old grease on a national scale.

Business Segments

Darling operates a fleet of approx 1,000 trucks to collect raw materials from
approx 115,000 food service establishments, butcher shops, grocery stores, and
independent meat and poultry processors nationwide.

“Formula” basis: Applied to approx 55% of Darling’s annual raw material
volume; cost is tied to published finished product commodity prices after
deducting a fixed service charge.

“Non-formula” basis: Applied to remaining volume; suppliers are either paid a
fixed price, are not paid, or are charged for the expense of collection, depending
on various economic and competitive factors

Darling markets finished products worldwide.
Primarily BFT and YG, and also MBM, a protein;
Oils used in pet food, animal feed, soaps;
Oleo-chemical producers use oils to produce ingredients for paint,
rubber, paper, concrete, plastics;
MBM is used as high protein additives in pet food and animal feed

Operating Cash Flows

Renewable Fuels

• Fuels produced from bio-mass or
non-petroleum sources

• Only work with mandates/subsidies or high oil prices

• Dependent on Washington D.C.

- Direct subsidies

- Mandates (Congress recently set significant targets
which now includes bio-fuels as well as ethanol.)

Competitive Advantages

• Darling is uniquely positioned to capitalize on emerging
bio-fuel opportunities.

- Concentrated regions which source large, stable
supplies of raw materials

- Top producer of rendered fats and greases

- Historically, animal fats and greases have
traded at a discount to vegetable oils

- Elasticity of animal fats and greases decouple
it from the food vs. fuel debate

- Animal fats and grease will ultimately trade
BTU equivalent over time

4 Opportunities Exist Today

1: Alternative Fuel Mixture Tax Credit

• Pays Darling 50 cents per gallon to burn
fats/greases in our boilers

• Opportunistic calculation versus natural gas

• Limited to no capital involved

• Current subsidy is through 2009

• Proposed legislation extends through 2012

4 Opportunities: Bio Diesel

2: Bio Diesel
Production of a Fatty Acid Methyl Ester
from a triglyceride feedstock

• Process is well known and fully commercialized

• Issues exist with handling FFA, metals, phosphorus
and other contaminants

• Finished product has cold flow issues but are
diminished when blended at 5% or less

• Several animal fat plants under construction or
contemplated in U.S., Europe and South America

• $1.00 per gallon for virgin oils and $.50 cents per
gallon for used cooking oil

4 Opportunities: Green Diesel

3: Green Diesel
Green or renewable diesel is the process of
converting a triglyceride to a hydrocarbon.

• Utilizes known petroleum-focused processes

• Finished product is more fungible than bio-diesel
- Higher Cetane
- Better cold flow properties
- Zero sulfur for upgrading distillate streams
- Pipeline ready

• $1.00 per gallon for both animal fats and used
cooking oil.

4 Opportunities: Co-Processing

4: Co-Processing
The introduction of vegetable oils, fats and
greases as a blend feedstock with petroleum.

• Introduced at 2-5% with distillate stream prior to hydro
treating

• Allows petroleum companies to participate in
renewable fuels, however, it displaces current
refining capacity and adds no new capacity

• Legislation has been introduced to defeat or
minimize this opportunity

Renewable Fuels: What’s Next?

• Waiting for Washington to clarify final subsidies

• Technology is rapidly evolving

• Potentially green diesel is a better solution

• Ultimately DAR is well positioned to participate
