# Diversion Rate ## Calculating Your Diversion Rate

### Formula

Diversion rates measure (usually by weight) the portion of waste not sent to the landfill. Tracking your diversion rate over time is a great way to measure of the effectiveness of reuse, recycling, and organic composting programs.

### The formula for calculating your diversion rate is: To find your diversion rate:

• Divide the Weight of Diverted Waste Only by the Weight of All Waste.
• Multiply the quotient by 100.
• The result is your Diversion Rate.

### Example

As an example, let us examine the hypothetical office building with both recycling and composting programs.

Table 1 shows the monthly weight for each waste stream.

Total Weight (lbs) 2,340 Recyclables 1,200 Organics (compostable) 690 Garbage 450

### For this scenario, the diversion rate equation looks like this: To find the diversion rate:

• Add the weight of Recyclables and the weight of Organics.
This will be your dividend.
• Add the weight of Recyclables, Organics, and Garbage.
This will be your divisor.
• Divide the sum of Recyclables and Organics by the sum of Recyclables, Organics, and Garbage.
• Multiply the quotient by 100.
• The result is your Diversion Rate.

### Now, we plug in the numbers from the table: To find the diversion rate in this case:

• Add the weight of Recyclables (1,200) and the weight of Organics (690). This will be your dividend.
• Add the weight of Recyclables (1,200), Organics (690), and Garbage (450). This will be your divisor.
• Divide the sum of Recyclables and Organics (1,890) by the sum of Recyclables, Organics, and Garbage (2,340).
• Multiply the quotient by 100.
• The Diversion Rate is 80.8%

In the above scenario, about eighty-one percent of all waste produced is diverted from a landfill because this office implemented recycling and organics waste diversion programs.
