Bygen’s Patented Low Temperature
Activation (LTA) Technology
Bygen’s Patented LTA - Redefining Activated Carbon Manufacturing
Bygen has developed the world’s first Low Temperature Activation (LTA) process - a revolutionary way to produce high-performance activated carbon from sustainable feedstocks with dramatically lower energy requirements and emissions.
For decades, the industry has relied on energetically expensive, high-temperature processes. Bygen’s LTA technology changes this entirely - delivering premium-quality activated carbon through a process that is smarter, cleaner, and more sustainable.
How LTA Works - The Bygen Difference
Our patented LTA process combines carbonisation and activation into a single, integrated system. Instead of relying on costly activation with steam or CO₂, LTA uses air and recycled off-gases from the initial carbonisation stage to activate at much lower temperatures than traditional methods.
Unlike other activation methods, the reaction at the core of LTA is exothermic - it produces its own heat, making the process largely self-sustaining and generating significant excess heat compared to conventional activation.

Why LTA Changes the Game:
-
World-first innovation: patented technology unique to Bygen
-
Ultra energy-efficient: reduced reliance on external fuel and high-temperature steam
-
Sustainable from the ground up: uses sustainably sourced biomass feedstocks; currently validated for soft biomasses such as almond shell and wood chips, with ongoing R&D to expand applicability to other feedstocks
-
Closed-loop gas recycling: minimises emissions and environmental impact
-
Consistent high quality: pore development optimised for superior adsorption
-
Performance stability: maintains adsorption efficiency over long deployment periods
-
Scalable and reliable supply: suitable for utilities, councils, and large-scale industrial operations
Environmental & ESG Advantages:
Bygen’s LTA technology has been independently validated as carbon-negative under ISO 14040, 14044, and 14067 standards.

-
Leading the way to a lower-carbon future in environmental treatment technologies
Whether for water purification, air filtration, gold recovery, or PFAS removal, Bygen’s LTA delivers exceptional adsorption performance while reducing environmental impact.
The Limitations of Conventional Activation
Traditional activation methods often rely on high-temperature steam or CO₂, making them energy-intensive, slow, and costly. These processes:
-
Require substantial external heat (for activation and steam generation)
-
Can take up to eight hours and require expensive reagents in the case of CO₂ activation
-
Are frequently split across multiple facilities, losing valuable heat between stages
-
Often release harmful off-gases without proper combustion
The result: high costs, high emissions, and low efficiency.
