Biodiesel Feedstocks – Palm Oil & Perilla Seed Oil

This deeper look into biodiesel feedstock includes one that is very controversial – palm oil. We will also be covering perilla seed oil as we continue our look into different types of feedstock that Renewable Energy Group (REG) studied in 2009 in the Feedstock and Biodiesel Characteristics Report. Read more about the feedstocks we have examined in the past.

Palm Oil

Palm oil is produced from the fruit of oil palms such as the American oil palm Elaeis oleifera, the maripa palm Attalea maripa, and most commonly the African oil palm Elaeis guineensis which is originally native to the area between Angola and the Gambia. This plant is different than the coconut oil that that comes from Cocos nucifera. (Read here for more information about coconut oil as a feedstock.) The E. guineensis can grow between 60 – 90 feet high with a single stemmed palm tree. Fruits are ovoid-oblong drupes, ¾ inch –2 inches long, tightly packed in large bunches with 1000–3000 fruits (Source).Oil palm plantation on the slopes of Mt. Cameroon

The natural state of palm oil as a saturated fat, is slightly reddish and semisolid at room temperature. For every 225 lbs. of fruit bunches, typically 50 lbs. of palm oil and 3.5 lbs. of palm kernel oil can be extracted. Based on the picture of the sample, we can assume that this source has been refined, bleached and deodorized to remove the beta-carotene that gives it the reddish color the natural state of palm oil.

Palm oil is edible and is used as a cheap substitute for butter and other vegetable oils. In fact, palm oil is in about half of all packaged products that are sold in supermarket, and not just in the food, but in things like soaps, cosmetics, and detergents. The controversy over palm oil is where it is grown and how the farmland is acquired. The main culprit is the African palm oil tree. It has been introduced and grown in Madagascar, Sri Lanka, Malaysia, Indonesia, Central America, the West Indies and several islands in the Indian and Pacific Oceans.

The problem that arises is rainforests are being cut down and replaced with this profitable crop. The incredible diversity of the rainforest is replace with a single species, and this has led to reductions in animal habitats such as orangutans, elephants, rhinos, and tigers (Source). If you would like to know more follow some of the links that were supplied as sources.  As far as green house gases and the reduction of them a recent study by the University of Göttingen investigated the whole life cycle of the greenhouse gases and here are the results (Source):

“The researchers found that using palm oil from first rotation plantations where forests had been cleared to make way for palms actually leads to an increase in greenhouse gas emissions compared to using fossil fuels. However, there is potential for carbon savings in plantations established on degraded land. In addition, emissions could be reduced by introducing longer rotation cycles or new oil palm varieties with a higher yield. “

The other side of this argument is that the production of this oil is a lifeline for some countries. Malaysia and Indonesia alone employ 4.5 million people directly in the industry with millions more depending on palm oil production indirectly for employment (Source). Stopping the use of palm oil would endanger many of these people.

Perilla Oil

Perilla oil comes from the plant Perilla ocymoides, a synonym for the more common name Perilla frutescens. Perilla frutescens var. japonica in Gimpo, KoreaIt is native to India and China in the mountainous regions and cultivated in China, Korea, Japan, and India. Introduced varieties of this plant are considered a weed in the United States and go by the common names Chinese basil, wild basil, perilla mint, beefsteak plant, purple perilla, wild coleus, blueweed, Joseph’s coat, and rattlesnake weed. This herb grows easily unattended, but is toxic for cattle and horses.

This annual herb is 1 ft to 6 ft tall with a square stem and green or purple minty smelling leaves. The plant takes about 4 months from germination to start flowering, and the seeds mature about 6 weeks after.

The flowers, leaves, seeds, and sprouts are all used in Japanese, Korean, and Vietnamese foods either as flavoring or a garnish. According to Pl@ant Use:

“Perilla serves as a side dish with rice and as an important ingredient in noodles, baked fish, fried foods, cakes and beverages. The leaves can be easily dried for off-season use. The purple-leaved forms, which contain large amounts of anthocyanins, are used for coloring pickled fruits and vegetables. These forms are also very decorative ornamental plants.”

