SOLID WASTE MANAGEMENT

Solid-waste management, is the collecting, treating, and disposing of solid material that is discarded because it has served its purpose or is no longer useful with application of various techniques to ensure orderly execution. Solid waste disposal and management is an urban problem. Every person is a potential generator of waste and thus a contributor to this problem. Waste generation therefore tends to increases with an increase in population and economic growth. Generally it has been observed that the waste that is generated is more than the capacity for it to be managed. Waste and rubbish can cause water and air pollution and so the current practices that are being carried out are proving out to be unsanitary and less productive. Therefore the most important reason for collection of this waste is the protection of the health of the population and the environment.

There are about eight different types of waste, out of which five like the bio-medical waste, the dead animal waste, E-waste, construction waste and hotel waste, are looked into at the city level and three household waste, waste on roads and that found in commercial bins are looked into at the ward level. The above mentioned process of solid waste management system is also being followed in Ahmedabad. It works in two ways where one is the waste generation from the households and commercials is b

There are various types of households like the chawls, bungalows and societies from the waste are collected in the segregated form. In the societies the wet and dry waste generated from each of the households is first collected by assigned worker from the society who collects the segregated dry and wet waste and then empties it in to barrels which are placed outside the society entrance gate in a segregated manner as collected, to be further collected by the chota haathi. The barrels bins were p

To ensure efficient segregation the source segregation needs to be dealt with first. For this the AMC would issue a notice to all the societies stating that all the societies would have to start following the segregation and collection and storage rules addressed to them. Three bin concept to be introduced where the waste needs to be collected in three different streams wet, dry, and domestic hazardous waste by the appointed worker of the society who would also ensure segregation by making sure

There is a lane to lane or point to point collection method of collection which is being used for the collection of waste from the slums and chawls. The waste is collected from a common area where people come and empty the segregated waste into the two coloured chota haathi. These collection points are considered as point of interests (POIs) which are then monitored in the Eco-skipper.

The same model as that of the societies would be replicated here by involving the SHG (Self Help Group) workers. Instead of lane to lane a new concept of door to door collection of waste for the slums could be introduced. AMC would identify the area of a particular slum and chawl. Then demarcate the areas with approximately 60 households in each of them. 2 demarcated areas would be assigned to one Self Help Group worker. After which the total number of SHG workers should be taken into account.

These RFID tags need to be placed on the bins for more accountability of the waste collection in the monitoring process. Low frequency RFID tags of less than 1 m range are placed on each bin and on top of each vehicle which would make it would be easy to ensure which type of waste has actually been collected from the concerned society on that particular day and time. This would also let supervisor know whether the bin has been served or no or missed also number of times each society has been s

All the waste that is segregated and collected from the households’ commercial buildings and by the road sweepers is taken to the RTS- refuse Transfer Station for further processing.

The dry waste that is collected from the door to door collection is emptied at MRF for further segregation into various categories, after being weighed.

The waste which is transferred to RTS has few issues which need to be delt with for better functioning of it as improper infrastructure would mean reduced efficiency in waste segregation.

Waste needs to be dumped into sections surrounded by curb wall of height 150mm with sufficient space left on either side of the sections so that women can easily segregate the dry waste faster and in an efficient manner this would also reduce the risk of health issues faced by them. It will help in keeping the cattle away from feeding n waste as they would not have to walk on the waste anymore.
