Finished Compost vs Weekly Kitchen Scraps
Formula
## How to Calculate Compost Volume Composting reduces organic waste volume by 50-75% while producing nutrient-rich soil amendment. ### Formula **Finished Compost = Input Volume * (1 - Reduction %)** ### Volume Reduction - Hot composting: 60-75% reduction - Cold composting: 50-65% reduction - Vermicomposting: 70-80% reduction Composting diverts 30-40% of household waste from landfills.
Exemplo Resolvido
5 gal kitchen scraps and 10 gal yard waste weekly for 52 weeks with 65% volume reduction.
- 01Total input: (5 + 10) * 52 = 780 gallons
- 02Finished compost: 780 * (1 - 0.65) = 273 gallons
- 03In cubic feet: 273 / 7.48 = 36.5 cu ft
- 04CO2 avoided: 780 * 0.005 = 3.9 metric tons
Perguntas Frequentes
What can I compost?
Compost fruit/vegetable scraps, coffee grounds, eggshells, yard trimmings, leaves, and shredded paper. Avoid meat, dairy, oils, and pet waste in home compost.
How long does composting take?
Hot composting produces finished compost in 2-3 months. Cold composting takes 6-12 months. The key factors are carbon-nitrogen ratio, moisture, aeration, and particle size.
How does composting help the environment?
Composting diverts waste from landfills where it would produce methane (a potent GHG), returns nutrients to soil, reduces need for synthetic fertilizers, and improves soil water retention.
