Isfahan Waste Management
Isfahan City Waste Management Organization is an integrated waste management system formed in 2003 under the responsibility of the Urban Services of the Municipality of Isfahan, Iran. Operations The organization employs 140 people who are tasked with handling Isfahan's approximately 950 tons of daily waste. This includes an estimate of 67 grams per-capita, 15 tons of hospital waste, and 4,000 tons of construction waste. After processing and separating recyclable items, garbage is divided into two main categories: organic and inorganic waste. On normal days, Isfahan's garbage is collected every two days. Recycling 12% of Isfahan's produced waste is recycled. Throughout the city, there are seventy recycling booths and stations. Composting Isfahan's organic fertilizer factory was established in 1947 by a Swiss organization. The current factory was built in 1968 on a land of about 100 hectares, located in "Zinel Neck", an area in the east of the city. Sustainability in ...

Waste Management
Waste management or waste disposal includes the processes and actions required to manage waste from its inception to its final disposal. This includes the collection, transport, treatment, and disposal of waste, together with monitoring and regulation of the waste management process and waste-related laws, technologies, and economic mechanisms. Waste can either be solid, liquid, or gases and each type has different methods of disposal and management. Waste management deals with all types of waste, including industrial, chemical, municipal, organic, biomedical, and radioactive wastes. In some cases, waste can pose a threat to human health. Health issues are associated with the entire process of waste management. Health issues can also arise indirectly or directly: directly through the handling of solid waste, and indirectly through the consumption of water, soil, and food. Waste is produced by human activity, for example, the extraction and processing of raw mater ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isfahan
Isfahan or Esfahan ( ) is a city in the Central District (Isfahan County), Central District of Isfahan County, Isfahan province, Iran. It is the capital of the province, the county, and the district. It is located south of Tehran. The city has a population of approximately 2,220,000, making it the third-most populous city in Iran, after Tehran and Mashhad, and the second-largest metropolitan area. Isfahan is located at the intersection of the two principal routes that traverse Iran, north–south and east–west. Isfahan flourished between the 9th and 18th centuries. Under the Safavid Iran, Safavid Empire, Isfahan became the capital of Iran, for the second time in its history, under Abbas the Great. It is known for its Persian architecture, Persian–Islamic architecture, Muslim architecture, grand boulevards, covered bridges, palaces, tiled mosques, and minarets. Isfahan also has many historical buildings, monuments, paintings, and artifacts. The fame of Isfahan led to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Municipality Of Isfahan
The Municipality of Isfahan is responsible for the management of the city of Isfahan, Isfahan Province, Iran. The highest-ranking official of this organization is the mayor of Isfahan, who is chosen by the Islamic City Council of Isfahan. The city of Isfahan has 15 administrative divisions and each division has its own mayor, who work under the mayor of Isfahan. The present mayor of Isfahan is Ali Ghasemzadeh. History The municipality of Isfahan was founded in 1907. In that time, it was named ''Baladiyeh''. The council of Baladiyeh appointed ''Haji Mohammad Ali Khan'' (The sheriff of Isfahan) as the chief of Baladiyeh, ''Mirza Mehdi Khan'' as the deputy and ''Mirza Abolhasan Khan'' for official services. But after two weeks, ''Haji Mohammad Ali Khan'' was replaced by ''Mirza Assadollah Vassigholmilk''. Baladiyeh had at first only 25 members. In 1911, the Baladiyeh faced a financial crisis because of shortage of income and the chief of Baladieyeh resigned and council of Baladiyeh ...

Organic Waste
Biodegradable waste includes any organic matter in waste which can be broken down into carbon dioxide, water, methane, compost, humus, and simple organic molecules by micro-organisms and other living things by composting, aerobic digestion, anaerobic digestion or similar processes. It mainly includes kitchen waste (spoiled food, trimmings, inedible parts), ash, soil, dung and other plant matter. In waste management, it also includes some inorganic materials which can be decomposed by bacteria. Such materials include gypsum and its products such as plasterboard and other simple sulfates which can be decomposed by sulfate reducing bacteria to yield hydrogen sulfide in anaerobic land-fill conditions. In domestic waste collection, the scope of biodegradable waste may be narrowed to include only those degradable wastes capable of being handled in the local waste handling facilities. To address this, many local waste management districts are integrating programs related to sort t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inorganic Waste
Inorganic waste is a type of waste that does not contain organic compounds. This waste is generally very difficult to decompose by microorganisms. Glass, aluminum cans, dust, and metal A metal () is a material that, when polished or fractured, shows a lustrous appearance, and conducts electrical resistivity and conductivity, electricity and thermal conductivity, heat relatively well. These properties are all associated wit ... are some examples of inorganic waste. Inorganic waste remains free from decay, with more than 500 years needed being common for effective decomposition, therefore disposal can be challenging. Reducing consumption, reusing, and recycling are possible solutions for coping with this type of waste. References {{reflist, 30em Waste ...

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 ...

Biogas
Biogas is a gaseous renewable energy source produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste, Wastewater treatment, wastewater, and food waste. Biogas is produced by anaerobic digestion with anaerobic organisms or methanogens inside an Anaerobic digestion, anaerobic digester, biodigester or a bioreactor. The gas composition is primarily methane () and carbon dioxide () and may have small amounts of hydrogen sulfide (), 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. After removal of carbon dioxide and hydrogen sulfide it can be compressed natural gas, compressed in the same way as natural gas and used to power Alternative fuel vehicle, motor vehicles.
