Innovating Since 1992
2024
emew technology growth in applications and locations
Several new systems delivered to customers worldwide in e-waste, industrial wastewater, copper refinery bleed, silver, etc.
2023
Global expansion and new facilities
New offices were established in India, and Australia. Development lab was set up in Toronto to enhance research and development efforts.
2022
UAE fulfillment center
A fulfillment center was opened in the UAE to better serve customers worldwide, expanding emew’s global reach.
2021
E-waste technology tested, France
A new technology to effectively remove and recover copper from e-waste was demonstrated in France.
2018
Expansion into new applications
Copper powder, low-grade silver and gold. Also selenium (with our partner BQE Water).
2015
Expansion into wastewater treatment
The first hybrid emew technology system was installed at a semiconductor plant for copper removal and recovery, marking emew’s entry into the wastewater treatment sector.
2013
Innovative low ppm silver recovery by emew scavenger cells
The first emew Polish plant was developed for an existing customer for silver recovery, reducing silver concentration to less than 5ppm in the solution.
2011
Commercial tin recovery
emew expanded its technology to include commercial tin recovery with the installation of the first emew tin system in the USA.
2009
Copper-arsenide removal
The first successful controlled production of copper-arsenide for arsenic removal from refinery bleed was achieved using emew technology.
2008
Introduction of silver powder plant
The first emew silver powder plant was introduced, producing 9999-grade silver with a daily output of 500kg.
2007
First emew system for refinery bleed treatment at White Pine, MI
All the product from this plant meets one of the highest (B115) specifications for copper even when the electrolyte contained up to 28g/L arsenic.
2006
Launch of new-generation copper plant at Freeport, TX
A new-generation (larger cells and more effective flow design) emew copper plant was launched in the USA with Phelps Dodge (now Freeport), marking a significant technological advancement. The system replaced 14 operators with 2 and has been operating continuously since then.
2000
Invention of metal powder technology for automated harvesting
emew invented metal powder technology for automated harvesting and filed the patent W0 01/07684 A2.
1999
Expansion from copper to nickel
Technology and expertise were further developed to broaden from copper to nickel, with the installation of the first emew nickel system in the USA.
1996
Granting of several improvement patents
Several improvement patents were granted, including WO94/02663 and WO96/38602, covering innovations such as membranes and split sleeve harvesting technologies.
1992
Invention of vortex technology in Australia
The original patent for vortex technology was filed by Materials Research Pty Ltd on behalf of inventors Neil Barr, Robert Dedenus, and Patrick Treasure (original CEO of emew). This patent (International Patent No PCT/AU92/00052) was the first of its kind globally.
