Yava has developed a proprietary process that has the following characteristics:

  • Low capital costs—relies on readily available, reliable standard industrial equipment rather than custom designed processing equipment
  • Regeneration of reagents yields a closed loop with minimal discharges—and no toxic waste
  • Flexibility to use a variety of low cost, widely available feedstocks
  • Very small carbon footprint (Yava Alumina’s demonstration plant in Quebec will consume low cost hydro-generated electricity)
  • Capability to produce very pure HPA (99.998%) with target of 5N+
  • Ability to produce HPA with physical characteristics (e.g., particle size and distribution, density, porosity) to meet the exacting specifications of end-users

  • HPA is a huge growth story… the eyes of the car companies turn from time to time and they’ve landed at the moment on HPA.”–Toby Green, CRU International (global consultancy)