While mostly used as a food, the plant is also used for an antidote for fish and crab meat allergies in Japan and has some potential as an anti-inflammatory and anti-allergic reagent.

The seeds contain 35-45 percent oil. In addition to being made into biodiesel, this oil is also used for perfumes and sweetening agents.

Diesel storage tanks UL-2085 needed for modern Fire Code

What is required to install a fuel tank in Oregon?

A Tank that meets International Fire Code is a 2 Hour Fire Guard labeled tank.

In recent years Oregon and Washington have been moving to International Fire Code as their adopted standard. Following California with this higher standard of safety as it relates to liquid fuels.  The new standards are far more involved in their construction and therefore their installation as well. Heavy and far more expensive is the most notable standard of a modern Fire Marshall approved tank.

UL 142 – Double Wall Tanks

The old standard for diesel storage was UL-142 (commonly referred to as double wall or “diked tanks” by fleet managers).  These tanks are still made and extremely common throughout the US. If you see one of these tanks for sale and it looks like a great deal it’s probably because of an upgrade requirement causing them to sell it.  Be aware to check code in your local jurisdiction. These tanks still have a wide market for use especially for agricultural zones as well as temporary use with construction sites.

UL 2085 – 2 Hour Fire Guard and Double Wall Tanks

The new standard for storing diesel for refueling vehicles is the UL-2085. This code has been around for gasoline, it is only new in the way that Fire Marshall’s and local municipalities will require it for diesel fuels.

This standard has been around for a long time but typically was used when storing gasoline or more flammable liquids. That standard now applies to diesel fuels as well if they are being installed to refuel equipment, trucks or any other service.  Its worth noting that boilers, HVAC oil furnaces, and other plumbed stationary applications can still use the UL-142 code. Similarly agricultural use in Oregon is allowed a UL-142 use in most applications.  But for fleet fueling even if only a 100 gallon tank the Fire Marshall’s new standard is the UL-2085 concrete lined fire guard tank. It is also worth noting that if you have an installed UL-142 tank in a commercial or industrial zoned property you probably are okay with grandfathered use. But if you want to change anything the Fire Marshall and local Code Enforcement are going to be looking at the newer and safer standard.

Ask your local Fire Marshall to be sure of what the requirements are.

When discussing diesel storage tank options with your local Fire Marshall it helps to see the reason they have the standards they demand. Also be aware of other requirements that local jurisdiction may have. For instance Portland, Oregon’s Bureau of Environmental Services will often demand a cover be placed over the fueling area, an engineered concrete pad beneath it, as well as a potential oil water separator.  Usually there can be an additional permit and process associated with a tank install to meet the needs of a local Fire Marshall as well.

Two hour fire guard or UL-2085 rated tanks are the new standard in Oregon as we have adopted the International Fire Code. and the picture below says a thousand words. It will protect your property from a lake of fire preventing your diesel fuel from feeding disaster.

This is a great picture of a tank being tested for a two hour fire rating by a vendor of Star Oilco’s. Its speaks to why and what is the concern of your local regulator.

Modern Weld Company is a tank manufacturer out of California that makes great tanks to order exactly perfect for your site.

As they make what you need to the specifications you need you can make the Fire Marshall, local City Code enforcement, and your CFO happy at the same time.  If you have questions about installing a bulk diesel fuel tank to either UL-142 or UL-2085 standards give Star Oilco a call. We can help you meet UL codes for diesel, gasoline, biodiesel, or other storage needs.

Biodiesel Feedstocks – Moringa Oil & Neem Oil

We’re continuing our deeper look into different types of feedstock that Renewable Energy Group (REG) studied in 2009 in the Feedstock and Biodiesel Characteristics Report. This posts two feedstocks are Moringa oleifera Oil and Neem Oil.  To see more of the feedstocks we have already covered follow this link to the main page of feedstocks we have examined so far.

