Renewable Diesel vs Petroleum Diesel Burn Test

Imagine a superior next generation renewable diesel direct to your fleet.

___________________

Star Oilco is delivering R99 Renewable Diesel to fleets now.

Renewable Diesel delivered to your fleet by mobile onsite fueling or in bulk.

Imagine a fuel that is cleaner and drier than your typical diesel fuel bought in Oregon.  Now imagine that this dry and clean characteristic means a better performing fleet.  A fuel that causes less maintenance and increased performance benefits as it relates to your modern Tier 3 Diesel Emission systems.  Fewer DPF (particulate trap) regens and other post engine maintenance issues in your fleet while more power and up time reported by the drivers behind the wheel.  Now add to that a more than half reduction in CO2 emissions and Oregon has incentives for the adoption of this fuel because it is a biofuel.  A biofuel that outperforms traditional diesel in performance, emissions, and in lifecycle analysis.

That next generation biofuel is her, Renewable Diesel!

Star Oilco can deliver Renewable Diesel to your tank in Oregon and Washington.  If you are looking at this fuel we will work hard to make it easy for you regardless of how small or large your fleet. It is immediately available for bulk customers.   If you are interested in mobile on-site refueling, wet-hosing, construction job site fueling, or a retail option for the fuel we can work with you as well to make that happen.

Do you have a bulk diesel storage tank?

Does that tank seem to have water in the bottom of it and you can’t seem to figure out where it’s coming from?

You call your diesel supplier and they say they know it isn’t them. If that’s your experience, Star Oilco can explain where that water is probably coming from. With the help of Hydrotex, Star Oilco can also lab test your fuel quality and prove we are in improving it as well.

desiccant filter in field

All storage tanks are different. But for the most part, if your tank seems to take on water randomly. It’s probably from the tank breathing. Especially if you have a large above ground tank. In fact, if you tracked it on a calendar it probably happens the same time of year in conjunction with a weather pattern your tank responds to.

How it works is as the temperature changes the tank’s space that is not filled with fuel will breathe in and out. The temperature and air pressure move air in and out of the tank. As does dispensing fuel out of the tank and then refilling the tank. When that happens, especially if you have a significant amount of humidity in the air or misting rain, water makes it’s way into your fuel supply. As temperatures change, moisture is drawn into the tank, condenses on the inner wall of the tank, and then deposits itself on the bottom of the tank.

This water not only poses a risk to your engines, but if your fuel isn’t treated for stability and performance, that fuel is guaranteed to start growing bugs and algae that will spread throughout your fleet and will have your mechanics spinning filters and dealing with random problems due to this diesel biological growth.

This problem is also exacerbated by ineffective fuel additives trying to keep your fuel dry, clean and safe for your injectors to process, which ensures that water does not get absorbed by your diesel. A single drop of water falling out of solution in today’s high pressure fuel rails and your engine can blow an injector.

HOW DO YOU SOLVE WATER IN YOUR DIESEL TANK?

ANSWER: DESICCANT BREATHERS ON YOUR VENTS

Desiccant diagram

Star Oilco recommends Donaldson desiccant filters, given their excellent full line of products and support. More on the full Donaldson Clean Dry Fuel program here: Donaldson Clean Diesel Kits Brochure.

The Donaldson desiccant breaker mounts to the top of a tank at it’s vent point. This addition seals the point of failure for water to get into your tank. Though in some cases it doesn’t stop 100% of water from ending up in your fuel tank, it definitely guarantees you know where it won’t be coming from, the environment around your tank.

(NOTE: If dealing with underground storage tanks also be aware that if you seal the vent with a desiccant filter and you still have incident’s of water, it might be a leak in the bottom of the tank where rain water is making its way into the tank.)

By using Donaldson filters, Star Oilco also gains the benefit of support from Hydrotex PowerKleen diesel fuel lab to analyze fuel to guarantee that the before and after samples of the fuel are moving as expected and the problem is solved. Running diesel samples can cost as much as $200 each time–having a partner that backs up our solutions with ASTM and ISO measured verification is a must.

The first step in getting better performance from your diesel fuel is to test your bulk diesel storage tank.

What is Heating Oil? 1024 512 Star Oilco

What is Heating Oil?

