A presentation by the SADA ZERO initiative - Zero Waste in Sadashivnagar - that describes how they started, how they monitor and how they plan to expand to other streets in their layout.
4. The process
Mixed waste in home Taken in auto to common
collection point. Waste collectors
wade through pile and recover
small amount of saleable material
Sent to dump near Hoskote Transferred to truck
5. The tragedy
Wasted Wasted
Wasted
Wasted
Recycled
Wasted
Valuable recyclable material is mixed with wet waste and hence not
usable. Less than 10 % is recovered.
6. The people
BBMP contractor's team of 9 people, with 2 autos.
Paid Rs. 2400 per month.
Work 7 days a week.
Work 7 AM to 7 PM with a 2 hour break.
No leave.
No medical benefits.
Earned Rs. 200 per month from sale of dry waste.
8. The process
Segregated resource in Collected in large bags
home
Goes to recycling factory Sold to scrap dealer
We no longer call it waste. We call it resource, because it is
now valuable recyclable or reusable material.
9. Segregation categories
Separation of home waste into:
1. Wet waste – from kitchen, garden
2. Dry resource.
- Paper + cardboard
- Plastic + metal
- e-waste + glass
10. Collection method
Wet waste – collected in dustbin, given to waste
collectors daily, as before
1. Kitchen + garden waste
2. Bio-medical waste (cotton, sanitary pads, condoms,
syringes) wrapped in newspaper.
Dry resource – collected in 3 different bags,
given on weekends
1. Bag 1- Plastic + metal
2. Bag 2 - Paper + cardboard
3. Bag 3 – e-waste + glass
11. Collection in apartment complexes
1. Residents store segregated resource in their respective flats for whole week.
2. On collection day morning they dump the resource in 3 drums.
3. Drums are locked the whole week, only opened for a 1-hour window on
collection day.
4. Dumping in drums is under supervison of Sada Zero volunteer, who notes
down the homes that are giving the resource.
12. The collection Gaadi
Designed to be non-motorized, silent,
non-polluting.
Version 1 – too small
Version 2 – too small, heavy
Version 3 - big enough, still too heavy.
14. The people - collectors
Same team. Now called resource collectors (RCs).
We thought they were the best people – they know the
locality, the process, places to sell the resource.
They sell the resource, keep the whole money.
Now earn Rs. 1000 a month each from sale of
resource.
Don't have to wade through
mixed waste to recover Resource.
They segregate the 3 categories
into 10.
15. The people - volunteers
Residents of Sadashivanagar.
Total around 30 people.
Meet every alternate Tuesday.
Distribute various tasks (enrolling new volunteers,
performing skits to educate residents, coordinate with
resource collectors..).
16. Starting on a new street
We start segregation on a street when
we have 3 volunteers for it (who need be
residents of the street).
Enrol volunteers, train the volunteers.
Map the homes – get house nos., names,
mobile nos. on a mapping sheet.
Do a presentation for the residents to explain
the Why and How of segregation.
Distribute bags to homes.
Decide on a date and time for weekly
collection.
17. Weekly collection system
The day before the collection day, send SMS reminder to
homes to keep bags ready.
Till a street hits 65 % 'Full segregation + bags at gate',
volunteers walk with Gaadi on collection runs, note down
homes doing partial segregation, full seg., 'not at gate'.
Typical time 1 month.
After this, volunteers do a 'maintenance
walk' once a month to supply lost bags,
record habitual 'not givers'.
Every week's % for various streets is
Tracked as a graph, put up on internet.
18. Some rules we follow
Volunteers collect resource personally:
- Erase stigma associated with 'garbage'.
- Social pressure on people to participate.
- Get people involved in civic issues, by example.
System must be self-sustaining, run by resource
collectors. Only motivation is money from sale of resource
– they keep 100 %.
Should benefit resource collectors
in various ways – health, time, money.
Take things 1 step at a time, in phases.
Don't try to fix everything at once.
19. By now you're thinking
Why aren't these idiots doing anything about the
wet waste ?
We don't want to bite off more than we can
chew.
Phase 1 : Dry waste segregation in 7 streets
(300 homes). Done.
Phase 2 : Extend to 10 more streets. Doing
now.
Phase 3 : Stop waste accumulation in streets,
from homes and passers by.
Phase 4 : Community composting
of wet waste, leaves.
20. Some challenges – ideas welcome
Collection % : 'Full segregation + bags at gate' doesn't
seem to go beyond 70 %.
Collectors : Still have to micro-manage them on
collection days. Issues with punctuality.
Collection vehicle : Still experimenting, trying to make a
light-weight, non-motorized, cheap vehicle.
Space : Looking for public place to store collection
vehicle, do sorting, store unsold resource.
21. All our system documents are available on the internet.
