Prior to disposing of spent garnet, please review applicable local, state and federal regulations.  Although BARTON abrasives are classified as non-hazardous, it is the responsibility of the waste generator to ensure that spent materials are disposed in accordance with applicable solid waste regulations.  Depending on the waste generation process, additional testing (i.e. Toxicity Characteristic Leaching Procedure, or TCLP) may be required to accurately assess the proper waste classification.