                In the Pacific Northwest heating oil is diesel

New heating oil customers often ask us, “What is heating oil?” Heating oil is diesel fuel and there are several grades and types. For Star Oilco our standard heating oil product is a ultra low sulfur diesel with a 5% biodiesel blend in order to meet Oregon mandates for off-road diesel fuel. That way our heating oil trucks can also serve construction fueling, emergency back up generators, and other common off-road diesel uses.

Star Oilco has a simple Heating Oil FAQ available.

For full on fuel nerds though, check out this more in depth deeper technical dive below.  If we leave anything out please don’t hesitate to ask for those seeking a nerd-level understanding of heating oil, kerosene and bioheat.

There are three typically grades of heating oil you can order

Number 1 Diesel

Number 1 diesel is also called Kerosene or Stove Oil. This fuel has a lighter specification than typical heating oil which enables it to burn better in a “pot burner” or wick heater. Kerosene has its own specification as the fuel used by wick heaters. Kerosene is typically Number 1 diesel but not all Number 1 diesel’s are kerosene due to the need to be taken up by a wick heater. Any biodiesel content in a kerosene product WILL NOT work in a wick kerosene heater. So be very aware of confirming that your kerosene has never come into any contact with a biodiesel blend of fuel.

Red Number 2 Diesel

Red dyed diesel also called Heating Oil, Dyed Diesel, Off-Road Diesel is the default heating oil fuel. The fuel is dyed red to denote no on-road fuel taxes are attached to it. When you call and ask for heating oil, this is the fuel you are requesting. Clear or Green Number 2 Diesel is the fuel sold at retail gas stations and truck stops. That fuel will also work in your furnace, you just are paying for on-road taxes attached to that fuel.

Bioheat or Biodiesel Heating Oil

“Bioheat” is a blend of biodiesel and petroleum diesel to make a lower emission and lower CO2 heating fuel.  Typically Bioheat is Number 2 Heating Oil with a 20% blend of biodiesel or higher in it. It is a drop-in fuel for your heating oil furnace. There is no change other than routine maintenance is required. It is a cleaner burning fuel with a significant drop in CO2 emissions associated with your heating oil fuel consumption.  If you would like more information on biodiesel as a heating oil you can follow this link.

B20 Biodiesel Heating oil provider

Where do heating oil companies get their fuel?

In the Portland, Oregon market, diesel is fungible. Everyone buys or is expected to mix their fuel from each other in some way. Primarily this is due to the Portland/Vancouver market receiving most of its fuel down the Kinder Morgan-operated Olympic Pipeline. Which means all the refiners transporting fuel are mixing their product in transit. Additionally, there are shared terminal locations, which also have co-mingled owned diesel products.

Every refiner is typically expecting to mix their diesel and gasoline products. The difference is in the care a vendor takes to filter the fuel, using additives and continuously check their fuel quality. If you are buying at the absolute lowest price possible, know that there is an incentive to skip any added value of quality assurance.

Star Oilco buys our diesel products from a variety of vendors. The source refiner typically being either BP, Shell, Marathon(formerly Tesoro), Phillip 66, or a number of other refiners.

Portland, Oregon and Vancouver, Washington are not unique in in having fungible diesel and heating oil fuel specifications. Through its Pacific Operations unit, Kinder Morgan operates approximately 3,000 miles of refined products pipeline that serves Arizona, California, Nevada, New Mexico, Oregon, Washington and Texas. With roots dating back to 1956, it is the largest products pipeline in the Western U.S., transporting more than one million barrels per day of gasoline, jet fuel and diesel fuel to our customers. The company-owned terminals also provide additional services, such as liquid petroleum product storage and loading facilities for delivery trucks.

The heating oil and biofuel blends Star Oilco sells its customers

Heating oil is essentially off-road diesel. You can legally use a higher sulfur content for boilers and heating systems than you can off-road equipment and back-up generators. Regardless, we sell the lowest sulfur fuel available and optimize our fuel to be as versatile to our customers as possible. Construction equipment, back up generators and a host of others systems use off-road diesel, as do heating oil systems. Star Oilco sells the same diesel fuel specification for all of our off-road uses.

We also blend this fuel with biodiesel for our customers that want higher blends of low CO2 biodiesel fuels and heating oil. Star Oilco carries nothing but ultra low sulfur diesel fuels. In fact, our minimum blend of biodiesel is a B5 biodiesel blend (5% biodiesel and 95% petroleum diesel) and we also offer B20 (20% biodiesel blend) and B99 (99% pure biodiesel) for our customers.

