Recovery Fundamentals and Process

Recovering (recycling) iodine is environmentally and economically important because it is a scarce and limited resource.  For many years, iodine-containing byproducts were considered waste due to impurities in the byproduct mixture.

As iodine experts, IOCHEM saw an opportunity to transform this consideration and increase iodine supply by implementing the first US iodine recovery facility capable of processing iodine byproduct streams into market-ready, high purity iodine.

Our vision was simple – to reshape the way we think of iodine byproduct streams and to increase the availability of a rare and finite resource.

Recovery Materials and Methods

Iochem recovers iodine using a variety of methods, allowing recovery from:

  • Organically bound iodine
  • Iodine solids (wet cake)
  • Inorganic iodine solutions
  • Inorganic iodine solutions with organic impurities

Iochem is the premier location in North America for iodine recovery. We break down the impurities of the product and separate the contained iodine as a gas, which passes through a recovery system, is concentrated, and then processed into crude iodine. Although the refinement process is simplified compared to virgin iodine production, the recovered iodine produced is above 99.3% purity and often above the standard purity of 99.5%.

Common Industries using iodine and generating iodine waste streams:

  1. Pharmaceutical
  2. Biocides and Pesticides
  3. LED and Optical Polarizing Films
  4. Salts
  5. Human and Animal Nutrition
  6. Specialty Chemicals
