This paper is concerned with electrolysis processes aimed for production and refining of metals. This engineering field is named electrometallurgy. The main aspects of electrometallurgy such as electrochemical, energetic/economic and environmental ones are given. The peculiarity of electrorefining and electrowining in both aqueous electrolytes and molten salts are shown. The impact of energetic parameters, such as cell voltage and current efficiency on the economic justification of the electrolysis process is analyzed. It is emphasized that electrolysis is considerably cleaner technology than

When God gave humankind dominion over the earth he may not have known exactly what we would be able to do with it. The technical capacities to which the production and reproduction of our everyday life have given rise have grown at an astonishing and, it seems, ever-increasing rate. The instruments that we use to do work on the world have become sharper and more refined, and the implications of human interventions in the nonhuman environment are much more far-reaching than could have been imagined even forty years ago. It has become something of a cliche to say that our technical abilities hav

Abstract:

According to the International Energy Agency (IEA), only a tiny fraction of the full potential of energy from biomass is currently exploited in the world. Biogas is a good source of energy and heat, and a clean fuel. Converting it to biomethane creates a product that combines all the benefits of natural gas with zero greenhouse gas emissions. This is important given that the methane contained in biogas is a more potent greenhouse gas than carbon dioxide (CO2). The total amount of CO2 emission avoided due to the installation of biogas plants is around 3380 ton/year, as 1 m3 of biogas correspond

Abstract:

Higher education institutions are increasingly pursuing sustainable development goals in engineering and technology education. The concepts related to operations, production, and consumption continue to gain importance and significance for engineering students. In the engineering profession, the incorporation of sustainability means integrating environmental, economic, and social factors into the evaluation of design processes, products, and services. Therefore, it is necessary to develop an engineering program that along with the technical content, also fosters a critical sense regarding the

Abstract:

Research for new solutions in the field of wood-based materials and possibilities of their refinement is prompted by both market needs and increasingly restrictive environmental regulations. Many opportunities in this area are created by modern industrial technologies and constantly improved varnishing products as well. The observed trend indicating the usage of increasingly advanced technologies for the refining of wood-based materials in plants producing these composites confirms such activities and it creates new market opportunities. The correlations between the consumption of varnishing m

Abstract:

Concrete as the one of the most used material in civil engineering has also a very high negative environmental impact. In recent years’ environmental parameters of all building materials become the most important aspect. Especially reduction of concrete is becoming a very hot topic around the word because it can lead to the reduction of environmental impacts especially the consumption of primary energy, primary non-renewable materials and CO2 production. Textile reinforced concrete (TRC) is one of the possibilities to reduce amount of concrete in the structures. It is possible to design very t

Abstract:

Concrete is one of the most widely used engineering building material. Using waste concrete to produce recycled aggregate applying in concrete has been highly valued in developed countries, and has achieved significant economic and environmental benefits. China's current large-scale urban construction and road network renovation throughout the country generated a lot of waste concrete, but the technology about the recycled concrete is not widely used. In this paper, from the use of recycled concrete technology, production costs and environmental benefits and other aspects of social, evaluated

Abstract:

Food security and environmental issues have become global crises that need transformative solutions. As livestock production is becoming less sustainable, alternative sources of proteins are urgently required. These include cultured meat, plant-based meat, insect protein and single-cell protein. Here, we describe the food safety aspects of these novel protein sources, in terms of their technological backgrounds, environmental impacts and the necessary regulatory framework for future mass-scale production. Briefly, cultured meat grown in fetal bovine serum-based media can be exposed to viruses

Abstract In recent years, we have witnessed very frequent natural disasters such as earthquakes, floods, landslides, storms and similar. In most cases, disasters are caused by geological factors, especially geobarriers. Geobarriers threaten the life and works of man or reduce the effectiveness of the construction and operation of technical works, or harm the environment by negative anthropogenic influences. An important task in assessing the technical and environmental aspects of particular engineering activity is to assess the impact of constructions on the production and protection of the en

Abstract:

Silica fume (SF) has become an environmental mineral admixture in the production of high-strength and high-performance concrete in modern concrete engineering. Through compacting all components and pozzolanic reaction, obvious mechanical enhancement of concrete is observed in the aspects of compressive strength tensile strength, elastic modulus as well as fracture toughness. Further more, durability improvement of silica fume concrete such as chloride-ion penetration resistance and chemical attack resistance are reported accordingly.

Biodiesel obtained from vegetable oils as an alternative fuel for diesel engine is becoming increasingly important. The biodiesel quality and yield are affected by the properties of the oil used. The properties of the oil vary from region to region depending on the nature of the soil in which oil crops are cultivated, agricultural practices, rainfall etc. In this study the raw oil from Jatropha Curcas seeds grown in the western Ghat section of South India was tested for its physiochemical properties to determine its suitability for biodiesel production.

Abstract:

Wine production in South Africa is delocalised, with numerous small-to-medium sized producers within several regions within the Western Cape. Whilst adapting to new technological changes, producers have to respond to pressure from consumers and governments regarding the environmental consequences of winemaking, especially water usage and pollution. To date, no systematic analysis integrating the various aspects of winemaking in South Africa has been done. This study assessed both physical inputs and outputs. A detailed questionnaire was developed to broadly assess these parameters and was subm
