How Anaerobic Digestion Works

Summary

Anaerobic digestion is a natural process where organic waste is broken down by microbes, similar to digestion in the human stomach. Organic waste from various industries, such as protein processing and food production, is processed in enclosed digester tanks, where microbes create biogas, renewable energy for local homes and businesses. The process also recycles water and turns solids into a beneficial soil amendment called digestate. This sustainable method reduces waste and contributes to a circular economy, making it an efficient alternative to incineration or landfill. For more information, visit www.bioenergydevco.com.

Takeaways

• 😀 Anaerobic digestion is a natural process where organic materials are broken down by microbes, producing solid, liquid, and gas byproducts.
• 😀 Waste from protein processing plants, food companies, fats, oils, and greases are delivered to enclosed digesters instead of being incinerated or sent to landfills.
• 😀 The waste materials are inspected and mixed with recycled water before being pumped into pre-tanks.
• 😀 The pre-tanks send the materials into large digester tanks, where millions of naturally occurring microbes break down the organics.
• 😀 As the microbes digest the materials, they produce biogas, which rises to the top of the digester tanks.
• 😀 The biogas is filtered and becomes a renewable energy source for local homes and businesses.
• 😀 Most of the water used in the process is recycled back into the system, with excess water being filtered and released to meet local discharge standards.
• 😀 The solids in the digester tanks are dewatered and turned into digestate, a healthy soil amendment.
• 😀 Digestate serves as a perfect medium to support the cycling of the process, contributing to sustainability.
• 😀 The process of anaerobic digestion is referred to as Nature's recycling engine, offering an environmentally friendly waste management solution.

Q & A

What is anaerobic digestion?

Anaerobic digestion is a natural process where organic materials are broken down by microbes in the absence of oxygen, producing solids, liquids, and gases.

What types of waste are used in the anaerobic digestion process?

Waste from protein processing plants, food production companies, and fats, oils, and greases are used in the anaerobic digestion process.

How is the waste processed before entering the digester tanks?

The waste is inspected, mixed with recycled water, and then pumped into pre-tanks before being sent to the large digester tanks.

What role do microbes play in anaerobic digestion?

Microbes in the digester tanks break down organic materials, which leads to the production of biogas.

What happens to the biogas produced during anaerobic digestion?

The biogas rises to the top of the digester tanks, is filtered, and then used as a renewable energy source for local homes and businesses.

What happens to the water used in the anaerobic digestion process?

Most of the water is recycled back into the system, while any excess water is filtered to meet local discharge standards and then released.

What is digestate, and what is its purpose?

Digestate is a solid byproduct of anaerobic digestion that is dewatered and turned into a healthy soil amendment, which can be used to improve soil quality.

How does anaerobic digestion contribute to sustainability?

Anaerobic digestion helps reduce waste sent to landfills and incinerators, provides renewable energy, and produces a valuable soil amendment, contributing to a circular economy.

Can anaerobic digestion be applied to different types of organic waste?

Yes, anaerobic digestion can process various organic materials, including food waste, agricultural residues, and industrial byproducts.
