UK Food Waste Anaerobic Digestion Plant History of the Ludlow Digester
In the UK Food Waste Anaerobic Digestion Plant History began with the dedicated Food Waste AD Waste Technologies Demonstrator Plant, known as the Ludlow Digester. In the UK the history of dedicated food waste anaerobic digestion plants began there in 2004, when the innovative government funded plant opened. At the time, nobody was sure that […]
Aerobic Digestion and Anaerobic Digestion – A Comparison
Any comparison of Aerobic Digestion and Anaerobic Digestion should first explain that a comparison can be made either on the basis of either: microbiology ( the study of microorganisms) or respiration systems in man and mammals generally. In this article we compare (1) aerobic digestion with anaerobic digestion (2), in the context of microbiology and […]
Changes in UK Small-Scale AD Subsidies – Reductions to New Applicants
This is for those interested in UK Small-Scale AD Subsidies. Small-Scale AD Subsidies – Government Confirms New Feed-in -Tariff rates “The government also confirmed that a degression mechanism will be introduced for Anaerobic Digestion (AD), wind and hydro technologies from April 2014 in line with uptake, rather than the initial proposal of a minimum five […]
WRAP Defends Anaerobic Digestion from “Slopbuckets Farce” Food Waste Collection Slur
WRAP Defended Anaerobic Digestion of food waste as a newspaper branded its collection from householders as a “slopbuckets farce“, earlier that month! (May 2012). UK funded government organisation WRAP has defended household food waste collections. These are destined for Anaerobic Digestion facilities, while the Daily Mail belittles government efforts. It believes to collect food waste […]
Waste Autoclave Pretreatment with Anaerobic Digestion for Household Waste
Waste Autoclave pretreatment of residual household waste, and food waste, for all its undoubted advantages in increased biogas yield during subsequent anaerobic digestion of the organic fraction, has met with a difficult period. The story has not been a good one, since we originally posted our article on this subject in May, 2012. In a […]
Anaerobic Digestion in the US Shows Growth Despite Low Electricity Prices
Anaerobic Digestion in the US is expanding despite no subsidies, in most cases. Many opinion-formers suggest that Anaerobic Digestion technology needs strong subsidies to have a chance of being developed to meet its potential. However, US AD site “Biocycle”, has posted an article which suggests the contrary. It says that’s not the case in the […]
Food Waste Recycling Machine Raises Purity of Pretreated Biogas Substrate to New Level
Gemidan Ecogi’s anaerobic digestion substrate pre-treatment system is effectively a food waste recycling machine for large commercial biogas plants which produces a high-quality pulp-based substrate for digestion/ energy production in AD/ biogas plants. The Gemidan ECOGI system (food waste recycling machine) has a reputation for enhancing the recovery of renewable energy during the anaerobic digestion […]
Low Cost Faecal Sludge Management and the Role of Anaerobic Digestion Co-Disposal
Before discussing low cost faecal sludge management and the role of Anaerobic Digestion Co-Disposal, let’s start by defining feacal sludge (also spelt “fecal”). Thankfully, that’s easy. Wikipedia tells us: Fecal sludge management (FSM) (or faecal sludge management in British English) is the collection, transport, and treatment of fecal sludge from pit latrines, septic tanks or […]
CCC Net Zero Report by 2050 ADBA Responds with Support
In the “CCC Net Zero Report“, the IPCC says global greenhouse gas emissions need to reach “net zero” around 2050. To achieve the net-zero target tens of billions of pounds will need to be invested in renewable energy, electric vehicles, capturing and storing carbon emissions, and planting trees, according to the CCC. Currently the UK […]
