Abstract: A foamed solid product characterized in that said product is produced and prepared by a continuos process comprising mixing water permeated municipal solid waste (MSW) with a solidification reagent, wherein said solidification reagent initiates a polymerization reaction with the waste and the polymerization reaction forms a rigid polymer matrix therein. In addition, the polymer matrix also expands in volume during the polymerization reaction to form a foamed, environmentally stable, recycled solid product.
