Anaerobic Digestate Fertilizer for Plant Nutrition in Agriculture
Anaerobic digestate fertilizer can be an important source of the essential elements of plant nutrition in agriculture. To put it simply: The sustainable renewable fertilizer made from the leftovers of the “decomposition process that doesn’t use oxygen” can be a key source of the vital nutrients plants need to grow in farming. For the agricultural […]
How to Improve Soil Health: The Planet Saving Role of Compost and Digestates
How to Improve Soil Health is a pressing concern. It was the subject of evidence Dr Jane Gilbert from Carbon Clarity gave oral evidence on behalf of CIWM to the Environment, Food and Rural Affairs Committee at the House of Commons recently. Her presentation was provided with an emphasis on the value of compost and […]
Digestate from Anaerobic Digestion: A Valuable Nutrient-rich Liquid for Sustainable Agriculture
Using digestate from Anaerobic Digestion provides a valuable plant fertiliser. In fact, unlocking the potential of digestate is vital for the sustainability of the agriculture sector. There is nothing else quite as good when you take a holistic view of its many benefits. Digestate is a valuable nutrient-rich liquid produced from the process of anaerobic […]
Microplastic Contamination in Compost – Composted Green Waste vs Digestate
Microplastic contamination in compost is a problem now, and in geological timescales, all plastic in soils will be washed into the oceans, leading to yet more microplastics in the oceans. But which source of compost is worse for containing microplastics? Composted green waste or the digestate from anaerobic digestion? In this article, we compare both. […]
Drying Digestate from Biogas Plants – Fluidised Bed Fertiliser Advances
Drying digestate from biogas plants has major benefits. In the advanced TEMA Process™ a fluidised bed dryer dries the residual waste after digestion (the solid and fibrous (thick) portion of the digestate slurry). The mixed stream of the thick fraction and the concentrated thin fraction is dewatered to 70-75% Moisture Content. This is followed by […]
Screw Separation of Biogas Digestate is Now a Farm Favourite
Screw Separation of Biogas Digestate is a commonly used method of dewatering digestate. It uses mechanical pressure to separate organic fibres and larger particles from the liquid. The resulting liquid which flows out through the screen is usually suitable for use as a natural bio-fertiliser, for use on the farm. The exception to this can […]
How to Use Digestate from Anaerobic Digestion Plants in Agriculture
It’s not plain sailing to use digestate in agriculture, so we thought that we would explain how one farm uses their digestate in their agricultural business in the UK. Using Digestate from Anaerobic Digestion Plants in Agriculture Anaerobic digestion is a controlled biological process using biodegradable materials such as food waste and animal manures, to […]
Could Börger FlowSep Transform Food Waste Anaerobic Digestion Pretreatment?
The Hidden Cost of Grit and Inerts in AD Plants Removing sand, grit, glass, and other inert material has long been recognised as important in anaerobic digestion plant operation, but it is often still underestimated in practice. In many food waste anaerobic digestion facilities, especially, these unwanted materials enter with the incoming feedstock and then gradually accumulate inside the digester, pipework, and associated […]
Biogas Production from Sewage Sludge Methods & Techniques
Biogas production from sewage sludge uses anaerobic digestion to break down organic matter in wastewater solids (biosolids), creating a renewable, methane-rich gas. This process, accelerated by technologies like thermal hydrolysis and advanced anaerobic digestion, typically produces 350 m3 of biogas per ton of sludge, which can be used for electricity, heating, or vehicle fuel. Ideas […]
Food Waste To Animal Feed Vs Food Waste To Anaerobic Digestion: Which Is Best?
Using food waste, that’s still edible, to make animal feed is generally preferred for nutrient recovery and lower environmental impact, keeping materials in the food chain longer. Conversely, anaerobic digestion (AD) is superior for managing heavily contaminated or non-edible waste, converting it into renewable energy (biogas) and fertiliser. Both methods are far superior to landfills. […]
Best Liquid Digester Additives for Effective Biogas Yield Optimisation
Liquid digester additives enhance biogas yield by enriching anaerobic digestion with essential trace elements and enzymes. Products like MethaneMaxx™ boost methane production by addressing nutrient imbalances. Customization is crucial; the right additive depends on feedstock composition, digester type, and temperature to maximize efficiency and output…
Best Insurance for Anaerobic Digestion Plant, Coverage & Options
Anaerobic digestion plant insurance provides coverage for biogas facilities, protecting against risks like equipment breakdown and revenue loss. Specialist insurers offer packages covering construction, operation, and environmental liability. The type of feedstock processed influences premiums and coverage options, making tailored insurance essential for AD operators…
Business Interruption Insurance For Anaerobic Digestion Plants: What You Need To Know
Business interruption (BI) insurance for anaerobic digestion (AD) plants protects against lost revenue and fixed costs resulting from operational downtime caused by incidents like fire, machinery breakdown, or grid failure. It is crucial for covering revenue gaps during repairs, with indemnity periods typically structured around income loss. Protecting your consistent revenue stream is the primary […]
Scotland’s Green Gas Moment: How the May Elections Could Transform Farming Energy Forever
Scotland is developing its green gas sector, aiming for net-zero by 2045 through anaerobic digestion (AD) for biogas and pioneering green hydrogen projects. Now is the moment to go faster and simultaneously help their struggling small farms. Every five years, Scotland gets a new government. And every new government needs a plan. The six-week window […]
Scaling Food-Waste-to-Energy: Why Biochar Is The Key To Higher Gas Yields
Many waste management professionals face a major challenge. Food waste piles up fast, fills landfill sites, and turns into harmful greenhouse gases like methane and carbon dioxide. Traditional ways of turning food rubbish into energy struggle with low gas yields, unstable systems, and rising costs. Biochar offers a real breakthrough for the “Food Waste to […]
