What Is Anaerobic Digestion? A Practical Guide to the Process
Anaerobic digestion (AD) is a controlled biological process in which communities of microorganisms break down biodegradable organic material in the absence of oxygen. The process takes place in a sealed vessel called an anaerobic digester and produces two main outputs: biogas, an energy-rich gas containing methane, and digestate, the remaining liquid and solid material containing […]
Two Stage Anaerobic Digestion
Anaerobic digestion (AD) has emerged as a pivotal technology in the renewable energy sector, particularly for the sustainable production of biogas. Among the various configurations of AD systems, the two-stage anaerobic digestion process stands out for its ability to enhance both process stability and biogas yield. This comprehensive guide delves into the intricacies of two-stage […]
What is Biogas?
Just what is biogas? Biogas is a renewable energy source generated through the anaerobic digestion of organic materials such as agricultural waste, manure, municipal sewage sludge, plant material, and food waste. This natural process breaks down organic matter in the absence of oxygen, producing a gaseous mixture primarily composed of methane (CH₄) and carbon dioxide […]
Boost Sustainability with Farm Digesters – Energy, Materials Circularity and Efficient Waste Management
Farm Digesters in 2024: A Guide to Better Agricultural Sustainability and Waste Management Did you know that farm digesters can reduce greenhouse gas emissions by up to 85% compared to traditional manure management? In an era where sustainable agriculture isn’t just an option but a necessity, farm digesters are emerging as a game-changing solution for […]
What is the Difference Between Biogas and Landfill Gas?
We saw that a question being asked on the forums is, “What is the difference between biogas and landfill gas?”, so we thought that we would write this article to explain. Read on to find out the differences of biogas versus landfill gas, and you will appreciate that people tend to call landfill gas “biogas”. […]
Mesophilic Anaerobic Digestion and the Thermophilic Temperature Range
If you said that mesophilic anaerobic digestion is “cool”, you’d be right compared with the other common temperature range used for AD plants, but probably in more ways than one! The term mesophilic when referring to a biodigestor has been adopted by biogas plant designers to distinguish between the two best temperature ranges for operating […]
Anaerobic Digestion of Manure
Anaerobic Digestion of Manure: A Comprehensive Guide to Sustainable Energy Production Anaerobic digestion is a biological process that transforms organic materials, such as livestock manure, into renewable energy. This article explores the significance of manure management in agriculture and the role of anaerobic digestion in promoting sustainable farming. The anaerobic digestion of manure is the most common type of on farm anaerobic […]
How Is Biogas Produced? A Simple Explanation
Biogas is produced when microorganisms break down biodegradable organic matter in the absence of oxygen, a process known as anaerobic digestion. Organic materials such as food waste, animal manure, sewage sludge and agricultural residues are placed in a sealed digester, where a community of microorganisms progressively converts part of the organic matter into a gas […]
Anaerobic Digestion Process: Stages, Systems and Controls
The anaerobic digestion process is a controlled sequence of microbial reactions that converts biodegradable material into raw biogas and digestate without oxygen. In a working plant, success depends on much more than putting organic waste into a sealed tank. Feedstock preparation, loading rate, temperature, pH, mixing, retention time, gas handling and digestate management must all […]
Slurry Value: The Natural Fertiliser Resource for Sustainable Farming
Hey! Slurry value? The very association of the two words “slurry” and “value” will, we are sure, raise many eyebrows in disbelief! So, is this some sort of a deep fake article? We assure you it is not! Slurry, a semi-liquid manure produced by livestock, holds significant value for farms as a natural fertilizer. Understanding […]
Anaerobic Digestion and Biogas Off-Grid for Remote Communities
Biogas off-grid is an ideal energy for remote communities and homes far from the nearest power lines. Living off-grid can be rewarding, but it also comes with its own set of challenges. Many remote communities struggle with unreliable energy sources and high costs of fuel. 1 Without easy access to electricity or clean cooking gas, daily life becomes harder. 2 Biogas […]
California Climate Action Plan: How Republic Services Enhances Biogas Production with Landia’s Chopper Pumps
As the State of California intensifies its efforts to mitigate the impacts of climate change, key legislative and policy measures, including the ambitious California Climate Action Plan, aim to reduce the state’s environmental footprint. One significant challenge is the management of the 11 million tons of organic waste produced annually, a critical issue addressed through […]
