New feedstock, Animal Rendering waste, Brooks Compost Facility, Chatham County
Hello Amy,
The Solid Waste Section has reviewed the proposed new feedstock, animal processing waste from Valley Proteins, for
the Brooks Compost Facility, 1905-COMPOST. The Section has no objections to this material being accepted for
composting at this facility.
Feedstocks from animal rendering plants may be accepted at Brooks Compost, without future notification, if the waste
consists of animal rendering products only and no other additives. Very small amounts of cleaning fluid are acceptable
in the waste.
Measures should be taken to prevent and control offsite odor with the initial acceptance and mixing of the waste.
If you have any questions, please let me know.

Hi Donna, I hope this finds you well !
See attached and let me know if you need anything else.
Also, If you could please notify me when you receive this I would appreciate it. We are looking to receive the first loads
as soon as this is cleared.

Thanks and have a great weekend!

Mrs. Wilson,
This letter is to notify you of a request to add another waste material to the list of acceptable
feedstocks for Brooks Compost Facility, SWC-19-05 . The material in question is specifically from
the Valley Proteins plant in Fayetteville, NC and is called a "belt press sludge." The production
of this waste material is described by the facility's management as the following:
"VP collects parts from rendering plants and brings them to their processing center where
everything collected is placed into a huge vat and basically liquified. From there, everything is
sluiced into a pond where it sits and allows the proteins to rise to the top. The proteins are
skimmed off of the pond and run through the belt press which produces a material that has the
consistency of something like silly putty. This consists of the proteins from the renderings after
it has been liquefied and pressed out. No bleaches or cleaners are used in the process."
Also attached are recent analytics derived from an on -site visit where Alan Brooks, Manager for
Brooks Compost Facility, toured the facility and observed sample collection that was then taken
directly to Pace Analytical, Bob Rubin, acting as an experienced consultant for Brooks
Contractor, has also included a letter addressing the benefits and recommendation to accept as
a long-term feedstock, considering the properties of the waste. When approved, the waste will
be received on a trial basis where test windrows will be made. As Mr. Rubin notes, caution will
be taken to develop a new batch recipe that keeps windrows within ideal C:N ratios. Odors will
also be a factor in the receipt of the material; however Brooks Compost Facility is well adapted
to utilizing odorous feedstocks such as hatchery waste (eggshells) by immediately covering or
incorporating them with carbon. For the initial test windrows, belt press sludge will be off-

loaded into the solidification basin and then immediately blended with stockpiled carbon to
create a shorter test windrow from which to test heating abilities as well as dilution factors.
The batch will be tested several times in -windrow and then again after going to curing. The
finished compost created will be evaluated for physical and chemical properties, as well as
practical applications in agriculture and landscaping. Germination trials as well as microscope
analysis will be performed to make sure the feedstock will be beneficial to plant growth and
overall soil health. After initial testing to determine its benefit, Brooks Compost Facility intends
to accept this type of material from other locations.
Anticipated long-term volume is 4000 + Tons per year. Brooks Compost Facility intends to
continue accepting agriculture and food -grade waste originating from large-scale poultry
operations, as it makes up a large portion of available wastes in Central North Carolina, The
Central location of Brooks Compost Facility is ideal to continue supplying large-scale agricultural
production efforts with efficient and environmentally -friendly waste management services, as
well as supplying valuable soil -building compost.
A timely response is greatly appreciated by the waste generator. Please let me know if you have
any questions or need further clarifications.
Thank you for your time and assistance,
Amy Brook ulford

QUALIFIERS
Project: Valley Proteins 3/1
Pace Project No.: 92590832
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL -Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
ANALYTE QUALIFIERS
D6 The precision between the sample and sample duplicate exceeded laboratory control limits.
H1 Analysis conducted outside the EPA method holding time.
H2 Extraction or preparation conducted outside EPA method holding time.
H3 Sample was received or analysis requested beyond the recognized method holding time.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
N2 The lab does not hold NELAC/TNI accreditation for this parameter but other accreditations/certifications may apply. A
complete list of accreditations/certifications is available upon request.
R1 RPD value was outside control limits.

Dear Ms. Brooks;
14 June 2022
Subject: Belt Press sludge, Valley Protein, Fayetteville, NC
Thank you for providing the analysis of the belt press sludge from the Valley Protein Facility in
Fayetteville. The waste analysis is Pace Report92590832, March 2022. The waste analysis shows
low levels of regulated metals and a very high level of organic nitrogen. The organic nitrogen
expressed as TKN can be a very valuable addition to the compost.
The waste analysis shows levels as below in mg/kg (or % where specified):
Ca —1770
Fe —1510
Ni (a regulated metal) — 6.6
Mg — 6610
K — 6520
Zn(a regulated metal) —102
Hg (a regulated metal)— 0.077
TKN—106000
NH3 — 824
P - 7550
Solids 9.3%
The TKN value is high. This represents 10% organic nitrogen (the ammonia is .1% of the TKN)
This nitrogen is of great value to crops and to the compost operation. Special calculations will
be required to assure the C:N values remain above 20:1 and these calculations can be
accomplished as the material is assessed to determine the relative percentage of available
nitrogen in the early stages of the process.
The levels of Magnesium, Phosphorus and potassium are excellent. The presence of these
cations will be beneficial to agricultural, silvicultural and horticultural users. The levels of the

regulated metals in the material are very low and none approach any of the regulatory levels
established in federal or state rule.
The belt press sludge could be very beneficial to the compost operation at Brooks. Based on
this review of the quality of the material there is no reason to believe it will adversely impact
the quality of the finished compost product generated at Brooks.
I hope this is helpful to you and please feel free to share this with state agency personnel and
others.
Respectfully Submitted
