Bottom ash - MSWI-WWT-SLF - waste gypsum (market for)

The activity generating the emissions is market for bottom ash, MSWI-WWT-SLF, waste gypsum. The reference product is bottom ash, MSWI-WWT-SLF, waste gypsum. Bottom ash, MSWI-WWT-SLF, waste gypsum is a solid waste under the category of industrial wastes. It is generated in municipal solid waste incineration (MSWI) of sewage sludge (with 70% water) that in turn is generated during wastewater treatment (WWT) of leachate from the sanitary landfilling (SLF) of waste gypsum. bottom ash, MSWI-WWT-SLF, waste gypsum contains the following fractions: 100% bottom ash. By the database default (and per unit of reference product),bottom ash, MSWI-WWT-SLF, waste gypsum has 11.1% water on wet mass basis (88.9% dry matter) and Carbon present is of only fossil origin (0.04% on a dry matter basis). It has no heating value.
