We have been to some of the cleanest cities across the country and have rated them. The system for rating cities was to determine who is the cleanest of them all in terms of solid waste management. It is clear that cities that are segregating their waste have been able to effectively process and treat it and have achieved the status of zero landfill cities. While, some cities are doing – part segregation and part treatment. And then, there are a few cities, that are visibly clean but dumping their waste. We have incorporated all our findings in our book.
