Trash is not a waste. Its money, its energy !!
How can waste be managed in kathmandu valley ?
Introduction
Waste management in kathmandu valley has been a problem from long time. Everyday, someone has to pass a big pile of waste on the road/street smelling its impure odour, closing nose and ignoring it. There are different branches and sub branches of government to make Kathmandu clean. In spite of having lots of branches and workers, the management of waste has not been systematic. Neither it has been successful to give a good return of it.
I will show you how waste can be converted into money and energy here.
The following flow diagram shows the complete picture of how the waste comes out of a house and what it gets in return.
Description
Part 1
We live in kathmandu valley where usually millions of tons of trash/waste is collected daily which is neither recycled nor reused. About 10-20% of the total collected trash is screened manually in some places and rest goes into the dumping/landfill site in Sisdol. Not a single people here have understood the value of that waste which they give to the collector or throw it on the street or river or anywhere they feel best to throw.
Part 2
Broadly the waste of a house can be classified into two catagories i.e. degradable like foods and non-degradable like paper, plastic, metals etc. Every house should keep the waste into two seperate dustbins and put them in the respective boxes which will be setup in every streets and locality. Government should setup two dustbins (one for degradable and another for non-degradable) for at least 5 house in common.
Part 3
The waste of the dustbins should be transported to the required location seperatly.
Here, degradable to the compost site or directly to land fill site and non-degradable to waste recycling industry.
Part 4
Waste recycling factory is the place where the non-degradable waste are stored, screened and compressed so that they can be taken to the respective industries. Storage location can be different from the factory location but screening the waste into paper,plastics, metals etc. and compressing them is done in the factory premises.
The rest useless materials are transported to the landfill site.
Part 5
Industries is the place where the waste are again reused as raw materials to make respective products.
Part 6
Land fill sites is the place where waste is collected from all over Kathmandu valley. In landfill site all the wastes are dumped and they are pressed on the ground by dozers. Then the waste are covered by the thick soil.
Gas can be extracted from this part by digging a hole inside the soil and taking them out by using the pipes. Since there are many layers of wastes compressed, some good amount of gas can be extracted by making sufficient number of gas extraction points.
part 7
Gas is generated from the landfill site which can be used to generate electricity. Generation of electricity isn't that easy but its possible.
Hence, Kathmandu gets four things back from their waste. They are
i) Products
ii) Gas
iii)Electricity and
iv) Compost
Before thinking of any project or any idea we think of its impossibilities or we say its impossible in Nepal. This is the main factor that governs the undevelopment and no change in the country.
I think its possible !! So lets start !!!
