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.
Worksop (/ˈwɜːrksɒp/ WURK-sop) is the largest town in the Bassetlaw district of the ceremonial county of Nottinghamshire in the East Midlands of England. Worksop lies on the River Ryton, and is located at the northern edge of Sherwood Forest. Worksop is located 19 miles (31 km) east-south-east of Sheffield, with a population of 41,820.[2] It lies close to Nottinghamshire’s borders with South Yorkshire, and Derbyshire.
Worksop, a market town, has become a commuter town as a result of its geographic location and ease of access to major motorways and rail links.
Worksop is known as the "Gateway to The Dukeries", because of the now four obsolete ducal principal sites of which were closely located next to each other, south of the town. These four ducal locations were; Clumber House, Thoresby Hall, Welbeck Abbey and Worksop Manor. Other houses such as Rufford Abbey and Hodsock Priory are also just a few miles away.
Worksop is twinned with the German town Garbsen.
