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.
Claims21
A method of encapsulating waste material, comprising the steps of:
- mixing said waste material with a thermosetting binder to form an admixture thereof:
- enclosing said admixture with thermoplastic resin sheet material;
- and,
- applying heat and pressure to said admixture and said enclosing sheet material until they are respectively transformed into a substantially rigid agglomerate sealed with an outer coat of fused sheet resin.
A method of encapsulating waste material, comprising the steps of:
- providing a mold;
- coating the interior of said mold with thermosetting polyester resin--chopped glass fiber;
- transferring said waste material into said coated mold;
- coating the top of said waste material with thermosetting polyester resin--chopped glass fiber;
- and,
- applying heat and pressure to said waste material and said thermosetting polyester resin--chopped glass fiber until said waste material is sealed with an outer coat of fused thermosetting polyester resin--chopped glass fiber.
