DEEP EUTECTIC SOLVENTS
(DES)
A new and innovative class of chemistry with unique characteristics and capabilities
Why Develop DES?
​
Sustainable
Low-energy, non-toxic processing to produce low-carbon & low-impact metals
​
Affordable
Cheap, readily available, biodegradable, & recyclable solvents
​
Scalable
Low capital intensity and a small area footprint means the process can be scaled to small and large operations
What is a DES?
​
DES are combinations of two or more components which form a mixture with a melting point lower than that of each component - click for science
Metals behave differently in DES than in water-based systems
​
DES components (salts & organic compounds) are environmentally benign, and many are also biodegradable
Applications
DES - A Platform Chemistry
There are millions of possible DES formulations, with each formulation having different properties & attributes suited to a particular task.
DES formulations can be customised by adjusting the components and their ratios; creating the opportunity to tailor solutions for a wide range of metals

Yet To Be Evaluated
E-waste
Recycling
-
The World's fastest growing waste stream
​
-
Growing to US$82bn annually by 2030
​
-
Many critical and precious metals are contained within e-waste, making e-waste valuable but environmentally hazardous
​
-
DEScycle's technology has been developed as a disruptive & clean alternative to current high-impact & capital intensive recycling methods
