Digestate and post- biogas phase

Biological management of process continuity

Stabilizing digestate to maximize energy, environmental, and agronomic value

Anaerobic digestion is a crucial phase in livestock manure management, enabling the energetic valorization of carbon through biogas production.


After the biodigester, the biological process does not stop.
Digestate is a highly biologically reactive matrix that requires careful management to fully express its agronomic and environmental value.


The post-biogas stage is where process quality truly makes the difference.

Digestate as an active biological system

Nitrogen, carbon, and process continuity
During anaerobic digestion:

  • carbon is partially valorized for energy

  • nitrogen becomes more available

In the post-biogas stage, the biological management of digestate is key to:

  • improving nitrogen efficiency

  • reducing losses through volatilization

  • promoting greater manure stability

 

Post-digestion biological management

SOP acts in the post-biogas stage, promoting:
  • microbial balance
  • greater digestate stability
  • integration between storage and agronomic use
This approach helps to:
  • make digestate more homogeneous
  • improve tank management
  • support more efficient field application
SOP LAGOON operates precisely at this stage, serving as a biological lever in the process.

Digestate, slurry, and an integrated approach

Digestate management is part of a broader vision that includes:

  • biological management of manure

  • reduction of environmental pressures

  • agronomic valorization of livestock effluents

Environmental and institutional alignment

Biological management of digestate in the post-biogas stage is aligned with:

  • circular economy strategies

  • emission reduction policies

  • ESG criteria in agri-food supply chains

  • environmental sustainability goals

Science and process-based approach

The SOP approach to digestate management is based on:

  • understanding biological cycles

  • observing real-world processes

  • field trials under operational conditions

Available evidence supports a progressive and integrated management approach, capable of improving digestate quality and the overall sustainability of the system.

Frequent questions about Manure, Digestate, Emissions

What does biological manure management mean according to SOP?
For SOP, biological manure management means considering slurry and digestate as active biological systems. By managing microbiological dynamics, SOP works to improve stability, agronomic quality and emission control, transforming manure into a resource that is functional to the farm system.

How does SOP contribute to reducing ammonia emissions in livestock farming?
SOP addresses ammonia reduction by improving the efficiency of the nitrogen cycle. It acts on the biological conditions of the manure system and the livestock environment, promoting more stable processes that reduce losses and improve nutrient utilization.

Does biogas completely solve the emission problem?
According to SOP, anaerobic digestion represents an important phase of energy valorization. After the biodigester, biological management of digestate becomes crucial to complete the process, reduce residual emissions and improve integration with crop production.

How does SOP contirbute to emission reduction targets?
SOP acts on the biological processes that influence ammonia, methane and other gas emissions. Improving system efficiency makes it possible to reduce losses and increase the functional use of resources. Learn more: Methane from manure
How does SOP contribute to reducing manure odors?
SOP addresses manure odor issues by acting on the biological processes that regulate fermentations within the manure system. When manure is biologically unbalanced, undesired fermentations increase, generating odorous compounds. Through biological manure management, SOP works to stabilize the system, reducing odor production while simultaneously improving the agronomic quality of the manure..
