Introduction

REM offers pickup services for all chemical waste generated on the West Lafayette campus. A Hazardous Materials Pickup Request Form must be completed and submitted by the generator of the waste to initiate pickup services. Once the pickup request has been processed, REM staff will come to your lab to pick up the waste.

---

Pickup Procedures 

1. Prior to pickup, all waste must be placed in a designated area within the room where the waste was generated.
2. All waste must be placed in an appropriate container.
3. All containers must be capped and labeled.
4. Complete and submit a Hazardous Materials Pickup Request Form.

If unknown chemicals are present in your lab, please see the Unknown Chemicals page on the REM website for assistance.

All empty containers should be triple rinsed and either reused or thrown in the trash.

If you have questions regarding pickup procedures please call 49-40121 or refer to the Hazardous Waste Disposal Guidelines.

Hazardous Materials Pickup Request Hints 

Chemical Description:

• Spell out all chemical names. Do not use acronyms, abbreviations or formulas.
• The chemicals must be in percent form adding up to 100%. The percentages of each chemical should be accurate but can be rounded to the nearest whole number. For example, 0.01% Benzene can be conveyed on a pickup request as "Trace Benzene", or "<1% Benzene". The following is an example of a good chemical description: "Acetone 50%, Tetrahydrofuran 10%, Chloroform 20%, Acetic Acid 10%, Water 10%, Trace Silver".
• The description on the container label must match the description written on the pickup request exactly.
• When submitting trade products, read the description of the chemical components on the label, or request a MSDS from the manufacturer. This information will provide you with a proper chemical description for the product. You are responsible for providing REM with chemical descriptions or a MSDS.

Amount of Waste in Container:

Estimate as accurately as possible (i.e. +/- 10%). Use mass units for solids and volume units for liquids.

Spent or Useable:

The material is only useable if you are certain that the chemical is uncontaminated and can still be used for its intended use. Otherwise, consider it spent.

Physical State of the Material:

Solid, liquid and gas are the only designations that should be used. In general, keep solid and liquid wastes separate. If you have a mixture containing both solids and liquids, the rule of thumb is that if any portion of the waste flows as a liquid, call it liquid.
