A composition for encapsulating solid waste or sludge comprising: an aqueous silicate solution in an amount between about 0.05 and 5 weight percent, said silicate solution comprising between about 5 and 15 percent potassium oxide and between about 10 and 30 percent silicon dioxide; and a fixative in

A composition for encapsulating solid waste or sludge comprising: an aqueous silicate solution in an amount between about 0.05 and 5 weight percent, said silicate solution comprising between about 5 and 15 percent potassium oxide and between about 10 and 30 percent silicon dioxide; and a fixative in an amount between about 5 and 100 weight percent, said fixative comprising a substantial portion of calcium oxide, wherein the weight percents are based on the waste or sludge being treated.
