Abstract
A method is disclosed for processing waste glass strands and/or fibrous filaments which are produced in the course of operating a glass fiber forming plant for subsequent reuse as batch ingredients for a glass fiber forming process. The method described involves controlled thermal treatment of the waste glass strands and/or filaments to produce particulate glass which can be recycled to a fiber glass forming furnace. The reprocessing of waste glass strands and/or filaments reduces substantially the raw material cost involved in feeding glass batch ingredients to a glass fiber forming operation. Apparatus for accomplishing the reprocessing of the waste glass filaments and/or strands in accordance with the method disclosed is also described.