Moringa oleifera Oil

Moringa oleifera is a tree with the common names moringa, drumstick tree, horseradish tree and ben oil tree.The tree and seedpods of Moringa oleifera in Dakawa, Morogoro, Tanzania. This tree ranges in height from 15 to 30 feet tall, and is native to India, Africa, Arabia, Southeast Asia, the Pacific and Caribbean islands, South America, and the Philippines. This deciduous tree is fast-growing and drought-resistant. It loves sun and heat and doesn’t tolerate freezing weather. Moringa oleifera is a slender tree with drooping branches, brittle stems and whitish-grey corky bark. It has feathery green to dark-green foliage tripinnate leaves and yellowish-white flowers. The trees usually begin producing about second year about 300 pods, but it can take a few years to get to the 1000 or more pods a good tree can yield.

There are a vast amount of uses for this tree. According to Purdue University, almost every part of the plant has value as a food. The seeds can be eaten like a peanut, the roots can be eaten and taste like horseradish, and the leaves are eaten in salads, curries and used for seasoning.

The plant has other non-food uses include Moringa seeds being pressed for oil. This oil is used in arts and lubricating small and delicate machines, and it clear, sweet and odorless it is edible and is also used in manufacturing perfumes and hair products. The wood can be used to create a blue dye and the bark is used in tanning.

The oil from the seeds contain between 33 and 41 % oil. It is also known as Ben Oil, due to its content of behenic (docosanoic) acid. This oil can be used in the production of biodiesel, (Source) and the remaining seed cake can be used as fertilizer.

Neem Oil

The Neem tree is also known as nimtree, Indian lilac, or margosa tree. ABHIJEET (photographer) (2014, September 19) Neem tree in banana farms at Chinawal, India. The scientific name is Azadirachta indica. This large evergreen tree that is usually 49 to 66 ft tall but can get as big as 130 ft tall. This fast growing  tree is found in India, Pakistan, Sri Lanka, Burma, Malaya, Indonesia, Japan, and the tropical regions of Australia. It has long skinny leaves that are dark green in color and produces white fragrant flowers. The flowers produce a smooth olive like fruit. The seed in the center is called the kernel which contain 40-50% of an acrid green to brown colored oil.  The oil in the REG study was pure, cold pressed neem oil that was purchased from The Ahimsa Alternative, Inc.

This tree can tolerate high to very high temperatures but does poorly in temperatures below 40o F.   It grows best in dry, sandy well-draining soil. (Source)  Neem trees are drought resistant, but begin to lose leaves in prolonged droughts. The tree propagates itself by seeding and in some non-native environments the plant has been classified as a weed.

There are many uses of the Neem tree. The wood is strong and durable, the tree is related to the mahagony family, so furniture and other durable good can be made from the wood.  The leaves are dried and used in cupboards as an insect deterrent to prevent insects from eating clothes and rice. The trees oil and products can be found in shampoos, soaps creams, toothpastes and mouthwashes. The young twigs are even used as toothbrushes in rural areas. (Source)   The oil extracted from the seeds are used as a natural insecticide, repellent and fungicide. The oil is also used as a lubricant, lamp fuel and can be turned into biodiesel.

Biodiesel Feedstocks – Lesquerella Oil & Linseed Oil

We’re continuing our deeper look into different types of feedstock that Renewable Energy Group (REG) studied in 2009 in the Feedstock and Biodiesel Characteristics Report. This posts two feedstocks are Lesquerella Oil & Linseed Oil.  Here is a link to the main page of feedstocks we have examined so far.

Lesquerella fendleri Oil

Lesquerella fendleri, also known as Physaria fendleri, is part of the mustard family. (Lesquerella) Physaria Fendleri part of the mustard familyThe common names of this plant are popweed and Fendler’s bladderpod. This silvery-gray perennial has four-petaled yellow flowers that grow on a plant that is about 1 to 16 inches tall. Found in plains and mesas in the southwestern United States, it requires low water usage and is one of the first of the flowering wildflowers in the spring (Source).

