Mandur Landfills Essay

Case study: Mandur landfills

Mandur is a sub-urban village in the vicinity of Bangalore. Once a sleepy village surrounded by mango orchards, grapevines and fields of ragi and jowar. Is now a victim of multistory apartments with the relentless expansion of Bengaluru city, which is rapidly overrunning Mandur’s landscape.
Mandur, now known for it garbage landfills. The dumping of municipal waste is the direct effect of rapid urbanization and poorly planned construction. The landfills in mandur are located at about 500 meter’s from mandurs Main Square. The nauseating smell of the decomposing and rotten waste surrounds the entire village. According to the official reports about 700 heavy-duty trucks dump garbage in the landfill every day.

In mid June, the villagers blocked to incoming of the garbage filled trucks from entering the village. This caused a major block in the state high way and finally attracted attention of the Chief Minister of the State.
The protest was stopped after the intervention of the current CM of Karnataka, Mr.Siddaramaiah promised that the dumping will stop in 5 months and the landfill will be cleared with in three year.
According to experts in waste management, the problem can find a lasting solution only if biodegradable waste is segregated from non-biodegradable waste at the source. “In the past two years, many progressive changes have taken place in the way Bengaluru manages its waste. It is the first city in India where segregation of municipal waste at source has become mandatory,” says Sashikala Iyer, a researcher with the Bengaluru-based civil society organisation, Environment Support Group (ESG). “That was an outcome of the directions issued by the Karnataka High Court in response to a number of public interest petitions, including one by ESG, regarding the poor state of solid waste management and its adverse impacts. The court stressed upon the need for public involvement and decentralised efforts in tackling the prevailing garbage crisis. The change has even influenced the way waste is managed in
In first world countries, advanced waste management techniques are on the rise. This has given rise to the forth R, which is Recover. Advanced Thermal Treatment(ATT) is most recent techniques used for waste management followed in America, Germany, Europe and Japan.
Advanced Thermal Treatment(ATT)
Advanced Thermal Treatment technologies are primarily those that employ pyrolysis and gasification to process municipal solid waste (MSW).
The gasification and pyrolysis of solid materials is not a recent concept. It has been used extensively to produce fuels such as charcoal, coke. Pyrolysis of coal and wood gives coke and charcoal respectively and in addition a combustible gas in produced by gasification of coke in the presence of controlled quantity of oxygen. Post 2006 pyrolysis and gasification have been commercially used in treatment of Municipal waste. Large-scale ATT plants are functioning in Japan, Europe and North America.
ATT includes two main processes
1. Pyrolysis
2. Gasification

ATT-Pyrolysis:
Pyrolysis is the thermal degradation of a substance in the absence of oxygen. Raw municipal waste is not appropriate for this process and segregation is highly
