Waste Designation Decision Matrix - Sole Active Ingredient

This is the waste designation decision matrix provided by the Small Business and Local Government Assistance Program to aid businesses in deciding how certain wastes must be handled.

This matrix is provided as an assistance tool. It cannot be used as a substitute for following applicable city, state, and federal laws.

Does the discarded or expired chemical product have a sole active ingredient?YES NO

Sole Active Ingredient

An important requirement of this decision is whether or not your discarded chemical product is the "sole active ingredient" of the waste. Examples:

  1. Your product (a pesticide) has the ingredients listed as: 10% Aldrin and 90% Water. In this case, the product is probably Aldrin as the sole "active" ingredient, so the answer is "yes."
  2. Your product (a solvent) has the ingredients listed as: 10% Toluene, 30% Acetone, and 60% inactive ingredients. In this case, you have TWO active ingredients, so the answer is "no."
