What is an RNG digester?

An RNG digester is a system that breaks down organic waste (such as manure, food waste, or sludge) in an oxygen-free environment, producing biogas rich in methane, which can be converted into renewable natural gas (RNG) for energy use.

Why is digester management important?

Proper digester management ensures efficient gas production, prevents leaks, optimizes waste processing, and maintains compliance with environmental regulations.

What materials are used for digester liners and covers?

Plastic Fusion provides HDPE, RPP, and XR-5 liners and covers that offer:

• High chemical resistance for wastewater and organic waste
• Superior durability for long-term RNG production
• UV and gas resistance for optimal containment

How does RNG digester gas collection work?

Methane gas is captured beneath the digester cover, then processed, cleaned, and injected into the natural gas pipeline or used for on-site power generation.

What Is Digester Gas?

Digester gas is a byproduct of anaerobic digestion, where organic waste—such as manure, food scraps, or wastewater sludge—breaks down in the absence of oxygen. This process produces biogas, primarily composed of methane (CH₄) and carbon dioxide (CO₂), which can be used as a renewable energy source.

What Is Gas Treating for Biogas?

Gas treating for biogas involves removing impurities like hydrogen sulfide (H₂S), moisture, and siloxanes to improve biogas quality. Cleaned biogas can be used for electricity generation, heating, or upgrading to renewable natural gas (RNG) for injection into pipelines.

How Is Digester Gas Cleaned?

Digester gas cleaning removes contaminants like H₂S, CO₂, moisture, and particulates to meet energy standards. This is done using technologies such as activated carbon filtration, chemical scrubbing, and membrane separation to produce high-purity methane.

What Is Wastewater Digester Gas?

Wastewater digester gas is the biogas generated from the breakdown of sewage sludge in wastewater treatment plants. It can be captured and used for on-site power generation or converted into renewable natural gas (RNG).

What Are Industrial Digester Services?

Industrial digester services include the design, maintenance, repair, and optimization of anaerobic digesters used in wastewater treatment, food processing, and agricultural applications. These services ensure efficient biogas production and system longevity.

How Is Gas Cleaned for Anaerobic Digestion?

Gas cleaning for anaerobic digestion removes harmful contaminants like sulfur compounds, moisture, and volatile organic compounds (VOCs) to improve biogas quality. This process is essential for protecting equipment and maximizing energy recovery.

What Is a Plastic Biogas Digester?

A plastic biogas digester is a low-cost, flexible system used for small-scale biogas production. Made from durable plastic membranes, these digesters efficiently convert organic waste into usable methane gas for cooking or heating.

What Is RNG Digester Management?

RNG digester management refers to monitoring and optimizing anaerobic digestion systems to maximize renewable natural gas (RNG) output. This includes feedstock management, gas cleaning, system maintenance, and regulatory compliance.

How Is Industrial Digester Repair Performed?

Industrial digester repair involves identifying leaks, replacing damaged components, and restoring gas flow efficiency in large-scale digestion systems. Repairs ensure continued biogas production and regulatory compliance.

Can Plastic Fusion install and maintain digester systems?

Yes! We specialize in full-service installation, maintenance, and repair for RNG digesters, gas collection systems, and containment solutions.

How can I improve my RNG digester’s efficiency?

✔ Use high-quality geomembrane covers to prevent gas loss
✔ Regularly maintain gas collection systems
✔ Optimize organic waste feedstocks
✔ Ensure proper liquid containment & leachate management
