Rotowaro Carbonisation Plant
The Rotowaro Carbonisation Plant, also known as the Waikato Carbonisation Plant, was a coal processing plant in the Rotowaro/Huntly area, New Zealand. It was also the first plant to use the Lurgi process in the Southern Hemisphere. History The first of its kind in the Southern Hemisphere, the plant was constructed in the late 1930s to convert otherwise unusable low-quality coal from the nearby Rotowaro Coal Mines into carbon briquettes, which were then used for domestic heating. The coal was carbonised using the Lurgi process, the result being coke and charcoal, with tar and creosote as by-products. The tar was used with the char to create the briquettes. Waste from the plant was discharged directly into the nearby Awaroa stream, which caused heavy pollution of the waterway. Following complaints about the pollution, Waikato Carbonisation Limited trialed a waste incineration programme, but the output of the plant exceeded the capacity of the burners. The excess was pumped into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Huntly, New Zealand
Huntly ( mi, Rahui-Pōkeka) (population ) is a town in the Waikato district and region of the North Island of New Zealand. It was on State Highway 1 (until Huntly bypass opened in March 2020), south of Auckland and north of Hamilton. It is situated on the North Island Main Trunk (NIMT) railway (served by Te Huia since 6 April 2021 at a rebuilt Raahui Pookeka-Huntly Station) and straddles the Waikato River. Huntly is within the Waikato District which is in the northern part of the Waikato region local government area. History and culture Originally settled by Māori, European migrants arrived in the area some time in the 1850s. The Huntly name was adopted in the 1870s when the postmaster named it after Huntly, Aberdeenshire in Scotland. He used an old 'Huntley Lodge' stamp to stamp mail from the early European settlement. The ''Lodge'' was later dropped and the spelling changed to also drop the additional 'e'. The railway from Auckland reached Huntly in 1877, w ...

Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as stratum, 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 formed when dead plant matter decays into peat and 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. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. 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 energ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotowaro
Rotowaro was once a small coal mining township approximately 10 km west of Huntly in the Waikato region of New Zealand. The town was built especially for miners houses, but was entirely removed in the 1980s to make way for a large opencast mine. The New Zealand Ministry for Culture and Heritage gives a translation of "lake of glowing embers" for . History Mining by Taupiri Coal Co began in Rotowaro around 1915 after a railway to the area and a bridge over the Waikato River were completed. In 1928 it was producing 11,000 tons of coal a month. The current open cast working and the much smaller O'Reilly's, Puke Coal and Maramarua are the only remaining mines in the Waikato coalfield. It opened in 1958 and produces about 700,000 tonnes a year to make steel at Glenbrook and for limeworks, meat works, timber processing, light industry and horticulture. It was sold by Solid Energy to Bathurst Resources and Talleys in 2016. The Rotowaro Class A train station was opened ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 List of islands of New Zealand, smaller islands. It is the List of island countries, sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's Capital of New Zealand, capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Briquettes
A briquette (; also spelled briquet) is a compressed block of coal dust or other combustible biomass material (e.g. charcoal, sawdust, wood chips, peat, or paper) used for fuel and kindling to start a fire. The term derives from the French word ''brique'', meaning ''brick''. Coal briquettes Coal briquettes have long been produced as a means of using up 'small coal', the finely broken coal inevitably produced during the mining process. Otherwise this is difficult to burn as it is hard to arrange adequate airflow through a fire of these small pieces; also such fuel tends to be drawn up and out of the chimney by the draught, giving visible black smoke. The first briquettes were known as culm bombs and were hand-moulded with a little wet clay as a binder. These could be difficult to burn efficiently, as the unburned clay produced a large ash content, blocking airflow through a grate. With Victorian developments in engineering, particularly the hydraulic press, it became possib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hazardous Waste
Hazardous waste is waste that has substantial or potential threats to public health or the environment. Hazardous waste is a type of dangerous goods. They usually have one or more of the following hazardous traits: ignitability, reactivity, corrosivity, toxicity. Listed hazardous wastes are materials specifically listed by regulatory authorities as hazardous wastes which are from non-specific sources, specific sources, or discarded chemical products. Hazardous wastes may be found in different physical states such as gaseous, liquids, or solids. A hazardous waste is a special type of waste because it cannot be disposed of by common means like other by-products of our everyday lives. Depending on the physical state of the waste, treatment and solidification processes might be required. The Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and Their Disposal was signed by 199 countries and went into force in 1992. Plastic was added to the conventio ...
