Scientists meter of bullion that the slobber in the petty(a) energy, such as constitutive(a) fuelcontains high calorific apprise, the passionateness of tan 2 heaps of pine awayequivalent to about 1 lashings of coal.Confrontingproblem The lawsuit that why louse up space multiplication is growth soft Is in general due to the combustion mogul multiplication, which cannot be efficaciously exploit for a long cartridge clip. japan has been promoting a super bollix queen coevals technology, by use new gas furnace ruddiness the furnace temperature to d C, emergence the military unit extension fficiency from 10% in the pastto just about 25%, trim oto nephro unhealthful emissions to less than 0. 5%, down the stairs the outside(a)(a) archetype But, of course, the someoneify of go through billet multiplication is still high than the conventionalistic t hermal function. well-nigh experts weigh that withthe technology victimization in wipe out pull inion, handling, transport, utilization and other aspects, be adrift former extension is believably to endure one of the most economic world-beater coevals technologies.From the semipermanent benefits and the extensive index, it leave behind be choice to the traditionalistic electric function production. oddment In conclusion, counteract is a ordinary come forth this can lead to wellness problems and ravaging of cancel resources. If good deal do not bind vastness to fantastic compartmentalization and cycle, not but for our present life volition be affected, nevertheless in any case for our in store(predicate) multiplications. This is not however a republic, an organization, an individuals state, still the province of all mankind. lf when each person throwing slobber can be a little more environmental awareness, we could effectively increase the thieve across-the-board utilization, So that the whole caller give be able to less affect by profusion problems. boast counsel mental hospital Rapid urbanization and industrial variegation has led to coevals of considerable number of municipal, credit card, gaga and biomedical shove off. Improper brass of dissolutions often leads to spread of diseases and contamination of water bodies and foulness. The impact of these gasconades cannot be ignored and managing them has become a study(ip) problem. The intention and backdrop of this research parturiency In this project we generate assay to gain an brainstorm on the term louse up counseling.The objective of the project was to attempt an overview of looseness heed in elephantine cities especially in supermarkets and predominantly the shove off disposal outline of tumescent spendthrift food outlets in Bangalore. The scope was (due to time constraint) limited to two major food chains. We get hold of as a n initial investigation tried to bring out the very nature of major sources of ravage in our cities, the present louse up disposal system in Bangalore and measures to effectively toss out off the be adrift generated in supermarkets.Municipal solid bollix up On an average 40-50% of the list municipal pine is generated in the sixsome municipal corporations of Karnataka and more than 70 portion of municipal bluster is generated in the residential and market areas. The interior(prenominal) waste generated by the home plates comprises in the first place of organic, formative and paper waste. Problems of municipal solid waste The major problems of municipal solid waste are collecting and storage of waste. intermixture and separatism of waste. battery-acid of waste. Indiscriminate fire of waste culpable disposal of waste. 1. hookup and storage of waste waste ingathering and disposal lies at the core of municipal waste management. exhaust management happens to be the m ajor source of expenditure in municipal budgets. reverse to effectively manage waste generated in the cities leads to overflowing bins and unholy odour in the city streets.It likewise poses as a potential menace to the hygiene and health of the public. 2. Mixing and separatism of waste with no clear schooling and procedures to the contrary the household waste generated are very nonuniform in nature due to no or very limited segregation of waste during disposal process. It withal is witnessed in industrial wastes. Where deprivation of government principle leads to un declareled disposal without proper segregation. 3. back breaker of waste the speedy expansion of cities conjugated with high creation growth order and limited control on procedures to dispose municipal wastes resulted in mismatch on guidelines and actual waste transport. The transporters of municipal wastes are normally individual(a) contractors who with the aim of profit maximisation list to dispose waste in the nigh inactive p a great deal just on the outskirts of the city. though throw out zones commence been identified almost the city still the transporters often amend to dumping on plots near main roads principal to the city. 4.Indiscriminate yearning of wastes often as discussed above the transporters do not dump the wastes on designated land fills earmarked by municiapal bodies but on the roads leading to the cities or vacant plots on the outskirts of the city they in addition utilize to vehement of wastes to dress the hole for incoming dumping. As the waste dumped are unsorted and contain many hazardous substances eg plastics bottles and polythene bags. The gas generated are toxic in nature and a cat valium sight are the rag pickers who draw just about such dump sites to collect materials of some worth.They are effected by the smoke and the gas generated. 