Anaerobic Digestion
Anaerobic Digestion in Scotland Key to Sustainable Scottish Energy Strategy
Anaerobic Digestion in Scotland is seen by policymakers as being the key to a sustainable Scottish Energy Strategy. 100% renewable energy from the digestion of biodegradable waste helps tackle climate change, instead of contributing to climate change through landfilling and incineration. This energy output helps cut fossil fuel use and reduce greenhouse gas emissions. There are […]
Get a Higher Price for Biogas from Waste with Renewable Gas Guarantees of Origin (RGGOs)
Biogas plant owners can now get a higher price for biogas or biomethane made from waste organics (biowaste) than for biogas or biomethane which uses food crops in their feedstock. Argus, one of the world’s top energy and commodity intelligence companies, has just released prices for biomethane guarantees of origin. Biomethane can be used as […]
High Rate Anaerobic Digestion Plant Treats Wastewater Effluent Streams
By definition, a High Rate Anaerobic Digestion Plant can effectively handle high-strength wastewater effluent streams, such as sewage sludge. To be high rate it needs to be able to provide the necessary reactions at a higher rate than traditional biogas process plant which need a 30 day retention period or longer. Back in 2017, we […]
Biogas in South Korea
The prospect for Biogas in South Korea is looking up! Since President Moon Jae-in took office, the prospects for anaerobic digestion in South Korea have increased. The government has been making strenuous efforts to attain autonomy in the electricity and heat sectors, as well as to considerably expand the percentage of renewable energies. Increasing the […]
Egg Shaped Anaerobic Digesters – Strange Looking Tanks Explained
Egg Shaped Anaerobic Digesters; Enormous eggs! Whatever next! Have you ever wondered what those huge “strangely other-world like” not quite “spherical” tanks are that you sometimes see? They are anaerobic digestion process digesters, and very useful they are too! They make sewage sludge much more wholesome and in particular, they reduce sludge odour, but best […]
Anaerobic Digestion in Wastewater Treatment – UASBs EGSBs and Staging
The Role of Anaerobic Digestion in Wastewater Management Typically, anaerobic digestion (AD) has been used for municipal wastewater sludge treatment, and in the industrial wastewater sector for COD/ BOD reduction as in the Upflow Anaerobic Sludge Bed (UASB). Only very rarely has it been used to treat industrial effluent the vast majority of which continues […]
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 Diary 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 […]
Anaerobic Digestion of Manure & Biogas Plant Productivity Doubled In Tests
Here we discuss the Anaerobic Digestion of Manure: The first section is a general informational article, followed by our original article where we explain their 2017 breakthrough in the throughput of manure-fed AD Plants described by the Ductor biogas company using chicken manure. Anaerobic digestion (AD) of dairy manure provides several environmental and economic benefits, […]
Anaerobic Digestion UK Capacity Enough to Power 1 Million Homes – Future Doubts Continue
It was 2017 when we announced that UK Anaerobic Digestion capacity had grown rapidly to be enough to power 1 million homes. But, we doubted that growth of the industry at the same rate would continue in future years. To be able to power 1 million homes is big! In fact, it’s a very significant […]
Anaerobic Digestion in Australia
The development of anaerobic digestion in Australia, after a slow start, does now seem to be picking up momentum. The process is well-known for its renewable energy production. It is less known that the biogas sector provides an alternate waste treatment method while also helping to boost local economies, but Australians are waking up to […]
