E-Waste
Previously one common bin for entire complex
Common bin mixed up with general waste due to lack of
monitoring
Have rolled out block-wise bins with lock/key now
Vendor constraints are challenging to meet
Recycling chain difficult to establish
Many new vendors coming up – Closed contract with one
new vendor now

Rejects
Daily Collection
Disposed through BBMP
Target is <1% of overall waste generated
Difficult to classify every material into one of the identified categories
for recycling
Quadruple burden: BBMP vendor charges + SWM cess with property tax +
KSPCB CFO charges + cost of running WM programme
