Technology
The Ductor process offers an effective solution to allow the processing of high nitrogen wastes. Nitrogen is removed in a pre-fermentation prior to the biogas process to prevent nitrogen inhibition in the main fermenter. The recovered nitrogen liquid phase can be used as fertilizer, whilst the nitrogen-reduced slurry can be fermented in a standard anaerobic digester. The digestate is upgraded to fertilizer or soil improver.

More InformationAdvantages for Egg Producers:
A Ductor facility adjacent to your farm removes manure daily with dedicated trucks and a controlled traffic route, improving biosecurity and air quality in the barns, reducing flies, odours and storage requirements, and eliminating weather dependent land application, while a long-term agreement guarantees steady removal.
- Daily fresh manure removal, independent of weather and land application windows
- Improved biosecurity: reduced exposure to wild birds, rodents and insects, and reduced risk of cross contamination between barns
- Truck washing and inspection at the facility's own biosecurity station
- Less manure storage on the farm and fewer flies and odour issues
Haren, Germany
Our reference plant in Haren, Germany runs on a working biogas plant, produces in specification organic liquid nitrogen fertilizer Ductor High Nitrogen Liquid Fertilizer 5-0-0 and is registered for organic use in California, Washington, Oregon and Ohio.
Jalisco, Mexico
The process has been proven at commercial scale since 2022. In 2025, independent trials by Ohio State University showed that our fertilizer matched conventional UAN 28% in grain yield. Project Drake in Ohio will be Ductor’s first US facility turning poultry manure into organic liquid fertilizer, renewable natural gas and a solid soil improver.

Patented Process
Ductor’s patented process is a significant advancement in biogas technology. High concentrations of nitrogen in organic materials, e.g., such as poultry manure or fish waste, have been a challenge to biogas production in the past, as they are inhibitory.
Traditional methods of removing nitrogen from feedstock have several disadvantages, such as a reduced biogas yield, the need for large amounts of fresh water, costly supplemental feedstock, the loss of valuable nutrients and operational instability.
Ductor’s proprietary process reforms nitrogen recovery with a biological approach, which optimizes the operational, economic and ecological performance of biogas production.
Versatile Product
Biogas is a multifunctional product that can be turned into biofuels for transportation, pipeline grade biomethane, or used to produce electricity or heat.
Biomethane is identical to its fossil fuel counterpart, which allows for seamless integration or replacement in existing operations and distribution infrastructure.
Compared to other renewable energy systems, such as solar or wind, biogas is a stable, continuous process, yielding constant supply of dispatchable energy, independent from weather and season.
