Breakthrough DES Application

23 Nov 2020

Successful completion of proof-of-concept study

Descycle is delighted to announce a significant milestone for the Company, as it has completed its proof-of-concept study (the “Study”) on the uses of its novel chemistry, DES, for recycling metals from e-waste.  



  • The Study demonstrates the high efficiency of the process for recovering metals, with a 99% proven metal dissolution;

  • A significant number of metals have been recovered successfully from e-waste using DES, including; copper, gold, silver, palladium, tin and nickel;

  • The DES solvents operate at low temperatures and are non-hazardous;

  • When compared to the current carbon intensive methods used, DES is a significantly more sustainable solution.


About DES

DES has the potential to disrupt the rapidly growing e-waste recycling sector, due to its innovative, superior technology. Implementing the DES process into existing recycling operations will have low capital expenditure, and will increase metal recoveries in a more environmentally conscious way than existing processes.


Leo Howden, Descycle Managing Director commented: “We are delighted to have completed the Proof-of-Concept Study on our DES process, and equally pleased that it has proven our initial predictions as to the important and disruptive role that it could play in the future of e-waste recycling. The Study has proven the high level of efficiency of DES in recycling a large number of metals, as well as demonstrating the high levels of recoveries, which are superior to current metal recycling processes. We look forward to updating our stakeholders as we progress towards a full Feasibility Study, which we hope to complete over the next few years, to further prove our concept.”
