The commonly accepted brine concentration practice in most Chinese Northern solar works is to pump the sea water into salt works and then let it go through a physical changing process of natural evaporation, condensation and crystallization, during which, weather factor and the soil nature have to...

Halide gases used in various industrial processes significantly contribute to the greenhouse effect owing to their high GWPs. In addition, the halide gases have high chemical stability and thus remain in the atmosphere for a long period. Therefore, effective treatment techniques of halide gases are...

Photocatalysis is a promising method for eliminating the volatile organic compounds emitted from various industrial processes because mild or ambient conditions are used. Titanium dioxide is commonly used as photocatalyst and ultraviolet light is utilized for decomposing gas phase pollutants. In the...

Disposing of plastic wastes to landfill is becoming undesirable due to legislation pressures, rising costs and the poor biodegradability of commonly used polymers. In addition, incineration meets with strong societal opposition. Therefore, recycling either mechanical or chemical, seems to be the...

Fly ash is an important industrial by-product that comes from the combustion of coal, for the production of electrical energy. In our country, only a small percentage is used for the construction of technical projects, while the rest is stockpiled, causing serious problems. Because of its great...

In the present work, wood and bone ash were used to remove metal cations from solutions. Cation-removal capacity of the ashes was analyzed by potentiometric titration. It was found that the capacity of wood ash was two times higher (37.3 meq g-1) than bone ash (15.2 meq g-1). Kinetics of metal ions...

The ENVIRON model estimates environmental impacts (positive, negative) from the introduction and use of Advanced Communications (AC); Information Society Technologies (IST) in industrial, commercial and business sectors in Greece. The model estimates effects on output, employment, income...

Electricity generation in solid fuel fired power stations is currently the main source of flying particulates and greenhouse gases emissions. Environmental pollution is expected to deteriorate dramatically in the coming century unless pollution abatement technologies for solid fuels energy...

Pollutants posing health risks to human health and to the aquatic environment often occur in drinking and surface waters, as a result of disinfection practices, agricultural and industrial activities, wastewater discharges. Toxic pollutants belong to different chemical categories, including...

Electricity generation is the single most important sector in which CO2 reductions are achievable, with advanced generation technologies available and the existence of a centralised production structure, if compared to the transport or the industrial sector. It is a market undergoing a radical...

Energy use in Greek Industry, fuel mix changes and contribution of major sectors from 1960 to 2004 are presented and analysed. Energy related air pollutant emissions are estimated and presented too. Energy use in Industry has shown a growing trend. Residual fuel oil was the predominant energy form...

Saltscapes are landscapes with a long lasting salt-making activity, thus embedded with a blend of salt-related characteristics that marked them physically, ecologically, economically, and culturally. This study, based on a broad survey, focuses on the changing atlas of saltmaking business and the...

Odour emissions are a major environmental issue in sanitary environmental engineering plants, due to the increasing number of complaints being made by the exposed population. The particular and complex nature of the substances considered to be the cause of the odour impact, their variability in time...

In recent years many researchers show a high interest in co-digestion, simultaneous anaerobic decomposition of a homogenous mixture of at least two biodegradable waste. Anaerobic codigestion is reported to offer several benefits over digestion of separate materials, such as increased cost-efficiency...

Biofuels represent a possibility to reduce greenhouse gas (GHG) emissions within the transport sector. In this context the sustainability of biofuels, especially so called 1st generation biofuels led to controversial discussions in the past. Biofuels from waste and residues represent a well suited...

The Ninth International Symposium on Salt (www.worldsalt2009.com) organized by China National Salt Industry Corporation, China Salt Association and many other salt organizations of the world was held in the Beijing International Convention Center on the 4-7 September 2009. It is the ninth in a...

The waste to renewable energy source has become a priority in the wastes treatment field. The research goal is not only the wastes destruction but also a better thermal energy recovery from the processes. The municipal solid waste presents a high heterogeneity degree from the dimensional point of...

The restrictions in availability of forest-based raw materials along with favourable environmental policies towards alternative sources of raw materials have forced corrugated packaging industry to shift towards recycled paper and other fibre sources such as non-wood and agro-residues. The...

According to the actual European context, including the development of risk free residential and industrial areas, the main demand lies in instant, accurate and elaborated information regarding environment quality and pollution risks. This paper presents a conceptual architecture for a versatile...

The objective of this study was set on three goals: (i) Chemical and radiological characterization and leaching properties of the mixture of fly and bottom ash, (ii) Chemical, radiological and mineralogical characterization of the Kastela Bay sediments, and (iii) Estimation of the influence of...

Organophoshorous pesticides are widely used in agriculture, because most of them are high effective and low persistent. Yet their increased usage has elicited extensive research into pesticide effects on non-target organisms, such as algae. Algae are of vital importance in the primary production of...
