4.2.5 ADVANTAGES OF BIOMINING
1. Recovered materials such as ferrous metals, plastic, aluminium, and glass can be
sold if markets exist for these materials.
2. Reclaimed soil can be used on site as daily cover material on other landfill cells,
thus avoiding the cost of importing cover material. Also a market might exist for
reclaimed soil for use in other applications such as compost.It can thus avoid cost
of virgin soil and save the natural resource.
3. Combustible reclaimed waste can be mixed with fresh waste and burned to
produce energy.
4. By reducing the size of the landfill footprint through cell reclamation the facility
operator may also be able to either lower the cost of closing the landfill or make
land available for other uses.
5. The value of the land that is thus reclaimed, when deployed for other uses.
6. Hazardous wastes if uncovered during biomining especially at older landfills could
be managed in an environmentally sound manner.
7. Decreased or completely avoided expense of any closure procedure and the
monitoring that follows such closure procedures.

4.3 TECHNOLOGYSELECTION

From the field observation, it is evident that the dumping ground is a great
nuisance to the citizens of Rishikesh. Also, considering the ultimatum given by the
land owner to vacate the site, there is no other option than recovering the land by
way of removing the legacy waste accumulated at the site. Since site needs to be
handed over to the owner, scientific capping of dumpsite may not be a right option
as no further development could be undertaken on the scientifically closed
dumpsite for at-least 15 years of time.
