Abstract
A ceramic for construction or technical applications, composed of at least one of Municipal Solid Waste Incinerator Bottom Ash (MSWIBA) and other recycled industrial solid waste and different methods of forming such ceramics. Various techniques illustrate how ceramics are formed using at least one of extrusion shaping, dry powder compaction and agglomeration, any of which can be preceded by a pre-treatment process of received feedstock.
Claims18
A method of producing a ceramic product comprising:
- receiving as a first component material a first feedstock;
- receiving as a second component material a second feedstock;
- combining the first and second component materials with water to form at least one of (1) an extrudable paste and (2) a granulated mixture;
- forming a green body from the at least one of (1) the extrudable paste after extrusion and (2) the granulated mixture;
- drying the green body;
- firing the green body to form the ceramic product;
- and
- cooling the ceramic product, wherein
- the first component material is pretreated Municipal Solid Waste Incinerator Bottom Ash (MSWIBA);
- the second component material is Unfired Raw Ceramic Material (URCM) powder;
- and
- the MSWIBA, URCM powder, and water are substantially free of organic substances.