Lesquerella produces hairless capsules called siliques which contain 6 to 25 seeds. These seeds contain 20-28% oil with around 62% lesquerolic acid. Lesquerella oil is a source of hydroxyl unsaturated fatty acids, and is useful as a replacement for castor oil in some applications.

While there are benefits from using this seed oil, the dark reddish-brown color of the oil is a potential limiting factor. Potential selective breeding and domestication of the plant may solve this issue, but there haven’t been much momentum at this time. That being said, there have been some studies about growing this plant for its oil and the natural gum in its seed coat for commercial use.

Linseed Oil

Linseed (Linum usitatissimum) is also known as flax in North America. The plant is an annual and can grow in large range of climates. Linseed Oil and SeedsFor example, it grows in Argentina, India, and Canada. Linseed oil has been traditionally used as a drying oil. According to REG report, these seeds contains 37-42% oil. The crude oil contains 0.25% phosphatides, a small amount of crystalline wax, and a water-soluble resinous matter with antioxidant properties.

As one the earliest cultivated field crops in the US, it has found many uses for its oils. Linseed oil can be used as a varnish, pigment binder or to manufacture linoleum. These applications have seen reductions in use due to synthetic options that resist yellowing. Other uses for this plant are as nutritional supplements and foods, although raw linseed oil can become rancid unless refrigerated.  After the oil has been pressed out of the seeds, the leftover residue makes great animal food.

As some of the traditional uses of the plant are replaced with other options, use of this crop for a feedstock in biodiesel is an option.

BioDiesel Feedstocks – Jatropha Oil, Jojoba Oil, & Karania Oil

Jatropha Oil, Jojoba Oil, & Karania Oil

We are continuing our deeper look into different types of feedstock that Renewable Energy Group (REG) studied in 2009 in the Feedstock and Biodiesel Characteristics Report. If you would like to see what feedstocks we have talked about, this is the main page and it links to the ones we have examined.

As a reminder, B20 biodiesel (B20 stands for 20% biodiesel and 80% petroleum diesel) is the drop-in solution for reduced emissions in today’s modern diesel engines. To understand some of the alternate feedstocks that can be used for biodiesel, we are examining a report that Renewable Energy Group (REG) produced in 2009. All certificates of analysis and results are for B100.

This post is a bit different as we have only one successful biodiesel created and two failures. The oils are jatropha oil, jojoba oil and karanja oil.

Jatropha Oil

Jatropha oil comes from the shrub Jatropha curcas, also known as physic nut, Barbados nut, poison nut, bubble bush or purging nut. This plant is a succulent that loses its leaves during the dry season. It is best adapted for arid and semi-arid conditions. The resistance to high degrees of aridity allows it to grow in deserts. This shrub can thrive on only 10 inches of rain for a whole year. It is native to Mexico, Central America, Brazil, Bolivia, Peru, Argentina, and Paraguay. Jatropha curcas is considered a shrub or small tree and can reach a height of 20 ft. or more.Top of a Jatropha plant as part of a hedge

 “Shrubs begin to produce when only 4 – 5 months old, and reach full productivity at about 3 years Under good rainfall conditions, nursery plants bear fruit after the first rainy season, while directly seeded plants bear for the first time after the 2nd rainy season. With vegetative propagation, the first seed yield is higher. At least 2 – 3 tonnes of seeds per hectare can be achieved in semi-arid areas.” (Source)

The seeds contain 27% to 40% oil (Source) and develop in 90 days from the flower to the seed. Trees can have a productive life of 40 to 50 years without tending.

Uses of the plant include medical, edible and as a source of oil for biofuels. The young shoots and even young leaves can be cooked and eaten as a vegetable. The nuts can be eaten but they are purgative and, if eaten in large quantities, can be poisonous.

Medicinal uses include uses the juice from the bark as a treatment for malarial fevers and or using it to treat external burns, scabies and ringworm (Source).

