                      Dumpsite reclamation or mining creates additional space for future land filling needs
                      and  avoids  or  reduces  the  cost  of  acquiring  land  for  dumping  of  municipal  waste.
                      Further  potential  for  groundwater  contamination  is  reduced  through  remediation  of
                      unlined  open  dumpsites.  In  addition,  it  also  reduces  the  cover  requirements  for
                      existing dumps by reducing the footprint of the landfill.
                      The process of rehabilitating a dumpsite to a sustainable landfill may be done in a
                      phased manner depending on the risk posed by the dump and its financial aspects as
                      well. Dumpsite reclamation involves excavation, screening, and separation of material
                      from  dumpsites  into  various  components  such  as  soil,  recyclable  materials,  and
                      residues.viz. oversized material, intermediate sized waste and soil or humus.



                 4.2.1 EQUIPMENTS AND MATERIALS
                      The  biomining  process  involves  multiple  machineries  and  vehicles  at  different
                      stages  of  the  process.  The  required  machineries  and  materials  for  biomining
                      activity may include but not limited to:


                                                                                                        40
