Garbage Compactor
A compactor is a machine or mechanism used to reduce the size of material such as waste material or bio mass through compaction. A trash compactor is often used by a home or business to reduce the volume of trash it produces. A baler-wrapper compactor is often used for making compact and wrapped bales in order to improve logistics. Normally powered by hydraulics, compactors take many shapes and sizes. In landfill sites for example, a large tractor (typically a converted front end loader with some variant of a bulldozer blade attached) with spiked steel wheels called a landfill compactor is used to drive over waste deposited by waste collection vehicles (WCVs). WCVs themselves incorporate a compacting mechanism which is used to increase the payload of the vehicle and reduce the number of times it has to empty. This usually takes the form of hydraulically powered sliding plates which sweep out the collection hopper and compress the material into what has already been loaded. Diff ...

Caterpillar 825G Soil Compactor
Caterpillars ( ) are the larval stage of members of the order Lepidoptera (the insect order comprising butterflies and moths). As with most common names, the application of the word is arbitrary, since the larvae of sawflies (suborder Symphyta) are commonly called caterpillars as well. Both lepidopteran and symphytan larvae have eruciform body shapes. Caterpillars of most species eat plant material ( often leaves), but not all; some (about 1%) eat insects, and some are even cannibalistic. Some feed on other animal products. For example, clothes moths feed on wool, and horn moths feed on the hooves and horns of dead ungulates. Caterpillars are typically voracious feeders and many of them are among the most serious of agricultural pests. In fact, many moth species are best known in their caterpillar stages because of the damage they cause to fruits and other agricultural produce, whereas the moths are obscure and do no direct harm. Conversely, various species of caterpilla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landfill Compactor
A landfill site, also known as a tip, dump, rubbish dump, garbage dump, or dumping ground, is a site for the disposal of waste materials. Landfill is the oldest and most common form of waste disposal, although the systematic burial of the waste with daily, intermediate and final covers only began in the 1940s. In the past, refuse was simply left in piles or thrown into pits; in archeology this is known as a midden. Some landfill sites are used for waste management purposes, such as temporary storage, consolidation and transfer, or for various stages of processing waste material, such as sorting, treatment, or recycling. Unless they are stabilized, landfills may undergo severe shaking or soil liquefaction of the ground during an earthquake. Once full, the area over a landfill site may be reclaimed for other uses. Operations Operators of well-run landfills for non-hazardous waste meet predefined specifications by applying techniques to: # confine waste to as small an area as ...

Crusher
A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated. Crushing is the process of transferring a force amplified by mechanical advantage through a material made of molecules that bond together more strongly, and resist deformation more, than those in the material being crushed do. Crushing devices hold material between two parallel or tangent solid surfaces, and apply sufficient force to bring the surfaces together to generate enough energy within the material being crushed so that its molecules separate from (fracturing), or change alignment in relation to (deformation), each other. The earliest crushers were hand-held stones, where the weight of the stone provided a boost ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road Roller
A road roller (sometimes called a roller-compactor, or just roller) is a compactor-type engineering vehicle used to compact soil, gravel, concrete, or asphalt in the construction of roads and foundations. Similar rollers are used also at landfills or in agriculture. Road rollers are frequently referred to as steamrollers, regardless of their method of propulsion. History The first road rollers were horse-drawn, and were probably borrowed farm implements'' (see Roller)''. Since the effectiveness of a roller depends to a large extent on its weight, self-powered vehicles replaced horse-drawn rollers from the mid-19th century. The first such vehicles were steam rollers. Single-cylinder steam rollers were generally used for base compaction and run with high engine revs with low gearing to promote bounce and vibration from the crankshaft through to the rolls in much the same way as a vibrating roller. The double cylinder or compound steam rollers became popular from around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Construction
Construction is a general term meaning the art and science to form objects, systems, or organizations,"Construction" def. 1.a. 1.b. and 1.c. ''Oxford English Dictionary'' Second Edition on CD-ROM (v. 4.0) Oxford University Press 2009 and comes from Latin ''constructio'' (from ''com-'' "together" and ''struere'' "to pile up") and Old French ''construction''. To construct is the verb: the act of building, and the noun is construction: how something is built, the nature of its structure. In its most widely used context, construction covers the processes involved in delivering buildings, infrastructure, industrial facilities and associated activities through to the end of their life. It typically starts with planning, financing, and design, and continues until the asset is built and ready for use; construction also covers repairs and maintenance work, any works to expand, extend and improve the asset, and its eventual demolition, dismantling or decommissioning. The constructio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Refuse-derived Fuel
Refuse-derived fuel (RDF) is a fuel produced from various types of waste such as municipal solid waste (MSW), industrial waste or commercial waste. The World Business Council for Sustainable Development provides a definition: ''"Selected waste and by-products with recoverable calorific value can be used as fuels in a cement kiln, replacing a portion of conventional fossil fuels, like coal, if they meet strict specifications. Sometimes they can only be used after pre-processing to provide ‘tailor-made’ fuels for the cement process".'' RDF consists largely of combustible components of such waste, as non recyclable plastics (not including PVC), paper cardboard, labels, and other corrugated materials. These fractions are separated by different processing steps, such as screening, air classification, ballistic separation, separation of ferrous and non ferrous materials, glass, stones and other foreign materials and shredding into a uniform grain size, or also pelletized in ord ...

