This paper presents an ecotoxicological evaluation of soil fertilized with biogas digestate (BD) or mining waste (MS). The study was performed under pot experiment conditions. BD was added at a dose of 1.5 and 3% to the soil. MS was applied at a dose of 10 and 20%. Samples were collected at the beginning of the experiment and after 180 and 360 days from the start of the study. In addition, a pa...

Application systems often need to react with certain actions whenever some preset conditions are satisfied. In many cases, the evaluation of these conditions takes long time, but some prediction of the results can be obtained rather quickly. In this situation, speculation may be a good idea. That is, the system takes predictions (speculation) to prepare (such as prefetch) for the possible react...

Biodiesel has an important role in the world of transportation and its existence is taken into account. So availability biodiesel fuel future will be difficult to eliminate must continue fulfilled. Therefore, it necessary innovate increase fuel. can made from biological materials includes renewable energy as a substitute for diesel oil. The production this study jatropha waste cooking oil raw m...

Biofiltration of waste gases is cost-effective and environment-friendly compared to the conventional techniques for treating large flow rates of gas streams with low concentrations of pollutants. Pulp and paper industry off-gases usually contain reduced sulfur compounds, such as hydrogen sulfide and a wide range of volatile organic compounds (VOCs), e.g., methanol. It is desirable to eliminate ...

There is a need for treatment technologies that can eliminate environmental problems associated with anaerobic lagoons. These technologies must be able to capture nutrients, kill pathogens, and reduce emissions of ammonia and nuisance odors. To meet these needs, a full-scale wastewater treatment plant was installed as a demonstration project on one of three 4360-pig (Sus scrofa) production unit...

Most solutions proposed for the looming shortage of primary care physicians entail strategies that fall into one of three categories: train more, lose fewer, or find someone else. A fourth strategy deserves more attention: waste less. This article examines the remarkable inefficiency and waste in primary care today and highlights practices that have addressed these problems. For example, delega...

Adiox is a state-of-the-art dioxin removal technology that has established itself as a cost-effective way to reduce dioxin emissions to the atmosphere. Adiox is a construction material in which carbon particles are dispersed in a polymer such as polypropylene. Several types of components such as tower packings for wet scrubbers, demisters (droplet separators) and dry or semi-wet fixed bed filli...

The utilization of bioelectrochemical systems for methane production has attracted increasing attention, but producing methane in these systems requires additional voltage to overcome large cathode overpotentials. To eliminate the need for electrical grid energy, we constructed a microbial reverse-electrodialysis methanogenesis cell (MRMC) by placing a reverse electrodialysis (RED) stack betwee...

Stone dust is a kind of solid waste material that is generated from stone crushing industry which is abundantly available. It is estimated that each crusher unit produce 15%-20% stone dust. Disposal of such wastes poses lots of geoenvironmental problems such as landfill disposal problems, health and environmental hazards. The best way to eliminate these problems is to make use such waste. Keepi...

Many industrial areas in the world, show increases in generating of wastewater nowadays. Industrialization is considered as the key factor for the development of countries in economic terms. The recognition that environmental pollution is a worldwide threat to public health has given rise to new initiatives for environmental restoration for both economic and ecological reasons. The best methods...
