An Industry Overview of Textile Manufacturing

Not all textile manufacturing industries produce hazardous waste. If, however, you use hazardous solvents and materials containing toxic chemicals, you might be subject to Resource Conservation and Recovery Act (RCRA) requirements covering the generation, transportation, and management of hazardous waste.

The following textile manufacturing industry segments are covered by this summary:

Hazardous Wastes from Textile Manufacturing

Most of the hazardous waste generated by textile manufacturers results from the use of solvents. Solvents are used in:

In addition, solvents are used to clean machinery such as rollers and spinning machines used in textile manufacturing. Spent solvents are listed hazardous wastes. In addition, tetrachloroethylene, trichloroethylene, benzene, and ethylene dichloride are included in the recently expanded Toxicity Characteristic. Insecticides and disinfectants also sometimes contain Toxicity Characteristic chemicals such as cresols, chloroform, and carbon tetrachloride. Wastewaters or other process wastes containing these chemicals are hazardous if they fail the Toxicity Characteristic Leaching Procedure (TCLP) test.

Table I lists general processes/operations that use hazardous materials and that might result in the generation of hazardous waste. If you generate 100 kilograms (220 pounds or about half of a 55-gallon drum) or more of hazardous waste per month, you must fill out a Uniform Hazardous Waste Manifest when you ship the hazardous waste off your property. The Manifest requires the proper Department of Transportation (DOT) description for each waste. Table 2 lists proper DOT shipping descriptions for a number of wastes that are potentially generated during textile mill operations. Table I and Table 2 are not comprehensive lists. If you suspect that you generate a waste that is not included in this summary, contact your state hazardous waste management agency or EPA Regional office for assistance.

Waste Minimization

An effective waste minimization program can reduce the costs, liabilities, and regulatory burdens of hazardous waste management, while potentially enhancing efficiency, product quality, and community relations. Waste minimization techniques that can help you reduce the amount of hazardous waste that you generate include:

Training and supervision of employees implementing waste minimization techniques is an important part of your successful program. Call the RCRA/Superfund Hotline toll-free at 800-4249346 (or TDD 800-553-7672 for the hearing-impaired) for waste minimization information and publications.

Toxicity Characteristic constituent. Any waste that results in a TCLP leachate containing a Toxicity Characteristic constituent equal to or above regulatory levels is hazardous.

  1. These descriptions may change given variations in waste characteristics or conditions. Note that the DOT shipping name, hazard class, and UN/NA ID number do not directly correspond to RCRA hazardous waste categories.
  2. A flammable liquid has a flash point less than 100 deg. F.
  3. A combustible liquid has a flash point between 100 deg. F. and 200 deg. F.
  4. NOS - not otherwise specified.
