The Leo Group
The Leo Group is a privately owned, waste-recycling company based in Halifax, England that specialises in the collection and processing of animal by-products. The company is currently run by Daniel Sawrij, the managing director, who took over from the company's founders, his parents Margaret and Leo Sawrij, in 1988. History The Leo Group was founded in the 1970s by Margaret and Leo Sawrij and was originally named Swalesmoor Mink Farm. The couple bought a 10-acre farm in Halifax in 1971 and began breeding minks and foxes for the fur industry. Following the prohibition of mink farming in the UK and the handover to Daniel Sawrij, the company turned its focus to selling maggots to fishing tackle shops, soon becoming the biggest producer of maggots supplying seven thousand gallons of maggots a week to Belgium, Germany, Italy, Netherlands and France At the same time, the company began mixing food for small pet food companies. In 1993, Daniel Sawrij sold 90 percent of his beef cattle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halifax, West Yorkshire
Halifax is a town in the Metropolitan Borough of Calderdale, in West Yorkshire, England. It is in the eastern foothills of the Pennines. In the 15th century, the town became an economic hub of the old West Riding of Yorkshire, primarily in woollen manufacture with the large Piece Hall square later built for trading wool in the town centre. The town was a thriving mill town during the Industrial Revolution with the Dean Clough Mill buildings a surviving landmark. In 2021, it had a population of 88,109. It is also the administrative centre of the wider Calderdale Metropolitan Borough. Toponymy The town's name was recorded in about 1091 as ''Halyfax'', most likely from the Old English ''halh-gefeaxe'', meaning "area of coarse grass in the of land".

The probably-incorrect interpretation gave rise to two legends. One concern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biomass
Biomass is a term used in several contexts: in the context of ecology it means living organisms, and in the context of bioenergy it means matter from recently living (but now dead) organisms. In the latter context, there are variations in how biomass is defined, e.g., only from plants, from plants and algae, from plants and animals. The vast majority of biomass used for bioenergy does come from plants and fecal matter. Bioenergy is a type of renewable energy that the bioenergy industry claims has the potential to assist with climate change mitigation. Uses in different contexts Ecology * Biomass (ecology), the mass of living biological organisms in a given area or ecosystem at a given time. This can be the biomass of particular species or the biomass of a particular community or habitat. Energy * Biomass (energy), biomass used for energy production or in other words: biological mass used as a renewable energy source (usually produced through agriculture, forestry or ...

Denholme
Denholme is a town and civil parish in the Bradford Metropolitan Borough, West Yorkshire, England. It is west of Bradford, from Keighley and roughly the same distance from Halifax. Administratively, it is part of the Bingley Rural ward of the City of Bradford. Denholme had a population of 2,976 in 2001, this had increased to 3,489 at the 2011 Census. History The name Denholme is probably of Viking origin, translating to "A flat amongst the hillside". This is a good description of the town's geographical setting, since it is located in a broad side valley extending southwards from that of the River Aire - the Aire Valley or Airedale. However, an alternative suggestion of the word "Holme", in old Viking Danelaw, would be that of reclaimed marshland (or an "island" in a wet area) and Den or Denu, in Old English, means Valley. This would also make sense given the areas many springs, marshy terrain and situation in a valley. Denholme is also on the eastern flank of the Penn ...

Anaerobic Digestion
Anaerobic digestion is a sequence of processes by which microorganisms break down biodegradable material in the absence of oxygen. The process is used for industrial or domestic purposes to Waste management, manage waste or to produce fuels. Much of the Fermentation (biochemistry), fermentation used industrially to produce food and drink products, as well as home fermentation, uses anaerobic digestion. Anaerobic digestion occurs naturally in some soils and in lake and oceanic basin sediments, where it is usually referred to as "anaerobic activity". This is the source of Methane#Occurrence, marsh gas methane as discovered by Alessandro Volta in 1776. Anaerobic digestion comprises four stages: * Hydrolysis *Acidogenesis *Acetogenesis *Methanogenesis The digestion process begins with bacterial hydrolysis of the input materials. Insoluble organic polymers, such as carbohydrates, are broken down to soluble derivatives that become available for other bacteria. Acidogenesis, Acidogen ...

Biodiesel
Biodiesel is a renewable biofuel, a form of diesel fuel, derived from biological sources like vegetable oils, animal fats, or recycled greases, and consisting of long-chain fatty acid esters. It is typically made from fats. The roots of biodiesel as a fuel source can be traced back to when J. Patrick and E. Duffy first conducted transesterification of vegetable oil in 1853, predating Rudolf Diesel's development of the diesel engine. Diesel's engine, initially designed for mineral oil, successfully ran on peanut oil at the 1900 Paris Exposition. This landmark event highlighted the potential of vegetable oils as an alternative fuel source. The interest in using vegetable oils as fuels resurfaced periodically, particularly during resource-constrained periods such as World War II. However, challenges such as high viscosity and resultant engine deposits were significant hurdles. The modern form of biodiesel emerged in the 1930s, when a method was found for transforming vegetable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other Chemical element, elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat which is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous (Pennsylvanian (geology), Pennsylvanian) and Permian times. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its Electricity generation, electricity.
