What is Anaerobic Digestion?
So, what is Anaerobic Digestion? Anaerobic Digestion involves using the natural process wherein organic matter is broken down by germs, in the absence of oxygen, inside a sealed tank. For both processes, a digester tank is made use of: a gas-tight, sealed vessel with draw-off points, in which plant and animal material (biomass) is naturally […]
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 […]
How Chemical Mixing Stations Help Farmers Cut Down on Costs
Nowadays, farming has become more eco-conscious. More and more farmers are now using biogas slurry and other more nature-friendly options to fertilise their crops and gardens. However, even if farmers will eventually be able to reduce their need for chemical fertilisers, it’s still more practical nowadays to use a mix of chemical and natural fertilisers […]
The Role of Bulk Buying in Reducing Food and Packaging Waste
How to Cut Down on Food and Packaging Waste by Buying in Bulk Food waste and excessive packaging contribute to environmental harm and economic inefficiencies. Bulk buying has emerged as a powerful strategy as consumers and businesses look for ways to minimize their impact. Individuals and organizations can reduce waste, save money, and make more […]
Centrifugal Pumps Vs Positive Displacement Pumps: A Comparison Of 2 Pump Types
Understand when to use Centrifugal Pumps Vs Positive Displacement Pumps and you have the makings of a useful engineering skill Choosing the right pump can feel like solving a tricky puzzle, especially when designing anaerobic digestion and biogas plants. That’s because feeding a digester with organic pulp requires pumping a viscous liquid, and similarly for […]
Dry Anaerobic Digestion: Renewable Energy Extraction from Residual Municipal Waste
Dry anaerobic digestion is a new way to manage waste with the benefit of renewable energy extraction from residual municipal waste and other wastes with a high organic content. It uses tiny organisms in the digestate that is recirculated as an inoculum into fresh waste batches to turn waste into biogas, a clean energy source. […]
How to Store Biogas at Home: Safety Methods & Products
Storing biogas at home offers an eco-friendly energy solution, but it requires careful handling and robust, gas-tight storage. Ensure safety with low-pressure systems, regular maintenance, and leak testing. DIY options can be practical and cost-effective if done correctly, making biogas storage a viable sustainable choice…
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”. […]
Anaerobic Digestion Tanks
Anaerobic digestion tanks (often known as biogas tanks, or digester tanks) are large, usually circular in plan, and very distinctively topped with their flexible gas storage plastic membrane covers, that are often cone shaped and supported at the centre with a single pole. These innovative vessels not only treat waste but also generate biogas—a valuable […]
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 […]
