Abstract
Among others mono-incineration, co-incineration in a municipal incineration
plant, incineration in the cement industry, gasification, wet oxidation,
co-fermentation and application in agricultural are investigated. The
systems include the whole wastewater and sewage sludge treatment and
refer to 1 population equivalent (PE, 80 g COD/d). The evaluation of the
options takes account of environmental, economic and social criteria with
standardized cost-benefit scores. Disposal in a cement plant and monoburning
of the sludge with further treatment to recycle phosphorous are
more favorable compared to the other scenarios investigated.
