Waste bins of various types are distributed over the campus in different locations
to ensure waste is not dumped at roadside. Different types of waste bins namely
cylindrical concrete bins (CON), small wooden bins (SB), cubic concrete bins (CUB),
masonry hut bins (HUT) and stone bins (STB). Hut bins are constructed at key
locations where quantity of waste expected is quiet high. Daily collection at
hut bins constitutes about 20% of total solid waste in the campus. Different
type and number of bins at IISc campus are listed in Table 1.

Small bins are provided to collect frequently generated wastes such as cigarette
covers, envelopes etc. and are placed at strategic positions. Concrete bins,
stone bins and cubic bins are provided at places, where waste is expected
regularly. Apart from this, at various locations wastes open dumping on ground.
In some localities such as duplex, E-Type, D-Type and Tunga residential staff
quarters door to door collection is being attempted recently. Collection charges
per household per month are Rs.15. Regular street sweeping and roadside garden
trimmings are done and wastes are dumped in bins and sometimes in drainage also.
