Abstract
A method for the co-production of silica and at least one other useful industrial chemical such as ethanol, comprises the steps of: pre-treating siliceous plant matter derived from plants, such as horsetail weeds from the genus, to create a feedstock having exposed cellulose; placing the feedstock in a reactor containing a biological agent effective to break down the cellulose into at least one useful organic chemical reaction product and a silica-containing co-product; separating the at least one useful organic chemical product from the reactor; separating the silica-containing co-product from the reactor; and refining the silica-containing co-products into silica or other industrially useful silicon containing products. The biological agent may be an anaerobic thermophyllic bacteria, enzymes, or a co-mixture of enzymes and yeast.
