Example 1
- 3 kg
- landfill 60%
- compost 30%
- factor 2
- factor 0.4
- decay 0.7
2.2 kg CO₂e · per week
How much food waste from 3 kg and 60/30%? 2.2 kg CO₂e · per week. A week, not the city.
Type kg, landfill %, compost %, factors and decay. 3, 60, 30, 2, 0.4 and 0.7 give 2.2 kg CO₂e · per week. 2 kg give 1.0. 5 kg give 5.0. A week, not a year.
A week. 3 kg and 60/30% give 2.2 kg CO₂e · per week. Not the city. Empty optional fields stay empty.
Enter data and click Calculate.
Food waste in this calculator is net weekly CO₂e from landfill minus compost. 3 kg, landfill 60%, compost 30%, factor 2, factor 0.4, decay 0.7 give 2.2 kg CO₂e · per week. The second set gives 1.0 kg CO₂e · per week. The third gives 5.0 kg CO₂e · per week.
landfill = kg × share × factor × decay. compost = kg × share × factor. net = max(0, landfill − compost). At 3 kg the second line is 2.5 kg.
2.2 kg CO₂e · per week is not a waste fee. 1.0 kg CO₂e · per week is more compost. 5.0 kg CO₂e · per week is 5 kg and 80% landfill. Optional fields stay empty.
Waste and recycling next door uses a year and 0.45/0.12. Water footprint counts litres. Here the week stays: 3 kg and 60% stay 2.2 kg CO₂e · per week.
Type 3, 60, 30, 2, 0.4 and 0.7. Then Calculate. 2.2 kg CO₂e · per week. 1.0 kg CO₂e · per week. 5.0 kg CO₂e · per week.
The first set gives 2.2 kg CO₂e · per week. The second gives 1.0 kg CO₂e · per week. The third gives 5.0 kg CO₂e · per week. Another landfill share at 3 kg changes 2.2.
landfill = kg × land% × factor × decay. compost = kg × comp% × factor. net = max(0, landfill − compost). Suffix · per week.
A week. 3 kg and 60/30% give 2.2 kg CO₂e · per week. Not the city.
2.2 kg CO₂e · per week
How much food waste from 3 kg and 60/30%? 2.2 kg CO₂e · per week. A week, not the city.
1.0 kg CO₂e · per week
How much at 2 kg? 1.0 kg CO₂e · per week.
5.0 kg CO₂e · per week
How much at 5 kg? 5.0 kg CO₂e · per week.
2.2 kg CO₂e · per week. Landfill minus compost, not the city.
1.0 kg CO₂e · per week. More compost.
5.0 kg CO₂e · per week. More landfill.
No. A week and typed factors. EPA sits outside this calculator.
That card uses 0.45 and 0.12 and (est.). Here a week and other factors.
Yes. 0,4 and 0.4 are the same compost factor.
No. Options stay empty. The result is the week sum.
On the second line as landfill. Examples take 2.2 kg CO₂e · per week.
Net does not go below 0.
