2.6 PROPOSED DISPOSAL OPTIONS FOR DIFFERENT<br />
CATEGORIES OF HAZARDOUS WASTES<br />
The management <strong>of</strong> hazardous waste would require the follow<strong>in</strong>g aspects<br />
Collection and handl<strong>in</strong>g <strong>of</strong> hazardous wastes at Unit level<br />
Temporary Storage Facility <strong>of</strong> hazardous waste at each Industrial<br />
Estate/area.<br />
Transportation <strong>of</strong> hazardous wastes from the <strong>in</strong>dividual unit to<br />
Temporary Storage Facility and from Temporary Storage Facility to common<br />
"treatment, storage & disposal facility" (TSDF)<br />
<strong>Pre</strong>-treatment Facility <strong>of</strong> hazardous wastes at TSDF<br />
F<strong>in</strong>al <strong>Disposal</strong> at TSDF<br />
The TSDF comprises <strong>of</strong> waste receiv<strong>in</strong>g facility, laboratory facility for<br />
characterisation, temporary storage facility, pre-treatment unit (physico- chemical<br />
treatment) and secured landfill facility.<br />
The distribution <strong>of</strong> total quantity <strong>of</strong> hazardous waste for Physico-chemical treatment,<br />
Inc<strong>in</strong>eration, Recycle/reuse and disposal to Secured Landfill Facility (SLF) is shown<br />
<strong>in</strong> Fig 2.3. The management plan for the various types <strong>of</strong> hazardous wastes<br />
generated from major <strong>in</strong>dustrial estates/ areas is shown <strong>in</strong> Fig 2.4. From this it can<br />
be observed that the maximum quantity <strong>of</strong> landfill disposable hazardous waste i.e.<br />
about 32 % <strong>of</strong> total landfill disposable waste is generated from Wazirpur Industrial<br />
area (1) followed by 11 % from SSI Industrial area (7). From other <strong>in</strong>dustrial areas<br />
the quantity <strong>of</strong> landfill disposable waste varies from 3 to 7 % <strong>of</strong> total landfill<br />
disposable waste. As the quantity <strong>of</strong> hazardous wastes to be disposed <strong>of</strong> <strong>in</strong> SLF is<br />
as high as 90 % <strong>of</strong> total quantity <strong>of</strong> hazardous wastes generated, the distribution <strong>of</strong><br />
rema<strong>in</strong><strong>in</strong>g 10 % hazardous wastes for Physico-chemical treatment, Inc<strong>in</strong>eration and<br />
Recycle/reuse is shown <strong>in</strong> Fig 2.5.<br />
