Digester cleaning prevents costly failures by removing sludge and grit. Professional services boost biogas production and extend equipment life. Advanced depackaging reduces cleanout needs. Proper separation extends maintenance intervals, saving costs from neglected systems and avoiding penalties, making them a vital part of digester care…
The Role of Anaerobic Digestion in Wastewater Treatment – UASBs EGSBs CSTRs and Staging
Anaerobic digestion transforms wastewater into resources through biogas production, enhancing energy efficiency and reducing emissions. With systems like UASBs and EGSBs, it excels in industrial and low-strength waste treatment. Multi-phase staging boosts efficiency, driving sustainable wastewater solutions forward…
Biomethane Gas to Grid Injection Solutions & Green Gas Supply
Biomethane grid injection upgrades biogas into a clean, renewable gas, reducing emissions by up to 85%. With growth projected to meet net-zero targets, this method leverages existing infrastructure for maximum efficiency. Key components ensure safe integration, making biomethane a vital player in the future of green energy…
Food Waste: Packaging Contamination Threatens Processing Feed for Anaerobic Digestion
Packaging contamination in the food waste recycling industry occurs when inadequate separation of the packaging from food waste occurs, and when physical contaminants such as microplastics and nanolastics are introduced into anaerobic digesters from the packaging itself. You toss out expired yoghurt, a mouldy sandwich, and soggy lettuce. Each one sits in a wrapper or […]
Biomethane in Northern Ireland: How the Region Could Lead the UK’s Green Gas Revolution
Biomethane is being introduced into Northern Ireland’s gas network to help decarbonize its energy supply, with the first injection into the grid occurring in November 2023. The potential exists for the province to develop a lead, but is the government doing enough? Produced from agricultural and food waste through anaerobic digestion, biomethane can be used […]
How Anaerobic Digestion Reduces Landfill Reliance — and Why It’s Better Than Incineration for a Circular Future
Anaerobic digestion (AD) is remarkable for its ability to reduce landfill reliance by diverting organic waste from landfills, where it would otherwise release methane, and transforming it into valuable products like renewable biogas and fertiliser. Read on and find out how it gets even better, because this process significantly decreases the volume of waste sent […]
5 Advantages of Digestate Separation Using Borger Bioselect Digestate Separator Technology
In this article, we identify the five top Advantages of Digestate Separation using the Borger Bioselect digestate separation technology, available from manufacturer Börger GmbH Borken-Weseke, Germany. Scroll down to see the list of the top advantages! Liquid/ Solid Separators (also known as screw separators) are a widely used separation technique for digestate separation in biogas plants […]
Biogas Inhibition Tests for Inhibitors Such as High Ammonia in AD Substrates
Quick Biogas Inhibition Tests to identify inhibitors in Biogas Substrates are badly needed by the commercial biogas plant industry. Traditional methods, such as the Dairy Farmer’s “Aerobic Plate Count” inhibitor test, are not directly applicable to anaerobic biogas conditions, so a New Biogas Substrate Inhibition Test Method has been badly needed. Read on to find […]
