OUR TECHNOLOGY

HOW DOES ACTIVATION WORK?

'Activation' is the thermal or chemical processing of charcoal or biochar (i.e. high carbon content solid materials produced from organic materials) to both create new pores and increase the size of existing pores. By activating, both the total internal surface area and the average pore size of the raw material is increased dramatically, creating 'activated carbon'.

Traditionally, activation is carried out through either physical methods (steam at temperatures greater than 800C) or chemical methods (strong acids or bases). Both of these methods impart very high capital costs (due to material constraints associated with high temperatures and/or corrosive materials), high operating costs (heating requirements, long reaction times, chemical handling), and are environmentally unsustainable.

LTA PROCESS

Our revolutionary low-temperature activation (LTA) process completely changes the approach towards activated carbon production. Requiring only very low temperatures and minimal additional materials, benefits include:

         Little to no additional heating requirements.

         Fossil-fuel avoidance.

      ✓   No on-site water or harsh chemical requirements.

         Reduced CAPEX due to low material impact.

      ✓   Reduced OPEX due to self-sustaining process.

      ✓   Additional environmental benefits.

      ✓   Ability to utilise cheap and abundant biomass wastes.

REGENERATION SERVICES

Our LTA process can also be used to regenerate spent or saturated activated carbon. We are currently carrying our trials and scaling our regeneration capabilities and will ultimately be able to offer cost-effective and low footprint regeneration services.
