uses of swachh bharat in scientific way

Answer 1

We can certainly use technology effectively to improve swatch bharath scheme and make it a great success as follows.

The disposal of solid and liquid waste generated by 1.3 billion Indians is challenging not only for the politicians who are taking all the brickbats as of now but also to scientists. It is estimated that each individual produces approximately 2.25 Kgs. of solid waste a day which comes to 3 billion Kgs (approx) of solid waste every day in India. If land filling method alone is used I am sure the whole of India will turn out to be a great garbage bin. Technology need to be used effectively to utilize it in such a way to benefit the citizens. It is estimated by experts and scientists that 70% of solid waste can be reused. The following are some methods that can be thought of.
The tracking devises RFID can be installed for pick up and disposal of wastes in the trucks with electronic record of the truck route along with a time stamp and geospatial stamp. With this it is possible to calculate the number of participants in the programme, the number of plastic reusable bins available in the truck, non reusable bins available in the bins etc. It will be easy to plan how to dispose of the same effectively in advance.
Pay as you throw can be implemented by charging nominal fee of say Rs 5 per Kg. of garbage. The household will try to minimize the waste which certainly help the authrities. In middle class locality and higher end households do not mind paying this amount. It may also lead to throwing the garbage in nearby open localities unseen by any person. It will lead to health hazards.
Waste to electricity, ethonol or cooking gas are being tried successfully in many countries including in India. In Bangalore the BBMP has been using the wet waste to produce manure for use to plants. Also are segregating the wet and solid wastes at the level of each households. The solid wastes are sent for reuse. Wet waste is converted as manure. This requires further refining and planning, which will take place as the authorities gain experience.
The Bio - Toilets of Railways is another method of disposal of wet wastes.
Plastics and other reusable solid wastes are sent to reusable plants.
POTABLE WATER is another immediate need of the vast majority of people who have not been covered under the scheme. Most of the cities and towns are covered under potable water scheme. The villages are the ones who are affected. This needs urgent attention
The sewage water is now let off into agricultural fields. These water produce toxic materials which are harmful to human consumption. Hence the sewage water should be scientifically treated before letting off into the fields. Technology provides for the reuse of these water. In Singapore it is effectively reused. In Delhi an attempt has been made for sewage water to be treated and reused.
Minimising of Pollution by using technologies such solar power for electrification, electric motor vehicles, etc. Use of bio-fuels for various uses in households, transport etc...
