Formula
50% do orgânico
About this calculator
The composting benefits calculator estimates organic waste reduction when adopting composting practices. Using a 50% reduction formula, it calculates how much organic waste can be turned into fertilizer, avoiding landfill disposal. This is useful for calculating space savings in waste and environmental benefits.
It works by multiplying the amount of organic waste generated (in kg) by 0.5. For example: a family producing 10 kg of organic waste per week would reduce 5 kg through composting. The result shows waste savings and fertilizer volume, excluding indirect benefits like methane emission reduction.
Use this calculator when planning a home or business composting system. It's ideal for comparing waste costs and assessing impacts in urban areas with disposal restrictions. Note: the formula considers only pure residues (meat, fruits, vegetables). Contaminated materials (oil, plastics) reduce composting efficiency.
Frequently asked questions
Where does the 50% formula apply?
The formula applies to pure organic waste, such as fruit, vegetable, and meat scraps. It excludes kitchen waste with oil or non-organic residues.
How does it impact total waste?
It reduces organic waste mass by 50% and prevents methane generation in landfills, which contributes to climate change.
Do I need to separate waste beforehand?
Yes. The calculation accuracy depends on separating organic waste from other types of garbage.
Is it worth it for small families?
Yes. Even small reductions avoid waste collection costs and generate fertilizer for home gardens.
