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...

Cement production is an energy-intensive process. Utilisation of fossil fuels is common practice in the cement industry around the world. Alternative fuel substitution rates increase every year. More specifically, 18 % of the fuel used by the European cement industry in 2006 consists of alternative...

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...

Local communities may experience flood events with devastating damages and economic losses. This work presents the application of an integrated method for flood loss estimation at the watershed level. The one-dimensional hydraulic model MIKE 11 was used to simulate the physical process of a flood...

In this article, the technical feasibility of various commercial adsorbents (activated carbon, clinoptilolite, and their mixture) for removal of Cr(total) ions from waste printing developer has been represent. Experimental tests were performed in laboratory batch mode. The adsorption data were...

Municipal Solid Waste (MSW) management is the field of science which explores and evolves strategies minimizing the final amount of wastes delivered to landfills and reducing the corresponding pollution related to all stages of treatment and collection. In the best practices of MSW the inherent...

One of the issues that have recently attracted increased attention from the hydrologic community is the impact of forest fires on the hydrological response of the once vegetated areas. This study presents the investigation of wildfires impact on the hydrological response of the small scale...

The present study deals with the problem of soil contamination risk assessment for a region being actively impact by the routine production of Kremikovtzi metallurgical plant near Sofia, Bulgaria. Although the production is now cancelled, the soil pollution is present and needs careful assessment...

Nitrogen oxide (NOx) and sulphur dioxide (SO2) emissions produced by the combustion of fuel in stationary sources, such as power stations, industrial heaters or cogeneration plants, cause significant environmental problems. Selective catalytic reduction (SCR) is a well established process for the...

Floods are natural disasters that pose a direct threat to human life and often cause significant economic loss. River floods are caused by heavy and/or prolonged rainfall, causing rivers and streams to overflow and sometimes also burst dams or levees. Forest fires increase the risk factor to which...
