Capturing high yields through process control
Anaerobic digestion is a natural process that uses microorganisms to break down organic materials like animal and plant material inside a closed tank. This zero-oxygen process yields methane, CO₂, clean water and many other valuable products.
Natural, clean and efficient technology
Anaerobic digesters have been used for decades in the US and throughout the world as a wastewater treatment technology. We leverage this process to create a biorefinery where we carefully control the inputs to reliably produce the desired outputs. The value of our biorefinery process is that it recovers virtually everything inside the waste, creating high value products with no new waste.
1. Organic Material from food producers is trucked into the plant and introduced into the digester.
2. Microbes in the zero-oxygen environment break the material down at a controlled temperature.
3. This yields biogas that is comprised of methane and CO2 along with a slurry-like material called digestate.
4. We collect the biogas and separate the methane and CO2.
• We recover methane and send it directly into the local natural gas pipeline.
• We capture the CO₂ for sequestration or use in the food & beverage industry
• We remove nutrients from the digestate, like nitrogen and phosphorus for use in fertilizers.
• We can recycle warm water generated by the process.
