Maximize Biogas Yield
Overcome Ammonia Inhibition with OTAR® Technology
Protect your methanogens and maximize biogas yield from Poultry, Food Waste, and Slaughterhouse feedstocks with OTAR-electric®.
Maximize Biogas Yield
Overcome Ammonia Inhibition with OTAR® Technology
Stop letting high nitrogen levels stall your anaerobic digester. Implement On-site Thermal Ammonia Recovery (OTAR®) to stabilize your process, increase methane production, and convert waste into high-value ammonium sulphate.
Is High Ammonia Killing Your Digester Performance?
Nitrogen-rich feedstocks are essential for high-yield biogas production, but as they break down, they release high concentrations of Total Ammoniacal Nitrogen (TAN). This leads to:
Inhibited Methane Production: Reduced biogas output and lost energy revenue.
Process Instability: Frequent “sour” digesters and costly maintenance.
Regulatory Hurdles: Difficulty meeting nitrogen discharge limits.
This is a critical challenge for facilities processing:
Poultry Manure & Litter
Cow & Dairy Manure
Slaughterhouse, Food waste, Food Processing Industry
Landfill & Municipal waste
OTAR® : A Proven Low-Carbon Solution
The Circular Economy Solution for Waste-to-Energy
The OTAR® platform is a modular, thermal stripping system designed to integrate directly with your existing AD infrastructure. By removing ammonia from the digestate, you unlock the full energy potential of your organic feedstock.
Boost Biogas Efficiency
Lowering ammonia levels allows for higher organic loading rates.
Energy Neutral Operation
OTAR® utilizes waste heat from your existing biogas engines (CHPs).
Resource Recovery
Don’t just treat waste—produce commercial-grade ammonium sulphate or ammonium hydroxide for use as fertilizer.
OTAR® at a Glance : Optimized for Thermal Resource Recovery
Our technology uses a low-temperature thermal process to move ammonia from the liquid phase to the gas phase. Depending on your site requirements, we offer several configurations:
Variant 3: Produces 40% concentration Ammonium Sulphate—ideal for direct agricultural resale.
Variant 4: Features advanced heat recycling for maximum thermal efficiency using CHP waste heat.