The low maintenance and high oil content makes this plant attractive as a biofuel feedstock. In addition to its use for biodiesel, the oil has been made into jet fuels. In 2008, Air New Zealand flew a plane on 50/50 mix of jatropha oil fuel and jet A1 fuel (Source).

Currently biodiesel is being produced from this plant in the Philippines, Pakistan and Brazil.

 

Jatropha Oil and the biodiesel it produces

Jojoba Oil

Golden jojoba oil was produced from the plant called jojoba (Simmondsia chinensis), an evergreen perennial shrub grown in Arizona, Mexico, and neighboring areas. Some of the common names of this are goat nut, deer nut, pignut, wild hazel, quinine nut, coffeeberry and the gray box bush (Source). The dehulled seeds of jojoba contain 44% of liquid wax ester, which is not a triglyceride.

Seeds on a Female Jojoba BushThis shrub grows to 3 to 6 feet tall and some can get as tall as nearly 10 feet. The fruit is acorn-shaped and .4 inches to .8 inches long.  The seed is dark brown.

Uses of the plant include forage for wild animals such as deer, bighorn sheep and some livestock. In large quantities, the seed meal is toxic to many animals. The oil is different than many of the feedstocks we have discussed.

“Jojoba is unique in that the lipid content of the seeds, which is between 45 and 55 wt.%, is in the form of long-chain esters of fatty acids (FA) and alcohols (wax esters) as opposed to triacylglycerols (TAG) encountered in other vegetable oils and animal fats” (Source).

Because of this, the Jojoba oil wasn’t made into a biodiesel for this study. According to the REG Report:

“The purpose of this project was to transesterify all the feedstocks using the same procedure and if jojoba was done differently, comparisons could not be made with jojoba methyl esters. Jojoba can be transesterified and used as a fuel using a different process.”

Jojoba Oil as a biodiesel feedstock

Karanja Oil

Pure, cold pressed karanja oil was purchased from The Ahimsa Alternative, Inc.Karanja Tree source for Biodiesel Karanja (Pongamia pinnata) is a medium sized evergreen tree, and usually about 25 ft. tall but can grow as large as 80 ft tall (Source). The tree has dark green leaves and the very fragrant flowers of lavender, pink and white.  The tree grows in the humid tropic and can be found in India, China, and Japan. The seed contains 27-39% oil.

Karanja is used for oil production and has some successes in India as a feedstock. In regards to this study, they weren’t able to create a biodiesel fuel using the same procedure as the rest of the feedstocks and therefore there isn’t a sample created to test.

REG’s notes about this oil are as follows:

“Esterification was only able to reduce the FFA (Free Fatty Acid) of the oil to 0.7 wt %. Since 0.5 wt % was the maximum amount of FFA allowed in the feedstock, karanja was not made into biodiesel using the standard procedure. A small scale experiment was performed to see what would happen to the karanja when it was transesterified. A 20 gram sample of karanja oil was used, along with the standard ratios of chemicals as in the other feedstocks for the project. After the water wash step, the karanja formed an emulsion with the water and the phases would not separate. No further refining experiments were done to make karanja suitable for transesterification.”

Diesel Fuel in Portland, Oregon

What is the difference between diesel fuel in Portland, Oregon and the rest of the Pacific Northwest?

Oregon Diesel Fuel

Star Oilco delivers and sells diesel fuel in Portland, Oregon.

We are ready for your diesel needs be they off-road, on-road, biodiesel, renewable diesel, or anything else you want.

Star Oilco has simple fuel solutions to keep your business moving.

On the West Coast, expect biodiesel blends to be in all diesel fuel. B5 biodiesel being the most commonly found fuel. Be aware though, in Oregon,  B20 biodiesel (a 20% blend of biodiesel mixed with petroleum diesel) is extremely common at retail throughout the state. B5 through B20 blends of biodiesel are becoming more common as Oregon’s legal framework regulates CO2 emissions requiring diesel sellers to blend biodiesel or charge substantially more for every gallon they sell.

On top of that, Oregon has a 5% biofuel blend mandate that can include a number of fuels, most commonly biodiesel and renewable diesel. Washington state also has a mandate for 5% biodiesel though it isn’t as specific as the Oregon mandate.

