globe Anaerobic Digestion

The basic steps of anaerobic digestion are as follows:

  1. Decomposition of organic matter to
    usable-sized molecules
  2. Conversion of decomposed matter to organic acids
  3. Conversion of the acids to methane gas

    

Anaerobic DigesterNEAtech has extensive anaerobic design experience. Anaerobic digestion is a microbial bioconversion process which recycles organic carbon in biomass into "biogas", a medium BTU fuel gas comprised primarily of methane and carbon dioxide. Biogas is produced from organic wastes such as livestock manure, food processing waste, etc.

Each plant must be custom designed for the local feedstock supply and energy needs. Our knowledge and experience will enable your anaerobic digester plant to reach optimal performance and maximize profits.

We offer an independent third party evaluation of your anaerobic digestion project.

Benefits of Anaerobic Digestion:

Methane provides a source of renewable energy that is carbon neutral and can be used for steam and electricity production, hot water, and space heating. Methane can also be sold to natural gas companies, or compressed and used as a transportation fuel.

Complementary benefits include odor and pathogen reduction, and the potential to generate clean water. Co-products such as fertilizer and soil amendments are also produced.

The most common issues associated with an Anaerobic Digester Project are:

    1. Capital Cost
    2. Plant Management
    3. Feedstock Supply
    4. Wastewater Management
    5. Offtake Agreements
    6. Utility Agreements
    7. Documentation of carbon offset credits

Anaerobic Digestion Feedstocks:

  • Residential and commercial food waste
  • Manure – dairy, swine, and poultry
  • The Organic Fraction of MSW
  • Fruit & vegetable processing wastes
  • Meat packing processing by products
  • Waste beverages

  

Primary Uses of Biogas:

  • Electricity Generation - Biogas is typically combusted in an engine to produce electricity
  • Steam Production - Biogas can be combusted in a boiler to produce steam for process heating
  • Natural Gas Production - Biogas can be upgraded to natural gas quality and injected into pipelines
