Re: Calculating Percentages of Diversion by Commodity Types
Dear Mr. Carroll:
The question of how CR&R calculates its diversion percentage by commodity-type has been
raised. After discussions and further review by the District's consultant/auditor and CR&R
reporting personnel, please accept this letter as our explanation of how commodity percentages
are attained.
There are basically four issues addressed by the Auditor last year:
1. The methodology used by CR&R in characterizing the loads from our last sort are
accepted by the State CalRecycle as a good estimate of recyclable materials from each
load.
2. The selection of loads sorted last year were randomly selected and agreed upon prior to
the sort. There is no State definition as to how many loads to sort, but of course the
more sorts, the better the actual numbers by commodity.
3. The question is'also what the residuals are and why are they useless and non-
.. .
• recyclable. These materials would be to those identified by trained sorters that are
•either of no value, not useful in a recycling process or not recycle at all. This may
include such items as food scraps, styrofoam, soiled papers, mirrored glass, soiled
clothing, other garments, and so forth.
4. Any question about why the master manifest of the Facility is not a good comparison to
actual materials types from Costa Mesa are easily explained in that there are large
numbers of green waste self-haulers delivering to CRT every day, making that material
about 60% of the total (including inert materials). This is not a typical sampling of Costa
Mesa residential and as such has not been used for characterizing the residential waste
stream. Although some MRF's in California utilize a "Facility" characterization for each
individual community's characterization, CR&R has never employed such a program.
With the addition of an organics separation program at the households in the future with green
wastes and food scraps being removed, there may warrant an additional study of the contents
of the recycling cart.