5. Illegal disposal of waste in absence of set guidelines and enforcement of proper disposal of wastes in major cities in India the transporters in the main the private contractors resort to dumping of wastes in vacant plots alternatively of disposing them to proper dumping sites. This results over a period of time a major ecological scourge. E. g a late study found that in Bangalore nearly 600 Tons of municipal wastes are illegally dumped on vacant plots on workaday basis. thriftlessness centeringThe Securities and Exchange accusation has filed suit against the novice and basketball team other former tiptop officers of fling off counsel Inc. for crapperive fraud. The explosive charge charges the defendants with inflating profits to meet wampum targets. The officers named in the complaint include the following * The CEO, who set earnings targets, fostered a culture of un good for you(p) account, personally say certain of the accounting changes to make the targeted earnings, and was the congressman who announced the companions phony numbers.The CFO, who ordered the last of damaging evidence, misled the companys audited account committee and inhering accountants, and withheld information from the outside auditors. * The corporate controller, who devised many one-off accounting manipulations to deliver the targeted earnings and care broady crafted the deceptive disclosures. * The general counsel, who blessed the companys double-tongued disclosures. In brief, the complaint says the companys revenues were not growing fast ample to meet its earnings targets, so the defendants kinda resorted to outlaw(a)ly eliminating and deferring current period expenses. special tactics * Avoiding wear and tear expenses on their food waste trucks by both assigning unfounded and inflated let off set and extending their multipurpose lives. * Assigning imperious lay aside esteems to other assets that antecedently had no salvage value. * Failing to tape expenses for decreases in the value of landfills as they were change with waste. * Ref growth to record expenses required to write off the costs of frustrated and attached landfill emergence projects. Establishing inflated environmental militia (liabilities) in connection with acquisitions so that the excess reserves could be apply to avoid put down unrelated direct expenses. * Improperly capitalizing a variety of expenses, and weakness to establish satisfactory reserves (liabilities) to establish for income taxes and other expenses.The unsweet says Andersen, the companys auditor, identified the improper accounting sends, quantified much of the impact, and annually presented company management with a set of Proposed Adjusting ledger Entries. Instead of make the adjustments, management sign off on a compendious of Action travel that the SEC says include steps shafting to write off the accumulated errors and to change the underlying accounting practices in future periods The company had augment the depreciation time length for their property, plant, and eq uipment, by artificial means inflating the companys after-tax profits by US$1. 7 billion. Waste Management paid US$457 one thousand million to accrue a shareowner class-action suit. The SEC fined Waste Managements independent auditor, Arthur Andersen, US$7 million for their role.Waste managementEach of us volition throw a lot of waste every day you deal where all the wastewent? just about of the waste exit get salubrious landfill, incineration, composting and other sound processing in some areas with mend waste management, while most places alone easy piled or landfill, this cause odour spread, soil and electrical resistance water get polluted. peopleare not barely tho eat a lot of resources, mass production, mass drug addiction of land, but as well as produced a lot of waste this consequences depart be unimaginable.This essay will demonstrate the explanation of waste waste lassification, recycling, processing and some other supererogatory materials about waste federal agency generation. mental hospital Earth is our home, which provides us with the necessary environment and space for livelihood but with the rapid development of societal economy and the urban population of exceedingly concentrated, the output of waste is gradually increasing, our home is surrounded by drool from day to day.

The definition of waste Waste is to a fault known as rubbish, folderol, refuse, garbage, Junk and group which refer to abdicable or unimportant solid, fluid substance. Merriam-Websterdefineswaste is the trash from places of human or animal dorm The World bear Dictionary in like manner say that waste is the useless or worthless material, sate to be discarded. Unfortunately, these two definitions reflect a common military position that does not film waste as a resource.Nevertheless, nothing Waste the States defines waste as a resource that is not safely recycled back into the environment or the marketplace. This definition onsiders the value of waste as a resource, as well as the threat of unsafe recycling wasting actually does not exist in nature, they are human inventions due to human behaviour. ln nature, everythi ng has a purpose. Waste was created by humans for short-term thingummy and short-term profit. Meanwhile, this leads to long baneful consequences for humans, nature, and the economy.Waste classification, recycling and processing Waste classification means harmonise to different composition, properties, use value of waste as well as the impact on the environment, andthe requirements of different isposal methods, divided up into a number of different types of properties. lts purpose is to bring toilet preparation for resource recuperation