About Diesel Fuels Specifications 

In the United States, diesel fuel is controlled according the American Society for Testing and Materials Standard D975-97. This standard describes a limited number of properties that diesel fuels must meet. It should be noted that the requirements are all performance-based, meaning they do not mandate the composition of the fuel, only the specific performance related requirements demanded of a fuel for a diesel engine. The requirements of D975 are described below.

ASTM Specifications for Diesel Fuel Oils (D975)*

*More info on ASTM specifications

Diesel fuel is characterized in the United States by the ASTM standard D975, which identifies five grades of diesel fuel. We are only going to talk about the two most popular commercially diesel fuel used — No 1 and No. 2 diesel. The ASTM D975 standard is made up of a series of different tests that check the characteristic ranges of a fuel to confirm it is adequate to operate in your equipment.

In simple terms, they are checking for specific gravity, the vapor point (when it turns into a gas), the flash point (when it catches fire), the dirt content, water content (how much microscopic entrained water) and a host of other requirements diesel must meet in order to be legal to be sold for use in your engine.

Grade No. 1-D and Ultra-Low Sulfur 1-D:

This is a light distillate fuel for applications requiring a higher volatility fuel to accommodate rapidly fluctuating loads and speeds, as in light trucks and buses. The specification for this grade of diesel fuel overlaps with kerosene and jet fuel, and all three are commonly produced from the same base stock. One major use for No. 1-D diesel fuel is to blend with No. 2-D during winter to provide improved cold flow properties. Ultra-low sulfur fuel is required for on-highway use with sulfur level < 0.05%. 

Grade No. 2-D and Ultra-Low Sulfur 2-D:

This is a middle- or mid-grade distillate fuel for applications that do not require a high volatility fuel. Typical applications include high-speed engines that operate for sustained periods at high load. Ultra-low sulfur fuel is required for on-highway use with sulfur level < 0.05%.

Biodiesel Fuels for Heating Oil

Biodiesel is a renewable fuel produced from oil seed crops, used cooking oil, and/or animal fat waste. It is chemically similar to petroleum diesel, and is produced by combining the oil stock with catalysts and then heating it. Biodiesel is not the same as vegetable oil or SVO (straight vegetable oil) and can be used in any diesel engine.

Biodiesel and biodiesel blends significantly reduce tailpipe emissions, especially carbon dioxide, carbon monoxide, sulfur dioxide and particulates (black smoke). ASTM D975 standard, as of 2008, allowed up to 5 percent biodiesel to be blended into the fuel. This is the called B5 — the ‘B’ stands for biodiesel and 5 stands for up to 5 percent biodiesel.

B6 to B20 – ASTM D7467-17:

Diesel blends up to 20% and more than 6% are referred to as B20. Biodiesel is a cleaner burning fuel than petroleum diesel. Using biodiesel can help reduce the amount of harmful emissions released into the air. Emissions such as sulfur dioxide, carbon monoxide, polycyclic aromatic hydrocarbons and other compounds found in diesel exhaust. Read the ASTM D7467-17 standards.

B99 & B100 –  ASTM D6751-15ce1:

These are fuels made of up to 100% biodiesel. Due to environmental regulations, most retailers will carry a maximum of B99. The standards for B99 and B100 are identical. Unlike gasoline, biodiesel can gel at cold temperatures. This can cause stress on fuel pumps and fuel injection systems, or can clog filters or even become too thick to pump to the engine. B99 has a higher temperature gel rate – meaning that it begins to cloud and thicken at higher temperatures – than conventional diesel.

“The cloud point of soybean biodiesel is about 34°F (1°C), whereas the cloud point for No. 1 diesel is about – 40°F (-40°C) and for No. 2 diesel between -18°F (-28°C) and +20°F (-7°C).” (Biodiesel Cloud Point and Cold Weather Issues) The solutions for cold weather involve additives and lower blends to ensure continuous operations. Read the ASTM D6751-15ce1 standards.

       Wet Hose Fueling and Mobile On-Site Diesel Delivery in the Pacific Northwest.

If some days you have more work than drivers…

Wet Hose Fueling Service in Portland

Mobile On-site refueling or “Wet Hosing” is a solution that will push more money to your bottom line and reduce stress on your drivers.  Star Oilco can also merge our mobile onsite refueling service with our national Fleet Card system.

 One bill, labor saving in town and secured fleet fueling over the road.

