What is the difference between Halogenated Hazardous Waste and Non-Halogenated Hazardous Waste?
Why must I keep them separate?

Halogenated and Non-Halogenate Waste Bottles
Labeled Halogenated and Non-Halogenated Waste . BDE


Halogenated Solvent Waste should consist of hydrocarbons that have halogen atoms (i.e. F, Cl, Br, I) bonded to them. Examples of halogenated solvents include dichloromethane (methylene chloride) and chloroform.

Non-Halogenated Solvent Waste should consist of hydrocarbons that do not have any halogen atoms attached. Examples of non-halogenated solvents include acetone, ethyl acetate, hexanes and toluene.

Earlham maintains these as separate waste streams in our reporting and disposal, as do most small colleges. Mixed composition halogenated/nonhalogenated solvent waste should be designated as "Halogenated." Composition of all wastes should be listed on the label in addition to the words "Hazardous Waste," and collection dates (i.e. 20% acetone, 20% hexanes, 40% ethyl acetate, 20% chloroform)