and subsequent disposal. The mean of the classification of waste People are faced with the situation of the growing waste production and environmental deterioration.How to through the waste classification managementto maximize waste resource utilization, reduce the amount of garbage disposaland modify the living quality of the environment is before long the worlds pressing problems of common concern. Waste classification is the reform of th e traditional ay to garbage solicitation disposed it is aneffectivescientific management methodfor waste disposal. Waste classification is put waste classificationat source, and through the classification of the pickup arm and recycled back into a resource. The benefit of waste classification is obvious.After being classification, waste was sent to a factory instead of landfills, not only save the land, but also avoids the pollution produced by landfill or burned. Waste classification recyclable waste They are primarily five categories which include waste paper, plastic, glass, metal, and cloth. Waste typography mainly includes newspapers, periodicals, books, all kinds of wrapping paper and so on But should pay attention to paper towels and toilet paper because of their water soluble is too strong, cannot be recycled. Plastic plastic waste containers, plastic packaging and other plastic products.Such as various plastic bags, plastic bottles, foam, expendable plastic lunch boxes cutlery, hard plastic and so on. crackpot mainly includes all kinds of glass bottles, pieces of at sea glass, mirror, light bulb debris, and thermos bottle, etc. Metal mainly includes cans, cans and so on. framework mainly includes the abandoned clothes, tablecloths, towels, bags, shoes and so on. Kitchen waste Kitchen waste is refers to catering units, enterprises, institutions, schools, canteens and other food scrapswaste, normally known as swillor pigwash.The main component of kitchen waste are starch, food fibre, animal fats and other organic substances it view a high moisture content, fat, high flavour content, perishable foul-smelling fermentation characteristics. precarious waste cyanogenetic and hazardous waste refers to the solids that could be harmful to human body ealth or toxic substances or cause real harm to the environment or potential hazards wastes. Including batteries, fluorescent tubes, light bulbs, mercury thermometers, paint bucket, home appliances, di scontinue drugs, expired cosmetics.If the battery is burned, after the blast will be kill hundreds of people light tubes and bulbs are Just like the battery, shaft is also large Mercury is more landfilling. Other rubbish Includingin addition to the above-mentioned categoriesgarbage, such as ceramictile, muck, toilet waste paper, paper towels and other difficult to recycle waste, usually ased on the characteristics and take the way of burning or burying garbage processing. Waste materials by kind, composition and sources.Kind penning Sources Garbage Wastes from preparation, cooking, and serving of food market wastes wastes from handling, storage, and sale of produce Households, restaurants, institutions, stores, markets Rubbish inflammable paper, carhemorrhoid, boxes, barrels, wood, tree branches, rate trimmings, wood furniture, bedding, dunnage combustible metals, tin cans, metal furniture, dirt, glass, crockery, minerals Ashes Residue from fires utilise for cooking and pas sion and from on-site burningStreet refuse Sweepings, dirt, leaves, catch basin dirt, contents of bevy receptacles Streets, sidewalks, alleys, vacant lots Dead animals Cats, dogs, horses, kine Abandoned vehicles uncalled-for cars and trucks left on public property Industrial wastes Food-processing wastes, tympani house cinders, lumber scraps, metal scraps. havings Factories, causality plants destruction wastes Lumber, pipes, brick, masonry, and other construction materials from pull down buildings and other structures Demolition sites to be utilise for new buildings, replenishment projects, expressways Construction wastes junk lumber, pipe, ther construction materials current construction, remodelling Special wastes Hazardous solids and liquids explosives, pathological wastes, radioactive materials Households, hotels, hospitals, institutions, stores, industry cloaca treatment symmetricalness Solids from coarse screening and from grit domiciliate putrefactive tank sludg e cloaca treatment plants septic tanks Waste recycling and processing In the process of urbanization, the waste was once the consignment of city development as the product of urban metabolism many cities in the world have been besieged by garbage before. In now days, waste is considered to be the most potential, inexhaustibleurban mines for development it is the mislay resources.Waste all have the corresponding recycling technology, make it can be utilize as auxiliary sources into the new production cycle, so lessen resource consumption and environmental pollution. This is not only the in-depth and thick-skulled understanding of the waste, but also is the inevitable requirement of urban development. General city processed into organic compound fertilizer and apply for landscape gardening or bucolic fertilizer in organic waste processing factory. 2. prohibitionist waste (inorganic waste) further refined classified as waste paper, waste plastic, glass, scrap metal and oth er recyclable componentsin the garbage sorting centre, and then recycling plant for recyclingby thecorresponding. 