Everyone knows that Dhaka is among the filthiest cities in the world. There are enough reasons behind it as well. For instance- every now and then we see bins overflowed with bags of scraps and plastic bottles. Garbage is often left uncollected on the streets for weeks, attracting flies and roaches. Such inefficient household waste management system has put the environment of this city in jeopardy. And interestingly Dhaka city corporation authorities have utterly failed to transform the capital into a clean city despite different projects and allocation.
