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 […]
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 […]
Fixed Dome Biogas Plant Design & Installation Guide
Fixed dome biogas plants offer a sustainable energy solution with lifespans over 20 years, converting waste into fuel. Their underground design provides natural pressure and temperature stability, saving surface space. Proper site selection and construction enhance efficiency, making them ideal for developing regions seeking energy independence…
Biogas Yield Analysis & Best Practices: Maximizing Output from Food Waste
Food waste can generate up to 0.65 m³ of biogas per kg of dry matter. Optimising conditions like temperature, pH, and co-digestion with other substrates can significantly boost biogas yields, transforming organic waste into a sustainable energy source while reducing environmental impact…
What Does it Mean if a Process is Anaerobic? Definition & Explanation
An anaerobic process is any biological or chemical process that occurs without oxygen. Key examples include anaerobic respiration, where cells generate energy sans oxygen, and anaerobic digestion, where organisms break down waste to produce biogas, illustrating the essentiality of such processes in oxygen-limited environments…
