A Case Study: Anaerobic Digestion of Dairy Manure and Food Processing Waste with Renewable Energy, Composting and Manure Injection (FS-2023-0694)

Anaerobic digestion of manure with food processing waste resulted in renewable electricity production for 190 house and reduced 81% of greenhouse gas emissions from manure management. The solids were separated from the manure for composting, with the digester effluent injected into the soil as a fertilizer. This FactSheet is part of the ‘Animal Waste Technology’ series.

Composting (FS-2023-0687)

Composting is an aerobic biological process that transforms organic materials, such as manure, food waste, and yard waste, into a nutrient-rich soil conditioner called “compost.” This Factsheet is part of the “Animal Waste Technology” series. Authors: Amro Hassanein, Stephanie Lansing, and Danielle Delp; Title: Composting (FS-2023-0687).

Anaerobic Digestion (EBR-2023-0686)

Anerobic digestion uses natural microorganisms to produce renewable energy in the form of electricity, heating, or vehicle fuel. Anaerobic digestion occurs inside a sealed reactor called a digester and reduces odors and greenhouse gas emissions. This Fact Sheet is part of the ‘Animal Waste Technology’ series. Authors: Amro Hassanein, Stephanie Lansing, and Danielle Delp; Title: Anaerobic Digestion (EBR-2023-0686).

Anaerobic Digestion: Basic Processes for Biogas (FS-994)

Anaerobic digestion is a process where anaerobic bacteria break down organic material to produce biogas. This process occurs naturally in various environments and can be used in anaerobic digesters to treat and dispose of waste, generate biogas, and destroy pathogens. The biogas produced consists mainly of methane and carbon dioxide, with trace levels of other gases.

Using Thermochemical Processes to Handle Agricultural Waste (FS-2023-0688)

Thermochemical processing technologies can be used to reduce the volume of low moisture waste and produce heat, syngas for renewable energy production, biochar, or bio-oil, depending on the temperature and oxygen conditions used in processing. This Factsheet is part of the “Animal Waste Technology” series.
