Waste management in India Essay

Waste wariness in India EssayINTRODUCTIONIndia is the second around d head country a second fastest growing thrift in the world. From the period of 2001-2026 the community of India is to annex from 1030 million to 1400 million, if we consider the amplification regularise to be 1.2 % annually then in that respect will be an make up of 36% in 2026.accordingly advantageouslyspring-nigh 285 million live in urban countrys and about 742 million live in rural beas. ( number of India, 2001).In India urbanization is becoming more because peck ar moving from villages to cities and thither is a rapid growing in nation in the metropolitan cities .Mumbai is the largest populated city followed by New Delhi and Kolkata.Generally, the greater the stinting prosperity and the high the percentage of urban state, the greater is the amount of potent drive off make growd (Hoornweg and Laura, 1999). In Hoornweg and Laura, 1999 1996 about 114,576 tonnes/ twenty-four hour period of mu nicipal loyal decompose was gene identifyd by the urban people of India, by the end of 2026 it is predicted to increase to 440,460tonnes/day This great increase in the amount of MSW generated is due to changing lifestyle and living standards urban population(Hoornweg and Laura, 1999).STUDY AREADelhi is a very densely populated atomic number 18a and is the capital of India. Since Delhi is an urbanised city the annual growth rate is change magnitude very rapidly in the last decade the growth rate has increased by 3.85%. Delhi is the capital of India this tells us that it is the centre for commerce make do and power, since it is one of the largest cities and the capital it produces excellent job opportunities, which account for its rapid increase in its population and increased pace of urbanization. Due to the fast urbanisation and the growing population the production of municipal substantialness nullify is in every case increasing very rapidly. According to a survey Delhi ge nerates about 7000 tonnes/day of municipal unbendable intemperance and this municipal excess is to ride about 17000-2 cholecalciferol0 tonnes/day by the year 2026.due to the rapid increase in the population and municipal solid furious the government of the drive off has become a great head ache for the municipality in Delhi. Out of the uncivilized gathered only 70-80% of municipal solid angry is collected while the remain is dumped onto streets or open ditches. Out of the 70-805 collected only 9% of the collected municipal solid waste is treated by composting the remaining is send to the land fill sites. New Delhi municipal great deal (NDMC), The Municipal bow window of Delhi (MCD) and Delhi Cantonment Board (DCB) ar three municipal entities responsible for MSW management in Delhi. (Vikash Talyan, R.P. Dahiya, 2008).IDENTIFICATION OF SOURCES, TYPES AND COMPOSITION OF MUNCIPAL SOLID WASTE IN DELHI originations and types of solid waste in Delhiresidential-the residence mi ght be atomic number 53 family or multiple family d headers the types of waste they produce are paper, food wastes , cardboard , leather, yard wastes, textiles, glass, special wastes, metals, plastics , ashes, wood and household hazardous wastes.Industrial industries produce ashes, food wastes, packaging, special wastes, housekeeping wastes, construction and demolition materials and hazardous wastes. commercialisedized Institutional they produce wood, metals, cardboard, glass, special wastes, Paper, food wastes, hazardous wastes.Municipal service landscape and tree trimmings, Street sweepings, general wastes from beaches, parks, and other recreational areas, sludge. (Hoornweg, Daniel with Laura Thomas. 1999) formation of wasteThe population of Delhi is 13.9 million, and they produce 7000 tonnes/day of municipal solid waste at the rate of 0.500 kg/capital/day and accordingly the population as well as the MSW in increasing by 2026 the municipal solid waste generated will increa se to 17,000-25,000 tonnes/day. Because of the increase in the MSW the municipal body will face a lot of problem later on composting and incineration they would still have to deal with a lot of waste and this waste would generally go to landfill sites.The characterisation of the waste by its type, organization and address is important this will make monitoring and management of solid waste easy. Based on this we hind end use different types of processes to dispose the solid waste.

There was a survey conducted by Municipal Corporation of Delhi to evaluate the composition and appropriateties of M SW. This study involved the different places in Delhi where MSW was produces.