 

  Top Five Reasons to Use Wet Hosing for your Fleet Diesel Fueling

On-site refueling or “Wet Hosing” is a preferred method for fueling these days. Fleets of all sizes prefer getting their fleet fueling delivered after hours in their yard. The reasons are numerous but at the top of the list, labor is the driving force behind it.

Shaving off even fifteen minutes of labor–which is one of the two highest costs for most fleets, right after diesel–can have a huge payback to the bottom line.

If your fleet is consistently on overtime or short that one extra hour of legal driver time, picking up fifteen to thirty minutes per truck a few times a month can be a huge opportunity. On top of that fleet fueling, your diesel can also save considerably just by controlling where you pay your fuel taxes (Oregon PUC is tax exempt on the fuel bill, while Washington cardlock and truck stops are paying nearly $.50 a gallon in Washington diesel road tax).  Though you are paying IFTA, why pay the tax earlier than you need to.

Call Star Oilco if you have questions and want to examine the payback value of Mobile On-site Refueling compared against your current vendor for diesel. You might be surprised how much it will save you in time, money and management effort.

                         Five Reasons your fleet should use Mobile On-site Refueling:

  1. Driver Time – The most valuable resource your fleet owns.
    • Truck drivers are a limited resource, and they cost more than you can usually measure in money alone. Without calculating the lost productivity of your truck, you are paying over $10 each time you allow your drivers to stop for fuel. Just the out of route, stopping, and getting back on the road time will put refueling your own trucks at a half hour of lost time. As the average fill up we see is under 50 gallons fueling your own trucks will cost you $.20 to $1 a gallon in labor costs alone.
  2. One More Stop – Picking up productivity in your fleet.
    • Getting drivers on the road and without a reason to be out of route pays back dividends. If you pay productivity bonuses, your most productive drivers will thank you as well. Even in fleets where pay is by stop, not based on hourly wages, the ability those few times a year when drivers are so busy they are bumping up against DOT work rules, they will thank you for the convenience of being ready to go the start of each shift and not having to worry about that one more stop on the way back to base. A few extra stops a year is often worth thousands of dollars to your bottom line–more than a cost of a tank of diesel.
  3. Save on the Cost of Diesel
    • Today the price of diesel at gas stations, truck stops, and other retail options is high compared to wholesale rack averages.  It is not uncommon for our customers to get an extreme labor savings with Mobile Onsite Fueling while also saving on the cost of diesel at the end of the month.  If you are using a credit card to buy fuel, the added Credit Card pricing of diesel is usually $.10 or more cents a gallon. Cut out the retail mark up on fuel and get a cost-plus deal with a true wholesale diesel seller delivering into your yard after hours.
  4. Easily Integrates with cardlock and other fleet cards onto one bill easily.
    • If you have a major hub with a critical mass of trucks in town, wet-hosing yPride Advantage Sample Cardour fleet can pay back rapidly. Even if the majority of your fleet is over the road and out of town, on-site refueling can be a money saving proposition. You can also integrate it seamlessly with a Pacific Pride, CFN, Fuelman, Voyager or another fleet card program as well. Star Oil can provide a Pacific Pride or Fuelman card that will work over the road consolidating all your fuel into one bill. Star can also accept Fuelman, Comdata, WEX or Voyager and bill those fleet cards directly with onsite refueling. Call if your fleet uses one of these national fleet cards and you want to move to wet hosing billed directly to the card and license plate of each one of your trucks. (For further reading on corporate fleet card security features please read our article on Upgrade your Fleet Card’s Security Features)
  5. Cost Plus Diesel – Budget to know every day you are getting a good wholesale rate for your fleet.
    • Star Oilco can connect your fleet to an agreed and easily verifiable cost plus supply agreements. Be it OPIS Average or Low Rack Plus agreements we can guarantee you have a good wholesale price of fuel. On-site refueling will provide a simplified fleet management experience for both your drivers and your Accounts Payable department. Call us if you want to talk about what this can do for your business.

Make And Keep Your Diesel Fuel A Lot More Clean

                               Make And Keep Your Diesel Fuel A Lot More CleanClean, dry, premium diesel

What is Clean Diesel? 

