What are the principal benefits for operating a landfill that acts as a bioreactor?
Key benefits of a landfill bioreactor can be defined as follows:
1. Increased Landfill Capacity
One important result of quicker and absolute decomposition of solid waste in bioreactor
is added disposal ability which can be used during the active lifetime of landfill as; it would
generate additional revenue for the landfill operator.
2. Reduced Leachate Management Costs
Leachate recirculation in bioreactor may reduce leachate management costs via
compensating the need of off-site treatment or disposal of leachate. Further, liquid wastes such
as; sewage sludge can also be applied to fulfill the demand of supplementary liquid addition.
3. Improvement in Landfill Gas Management
Landfill gas generation can be accelerated with the assistance of a bioreactor. It can
enhance the possibility of utilization of this gas in a profitable mode.
4. Reducion in long lasting responsibilities
Since bioreactor promotes rapid and complete decomposition of solid waste therefore; it
can trim down the necessity of long term care as well as environmental monitoring because;
entire steady waste mass of closed bioreactor reflects a low probability of generation of
any atmospheric problem in future.
