Abstract
The present disclosure provides efficient and cost-effective methods for producing synthetic soil and synthetic stone from waste, including inorganic waste and organic waste, through a hydrolysis-polycondensation process.
Claims15
A method for producing a synthetic soil from wastes, the method comprising:
- (a) hydrolyzing an organic waste composition using a hydrolyzing composition to produce a biomaterial, wherein the hydrolyzing composition has a pH ranging from about pH 13 to about pH 14;
- (b) activating an inorganic waste composition using an alkaline activator to produce a reactive zeolite gel, wherein the alkaline activator has a pH ranging from about pH 13 to about pH 14;
- and
- (c) mixing the biomaterial with the reactive zeolite gel to produce the synthetic soil,
- wherein the hydrolyzing composition comprises alkali-activated red mud.
