Conclusion
A total of 452 dump site locations were surveyed for their spatial pattern, size, spread
area, waste nature and composi- tion. The dominant components of wastes recorded in open
dumps located outside the core city area were construction

debris, followed by plastic and organic fraction of waste. Whereas in dumps located in the
core area, the largest num- ber of dumps had organic wastes, followed by plastic and
construction debris. Average height of dump site varies from
0.56 m (core city) to 0.75 m (outside of core city area). At frequent intervals, the dumps in
the core area are cleared and sent to processing or dump sites in the non-core areas. Total
waste quantity dumped in 452 open disposal sites is 213310 Mg, which is 17% of total annual
waste generated in Banga- lore city. The availability of and access to common lands,
abandoned agricultural lands, lower population density, dis- tance from city centre and from
main road networks play an important role in the choice of starting an unauthorized dump
site and for its continued use.
