4 Conclusion
Even 3Rs concept (Reduce, Reuse, and Recycle) is necessary for sustainable waste
management; however, the 4th R of Energy Recovery from waste must be taken
into consideration before
lling. Energy recovery from waste
is considered as green, clean, and renewable. Energy recovery from mined land
final disposal by land
ll
waste creates bene
t in term of land reclamation and reducing of fossil fuel used.