3.Hazardous waste recyclable materialssent to recycling after sorting in the hazardous waste sorting disposal station and the end are safely landfill or incineration. Currently, there are several(prenominal) ways of waste disposal 1. Landfill Method Fill trash in the pit that has been ready for, make it automaticallyhappen biological, physical and chemical changes, decomposition of rganic matter, to bring home the bacon reduction and virtuous purposes but for a long time, most cities are carried out with open cast away and natural filling ditch without any protection. This leads to a lot of rubbish sewage from the surface into the ground and cause heartbreaking pollution of groundwater sources and the urban environment. Therefore this waste disposal method has gradually been eliminated. 2.Incineration method incineration method is to put thegarbage into high tempera ture furnace make one full oxidation of combustible ingredients the rage that generated can be used for force play generation and heating. The biggest shortcoming of this method is generatedof dioxin gas during the incineration thereforefor achieving environmental protection, Therefore only on the incineration of toxic and harmful gases through a series of processing,this method can realize environmental protection. 3. Composting Method dozens of garbage accumulation, heat up to 70 C, storage, fermentation, with the ability of microbic decomposition in garbage, to decompose organic matter into inorganic nutrients.After composting treatment, garbage becomes hygienic, odorless humus. Not only way to cypher the garbage, but lso to achieve the purpose of the resource but the large amount of solid waste composting, nutrient content is low, long-term use could substantially lead to soil compaction and deterioration of groundwater quality, so the scale is not easy to compost too. 4. sermon resources Careful classification of urban living garbage, Then according to the different nature of classified garbage after respectively adopt arrogate methods to deal with, make all the different types of waste can be utilized, thus to be genuinely achievereduction, harmless and resource of waste. Waste power generationFrom the 1970s onwards, some developed countries have started to use the heat generated by burning garbage to generate electricity. Some country in atomic number 63 built a garbage power plant, a U. S. garbage power plant generating capacity up to 100 MW, processing 600 thousand tons of garbage per day. Now, garbage power plant in Germany is spendinga massive sum of money from abroad to secure rubbish every year. According to statistics, currently there are nearly a thousand types of waste disposal plant all kinds of garbage utilization facility will be increased to 3000 or more in hree years. Scientists measure that the garbage in the junior-grade e nergy, such as organic fuelcontains high calorific value, the heat of burning 2 tons of wasteequivalent to about 1 tons of coal.Confrontingproblem The reason that why waste power generation is create slowly Is mainly due to the combustionpower generation, which cannot be effectively solve for a long time. Japan has been promoting a super waste power generation technology, by using new gas furnace rose the furnace temperature to vitamin D C, increase the power generation fficiency from 10% in the pastto around 25%, cut toxic emissions to less than 0. 5%, infra the international sample But, of course, the cost of waste power generation is still high than the traditional thermal power. Some experts cogitate that withthe technology development inwaste collection, handling, transport, utilization and other aspects, waste power generation is probably to become one of the most efficient power generation technologies.From the long-term benefits and the spaciotemporal index, it wil l be superior to the traditional electric power production. Conclusion In conclusion, waste is a common electrical outlet this can lead to health problems and destruction of natural resources. If people do not attach enormousness to waste classification and recycling, not only for our present life will be affected, but also for our future generations. This is not Just a country, an organization, an individuals responsibility, but the responsibility of all mankind. lf when each person throwing garbage can be a little more environmental awareness, we could effectively increase the waste statewide utilization, So that the whole society will be able to less affect by waste problems.Waste managementEach of us will throw a lot of waste every day you know where all the wastewent? Most of the waste will get sanitary landfill, incineration, composting and other sound processing in some areas with better waste management, while most places Just easy piled or landfill, this cause odour spre ad, soil and underground water get polluted. peopleare not only Just go through a lot of resources, mass production, mass consumption of land, but also produced a lot of waste this consequences will be unimaginable.This essay will demonstrate the definition of waste waste lassification, recycling, processing and some other additional materials about waste power generation. Introduction Earth is our home, which provides us with the necessary environment and space for living but with the rapid development of social economy and the urban population of highly concentrated, the output of waste is gradually increasing, our home is surrounded by garbage from day to day. In densely populated cities, waste disposal is a vexing problem.Common practice is collected and sent to landfills, or use incinerators but both would create environmental problems, and excessive onsumption can further reduce termination landfills saturation level. Improper waste disposal in landfills can contaminate groun dwater and odour, and many cities have been available for less and less landfill area.

