Environmental pollution and its effects on living matter
The present knowledge of elements essential for life is summarised. Pollution of air, water and soil can modify the availability of elements essential to living matter. Because of narrow range of adequacy for most species this can result in different abnormalities. Among human activities which mobilise large amount of elements, a significant role is played by energy production and ...

Problems of energy conservation and environmental impacts of energy production and consumption in Slovakia
The current situation of the Slovak energy sector and its development since 1990 (Gross Domestic Product, primary energy sources, final energy consumption, energy intensity, electricity intensity, electricity consumption) is presented. A marked dependence on energy imports explains the necessity for energy conservation in Slovakia. Energy intensity in Slovakia is steadily decreasing; still there ...

On the relationship between risk control and risk potential for major hazardous industries in the EU
Technological progress is directed towards fulfilling human needs for development and progress. At the same time, the detriments or accidental risks arising from the use of specific technologies cannot be avoided. Risk-informed methods provide various qualitative and quantitative measures that can significantly support consistent decision making on managing accidental risks related to a specific ...

Use of an energy-saving concept to assess life-cycle impact in engineering
Energy and environmental issues are worldwide concerns in the 21st century. The authors propose that the best way to solve the energy-use problem is to account for all of a product's energy consumption information at the beginning of product design. Therefore, with the objective to promote energy-saving throughout the entire life cycle of general products or systems, the authors develop a new ...

Thermophilic sludge digestion - A perfect fit in cradle-to-cradle and energy neutral sewage treatment
Verstraete & Colsen It is not the scienctific discovery alone: it is the economic implementation of the technology that allows its breakthrough! The Case WWTP’s in NL : 1.500.000 tons sludge per year costs : 330 € / ton Can we turn this challenge into an economic operation? (via energy production and C2C nutrient ...

Ethanol from sugar beet in The Netherlands: energy production and efficiency
Prospects for ethanol production from sugar beet in The Netherlands have been analysed using measured production data from two experimental farms and literature on beet to ethanol conversion. The analyses include beet cultivation and harvesting, transport to the factory, conversion into ethanol and delivery of the ethanol to distribution points. Under the prevailing conditions, ethanol production ...

LCA of innovative technology for energy production from automotive Shredder Residue
Automotive Shredder Residue (ASR) is a problematic waste material remaining after shredding and recovery processes of End of Life Vehicles (ELV). Its heterogeneous grain size and composition make it difficult its recovery or disposal. While ASR accounts for about 20‐25% of the weight of an ELV, the EU's ELV Directive (2000/53/EC) requires that by 2015 a minimum 95% wt. of an end‐of‐life ...

Evaluation of municipal solid wastes (MSW) for utilisation in energy production in developing countries
In countries such as Ghana, which are still undergoing restructuring in their economies, low-cost energy supplies are most vital for development initiatives and may not only be the main constraint to their economic growth, but a principal source of conflicts in this century. But whether a meaningful and sustainable economic growth would be achieved or not rests exclusively on the removal of these ...

Alternatives for energy production in aerobic wastewater treatment facilities
Using technologies such as anaerobic digestion for energy generation from wastewater demands a change in infrastructure that several treatment works are not prepared to immediately implement. This works explores the use of energy production technologies to increase the sustainability of conventional aerobic wastewater treatment plants. The first option considered sludge (a by-product from ...

Soil is a non-renewable resource. Its preservation is essential for food security and our sustainable future
Soil is a finite resource, meaning its loss and degradation is not recoverable within a human lifespan. As a core component of land resources, agricultural development and ecological sustainability, it is the basis for food, feed, fuel and fibre production and for many critical ecosystem services. It is therefore a highly valuable natural resource, yet it is often overlooked. The natural area of ...

Quantifying the robustness of optimal reservoir operation for the Xinanjiang-Fuchunjiang Reservoir Cascade
In this research we investigate the robustness of the common implicit stochastic optimization (ISO) method for dam reoperation. As a case study, we focus on the Xinanjiang-Fuchunjiang reservoir cascade in eastern China, for which adapted operating rules were proposed as a means to reduce the impact of climate change and socio-economic developments. The optimizations were based on five ...

How to Consistently Blend Biomass
Prior to 2020, Drax, a British power supplier, purchased fuel pellets based on volume. They learned during that time that not all pellets are created equal. The company was paying the same price for fuel no matter its BTU value. This meant the company was paying more per BTU in some shiploads than others, and the practice disincentivized suppliers from optimizing their pellets. Thus, in 2020 Drax ...

Energy related environmental impact reduction opportunities in machine design: case study of a laser cutting machine
Energy consumption is responsible for a substantial part of the environmental impact generated by industrial production (Gutowski et al., 2006). Currently, minimising the energy consumption is hardly a priority for many machine designers, since they concentrate primarily on improving functionality, accuracy and safety. Nevertheless, alternative machine designs with improved energy consumption are ...

Further considerations on WAsP, OpenWind and WindSim comparison study: Atmospheric flow modelling over complex terrain and energy production estimate
This paper analyses Brazil’s most used wind assessment computational tools: WindSim, OpenWind and Wind Atlas Analysis and Application Program (WAsP). Each program produced a Wind Resource Grid (WRG) data base – through different methodologies – utilizing the same 5 anemometric towers, elevation grid and roughness map to generate it. The turbine layout was kept the same during all simulations and ...

On eco-efficiency and sustainable development in Estonia
The basic idea of sustainable development is a firm understanding that all resources, renewable as well as non-renewable, are limited. Human activities should not exceed the buffering capacity of the earth's ecosystems and the replenishment potential of material cycles. Use of non-renewable, mainly mineral, resources should be kept at the minimum possible level, postponing the depletion of ...

Smco magnets facts
Samarium (Sm) magnets are rare earth magnets manufactured into two series. The first series is sometimes referred to as SmCo5 (Co means cobalt), which is usually a high energy product of about 18 to 22 MGOe. The second is the most commonly known as Sm2Co17, which is a higher energy product of about 22 to 30 MGOe. It combines 2 Sm atoms and Co atoms between 13 and 17. It is basically an alloy of ...
