Biogas
Biogas is a gaseous renewable energy source[1] produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste, wastewater, and food waste. Biogas is produced by anaerobic digestion with anaerobic organisms or methanogens inside an anaerobic digester, biodigester or a bioreactor.[2] The gas composition is primarily methane (CH
4) and carbon dioxide (CO
2) and may have small amounts of hydrogen sulfide (H
2S), moisture and siloxanes. The methane can be combusted or oxidized with oxygen. This energy release allows biogas to be used as a fuel; it can be used in fuel cells and for heating purpose, such as in cooking. It can also be used in a gas engine to convert the energy in the gas into electricity and heat.[3]
After removal of carbon dioxide and hydrogen sulfide it can be compressed in the same way as natural gas and used to power motor vehicles. In the United Kingdom, for example, biogas is estimated to have the potential to replace around 17% of vehicle fuel.[4] It qualifies for renewable energy subsidies in some parts of the world. Biogas can be cleaned and upgraded to natural gas standards, when it becomes bio-methane. Biogas is considered to be a renewable resource because its production-and-use cycle is continuous, and it generates no net carbon dioxide. From a carbon perspective, as much carbon dioxide is absorbed from the atmosphere in the growth of the primary bio-resource as is released, when the material is ultimately converted to energy.
North Lincolnshire is a unitary authority area with borough status in Lincolnshire, England. At the 2011 Census, it had a population of 167,446.[2] The administrative centre and largest settlement is Scunthorpe, and the borough also includes the towns of Brigg, Broughton, Haxey, Crowle, Epworth, Bottesford, Winterton, Kirton in Lindsey and Barton-upon-Humber. North Lincolnshire is part of the Yorkshire and the Humber region. The borough is mostly rural in character aside from near the town of Scunthorpe and near the Port of Immingham where most of the nearby villages and towns form part of the wider urban areas.
North Lincolnshire was formed following the abolition of Humberside County Council in 1996, when four unitary authorities replaced it, North Lincolnshire and North East Lincolnshire, on the south bank of the Humber Estuary, and the East Riding of Yorkshire and Kingston upon Hull on the north bank.

It is home to the Haxey Hood, a traditional event which takes place in Haxey on 6 January, a large football scrum where a leather tube (the "hood") is pushed to one of four pubs, where it remains until next year's game.
