Process for Preparing a Ceramic Article Containing Sludge
The invention relates to a process for the preparation of a ceramic article containing industrial, domestic or natural sludge, the ceramic article, and treated domestic or natural sludge suitable as raw material for the production of the ceramic article. The sludge (which definition excludes digestate that is obtained from a Municipal Solid Waste (MSW) process comprising liquefaction of the organic fraction of MSW by addition of one or more enzymes) has been pretreated by a process comprising the optional step of drying the sludge to a moisture content of at most 10% by weight, resulting in dried sludge, and heating the sludge or dried sludge in a spouting bed incinerator and reducing the content of organic matter to less than 5% by weight. The invention furthermore relates to a process wherein the pretreatment comprises using the domestic or natural sludge as a food source for larvae.
