Solid waste management is a challenge for the cities authorities in developing countries mainly due to the increasing generation of waste, the burden posed on the municipal budget as a result of the high costs associated to its management, the lack of understanding over a diversity of factors that affect the different stages of waste management and linkages necessary to enable the entire handling system functioning. Bhubaneswar is one such city of Eastern India, having a moderate and unscientific waste management system. This studies attempts to assess the existing state of municipal solid waste management in Bhubaneswar city with the aim of identifying the main obstacles to its efficiency and the prospects for improvisation of the solid waste management system in the city. The existing solid waste management system in the city is found to be inefficient. This paper systematically assesses the obstacles in the existing solid waste management system in city also ties to assess the potential for its improvisation.
With rapid population growth and urbanization, annual waste generation is expected to increase by 70% from 2016 levels to 3.40 billions tones in 2050. Compared to those in developed nations, residents in to those in developed nations, residents in developing countries, especially the urban poor, are more severely impacted by unsustainable managed waste. Waste is defined as unwanted and unusable materials and is regarded as a substance which is of no use. It may no longer useful as it has served its purpose, and at the end of the process have no further use, and is generally discarded. It is often also called trash, garbage, rubbish or junk. It can be solid, liquid or gas, or it can be waste heat.
II. EXPERIMENT DETAILS
We visited two dumping yards to know the waste management and disposal process of Bhubaneswar.
Sainik School dumping yard
Bhuasuni dumping yard
The dry waste and wet waste are separated manually by the BMC employees.
2. After separation of dry and wet waste the wet waste is decomposed for 30 days.
3. And after 30 days this is the result.
4. After 30 days of decompose the waste is left to dry for 14 days to become fertilizer.
5. The fertilizers are again poured on the machine to separate the left over tiny pieces of plastic so that the fertilizer is now ready to be sell on the market.
6. This is the final fertilizer bag “MO KHATA” which is packed and ready to be sell in the market.
B. Dry Waste
All the wet waste collected are mixed on this machine.
From here again it will be separated accordingly.
2. Shredding Machine
The dry waste is now poured in the machine to make it into small pieces so that it can be used for further use.
3. Fatka Machine
All the dry waste contains small drops of water which are made to dry here.
After drying the plastic bottles and the paper cardboards are made to be compress that they occupy less space.
IV. RESULT AND DISCUSSION
At last we got shredded materials of different plastic waste and compressed plastic.
We got well prepared fertilizers from wet waste
The waste management system of Bhubaneswar is not so advanced as compared to other cities of India. Bhubaneswar has a moderate and unscientific waste management system.. The whole management process of completely based on government guidelines.
Government now has to work a lot on the waste management process.
