Seghers’ ZEROfuel Option for Biosolids Treatment – Combining Drying and Fluidized Bed Combustion to Optimize Biosolids Thermal Treatment
Abstract:For some time, Western Europe has been faced with the two-fold problem of ever increasing biosolids production coupled with a decreasing number of land-based disposal options. One of the wealthiest regions in the world in terms of corporate and individual income, Western Europe's growth in industry and population has given rise to problems associated with waste disposal of all types. More specifically, with regard to municipal biosolids disposal, the limited amount of available farmland is simply not able to support the increased volume of biosolids. What little farmland is available is reserved for farmgenerated manure fertilizers. The obvious choice for biosolids disposal under such conditions would appear to be thermal combustion were it not for two problems: 1) Western Europe has become increasingly concerned about the environment and, in particular, air quality issues, and 2) Western Europe has always been faced with relatively high fuel prices, thereby creating cost problems associated with thermal treatment options.