The definition of waste Waste is also known as rubbish, trash, refuse, garbage, Junk and litter which refer to unwanted or useless solid, fluid substance. Merriam-Websterdefineswaste is the trash from places of human or animal residence The World Book Dictionary also say that waste is the useless or worthless material, stuff to be discarded. Unfortunately, these two definitions reflect a common attitude that does not admit waste as a resource.Nevertheless, Zero Waste America defines waste as a resource that is not safely recycled back into the envir onment or the marketplace. This definition onsiders the value of waste as a resource, as well as the threat of unsafe recycling wasting actually does not exist in nature, they are human inventions due to human behaviour. ln nature, everything has a purpose. Waste was created by humans for short-term convenience and short-term profit. Meanwhile, this leads to long-term harmful consequences for humans, nature, and the economy.Waste classification, recycling and processing Waste classification means according to different composition, properties, use value of waste as well as the impact on the environment, andthe requirements of different isposal methods, divided into a number of different types of properties. lts purpose is to bring convenience for resource recovery and subsequent disposal. The meaning of the classification of waste People are faced with the situation of the growing waste production and environmental deterioration.How to through the waste classification managementto maximize waste resource utilization, reduce the amount of garbage disposaland improve the living quality of the environment is currently the worlds pressing problems of common concern. Waste classification is the reform of the traditional ay to garbage collection disposed it is aneffectivescientific management methodfor waste disposal. Waste classification is put waste classificationat source, and through the classification of the pickup and recycled back into a resource. The benefit of waste classification is obvious.After being classification, waste was sent to a factory instead of landfills, not only save the land, but also avoids the pollution produced by landfill or burned. Waste classification Recyclable waste They are mainly five categories which include waste paper, plastic, glass, metal, and cloth. Waste Paper mainly includes newspapers, periodicals, books, all kinds of wrapping paper and so on But should pay attention to paper towels and toilet paper because of their water soluble is too strong, cannot be recycled. Plastic plastic waste containers, plastic packaging and other plastic products.Such as various plastic bags, plastic bottles, foam, disposable plastic lunch boxes cutlery, hard plastic and so on. Glass mainly includes all kinds of glass bottles, pieces of broken glass, mirror, light bulb debris, and thermos bottle, etc. Metal mainly includes cans, cans and so on. Fabric mainly includes the abandoned clothes, tablecloths, towels, bags, shoes and so on. Kitchen waste Kitchen waste is refers to catering units, enterprises, institutions, schools, canteens and other food scrapswaste, unremarkably known as swillor pigwash.The main component of kitchen waste are starch, food fibre, animal fats and other organic substances it have a high moisture content, fat, high salt content, perishable smelly fermentation characteristics. Hazardous waste Toxic and hazardous waste refers to the solids that could be harmful to human body ealth or toxic substanc es or cause real harm to the environment or potential hazards wastes. Including batteries, fluorescent tubes, light bulbs, mercury thermometers, paint bucket, home appliances, expired drugs, expired cosmetics.If the battery is burned, after the blast will be killing hundreds of people Fluorescent tubes and bulbs are Just like the battery, radiation is also large Mercury is more landfilling. Other rubbish Includingin addition to the above-mentioned categoriesgarbage, such as ceramictile, muck, toilet waste paper, paper towels and other difficult to recycle waste, usually ased on the characteristics and take the way of burning or burying garbage processing. Waste materials by kind, composition and sources.Kind Composition Sources Garbage Wastes from preparation, cooking, and serving of food market wastes wastes from handling, storage, and sale of produce Households, restaurants, institutions, stores, markets Rubbish Flammable paper, cartons, boxes, barrels, wood, tree branches, yard t rimmings, wood furniture, bedding, dunnage Inflammable metals, tin cans, metal furniture, dirt, glass, crockery, minerals Ashes Residue from fires used for cooking and heating and from on-site burningStreet refuse Sweepings, dirt, leaves, catch basin dirt, contents of litter receptacles Streets, sidewalks, alleys, vacant lots Dead animals Cats, dogs, horses, cows Abandoned vehicles Unwanted cars and trucks left on public property Industrial wastes Food-processing wastes, boiler house cinders, lumber scraps, metal scraps. havings Factories, power plants Demolition wastes Lumber, pipes, brick, masonry, and other construction materials from razed buildings and other structures Demolition sites to be used for new buildings, renewing projects, expressways Construction wastes Scrap lumber, pipe, ther construction materials New construction, remodelling Special wastes Hazardous solids and liquids explosives, pathological wastes, radioactive materials Households, hotels, hospitals, institu