 of plastic waste management, as I said that plastic can be segregated for the brand auditing we did that, recyclable and non-cyclable, recyclable waste. So, these are the different categories of plastic which you can you know recycle and use, but one thing one needs to be reminded of is that plastic cannot be recycled indefinitely. So, once is there in the, once there in the system it will remain. It is very difficult to you know do anything about it, once is there in the system. These are the different options for plastic waste management. I have already spoken about this thing the planting with the bitumen and the other thing is that incineration if you want to dispose of. Plasma fireplaces is happening, but I think there are only 2 or 3 plants all over India that to an industrial level. It is not happening at the city level. This is very, very expensive technology and most of the urban local bodies they cannot afford to have, neither they have the capacity and nor they have the skills or the money first of all. Paper waste management you know how it done right, execution, initial sorting and this is the process of making handling paper ok. Waste to energy I have already spoken about little bit the biomechanation part and the most preferred part in most preferred technology in Indian case is incineration or biomechanation ok. But, Gerard if you see we have about 8 systems all across all across India in Andhra Pradesh to Maharashtra to when these this is the different kind of waste to energy systems all across India. These are the challenges as I said all waste to energy systems the most biggest challenges to provide sorted waste which is very difficult in Indian cities. You cannot provide sorted waste in the required waste and obviously there are environmental impacts of these waste to energy if you are not employing any air pollution method and obviously these are very expensive again ok. So, sanitary land we discuss about the landfills actually most of the cities are not landfills those are dumping sites. So, there is a difference between landfills and the dumping site. So, these sanitary landfills means where the final and same disposal of residual solid waste. It is not as I said before it is not, but then ultimately there will be certain materials which you cannot process or reuse you have to ultimately dispose. So, yeah. There are items in that particular item which we cannot dispose of. So, what is the solution? There is no solution you have to dispose of that is that is the only thing you can do. As I said that plastic you can even if you you know convert it into and use it as a mixture with between ultimately plastic is there floods will come roads will go away plastic will remain ok. So, there are certain things which you cannot do away with it. You have to dispose it in some maybe more controlled manner if not like openly you are throwing them away it is like more controlled approach to disposal and management. So, sanitary landfills I do not think so we have any example in India of sanitary landfills correct me if I am wrong and these are the things sanitary landfills have to take care of. They have to take care of pollution of groundwater, surface water, any air dust, a bad order of fire hazard, animal menace, GHE's and persistent organic pollutant slopes instability and inorganic erosion. Sanitary landfills are necessary for any non biodegradable and inert waste mixed waste not found suitable for waste processing. So, these are the things that should go ultimately to landfills and these are the things that are not allowed to go to sanitary landfills. Obviously, biodegradable waste should be preferably composted, dry or recyclable and hazardous waste should be managed. This is a typical diagram which is the recent CPH EO manual also came out with and the solid waste management rules. So, these this is the sanitary landfill how it looks like it has a layer so that leeches will not go it has a you know system here piping system. So, that leeches will be drained out in a controlled manner. So, these are the different component of sanitary landfill. So, before she starts the next session. So, we spoken about integrated solid waste management planning which is multiple interventions at each step of the waste team. So, segregation, collection, transportation, disposal it involves integration of multiple stakeholders. So, informal sector is not outside the relieve of government or the value chain. It has to be incorporated within the formal chain. It aims to reduce total volume of the waste that is reaching to the landfill. It optimizes resources and material recovery. So, these are the few principle of integrated solid waste management, but is it possible can we do that? So, LAP as I mentioned that LAP experimented with the decentralized waste water management. It experimented with no bin policy. So, she is going to talk about this efficacy of such kind of a model for small towns like LAP. Okay.
