IES Recycling

Processing

We group gases to be recycled into four categories; Inerts, Flammables, Acid/Alkaline/Oxidizer and Other. Recycling options for each group are as follows:

A. Inerts, such as nitrogen, helium, and argon. Higher value and rare gases are consolidated into new cylinders using diaphragm compressors to eliminate any contamination from the process. IESR in our own operations uses gases such as nitrogen and oxygen, or they are directed to local commercial gas companies with a certificate of analysis for reuse.

B. Flammable gases, such as propane are consolidated and directed to local propane distributors. Gases such as methane and hydrogen are typically reused for their heat value.

C. Acid/Oxidizer/Alkaline gases such as chlorine and ammonia are typically consolidated into bulk containers. We typically recycle these materials in municipal wastewater treatment and agricultural settings.

D. IESR recycles specialty gases and materials such as chlorofluorocarbons (Freons) through specialized chemical companies that use these materials. Although we cannot accept every type of specialty gas, IESR maintains recycling outlets for many fluorinated and exotic materials.

Cylinder handling operations for all types of gases are done using unique, state-of-the-art equipment designed, developed, and in many cases, patented by IESR personnel. Managing deteriorated containers or those with inoperable valves is done safely and efficiently using specialized containment and access systems. We continuously monitor air quality throughout our storage and processing areas in the Data Center.

We maintain gas scrubbing equipment to safely manage residual quantities of material that do not qualify for recycling. In addition, if we receive material that is not appropriate for recycling due to contamination or other reason, it is redirected to a permitted TSDF for disposition.
