How do you calculate landfills?

The current and final configuration of the landfill is used to determine the current and final volumes. The remaining capacity is calculated by subtracting the current volume used from the final volume (final capacity – existing capacity = remaining capacity).

How can you extend the life of a landfill?

Minimizing the area of the working face and tipping deck can help extend a facility’s life by reducing the amount of material required to cover the face at the end of each day.

How do you calculate waste generation rate?

Waste Generated was calculated as the sum (in tonnes) of Waste Diverted plus Waste Disposed. Waste Generated per capita was calculated using Waste Generated divided by population.
