This monograph especially emphasises the importance of the scope, by which forest fires, from year to year endanger the environment, including casualties. Fire seized areas in 2000 in Europe only were over 920,000 ha. Cases relating to relatively small locations, but which burned in unsettled areas, are often unidentified, because the satellite sensors have limited possibilities in the view of the size of the area they can detect. It is similar to those situations on the fires with relatively short temporal range, and during that interval thick clouds are above such area for example and other admixtures stirring the atmosphere. It is necessary to point out that all those fire seized places, spatially limited on smaller localities, often cause fire spreading by their wideness and a sort of a plant mass, relief and geologic surface, humidity and precipitation or by suitable combinations. On the other side, especially in the last few years, we are witnesses to events when fire has seized tens of thousands hectares just in a "wave", also penetrating through the urban areas.

CO2 capture from gaseous effluents is one of the great challenges faced by chemical and environmental engineering, as the increase of CO2 levels in the Earth's atmosphere is endangering the support of living species on this planet and might also be responsible for dramatic climate changes. Several capture technologies actually exist although the only proven and mature technology is, currently, chemical absorption using aqueous amine solutions, which still poses several technological and operational problems. Other concurrent technologies, such as adsorption and membrane, are in a less developed stage and require considerable research efforts to be viable industrial processes. Nevertheless, several alternatives exist for CO2 reutilisation as this is an abundant carbon source that could be easily used as a raw material for other carbon based raw materials, fuels and polymers. This book explores the problem of CO2 emissions and sequestration technologies, with a focus on recent scientific developments.
