  2. 2. Currently what is happening in our cities? “ Mostly resources are mixed and this is collected
  3. 3. We have no space allocated in our urban design. THIS IS CRITICAL. No body wants waste trucks parked outside their homes, but they need to be parked - so where? Cities have to allocate space for transfer points, segregation points, collection centers, processing, debris management, parking and landfills. Without space, we will continue with our mindsets biased to wasteful centralised systems. Equipment & Technology We have a love affair with "Large Projects". We feel we must change this bias to "Large number of small projects". We have to make the right choices on equipment and technology, not forgetting, downtime, maintenance and repair costs. Through put and efficiency in the long term is often ignored, so we spend the money, but have little to show for that investment. To recover materials a city needs. ... The poor and migrant people end up working in this sector. There are no toilets or -v amenities for them as they work, since they have no P I designated spaces. This e 0. again needs to be factored W into the design of the city. . A In addition, their skills and ability to deal with litter and materials needs to , grown and capacities built. & Process Looking for what works is a great place to start at the granular level. If people have adapted and found a way, it means that it works. We must look for examples of positive deviance in the sea of garbage to find new processes and methods for material recovery. Let us not forget that Waste in India is more a mindset challenge not a technological one.
