Diversion Measurement

The methodology used to calculate diversion is based on the Title 14, California Code of Regulations, Article 6.1 Solid waste Generation Study, Section 18722 et seq, and is consistent with CIWMB measurement protocols. The following equation defines the “Generation-Based Diversion Quantification Methodology”:

Generation = Disposal + Diversion
Diversion Rate (%) = Diversion TonsGeneration Tons X 100

How to convert pounds into tons:

To convert pounds to tons, divide the number of pounds by 2000 (1 ton = 2,000 pounds).

Example: 700 pounds (lbs) ÷ 2000 pounds/ton = 0.35 tons

How to convert cubic yards into tons:

Select the type of material recycled/reused from the chart on the right

Multiply the corresponding number by the total number

of cubic yards recycled/reused.

1 cubic yard of asphalt = 0.69 tons (T)

Example: 5 cubic yards (cy) of asphalt =

5 cy x 0.69 tons per cubic yard = 3.45 tons

Salvaged Materials:

Please estimate the quantity of material recycled/reused. Your estimates should be provided in tons.

Example: 25 pounds ÷ 2000 pounds per ton = 0.02 tons