Clean diesel is free of the contaminants that harm modern diesel engines. Today, there is a gap between ASTM diesel standards and the ISO cleanliness standards needed for use in high pressure common rail engines. Anyone operating a modern clean diesel engine is seeing the effect, including injector replacement, DPF regeneration, and a host of other fuel quality related maintenance concerns we never saw twenty years ago. On top of all of that, today’s refined diesel fuels are less storage stable than ever before. What is on the bottom of your bulk tank can also complicate matters further. When diesel is bought wholesale, it typically meets and exceeds ASTM required industry standards, but almost always requires additional filtration to avoid excessive engine wear and premature part failures.

Having clean diesel requires an additional amount of care. Namely, you need to make sure that the fuel is aggressively filtered at 4 microns to catch the microscopic particles that are big enough to damage your modern diesel engine’s high pressure fuel rail system. Furthermore, clean diesel is fuel that is free of water and stabilized with Premium Diesel to guarantee no bacteria, yeast and other creatures can grow and further contaminate the saddle tanks on your trucks.

For more on clean diesel, see Donaldson’s description of “The New Clean” for an in-depth explanation of what ISO cleanliness and filtration mean for your diesel fleet.

Making Diesel Cleaner!

Knowing the quality of your fuel is the first step. This is done by taking samples off of the bottom of your bulk storage, as well as a representative sample from your fuel dispenser. Lab tests of those samples will tell you if you have water, biological growth, or dirt issues with your storage. The contaminants in the tank being sampled are almost always visible, which is to say that they look horribly ugly. If your fuel quality assurance has been on autopilot, do not be surprised if you find this. After gathering knowledge about your fuel, the next step is to get your fuel quality clean.

Filtration and tank bottom sampling is the start. Beyond that, the only way to improve your fuel quality performance is to filter your fuel, ensure water is not getting into the tank through condensation, and additize it with a Premium Diesel additive to upgrade the performance of the fuel. Many fleets today are seeing injector wear and continual problems with particulate trap maintenance. This is a combination of water in fuel and microscopic particles not captured by a 10 or 30 micron filter used at most diesel dispensers. You have to filter more aggressively than this.

Clean, Dry, and Premium Diese

Where To Start?

The first step is sampling your bulk diesel tank. We check your bulk tank for water and dirt to make sure and meet the specifications your engine is built for. Star Oilco can help by providing a complementary diesel test for those fleets interested in taking control of their fuel quality assurance. Usually when testing fuel, we take a sample off of the tank bottom as well as a representative sample out of the fuel dispensing nozzle.

What we usually find is ASTM specification diesel fuel (it meets ASTM spec) that is higher than you’d want (still in spec) for water with far more dirt than the OEM’s would want to see in your engine. This dirt fails to be within the “ISO Cleanliness” specifications recommended by engine manufacturers. Usually, we also see water on the bottom of the fuel tank, which is a likely source for future or current biological growth in your fuel tank.

Star Oilco can help you fix this! The first step is to sample your fuel tank.

NOTE: If you have a current biological growth problem in your bulk fuel tank or fleet, your first step is to treat that effected fuel with a diesel microbiocide to kill the bugs growing in your tank. For more on this, see our Valvtect Plus 6 Diesel Microbiocide page.

Diesel Fuel Tank Cleaner

 

  • Diesel Fuel Is Often A Company’s Largest Expense. Unfortunately, there is very little control over its quality.
  • Fuel Quality Has Declined over the last 25 years…
  • Engine manufacturers have tightened the tolerances for fuel
  • Newer tier 4 engines starting from 2008 need cleaner fuel

 

“Over the last two decades, the cetane number and the API gravity, the basic measures of crude oil quality have declined.”

—Society of Automotive Engineers, (SAE) Bulletin 872243

 

Cetane number is actually a measure of a fuel’s ignition delay. This is the time period between the start of injection and start of combustion (ignition) of the fuel. In a particular diesel engine, higher cetane fuels will have shorter ignition delay periods than lower cetane fuels.

What is a typical API gravity for diesel fuel? The classic book “Petroleum Refinery Engineering” by W.L. Nelson (4th ed., McGraw-Hill, 1958) gives numbers ranging from about 25 to 40 (with “Grade 1-D” around 40 and “Grade 2-D” around 35). In a Web search using the keywords “diesel” and “API gravity” I found a couple of sites with specs for #2 diesel fuel; these had minimum values of 26 and 30 API gravity. So a reasonable guess would be that typical #2 diesel fuel would have an API gravity of about 35; I’ll let you plug that into the above formula to get the specific gravity.

