracing GC principles supports economic progress, environmental stewardship, and public health improvements. Embedding sustainability into chemical research and industrial operations contributes to long-term ecological balance and resource efficiency. Additionally, this paper explores the obstacles to the widespread adoption of green chemistry and proposes strategies to overcome these challenges, ensuring broader implementation for a more sustainable world.

Production of high grade fuels and chemicals from catalytic pyrolysis of biomass

The rising influence of greenhouse gas (GHG) emissions from burning fossil fuels on climate change has led to a demand for clean energy. The only consequence of H2's combustion is water vapor, making it a clean energy source. As a clean energy source, hydrogen contributes significantly to energy and environmental sustainability and helps mitigate the world's energy problem and climate change. Microalgae have recently been found to hold tremendous promise for producing biodiesel and biohydrogen. Under certain conditions, sunlight is used by green microalgae to split water particles, resulting in the production of molecular hydrogen and oxygenation. With an emphasis on green microalgae, this review outlined possible algal strains for hydrogen production. In addition, a comprehensive review procedure aimed at presenting the importance of using microalgae to produce green hydrogen. More significantly, this review included an overview of present constraints and potential future directions for the sustainable synthesis of biohydrogen from microalgae.

An embargo on the export of Australia's vast uranium mineral resources has been in force for several years. Pressures to lift the embargo are mounting. A Royal Commission has enquired into all aspects of uranium mining and exports. This paper, modified to some extent, forms part of a submission to this enquiry. It is suggested that nuclear power be accepted as an interim solution to the world's energy problems. the plutonium fuelled breeder technology as the ultimate solution is rejected. Meanwhile the striking of a $750 (Australian) export levy per tonne of U3O8 will provide the funds for research and development in the use of renewable energy sources. Restrictive conditions imposed on the sale of uranium minerals and their beneficiated derivatives include guarantees against the separation of plutonium and the development and use of a plutonium technology.

The conversion of solar energy to sustainable energy sources is a significant field of study for the relief of the world's energy problems, and among the various strategies developed, semiconductor photocatalysts have received significant attention as a promising candidate due to their attractive efficiency, mild reaction conditions, and low cost. The enhancement of such photocatalysts with plasmonic materials, by virtue of the Schottky junction and localized surface plasma resonance phenomenon, could facilitate the rapid progress in enhancement of photocatalytic efficiency under visible light irradiation. To further improve photocatalytic efficiency, scientists look to nature for inspiration, culminating in the evolution of complex hierarchical structures in order to fully utilize the potential of solar energy. In the past decade, there has been significant progress in the development of bio‐inspired plasmonic photocatalysts, such as antireflective surfaces, 3D photonic structures, and branched structures. This review describes the state‐of‐the‐art bio‐inspired light manipulation approaches, as well as future challenges in solar energy harvesting by plasmonic photocatalysts.

In the context of global climate change and the imperative to reduce greenhouse gas emissions, the Republic of Moldova, like many other nations, faces the challenge of transition to cleaner and more sustainable energy sources. Renewable energy sources are promising alternative to traditional fossil fuels, with the potential to enhance energy security, reduce import dependence, and foster sustainable economic development. As an agrarian economy, the Republic of Moldova has significant potential for energy production from renewable sources, including biomass. Integrating biomass-based energy generation technologies into the district heating system could effectively diversify the energy mix and improve the sustainability of the national energy system. This paper assesses the feasibility of integrating direct biomass combustion technologies into the district heating system from municipium Balti (DHS-Balti), one of the largest producers, distributors, and suppliers of thermal energy. The analysis showed that biomass-based district heating systems are economically viable and contribute to the decarbonizing the DHS-Balti system. The biomass potential in the region allows the integral coverage of the existing district heating demand. The levelized cost of thermal energy produced by biomass heating systems is 12-15% lower than that of natural gas systems. Greenhouse gas emissions could be reduced by 63–76 thousand tons of CO2 per year.
