Construction waste segregation bins calculator

Calculate bins per interval by stream and total bin lifts over horizon with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use bins per interval by stream and total bin lifts over horizon to compare changes to your inputs. The method and limits below explain the scope.

Calculation method

Calculation method

Bins per interval by stream

J([[r[0],ceil(r[1]/r[2])] for r in a])

Total bin lifts over horizon

b*sum(ceil(r[1]/r[2]) for r in a)

Unused per-interval bin capacity (m³)

sum(ceil(r[1]/r[2])*r[2]-r[1] for r in a)

Symbols and units
a
JSON Waste streams [ID,m³ per collection interval,usable bin m³]
b
Forecast collection intervals (count)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Calculation steps and notation

sum(list) adds all entries in the list.

Assumptions & limits

Assumptions & limits

  • Fixed repeating collection interval from user forecast; streams remain segregated. Waste classifications, container ratings and collection authorization supplied externally. Supported limits: All numeric inputs must be finite. Only the explicitly described mathematical scenario is supported.
Are these inputs private?