The densities of petroleum products are traditionally (especially in the U.S.) expressed as “API Gravity” The API Gravity is related to the specific gravity by the equation: API = (141.5/SPGR) – 131.5, where the specific gravity is the density relative to that of water and everything is measured at a temperature of 60 degrees F.

This winter, Star Oilco is offering complementary diesel fuel testing for any fleet operating in our service area. We are providing fuel quality testing in partnership with Hydrotex to assist fleets in our area struggling with containing the cost of fuel related maintenance.  Typically a diesel lab test costs over $200 depending on the lab.  Don’t let the hurdle of a scientific analysis stand between you and full knowledge of what is effecting your fleet.

Since the move to Ultra Low Sulfur Diesel in 2007 along with moving changes in diesel refining and biodiesel mandates fuel quality has been a moving target.  More importantly petroleum refiners and distributors follow an ASTM specification for diesel which is not as stringent as the ISO standards demanded by OEMs making the trucks on the road today.  Water and dirt in fuel are robbing your fleet of money.  Get a handle on it and move forward armed with that knowledge.

Star Oilco and Hydrotex can help you understand what is going on, what the quality of your tank bottom is, and what you need to do to reduce the cost of operating your fleet as it relates to diesel fuel.

Call Star Oilco and state you want to get your fuel tested for both ASTM and ISO specification. A member of our team will help you take the sample off of the bottom of your tank as well as from your dispensing nozzle.

Call Star Oilco today for have a sample taken and tested.

What Types of Feedstock Can Be Used To Make Biodiesel?

               What Types Of Feedstock Can Be Used To Make Biodiesel?

        To answer what feedstocks can be used to make biodiesel we need to first answer:  What is Biodiesel?

Biodiesel is created through a process called transesterification.  Transecterification is when an alcohol such as methanol or ethanol is added to an oil or fat.  This creates methyl esters and glycerin.  Methyl esters is the scientific name of Biodiesel.  Because biodiesel needs a fat or an oil to start with, this fuel can can be created with any number of feedstocks.  If you would like to learn more about Biodiesel check out this for more questions about biodiesel.

According to the U.S. Office of Energy Efficiency & Renewable Energy:

“A feedstock is defined as any renewable, biological material that can be used directly as a fuel, or converted to another form of fuel or energy product. Biomass feedstocks are the plant and algal materials used to derive fuels like ethanol, butanol, biodiesel, and other hydrocarbon fuels. Examples of biomass feedstocks include corn starch, sugarcane juice, crop residues  such as corn stover and sugarcane bagasse, purpose-grown grass crops, and woody plants. “

Renewable Energy Group (REG) performed a study in 2009 with the support of the Iowa Power Fund Board and the Iowa Office of Energy Independence that tested 36 individual feed-stocks.  Star Oilco will be spotlighting these feedstocks through our blog and our social media. The full report can be found on their site if you would like to read ahead or explore the results in more depth. We hope you find these as interesting as we did!

                                                            Babussa Oil & Beef Tallow

Babassu Oil

Attalea speciosa

Babassu oil is extracted from the seeds of the babassu palm tree, Attalea speciosa, an evergreen tree growing to 30 m (98ft) by 20 m (65ft) at a slow rate. It is hardy to zone (UK) 10 and is not frost tender. The flowers are pollinated by bees and other insects. The tree is common in Brazil, Mexico, and Honduras; it grows well in areas typically cultivated for coconut or palm. The kernels contain 60-70% oil, appear transparent, and smell like walnuts. In its natural form the oil is liquid at 20-30°C (68 – 86°F). The seeds are edible and the oil is used in margarine, soaps, detergents, lamp oil and skin products. Oil extraction results in a cake containing 15-25% protein (depending on the shell content), which is a valuable feedstuff.

In February 2008, Babassu palm oil and coconut oil were blended with jet fuel to power a Virgin Atlantic Boeing 747 during a test flight from London’s Heathrow to Amsterdam.

Beef Tallow

Tallow is a rendered form of the waste fats and greases from processing beef. Rendering is a process by which lipid material is separated from meat tissue and water under heat and pressure. Beef tallow is primarily made up of triglycerides and it is solid at room temperature. The B100 that is created from this source has a very high cloud point. “Cloud point is the temperature at which wax (paraffin) begins to separate when oil chilled to a low temperature, and it serves as an important indicator of practical performance in automotive applications in low temperatures.”  (Source)  The other uses for tallow include animal feed, soap, cooking and in the past, candles.
