Work out landfill life instantly with clear inputs, formula shown and shareable results.
Remaining life at constant input is simply capacity divided by annual input, but growth compounds and shortens it materially over a long horizon. Additional diversion to recycling or energy recovery extends life proportionally, which is usually far cheaper than permitting new void space.
Simple life
Life (years) = remaining capacity / annual input after diversion
With growth
Annual input grows geometrically; life is the year in which cumulative input exhausts capacity
Landfill capacity and final contours are set by the environmental permit and planning consent. Overfilling beyond permitted levels is a breach.
Permitting, land acquisition and construction of a new landfill cell commonly take five to ten years. A site with eight years of life left is already at the decision point.
Yes. Waste settles 10-25% of its placed depth over decades, and some of that can be recovered by overfilling within the permitted final contours, subject to stability and capping design.
