“iGen 460A has demonstrated 90% virgin caustic reduction and 100% hazardous waste reduction.”



The first iGen unit the iGen 200 was designed to demonstrate the technology. It was proven to remove more than 200/lbs. per day of dissolved Aluminum from spent die cleaning caustic solution.

iGen 400M in Operation

The iGen 400M was constructed for an aluminum extruder in Corona, CA. The unit has been operating since January of 2017 and saving the client money on both new caustic and waste disposal.

iGen 330A, 560A, 750A and 990A

iGen has a unit for every size extruder, fully automated versions of the caustic regeneration system. One button operation of the unit now saves even more labor cost.

“The iGen system is saving our plant money every day. Its like magic!”
– Richard G.

iGen can provide a fully tailored solution to your caustic regeneration needs.  All we need is the following:

  • Number of cleaning tanks,
  • Volume and change frequency,
  • Make up batch mix.

US Patent 9,718,697 The iGen process is a revolutionary patented process. The iGen system safely and effectively regenerates sodium hydroxide from spent aluminum extrusion die cleaning caustic solutions. The system dramatically reduces virgin sodium hydroxide purchases and hazardous waste disposal. The resulting aluminum trihydrate (ATH) is removed from the system and iGen manages this material at no cost to the user.
