 So, whatever principles that we discussed decentralization reduction of solid waste at the source itself segregation all these have been put under one conceptual framework which is known as integrated solid waste management. This is recently being introduced it was there from the beginning itself, but it was recently given a name under CPH EO manual 2016 and under solid waste management rules 2016. So, the basic principle is again minimum amount of waste should go to the landfill. It is an inverted pyramid sort of a framework. You have to segregate reduce recycle at as much as possible before you are releasing everything into the landfill. So, this is an integrated solid waste management framework. Under this again as I said that you have to add source minimization you have to do. One thing which I want to draw your attention is extended producer responsibility through brand auditing. Are you aware this term extended the producer responsibility? Extended producer responsibility is the extended what we call responsibility given to the producer like just like what an example of clip card only they are using a lot of material. So, I would say like they are engaging it, but there should be a responsibility of these people that what happens to this packaging material waste. So, if they are managing it then they are adding to their extended producer responsibility. So, was it clear? So, it is like when you buy something like for example, a packet of lanes ok you pay for the product you do not pay for the wrapping or the rapport. So, that is what they say and what are these are the claims of people who ever you know propose this phenomenon this concept. So, what they do is that you want the producer to take the responsibility of managing this waste and how do you do that? So, for that there is one exercise which was done in different parts of India for different cities which is called brand auditing. So, we tried this thing in Kerala. So, what we did is that we have aerobic bins ok. And there are plastic and other kind of waste is being deposited by the household. So, what we do is that we sort waste according to the brands like how many packets of lays are being or chips are being you know from a particular brand. So, lays or other kind of uncle chips and different kind of thing and how many packets of waste are from local producers or international brands. And then we weigh them and then we find the weight of that and then accordingly we can we want to tell the producer that you are you are producing this much waste you should be taking responsibility of that. So, that is what is known as brand auditing ok. So, this is a report that was released on 5th of June this environment day you can find it on internet actually. And there are other things that you can do to reduce you know usage of such kind of material. Segregation I have spoken about before. So, there is a three bin system for wet dry and domestic hazardous waste which is collected in black container. I think most of the bigger cities have started to adopt this particular model of segregation. Collection and transportation. So, there are two kind of collections can happen one is primary and another is secondary. Primary is directly from the household or the or the producer and secondary which is from the community bins, waste storage depots, transfer stations like in Hallaby you have secondary system of collection. So, households have to deposit their waste in a community bin or aerobic bin and from there the municipality takes care of the waste. And in other cities you might find that collection is happening at the household level. So, these are the two basic types of collection systems that the cities can adopt. So, primary type can work for the small larger towns and this might can work in all the cities that is needed. Recycling I do not have to tell you what are the benefits of recycling right. Material recovery. So, this is the thing that we were talking about how do you recover different types of material. Ok, I am going to talk about this is the material recovery facility which is in Trivandrum for plastic waste. Ok, so what they do is that all the plastic waste comes to this particular facility and what they do is that whatever is the recyclable plastic is shredded and is then sell at 20 INR per kg to the to making for making the roads to mix it with vitamin. So, this is MRF facility for the plastic waste similar kind of MRF facility you can have for other kind of waste like batteries, aluminium and all kind of things you can have. Since for treating and utilizing different kind of municipal solid waste management. Ok, biodegradable waste can be managed through composting everybody knows what is composting right and then there is another process called biomethanation through which biogas is reduced and you can use it for cooking and heating purposes and other kind of purposes. Combustion is another process which is used for non-biodegradable waste. In India there are three methods for that gasification, incineration and pyrolysis. In India incineration is most famous although two are still being tried and tested there is no proven technology that kind of fits Indian condition because India is quite humid in that sense. So, you need to maintain certain kind of temperature that is one thing and the second thing is that for these two methods gasification and pyrolysis you need to have a well sorted waste which is not possible in Indian cities. No matter how much you segregate there will be issues. Ok, need to explain to you what is composting? Sure? Yes. Oh great, my work is reduced. So, we have four different type of composting technologies. I am not going to explain to you or do you want me to explain? I can show you the graphs. So, I am not for graphs, photographs. So, this is windrow composting. I think one of the participants mentioned that they have windrow. So, yeah. So, can you explain little bit more about it? Just shortly. Windrow basically they will have yards that may be covered. It is covered in my case. They have sheds and they will segregated organic waste is layered with cow dung or other organic material which is collected from the place and they will there is a cycle. So, they will activate the compost with some inputs or other make compost and other things and then they will like 45 days they will turn the waste. So, after this is complete they will see it for other solid matter or something and then they will directly apply wherever needed. So, which city are you talking about? No, I am talking about town panchayat in Coimbatore. So, are there any other examples in your city which you are like using what we composting? This is the bin composting that we have in Trivandrum and it is there in Ellipi also. And this is the pipe composting which is meant for households. So, this is pipe composting I was talking about pipe composting is it was tried in Ellipi in the city which is suitable for household level because in Ellipi as I said that they do not have much of land available. So, they wanted to process the biodegradable waste whatever the constraints of land were there. So, this was the pipe composting that they tried and Sriritha is going to talk about that if it succeeded or failed in help in this context. This is summary of compost technology. It actually talks about what should be the scale where you can you know employ different kind of technology like windrow and in vessel could be large scale where you have to deal with large scale biodegradable waste. And what we composting is obviously small but what we composting is very temperature sensitive you know technology and you need experts for that. So, these are the different methods and appropriate links of different methods for that.
