Process Heat Recovery
Capturing lost energy to power the next generation of clean industry
The cleanest energy is the energy we stop wasting
PROBLEM: High-Grade Heat Lost in Industrial Processes
Every metallurgical process generates thermal energy — and most of it escapes unused.
Across kilns, dryers, and roasters, this means millions in fuel loss and significant CO₂ emissions.
TENSION: The Cost and Carbon Burden of Waste Heat
Process heating accounts for over 50% of the total manufacturing energy use.
Even a 10% gain in recovery efficiency can save billions of dollars and cut megatonnes of emissions.
Applications (global throughput):
Spodumene 1.3 Mtpy
Phosphate 223 Mtpy
Hydrated alumina 133 Mtpy
Nickel laterite 1.5 Mtpy
Copper conc. drying 21 Mtpy Cu
Soda ash 70 Mtpy
Lithium carbonate drying ~687 ktpy LCE
Waste valorization:
Fly ash ~780 Mtpy
Bauxite residues ~155 Mtpy
E-waste ~57 Mtpy
Spent catalysts ~1.2 Mtpy.
SOLUTION: Closed-Loop Indirect Heat Recovery
GEOMEGA’s indirect heat recovery systems capture high-temperature energy in a sealed, closed-loop unit integrated with existing equipment.
The system recycles up to 80% of total heat input, lowering both operational costs and carbon intensity.
KEY ADVANTAGES
80% heat recovery
Works across wide temperature ranges
Fits direct and indirect kilns
25% CO₂ intensity reduction potential
PAYOFF: Energy Efficiency that Pays for Itself
Recover heat, cut emissions, and turn waste energy into measurable ROI.
Every recovered megawatt strengthens both the bottom line and the planet.
