Identify Wastes for Fiberglassers

Common Wastes in Fiberglass Facilities

Many materials in a fiberglass facilities can be dangerous, if they are not properly handled. Below is a table that covers many of these materials. Click on links for more information.

Waste

Where / Why

Possible Waste Code

Absorbent materials, see Shop Towels Absorbents contaminated with dangerous waste become dangerous waste. Code depends on materials absorbed
Adhesives    
Foaming Agents    
Initiators & Catalyst    
Out-dated Materials, Spilled Materials or Wastes    
Overspray Solids, Trim-ends, & Cut-outs    
Paint, waste or expired, oil-based Ignitable if flash point is below 140°F

State-only dangerous waste, often, due to metal content.

 

D001
Spent Paint-booth Filters. Often characteristic-toxic dangerous waste due to trace metals or halogenated organic compounds. Filters should be tested. Test to determine waste code.
Reinforcement    
Resin Often dangerous waste because it is flammable and contains styrene monomer  
Release Agent Nonhazardous wax or a polymer coating  
  Often low flash point or chlorine content. Acetone, toluene, xylene, and various alcohols are flammable. Usually recycled.  
Sanding dust   Test to determine waste code.
Shop Towels/Rags Contaminated with Dangerous Waste Absorbents soaked with dangerous waste become dangerous waste.  However, non-dripping rags/ towels are not considered dangerous waste if they are:
  • Laundered at an appropriate facility
  • Stored in containers away from a source of ignition AND
  • Not mixed with other waste.

 

Code depends on materials absorbed. Not regulated as hazardous waste if properly accumulated and laundered.
Solvents    
Solvated or Residual Resin    
Sludge or “bottoms” from solvent still that recycles solvent Listed and often ignitable dangerous waste: Still bottoms from a still where the solvent blend contains, before use, 10% or more of solvents such as, toluene, and MEK. The mixture may also have a flash point below 140°F. Listed: F005