(Ministry of Environment and Forests, 2000)MUNICIPAL SOLID WASTE MANAGENENT IN DELHIPrimary collection and entrepot of MSW in DelhiAccording to the Delhi municipal corporation act 1957 the owners, te nants or the person who is occupying the residence, commercial or industrial area is responsible for the disposal of the MSW at a finical area provided by the municipal corporation. But this rule was changed in 2000 which stated that the collection of MSW would be from house to house because of this rule the municipality cooperation face a lot of problem due to the rise in population as well as residential houses so doth the systems are be applied to collect MSW. The municipal cooperation of Delhi is getting awareness programs to answer the citizens register the need of segregating the municipal solid waste by placing two affiliate bins one for recycling materials and the other non-recycling materials. By doing this the municipality is reducing the work institutionalise and they can dispose of the material in an easy way without any fuss. The municipal authority has a schedule for the collection of the waste eccentric a particular area will have a particular day for the coll ection of MSW.The Delhi municipal authority provides a primary storage facilities like dustbins, metal containers that have different capacities ranging from 1m3 ,4m3,10m3 to 12-15 tonnes these containers are placed in locations that are easily accusable to people. The size of the containers that are place at a primary storage location depends on the amount of MSW being produced by the area and the population of the area. These metal containers and bins are emptied with the suffice of modern hydraulic collection trucks. In Delhi on an average there are 3-4 collection sites. The MCD has employed about 50,000 people for primary storage collection, 2600 for secondary storage collection and about 370 people foe sweeping the streets. (Ministry of Environment and Forests, 2000) conveyancingThe MCD has many vehicles for the collection of primary and secondary storage waste. The MSD in its authorize contains refuse removal trucks, tractors and loaders they have about 100 vehicles to do th e job. What these vehicles do is they collect the waste and take them to the landfill sites.Recycling and re-useRecycling and re-use of MSW is done in a widespread manner where waste pickers are employed as well as there are self employed waste pickers who collect the waste and sell them. How the system works is that these waste pickers and waste collectors gather waste from the residential areas, commercial areas, streets and landfill sites and they sell them to the dealers these dealers range from small, speciality and large dealers. After the dealers purchase the materials they are sent to the recycling graft that is established by the government. The following table tells us at what rate the materials are sold (Ankit agarwal, Ashish Singhmar, 2004) wrongs of useful materials at different recycling levelsRecyclable materialRecyclable material Price at smallrecyclable dealer (Rs.)Price at mediumrecyclable dealer (Rs.)Price at largerecyclable dealer (Rs.)Value added in the appen dage (%)PlasticPET bottles1.752.25-2.503.75-4121Milk packets5.5-6.56-78-8.5037.5Hard plastic like shampoo bottles, caps7-7.25910-10.541Plastic thread, fibres, ropes, chair cane6-78-8.501067Plastic cups and glasses7-810-1213-1480PaperWhite paper3-3.253.75-45-676Mix shredded paper2-2.252.25-2.503-3.2547Cartons and brown packing text file2.252.50333Fresh newspaper3-3.503.25-3.754.50-4.7542Tetra pack1.75-22-2.252.75-353GlassBroken glass0.500.90-190Bottles22.25-2.5019 atomic number 13Beer and cold drink cans40-4543-4875-8588Deodorant, scent cans42-4555-6090-95113Aluminium foil20-2225-2730-3248Other metalsSteel utensils20-2225-273043Copper wire70-7580-8595-10035Source Ankit agarwal, Ashish Singhmar, 2004)CompostingComing to composting only 9% of the total MSW is composted the remaining 91% is sent to landfill sites. There are three places set up by the Delhi municipal authority for composting MSW where as two vegetations are set up at Okhala and the other one is set up at Bhalswa .Thes e plant has a treatment capacity of 150 tonnes/day but they are not utilised to the fullest because of the cost. The treatment capacity of the plant at Bhalswa is 500 tonnes/day. (Vikash Talyan, R.P. Dahiya, 2008)IncinerationThe municipal cooperation of Delhi as well tried incarnation they built an incineration plant with the help of a foreign company. But this was shut down immediately because the MSW did not have enough calorific value the minimum calorific value is between 1200-1400 kcal/kg. (Vikash Talyan, R.P. Dahiya, 2008).Final disposal of MSWOf the total amount of MSW collected 91% is sent to landfill. These landfill sites are located at the outskirts of the city. The land fill sites are the nearest available low line area or waste lands. The transfer of the MSW to these sites is by the vehicles that the Delhi municipality has. These landfill sites are chosen based only on availability and not on any other reason. These landfill sites are ailing maintained which arises a p roblem of health and sanctuary as well as environmental concerns. There is another big issue because of the low maintenance of the landfill sites there is a lot of leachate that is being produced mostly in the rainy season due to which the ground water as well as the river next to the landfill sites is getting contaminated. At these landfill sites with the help of bulldozers the MSW is levelled and compressed. The MSW is compressed to a layer of 2-5m and a covering is provided. At the binging there were 20 landfill sites that were created by the Delhi municipality out of which 15 are exhausted already. At present there are 3 landfill sites that are being operated one is at Gazipur it was started in 1984 , the other landfill site is located at Bhalswa it was started in 1993 ,the last operating(a) land fill site is located in Okhala it was started in 1994. (Vikash Talyan, R.P. Dahiya, 2008). health AND SAFETY AND ENVIRONMENTAL RISKSHealth and safety and environmental risks are a maj or concern in the MSW management in Delhi. The workers as well as the waste pickers are not provided with proper health and safety equipment like boots and gloves. The working conditions are unhygienic .the chance of transfer of transmittance is high and because of this if a worker gets sick he loses his wages. The workers are also not provided with medical insurance. The environmental risk is also high because the landfill sites are not maintained properly and the leachate gets leaked into the underground water as well as the river Yamuna .these issues should be looked into very carefully.IMPROVEMENTWe can improve these brusque conditions by privatisation. We can let the private sectors help in the disposal of MSW. The Delhi municipal authorities can open the incineration plant and dispose the waste. They can also involve the local communities as well as the NGOs to help in the disposal of waste. The municipal authorities should identify a proper treatment technology. The authori ties should increase standards of reuse and recycling of waste in the main composting.CONCLUSIONWith the rapid increase in population and fast urbanisation of Delhi the current policies and regulations want be sufficient for controlling the rapid increase in the MSW. Due to this the health and safety as well as the environmental risks are increasing .The municipal authorities of Delhi cannot keep up with the MSW that is being produced now but according to a prediction the MSW by 2026 is going to increase 4 folds if this happens the municipal authorities will be facing a lot of problem. Even the Delhi government has realised this and they are making changes in the form of master plans. The government is also access the public and private sectors for help like the citizens and the NGOs. First of all people should be educated on proper disposal of MSW. The government should charm to that the master plans are being properly followed at all levels. completely by doing this the Delhi municipal authorities can keep the MSW in control.ReferencingAnkit agarwal, Ashish Singhmar, 2004.
