Frequently Asked Questions

What factors affect how quickly a compost bin fills up? +
The main factors include the amount of material you add daily, the size of your compost bin, and the efficiency of the decomposition process (which impacts how much the volume reduces). Proper aeration, moisture, and a good mix of ‘greens’ and ‘browns’ contribute to faster decomposition.
How does ‘volume reduction’ work in composting? +
As organic materials decompose, they break down and compact significantly. This means the initial volume of your waste can reduce by 40% to 70% or even more, depending on the materials and composting conditions. This calculator uses a percentage to estimate this reduction, giving you a more realistic fill rate.
Can I use this calculator for different types of compost bins? +
Yes, this calculator is designed to be versatile for various bin types (e.g., tumblers, heaps, stationary bins) as long as you know your bin’s total volume and can estimate your daily waste input and decomposition rate. The principles of volume in and volume out remain the same.