That’s Oregon Diesel. What about Portland?

The city of Portland has a stand-along city fuel tax due to its policy goals (which cause it to codify rules for low CO2 fuels and the sources of diesel in particular), as well as its own budget needs.

Portland, Oregon Diesel Fuel Mandates

A little known fact is that Portland, Oregon has its own biofuels mandate and fuel tax structure on diesel. This mandate affects all diesel equipment both on and off-road use. It does not affect boilers or HVAC systems though most people selling heating oil and boiler fuel are still handling a 5% biodiesel product to ensure they don’t cross fuel in violation of the law.

Functionally, the city of Portland’s mandate and Oregon’s specific mandate do not make a huge difference. Your biggest noticeable difference is the higher price due to the diesel fuel tax, given that Portland’s biofuel mandate now overlaps with Oregon state’s fuel mandates.

For more on the actual code for biofuel mandates in Portland, see the Portland City Code.

Until 2019, Portland had a 5% biodiesel “methylester” mandate. This meant that Portland mandated that all diesel fuel sold inside the city must contain 5% of biodiesel or sellers of fuel inside city limits would face a fine. For years, Portland actually checked every seller of diesel for a 5% biodiesel blend in person annually. This mandate also included feedstocks and did not allow for palm oil sourced biodiesel, as palm oil is responsible for a large amount of deforestation in Indonesia and other places. The Portland mandate required that half of all biodiesel blended to meet the 5% mandate must be derived from canola and waste vegetable oil sources, as Oregon can produce them.

In 2019, the city of Portland suddenly lined up their mandate to match the state of Oregon’s, which allows for renewable diesel to be used as a feedstock. Anything derived from palm is still a barred feedstock for the fuel to meet Portland mandate requirements (which is distinctly different than Oregon’s biofuel mandate).

Portland, Oregon Diesel Fuel Taxes

(NOTE: Read this article by Star Oilco for more on Oregon Fuel Taxes Explained.

In 2016, the city of Portland, Oregon created its own diesel tax of $.10 a gallon. This tax is on both gasoline and diesel fuels sold at retail or commercially.  If you are operating vehicles over 26,000 GVW that are exempt from Oregon road tax, Portland also has a weight mile for those tax exempt vehicles.

If you are fueling inside the Portland city limits, that diesel tax will be charged at the pump when you fill up unless you are a P.U.C. tax exempted vehicle in Oregon.

Hemp Oil

Hemp seed oil comes from the plant Cannabis sativa and contains significant amounts of linolenic acid. The hemp oil in this study was sourced out of Canada and these seeds have an oil content of 33 percent. Cannabis sativa male picture of flowers

Based on Industrial Hemp Regulations in Canada:

“Industrial hemp includes Cannabis plants and plant parts, of any variety, that contains 0.3% tetrahydrocannabinol (THC) or less in the leaves and flowering heads.

Industrial hemp also includes the derivatives of industrial hemp plants and plant parts. These do not include the flowering parts or the leaves.

Examples of derivatives that are considered industrial hemp include: hemp seed oil (oil derived from seed or grain) and hemp flour.”

THC is the chemical that has psychoactive properties and is what makes the cannabis Marijuana vs Hemp.

This biodiesel sample was created with seed oil that contained less than .03% THC.

Cannabis sativa is an annual flowering plant that originates in Central Asia and is now spread world-wide. The uses of the plant include seed oil, food, recreation, medicine and industrial fiber. (Source)

The centuries of early human cultivation of these plants has created a large variety of strains that look, grow and act different.  Pictured is an example of what a Hemp or Marijuana plant looks like in bloom.

Biodiesel Handling and Use Guide (5th Edition 2016)

Where to start when fueling your fleet with biodiesel.

