Biogas refers to a mixture of different gases produced by the breakdown of organic matter in the absence of oxygen. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. Biogas is a renewable energy source.
A dairy is a business enterprise established for the harvesting or processing of animal milk – mostly from cows or goats, but also from buffaloes, sheep, horses, or camels – for human consumption. A dairy is typically located on a dedicated dairy farm or in a section of a multi-purpose farm that is concerned with the harvesting of milk.
A landfill site is a site for the disposal of waste materials by burial. It is the oldest form of waste treatment. Historically, landfills have been the most common method of organized waste disposal and remain so in many places around the world.
Garbage truck or dustcart refers to a truck specially designed to collect municipal solid waste and haul the collected waste to a solid waste treatment facility such as a landfill. Other common names for this type of truck include trash truck in the United States, and rubbish truck, junk truck, dumpster, bin wagon, dustbin lorry, bin lorry or bin van elsewhere. Technical names include waste collection vehicle and refuse collection vehicle. These trucks are a common sight in most urban areas.
Vicia cracca, is a species of vetch native to Europe and Asia. It occurs on other continents as an introduced species, including North America, where it is a common weed. It often occurs in disturbed habitats, including old fields and roadside ditches.
A waste-to-energy plant is a waste management facility that combusts wastes to produce electricity. This type of power plant is sometimes called a trash-to-energy, municipal waste incineration, energy recovery, or resource recovery plant.
Illegal dumping, also called fly dumping or fly tipping, is the dumping of waste illegally instead of using an authorised method such as kerbside collection or using an authorised rubbish dump. It is the illegal deposit of any waste onto land, including waste dumped or tipped on a site with no licence to accept waste. The United States Environmental Protection Agency developed a “profile” of the typical illegal dumper. Characteristics of offenders include, local residents, construction and landscaping contractors, waste removers, scrap yard operators, and automobile and tire repair shops.
A skip is a large open-topped waste container designed for loading onto a special type of lorry. Instead of being emptied into a bin lorry on site, as a wheelie bin is, a skip is removed, or replaced by an empty skip, and then tipped at a landfill site or transfer station.
In the context of physical construction, deconstruction is the selective dismantlement of building components, specifically for re-use, repurposing, recycling, and waste management. It differs from demolition where a site is cleared of its building by the most expedient means. Deconstruction has also been defined as “construction in reverse”. The process of dismantling structures is an ancient activity that has been revived by the growing field of sustainable, green method of building. Buildings, like everything, have a life-cycle. Deconstruction focuses on giving the materials within a building a new life once the building as a whole can no longer continue.
Waste collection is a part of the process of waste management. It is the transfer of solid waste from the point of use and disposal to the point of treatment or landfill. Waste collection also includes the curbside collection of recyclable materials that technically are not waste, as part of a municipal landfill diversion program.
Eco-Schools is an international programme of the Foundation for Environmental Education (FEE) that aims to empower students to be the change our sustainable world needs by engaging them in fun, action-orientated and socially responsible learning.
The Rokkaku dako (六角凧) is a traditional six-sided Japanese fighter kite. Traditionally, it is made with bamboo spars and washi paper. The rokkaku kite is often hand painted with the face of a famous Samurai. The structure is a vertically stretched hexagon with a four-point bridle. One bamboo runs from tip to toe, and there are two cross-spars. Flown on a taut string, the kite is stable and rises rapidly. When the line is released, the kite tumbles until tension is put on the line, at which point it takes off in the direction of the spine. Fighting two or more of these kites involves tipping over or destabilizing the opposing kite or cutting its kite line or bridle. Cows are often painted on kites to resemble wealth.
The Gover Stream is an approximately 3 kilometres (1.9 mi) long stream located in mid south Cornwall, England, United Kingdom.
Rates of household recycling in Ireland have increased dramatically since the late 1990s. The Irish Environmental Protection Agency (EPA) is the agency with overall responsibility for environmental protection in the Republic of Ireland and monitors rates of recycling in Ireland along with other measures of environmental conditions in Ireland. The EPA, along with Repak, the principal organisation for packaging recycling in Ireland, report on recycling rates each year. In 2012 Ireland’s MSW recycling rate was 34%, while the rate of packaging recycling reached 79%. The amount of municipal waste generated per person per year in the Republic of Ireland has fallen significantly in recent years. This figure remains above the European Union annual municipal waste average of 503 kg per person however.
Each local council in Ireland has considerable control over recycling, so recycling practices vary to some extent across the country. Most waste that is not recycled is disposed of in landfill sites.
A trickling filter is a type of wastewater treatment system. It consists of a fixed bed of rocks, coke, gravel, slag, polyurethane foam, sphagnum peat moss, ceramic, or plastic media over which sewage or other wastewater flows downward and causes a layer of microbial slime (biofilm) to grow, covering the bed of media. Aerobic conditions are maintained by splashing, diffusion, and either by forced-air flowing through the bed or natural convection of air if the filter medium is porous.
Xtreme Zero Waste is a non-profit organization dedicated to recycling and based in the town of Raglan, New Zealand. In 2014 it was rebranded from Xtreme Waste. According to its mission statement, its goal is to create a waste management system for the Raglan/Whaingaroa community in which none of the trash would be stored in landfills.
Monty Python's Cow Tossing is a catapult-physics game. It was developed by South African studio Luma Arcade and released by Zed Worldwide on February 3, 2011 for Android, iOS, and J2ME. The game is similar in style to Angry Bird and Crush the Castle, and includes the premise of firing cows at Englishmen who are located in structures built of concrete, wood, and other materials. It is based on the film Monty Python and the Holy Grail "in which French militiamen hurl a heifer onto a band of English relic seekers", and to further tie-in to the movie, "funny quotes from the movie appear in bubbles over the characters".
Digeponics (pronounced die-jeh-ponics, as in digestion) is a method of agriculture which integrates the products of anaerobic digestion, including CO2 and digestate, with greenhouse cultivation of vegetables.
