Accelerate the
realization of a society that
will continue to use ground resources forever
The three promises to be realized by Emulsion Flow Technologies
To realize the promises
of Emulsion Flow Technologies
- Start up operation of EF plants
equipped with Emulsion Flow
Technology
for all resource recycling
processes around the world. - Undertake our initiatives as a rare
metal manufacturer to operate EF
plants to promote resource recycling
in small-scale regional markets.
Horizontal recycling and
perpetual circulation will be
realized with every EF plant
to
start operation, which will
accelerate our steps to achieve a
truly sustainable future.
Outline of the circular economy envisioned
There are no conventional technologies to produce rare metals in the quality sufficient to recycle to a module production level from raw materials collected through dismantling and sorting. We, EFT, have developed the world’s first solvent extraction technology that enables highly efficient and highly pure rare metal recycling. We enable “horizontal recycling” for resource circulation that reuses the used materials as raw materials for product production as well as “perpetual circulation” that does not rely on underground resources.
Material Processing: Solvent Extraction Process
Material Processing: Solvent Extraction Process
- 1Material
processing - The material processing process begins with the production of black mass, which is the raw material for material processing, as well as production of rare metals through the solvent extraction process and providing them as raw materials for manufacturing cells and modules.
- 2Black Mass
Production - After dismantling and sorting finished products collected through process waste and recycling, the finished products are discharged, dried, crushed, and pulverized to produce concentrated powder (black mass) containing rare metals.
- 3Solvent
Extraction - Solvent extraction is the central process in material processing for rare metal recycling. With the conventional process, products that were collected as waste were used as materials for roadbeds and so on and were never reused as products. This was due to the lack of highly efficient material processing methods. EFT has developed the world’s first solvent extraction technology that realizes highly efficient and highly pure material processing. By developing plant equipment with the technology that can handle mass production of battery-grade quality rare metals with 10 times the productivity of conventional products, we are able to supply quality materials that can be used in modules from finished products used around the world.
- 4Spoke
- Spokes are distributed bases in the spoke-and-hub system. Batteries for EV vehicles weigh 500 kg each, and the waste from finished products is collected all over the country. Transportation efficiency is improved by turning it into black mass at the places where the waste is collected.
- 5Hub
- A hub is a centralized base in the spoke-and-hub system. Since the solvent extraction process can be performed continuously around the clock, the material processing efficiency is increased by transporting the black mass and collecting it at the hub for solvent extraction. EFT manufactures and develops plants that operate at a central hub function. In addition, we provide raw materials to cell and module manufacturers with the services for dissolution and impurity removal processes as the pre-processes of solvent extraction, as well as crystallization processes as the post-processes.