 

The U.S. Department of Energy’s Biodiesel Handling and Use Guide (Fifth Edition)

If you are a fleet seeking to reduce your CO2 footprint and biodiesel is your drop in solution, this book is your guide.  The Biodiesel Handling and Use Guide is the definitive user’s manual for fleets seeking to field biodiesel and blends as a substitute for petroleum diesel (available from the US Department of Energy’s Alternative Fuel Data Center).

Biodiesel is diesel-rated fuel manufactured from animal fats and vegetable oils by way of a chemical reaction. It is not diesel fuel but it has extremely similar properties, allowing it to be blended with petroleum diesel.

As a drop in fuel, it substantially reduces tailpipe emissions and cuts CO2 emission by more than half when used as a substitute for petroleum diesel. Many states and the federal government have financial incentives to encourage its use. Several states also have mandates for the use of biodiesel as a blend component with diesel fuel.

In the last twenty years biodiesel has come a long way and it is now a mainstream fuel around the United States. In just the last ten years, a great deal has changed with the complexity of diesel engines, the sources of crude oil refined into ultra-low sulfur on road diesel, and the complexity diesel fleets will encounter in operating day-to-day. This book is a scientific and easy-to-read manual to help you navigate success with modern diesel.

The Biodiesel Handling and Use Guide covers the technical aspects of biodiesel and how it differs from petroleum diesel. It also provides advice on higher blends and storing fuel onsite. This guide goes in-depth about equipment compatibility for your refueling infrastructure as well as maintenance concerns you want to get ahead of. There are also checklists included for fleets seeking to move from petroleum diesel to higher blends of biodiesel.

If you have questions or want help in using higher blends of biodiesel in your fleet, don’t hesitate to contact Star Oilco. Even if you are not in our service area, we will be here to help. Star Oilco has been helping fleets succeed with biodiesel blends since 2003.

Using Biodiesel in the Pacific Northwest.

(NOTE: B20 refers to 20% biodiesel blended with an 80% petroleum diesel percentage. B5 refers to 5% biodiesel blended with petroleum diesel which is the legally required blend percentage in Oregon state. For more on biodiesel basics, visit the US DOE.)

Biodiesel is the “Drop In Solution” used in the Pacific Northwest to reduce CO2 emissions in diesel equipment.

If you are looking to use Biodiesel in a fleet or a personal vehicle it is as easy as just asking for it.  In Oregon the fuel is everywhere.  From an Oregon and Washington state requirement for a minimum 5% of biodiesel blended with every gallon to large financial incentives this low carbon diesel fuel is ready for you if you want it.

It’s not just the Pacific Northwest.  For years B20 has been a defacto blend at some of the biggest names in fuel. When you pull up to the pump on the west coast you are likely getting B5 or B20 as a blend. In Oregon, B5 biodiesel is the required fuel by law. Oregon also has a B20 incentive for a waiver of state on road taxes.  Washington as well has requirements that biodiesel finds its way into retail and commercial diesel throughout the state.   Additionally, Oregon and California have “Clean Fuel Standard” programs which heavily incentivize low CO2 fuels like biodiesel.  Washington state is expected to pass their own Clean Fuel Standard as well this year.  Biodiesel has been a fact of life in fuel for over a decade in the United States and Pacific NW and it is not going away.

Due to a mix of federal and state incentives to use biodiesel, there can also be financial advantages for a fleet dedicated to making B20 biodiesel its fuel of choice. You can see evidence of this at truck stops and other retailers making B20 available in Oregon and Washington, as well as in the trucking lanes of the United States. America’s largest fleets are choosing B20 biodiesel in order to reduce their cost per mile. So can you.

In an effort to deliver the best value to truckers, many U.S. truck stops are blending biodiesel up to 20% when the market enables them to pass along a lower cost yet high quality ASTM specified diesel fuel to their customers. Most prominent is Pilot/Flying J, who lists where and when their sites are serving up B20 or lower blends. Pilot/Flying J buys biodiesel directly and blends on site in order to give their customers the best value possible. Loves Travel Centers also sell biodiesel blends around the U.S.

