We are working on the effective utilization of precious iodine resources, the production regions of which are diversified through the recycling operations where the 3R technologies are taken into consideration.
We are executing recycling operations of iodine and various useful elements by applying efficient recycling processes where our many patented technologies, equipment and long years of experience are used.
We promote recycling operations jointly with our users and we aim to build the efficient iodine recycling systems between the manufacturers and the users.
What are the iodine recycling operations?
We at GODO SHIGEN have been among the first to respond to the customers' economic efficiency and the needs for environmental restrictions since the 1960s, working on the recycling of iodine from the used solutions containing iodine, and established various treatment methods.
We regard iodine as one of the precious natural resources and strive for the recycling operations by using the state-of-the-art technologies that are friendly to the environment.
In 1992, we established the comprehensive iodine recycling technology based on our own high-temperature decomposition treatment technology (patent granted) where our accumulated know-how are fully utilized. Thus, we have established the efficient integrated manufacturing system covering the phases of raw material iodine manufacturing, iodine compound manufacturing and recycling of iodine.
We acquired industrial waste disposal operator permission and special management industrial waste disposal operator permission for iodine recycling , thereby responding to the requirements of customers.
Recycle Raw Material and Evaluation Process
The used materials containing iodine, which are collected from various fields, will be accepted by us. And the components and the treatment methods are evaluated by utilizing the accumulated analysis technologies, discussions with the generation cause party are conducted regarding the recycling method, and off-take price as the recycle raw material is calculated. In addition, we will accept the proposal for the integrated circulation service covering the sales of iodine products up to the off-take-of used recycle raw materials.

Iodine Recycling Equipment
We have established the integrated production system, which is capable of executing all manufacturing phases from the extraction of iodine to commercialization of the product.
High-temperature Decomposition Furnace
The recycle raw materials containing organic iodine compounds are thermally decomposed in the high-temperature decomposition furnace to collect iodine.
Recycle Instrumentation Room
The high-temperature decomposition furnace and the electrodialysis device are controlled and monitored by CPUs, thereby ensuring safe operations.
With this equipment, it is also possible that iodine is selectively extracted from recycle raw materials to manufacture hydroiodic acid and the acid is converted into various iodine compounds.
