Your Source for Anaerobic Digesters
What Are Anaerobic Digesters?
Anaerobic digesters, also known as compost methane generators, are large vessels that use an oxygen-free environment to break down organic material into biogas. The process is powered by bacteria, which feed on the organic matter in the vessel, producing methane, carbon dioxide, and other gases as a byproduct. This gas can then be used to generate electricity or heat buildings. The liquid residue created from the digestion process can also be used as fertilizer for crops.
The Purpose of Anaerobic Digesters
Anaerobic digesters reduce environmental footprints by eliminating waste materials and converting them into energy. By breaking down organic waste in an oxygen-free environment, an application or operation can avoid the emissions of methane and other greenhouse gases that would normally occur with traditional waste disposal methods. Using anaerobic digesters can also reduce the amount of energy needed to power wastewater treatment plants, saving money in the long run.
Who Would Need to Use Anaerobic Digesters?
Industries such as wastewater treatment plants are prime candidates for using anaerobic digesters because they produce large amounts of organic waste on a regular basis. Farms that generate manure also benefit from using anaerobic digesters because they can convert animal waste into energy while simultaneously avoiding large emissions of methane and other pollutants into the atmosphere. Other industries that could use anaerobic digesters include food processing facilities, breweries, and distilleries that regularly produce large amounts of organic material.
Is Digestion Endothermic or Exothermic?
Digestion is exothermic in an anaerobic reactor due to the conversion of complex molecules like proteins, carbohydrates, and lipids into simpler molecules like carbon dioxide and hydrogen via bacterial action. By breaking down these complex molecules into simpler ones, heat is released in metabolic heat production, leading to a higher temperature than its surroundings, making digestion exothermic inside an aerobically operated reactor. Operators of these reactors need to monitor temperatures closely since high temperatures can harm bacteria present during digestion.

Our Selection of Anaerobic Digesters at Pioneer
Fixed Dome Anaerobic Digester
The fixed dome anaerobic digester is a simple and cost-effective solution for small-scale organic waste management. The digester consists of a fixed dome made of reinforced concrete and a mixing tank where the organic waste is introduced. The biogas produced during anaerobic digestion is collected in the dome and used for heating, electricity generation, or other applications. The remaining digested slurry can be used as a high-quality organic fertilizer.
Floating Dome Anaerobic Digester
The floating dome anaerobic digester is similar to the fixed dome digester but with a floating dome that rises and falls as biogas is produced and consumed. The floating dome provides additional storage for biogas and can accommodate larger volumes of organic waste. This product suits small to medium-sized farms, food processing, and industrial facilities.
Complete Mix Anaerobic Digester
The complete mix anaerobic digester is a thoroughly mixed reactor that ensures the uniform distribution of organic waste and microorganisms throughout the digester. The digester is equipped with an agitator or mixer that continuously stirs the contents of the reactor. This type of digester is suitable for large-scale organic waste management, such as municipal wastewater treatment plants, industrial waste management, and agricultural operations.
Plug Flow Anaerobic Digester
The plug flow anaerobic digester is a long, narrow reactor that operates semi-continuously. The organic waste is introduced at one end of the reactor and moves through the digester at a controlled rate. The microorganisms digest the organic waste as it moves through the reactor, producing biogas and fertilizer. The plug-flow anaerobic digester suits large-scale waste management, such as municipal wastewater treatment, agricultural operations, and industrial waste management.
Upflow Anaerobic Sludge Blanket (UASB) Reactor
The Upflow Anaerobic Sludge Blanket (UASB) reactor is a high-rate anaerobic digester that can treat high-strength wastewater with a high concentration of organic matter. The UASB reactor uses a specialized sludge bed to retain the microorganisms responsible for anaerobic digestion. The UASB reactor is suitable for industrial wastewater treatment, such as pulp and paper mills, food processing facilities, and chemical manufacturing plants.
The Benefits of Pioneer Air System’s Anaerobic Digesters
- Anaerobic digesters reduce the amount of organic waste sent to landfills, which reduces greenhouse gas emissions and helps combat climate change.
- The digesters generate biogas, a renewable energy source that can power homes, businesses, or even vehicles.
- The digested material, called digestate, is a nutrient-rich fertilizer that can be used to improve soil health and crop yields.
- The anaerobic digestion process also reduces odors, making it a more pleasant option for managing organic waste than traditional methods like composting or landfilling.
- Pioneer Air System’s anaerobic digesters are customizable and can be tailored to fit each facility or operation’s specific needs and challenges, making them a flexible waste management solution.
- The digesters are designed to focus on reliability and ease of operation, minimizing downtime and maintenance costs.