In Oregon, due to a diesel road tax waiver on B20 sales, gas station retailers Safeway, Leathers Fuel, Spaceage, and others are offering B20 biodiesel as their retail diesel offering. Oregon’s system requires the biodiesel be sourced from used vegetable oil refined biodiesel products. Biodiesel has been in Oregon’s fuel supply since 2006 when the city of Portland mandated B5 biodiesel blends within its city limits. The state of Oregon followed Portland with its own statewide mandate not long after.

(NOTE: If you operate a retail gas station and are curious about Oregon’s fuel tax breaks for biodiesel blends here is a more in depth article Oregon Biodiesel Tax Breaks for Retail Fuel Stations that explains these rules for retailers of fuel).

Biodiesel has been in our fuel system since 2006 and the technology that goes into making it has vastly improved. It is proven in diesel engine performance while also creating a diversified supply for energy and significantly reducing emissions from the working fleets of the world. Biodiesel substantially reduces emission coming out of your stack without a major impact on price because it helps to offset high diesel prices.

B20 Biodiesel A PROVEN FUEL

If you want to look at using B20 blends in your fleet, we are here to help. Star Oilco carries B20 blends for mobile onsite refueling every day of the week. We also have dyed/off-road/heating oil blends of B20. If you are an over the road fleet we can provide B20 at our cardlocks as well as help you procure it with a fleetcard over the road. Let us know if we can be of help.

BioDiesel Feedstocks – Evening Primrose & Fish Oil

The two feedstocks we are looking into this time are Evening-Primrose Oil and Fish Oil. Here is a link to the main page of feedstocks we have examined so far.  As we continue our deeper look into different types of feedstock that Renewable Energy Group (REG) studied in 2009 in the Feedstock and Biodiesel Characteristics Report.

Evening-Primrose Oil

The Common Evening-primrose (Oenothera biennis) is also known as evening star, sun drop, German rampion, weedy evening primrose, hog weed, King’s cure-all, or fever-plant.  This plant is native to North America and grows throughout most of the continental US and in Canada. Oenothera biennis (common evening primrose). Flowers and buds

A unique aspect of this plant is that it has a bright yellow flower blooms that is open in the evening and then is closed at noon.(source)  This plant can grow up to 6 feet tall and is a biennial, meaning it lives for 2 years flowering the second year. The plant has leafy branched stems that are ridged and usually has fine white hair.

According to Friends of the wild flower:

“The leaves are both basal and stem. Basal leaves taper to short stalks and form a rosette in the first year of growth. The stem leaves develop the second year when the flowering stem rises; they are alternate, lance-like, wavy edged, slightly toothed, slightly hairy on both surfaces, with one main central vein and fine laterals. They can be up to 8 inches long near the base and 1/4 as wide, but become considerable shorter near the top of the stem.”

A simple google search shows that this plant has medicinal uses, known by some of the indigenous tribes of North America for hundreds of years. Some of the common uses were to treat bruises with a poultice and use the leaves in a tea as a stimulant. The drug in the plant can be used as a sedative and and as an astringent. The oil the plant produces is full of fatty acids and is sold as a dietary supplement.

The roots of the plant can also be boiled and eaten if they haven’t flowered yet. The leaves of the plant can be used before flowering in salads. Even the flowers can be eaten and are said to have a sweet taste.

The ability of the plant to grow in arid conditions and not need a lot of water adds potential of this plant to provide nutrients, oil and medicinal material for drier locations.

Fish Oil

The Fish Oil that REG used simply says “Fish oil was obtained from a commercially available source in Peru.”  The types of fish that are used to make fish oil in Peru are anchovy, herring, menhaden or sardines.

This source was likely the same that would be purchased to produce fish oil nutritional supplements or other food products. In the production of biodiesel there is a large potential for this product. Many of the toxins and imperfections that need to come out for human consumption wouldn’t effect the creation of biodiesel.  Fish oil that is produced in the process of fish processing has potential of removing waste from going to landfills. Several scholarly papers have been written on it.  If you would like to know a little more this article was written on the waste from salmon processing in Canada.