Waste Collector
A waste collector, also known as a garbageman, garbage collector, trashman (in the US), binman or (rarely) dustman (in the UK), is a person employed by a public or private enterprise to collect and dispose of municipal solid waste (refuse) and recyclables from residential, commercial, industrial or other collection sites for further processing and waste disposal. Specialised waste collection vehicles (also known as garbage trucks in the US, bin lorries in the UK) featuring an array of automated functions are often deployed to assist waste collectors in reducing collection and transport time and for protection from exposure. Waste and recycling pickup work is physically demanding and usually exposes workers to an occupational hazard. The first known waste collectors were said to come from Britain in the 1350s, coinciding with the Black Plague and were called "rakers." A related occupation is that of a sanitation worker who operates and maintains sanitation technology.World Bank, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Memphis Sanitation Strike
The Memphis sanitation strike began on February 12, 1968, in response to the deaths of sanitation workers Death of Echol Cole and Robert Walker, Echol Cole and Robert Walker.Estes, S. (2000). `I AM A MAN A MAN?’: Race, Masculinity, and the 1968 Memphis Sanitation Strike. ''Labor History'', ''41''(2), 153. https://doi.org/10.1080/00236560050009914 The deaths served as a breaking point for more than 1,300 African American men from the Memphis Department of Public Works as they demanded higher wages, time and a half overtime, dues check-off, safety measures, and pay for the rainy days when they were told to go home. The Memphis sanitation strike was led by T.O. Jones and had the support of Jerry Wurf, president of the American Federation of State, County and Municipal Employees, American Federation of State, County, and Municipal Employees (AFSCME) and the local branch of the NAACP, National Association for the Advancement of Colored People (NAACP).

Civil Rights Movement
The civil rights movement was a nonviolent social and political movement and campaign from 1954 to 1968 in the United States to abolish legalized institutional Racial segregation in the United States, racial segregation, Racial discrimination in the United States, discrimination, and disenfranchisement in the United States, disenfranchisement throughout the United States. The movement had its origins in the Reconstruction era during the late 19th century, although it made its largest legislative gains in the 1960s after years of direct actions and grassroots protests. The social movement's major nonviolent resistance and civil disobedience campaigns eventually secured new protections in federal law for the civil rights of all Americans. After the American Civil War and the subsequent Abolitionism in the United States, abolition of slavery in the 1860s, the Reconstruction Amendments to the United States Constitution granted emancipation and constitutional rights of citizenship ...

Garbage Trucks
A garbage truck is a truck specially designed to collect municipal solid waste and transport it to a solid waste treatment facility, such as a landfill, recycling center or transfer station. In Australia they are commonly called rubbish trucks, or garbage trucks, while in the U.K. dustbin lorry or bin lorry is commonly used. Other common names for this type of truck include trash truck in the United States, and refuse truck, dustcart, junk truck, bin wagon or bin van elsewhere. Technical names include waste collection vehicle and refuse collection vehicle (RCV). These trucks are a common sight in most urban areas. History Wagons and other means had been used for centuries to haul away solid waste. Among the first self-propelled garbage trucks were those ordered by Chiswick District Council from the Thornycroft Steam Wagon and Carriage Company in 1897 described as a steam motor tip-car, a new design of body specific for "the collection of dust and house refuse".

Solar-powered Trash Compactor
A solar-powered waste compactor is a smart device that reads a waste bin's fill-level in real-time and triggers an automatic compaction of the waste, effectively increasing the bin's capacity by up to 5-8 times. The compaction mechanism runs on a battery, which is charged by the solar panel A solar cell panel, solar electric panel, photo-voltaic (PV) module, PV panel or solar panel is an assembly of photovoltaic solar cells mounted in a (usually rectangular) frame, and a neatly organised collection of PV panels is called a photo .... Fully charged, the battery reserve lasts for approximately 3–4 weeks depending on the compaction frequency and usage patterns. Solar-powered waste compactors are typically connected to a remote software platform through wireless 2G/3G networks. The platform enables waste collection managers to access real-time data analytics and route optimization. Solar-powered compactors are primarily used in high foot traffic areas such as town centers, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