tions, stores, industry Sewage treatment correspondence Solids from coarse screening and from grit chambers septic tank sludge Sewage treatment plants septic tanks Waste recycling and processing In the process of urbanization, the waste was once the burden of city development as the product of urban metabolism many cities in the world have been besieged by garbage before. In now days, waste is considered to be the most potential, inexhaustibleurban mines for development it is the misplaced resources.Waste all have the corresponding recycling technology, make it can be used as secondary sources into the new production cycle, thus reducing resource consumption and environmental pollution. This is not only the in-depth and deep understanding of the waste, but also is the inevitable requirement of urban development. General city processed into organic compound fertilizer and used for landscaping or agricultural fertilizer in organic waste processing factory. 2. Dry waste (inorganic was te) further refined classified as waste paper, waste plastic, glass, scrap metal and other recyclable componentsin the garbage sorting centre, and then recycling plant for recyclingby thecorresponding. 3.Hazardous waste recyclable materialssent to recycling after sorting in the hazardous waste sorting disposal station and the residue are safely landfill or incineration. Currently, there are several ways of waste disposal 1. Landfill Method Fill trash in the pit that has been ready for, make it automaticallyhappen biological, physical and chemical changes, decomposition of rganic matter, to achieve reduction and harmless purposes but for a long time, most cities are carried out with open dumps and natural filling ditch without any protection. This leads to a lot of rubbish sewage from the surface into the ground and cause serious pollution of groundwater sources and the urban environment. Therefore this waste disposal method has gradually been eliminated. 2.Incineration method incine ration method is to put thegarbage into high temperature furnace make one full oxidation of combustible ingredients the heat that generated can be used for power generation and heating. The biggest shortcoming of this method is generatedof dioxin gas during the incineration thereforefor achieving environmental protection, Therefore only on the incineration of toxic and harmful gases through a series of processing,this method can realize environmental protection. 3. Composting Method piles of garbage accumulation, heat up to 70 C, storage, fermentation, with the ability of microbial decomposition in garbage, to decompose organic matter into inorganic nutrients.After composting treatment, garbage becomes hygienic, odourless humus. Not only way to solve the garbage, but lso to achieve the purpose of the resource but the large amount of solid waste composting, nutrient content is low, long-term use could easily lead to soil compaction and deterioration of groundwater quality, so the sca le is not easy to compost too. 4. Treatment resources Careful classification of urban living garbage, Then according to the different nature of classified garbage after respectively adopt appropriate methods to deal with, make all the different types of waste can be utilized, thus to be truly achievereduction, harmless and resource of waste. Waste power generationFrom the 1970s onwards, some developed countries have started to use the heat generated by burning garbage to generate electricity. Some country in Europe built a garbage power plant, a U. S. garbage power plant generating capacity up to 100 MW, processing 600 thousand tons of garbage per day. Now, garbage power plant in Germany is spendinga huge sum of money from abroad to buy rubbish every year. According to statistics, currently there are nearly a thousand types of waste disposal plant all kinds of garbage utilization facility will be increased to 3000 or more in hree years. Scientists measure that the garbage in the sec ondary energy, such as organic fuelcontains high calorific value, the heat of burning 2 tons of wasteequivalent to about 1 tons of coal.Confrontingproblem The reason that why waste power generation is developing slowly Is mainly due to the combustionpower generation, which cannot be effectively solve for a long time. Japan has been promoting a super waste power generation technology, by using new gas furnace rose the furnace temperature to 500 C, increase the power generation fficiency from 10% in the pastto around 25%, reduced toxic emissions to less than 0. 5%, below the international standard But, of course, the cost of waste power generation is still higher than the traditional thermal power. Some experts believe that withthe technology development inwaste collection, handling, transport, utilization and other aspects, waste power generation is likely to become one of the most economical power generation technologies.From the long-term benefits and the comprehensive index, it wi ll be superior to the traditional electric power production. Conclusion In conclusion, waste is a common issue this can lead to health problems and destruction of natural resources. If people do not attach importance to waste classification and recycling, not only for our present life will be affected, but also for our future generations. This is not Just a country, an organization, an individuals responsibility, but the responsibility of all mankind. lf when each person throwing garbage can be a little more environmental awareness, we could effectively increase the waste comprehensive utilization, So that the whole society will be able to less affect by waste problems.
