Caffeine is a natural substance that is present in the leaves, seeds and fruits of more than sixty plant species worldwide. Many food and beverage products made with these ingredients inherently contain caffeine. In addition, caffeine is sometimes added to foods and beverages during the manufacturing process in order to enhance flavour, or in the case of medications, to enhance efficacy.

There are three main methods for decaffeinating coffee and tea:   

  • Water Extraction Process
  • Carbon-dioxide Decaffeination
  • Solvent Decaffeination

Chemviron has adapted specific activated carbons for each of the decaffeination methods shown above. In addition, the spent carbon can be recycled by thermal reactivation.

Granular activated carbon

Chemviron has developed products that are specially designed for optimum removal of caffeine with minimal loss of flavor and product components (selectivity).

Reactivation services

Chemviron can offer safe and economical spent carbon handling and thermal reactivation in conjunction with fresh carbon supply and provide personnel and equipment to perform the carbon exchange on a turn-key basis.


Chemviron can bundle the performance advantages of activated carbon with equipment (service or purchase) and related services, to provide a full turnkey solution to decaffeination.
