ABSTRACT:
A method for disposing of waste material employs an agglomerate formed by molding an admixture of waste material and thermosetting binder. The use of a thermoplastic resin sheet in conjunction with the agglomeration mold promotes the safety of the molding process. Dust and mold leakage is abated and it subsequently yields a resin coated agglomerate that is safe for handling. The performance of the agglomerate is enhanced by formation of a coating of resin chemically bonded onto its surface. The performance of the agglomerate may be further enhanced by the formation of a seam-free thermoplastic resin jacket over the resin coated agglomerate.
