Iofina (LON:IOF) has commissioned its fourth and fifth iodine producing plants in the US following approval from the federal regulatory authorities.
Construction of the sixth plant based on its IOsorb technology, IO#6, is expected to be finished this quarter.
George Lantz, Iofina’s chief executive and president, said: "Our production teams have already started full-scale production operations at both plants and are pleased to be producing iodine at these state-of-the-art facilities.
This brings the number of plants currently in operation and online to five plants, a 150% increase over the fourth quarter 2013."
Last month, Iofina said it was carrying out an operational review assessing ways of improving the construction process as well as reducing the cost and time it takes to build the operations.
No new full-scale plants after IO#6 will be built until the review is completed in the autumn, the company said.
Iofina ‘s IOsorb technology extracts iodine from the brine recovered from onshore oil and gas drilling.
