Waste Bin Requirement Calculator

Work out waste bin requirement instantly with clear inputs, formula shown and shareable results.

About Waste Bin Requirement Calculator

Total waste is attendees times waste per head, and the bin count divides that by the capacity available across the planned number of collections. Mid-event collections multiply effective capacity, which is usually cheaper than placing twice as many bins around a site.

Formula

Bin count

bins = ceiling(total litres / (bin capacity x collections))

Worked example

With the default values below, Waste Bin Requirement Calculator returns Bins required of 7. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
