Have you ever wondered what happens to your waste once you throw it out?
Waste is an issue that has fascinated me since I arrived in India about 6 months ago. Although waste is often very visible on the streets here, I had a very limited understanding of how the waste management process worked. Although it may sound a bit odd, I was really curious to find out where my garbage was going. I guess I felt like I couldn’t take any effective action until I had seen it for myself and understood the complexities of the situation.

I started doing some of my own research into the issue and a friend introduced me to a business called Daily Dump, based in Bangalore. Daily Dump sells composting equipment, and also runs a “Trash Trail” tour across the city. So I signed up and arrived at the Daily Dump office early one Saturday morning with 7 other interested citizens. The staff gave us a quick powerpoint presentation to set the scene:
I was amazed to find out that only 10% of what we currently throw out should be heading to landfill!
To make sure we understood the different types of waste, we tried to segregate some dry waste that we’d brought along – such as cardboard boxes, plastic bangles, plastic milk bags, plastic bottles. Most items were easy to sort, but some, such as cellophane and chip packets, were more of a challenge.
Lesson 1: The metallized polyester used for disposable chip and biscuit packaging (a mixed material) is not recyclable.
Packed into a minivan, we then spent the rest of the day physically tracing the progress of garbage – from household hand collection, to a local street corner, neighbourhood transfer point, wholesale market, plastic recycling plant and then to its final resting place in landfill.
Stop 1: Household collection, street sweepers, local carts
People are employed by the authorities to collect garbage bags door to door and use carts to bring all of the waste together at a street corner.

Stop 2: Local street corner
From this street corner, an auto pickup then collects the dumped rubbish and takes it to a neighbourhood transfer point.

Stop 3: Neighbourhood transfer point
At the transfer point, a large compactor truck collects all of the garbage and takes it to one of Bangalore’s landfills.

Stop 4: Kabbadiwalla
Throughout these initial stages of the waste collection process, both informal and formal workers attempt to salvage valuable recyclable items, as they can make some supplementary income by selling them to a Kabbadiwalla (a local trader). However, this is made much more difficult for them when the dry and wet waste are not segregated at source.
A migrant worker searches through dumped garbage for any items of value. We all donned some plastic gloves and helped him, just about blocking the street in the process, as curious passers-by stopped to see what we were doing.

These workers are very skilled and have learnt from experience to be able to distinguish different types of glass, plastic and metals. This is often done by touch, but can also be done by burning the material, hitting it on a rock or testing them with small amounts of chemicals.
Lesson 2: It is critical to recognise the unique contributions and value of everyone who is part of the waste management process (either informally or formally).
