Label Date April 16, 2020
From France
Maturity stage TRL 9 / CRI 2 - Commercial Trial Small Scale

To keep rare resources for the future generations and decrease the carbon footprint of gold applications, Daumet proposes to use gold differently thanks to an innovative and patented gold alloy presenting large similarities with pure gold. Daumet mix gold with tungsten, the hardest metal and the only one presenting the same density than gold. This ultimate gold alloy has properties common to pure gold. However, it is more resistant (mechanical, temperature...), cheaper and more sustainable because tungsten is more abundant in the Earth.

The Environmental Benefits

  • Capable of reducing the consumption of pure gold up to 114 tons per year
  • 30% less water pollution compared to traditional gold production
  • 20% less CO2 emitted in the atmosphere
  • Helps to reduce mining waste, deforestation and the loss of biodiversity related to traditional gold production

The Financial Benefits

  • Pure gold (45k€/kg) is substituted by tungsten which costs around 5€/kg
