Recyclingtechnik: Fachbuch für Lehre und Praxis (German Edition)

Das Recycling von Altgeräten, Werkstoffen und anderen Materialien leistet einen wesentlichen Beitrag zur Ressourcenschonung, Schadstoffbeseitigung und Energieeinsparung sowie zur Reduzierung von Deponievolumen. Die einsetzbare Recyclingtechnik ist dabei eine grundlegende Voraussetzung für die wirtschaftliche Realisierung der Prozesse.

Solid Waste Management in the World's Cities: Water and Sanitation in the World's Cities 2010

In our speedily urbanizing worldwide society, sturdy waste administration may be a key problem dealing with all of the world's towns. stable Waste administration within the World's towns offers a clean standpoint and new information on one of many largest concerns in city improvement. utilizing the framework of built-in Sustainable Waste administration (ISWM), the document brings jointly exceptional study from 22 towns throughout six continents.

Analysis and Fate of Surfactants in the Aquatic Environment, Volume 40 (Comprehensive Analytical Chemistry)

An realizing of the destiny and behavior of natural chemical compounds, akin to surfactants, within the setting is a prerequisite for the sustainable improvement of human overall healthiness and ecosystems. As surfactants are being produced in large quantities, you will need to have an in depth wisdom approximately their lifetime within the setting, their biodegradability in wastewater therapy vegetation and in usual waters, and their ecotoxicity.

When the entire amount of the complex was removed on outgassing around 750°C, the carbon lost almost completely its capacity to neutralize alkalies, even though it still contained appreciable amounts of associated oxygen (cf. 4). 66 Their surface acidity, as determined by neutralization of sodium and barium hydroxides, was found to be close to each other as well as to the amount of CO2 complex contained in each sample. 69 studied the adsorption of ammonia and several amines on several charcoals and carbon blacks and found that the amount adsorbed was close to the amount of CO2 complex present on the carbon surface.

5). The strongly acidic groups neutralized by NaHCO3 but not by Na2CO3 were postulated as lactones. The weakly acidic group neutralized by NaOH but not by Na2CO3 was postulated as a group of phenols. The reaction with sodium ethoxide was not considered a true neutralization reaction because it did not involve an exchange of H+ ions by Na+ ions. , Ind. Engg. , 50, 1071, 1958. With permission. , in Advances in Catalysis, Vol. XVI, Academic Press, New York, 1966, p. 179. With permission. oxidation of the disorganized aliphatic carbon.

6). The base neutralization capacity decreased on evacuation, and the decrease at any temperature corresponded to the amount of CO2 evolved at that temperature. 8) as the temperature interval over which CO2 was evolved from the carbon sample. 8 Base adsorption capacity in relation to evacuation temperature. , Carbon, 16, 65, 1978. 74 suggested that the lactone exists in two tautomeric forms. The keto form explains the results obtained for monobasic carbons, and the enol form fits well with the dibasic carbons such as PVDC, PVC, and Saran.
