10/19/16 UPDATED....Welcome....to the New EXTREME ----this excellent SS still intact, XTRM had endured crazy accumulation in early July and coming off its 52 week lows, and first in was VFIN and then PUMA accumulated and cleared out the box in July from .0013 to 0024. I thought that was very interesting. A month later, as one may have wanted to accumulate XTRM, they walked this down on no volume to VNDM...who has been accumulating suspectingly here at .0011 and .0012. Box was tested from August 1 to Oct 15th. Retail bids moved up to .0013 to .0014 in order to accumulate anything. Even then- jumped by VNDM. Move north to be expected as this was walked down from .005 on low volume comparatively.
Nobody here is talking about XTRM quite yet as it has gained strength off the bottom and showing more accumulation then ever since early July. This fell on lack of investor confidence in the past performance of the CEO - not the fundamentals or technicals. However, There now appears two new leaders in major executive positions assisting the embattled CEO and turning the ship around here. With a brand new website, selling products and generating revenues ....welcome..to the brand NEW Extreme XTRM!!!

President Obama To Sign Farm Bill Today Legalizing Hemp Cultivation: http://www.otcmarkets.com/stock/XTRM/news
Company President Joe Spadafore stated "Today is a very exciting day for us. Extreme has many projects in the pipeline to go after the growth in the cannabis sector. On behalf of XTRM Investors we would like to congratulate President Obama on today's signing".
February 7, 2014 Corona, CA - Extreme Biodiesel, Inc. (XTRM) announced today through its wholly owned subsidiary that President Obama will sign the $956 billion farm bill on as he travels to Michigan State University to extol the benefits of a thriving agricultural sector for the nation’s overall economy.
White House officials said the president would also take the opportunity to highlight growth in the farming economy during the last five years, and to note how agriculture has contributed to the economic recovery.
The White House released a report on Friday from Mr. Obama's Council of Economic Advisers that says farm income has risen significantly since the president took office in the depths of the recession.
"The past five years represents one of the strongest periods in our nation's farm economy," the report notes. "Not only does American agriculture put food on the table of American families at affordable prices and provide raw material for a range of vital purposes, it also supports one out of every 12 jobs in the economy. The hard work done on the farm is felt throughout our economy, particularly when agriculture is thriving."
Recently Extreme Biodiesel Inc. Announced that the Company wholly owned subsidiary XTRM Cannabis Ventures has just completed assembly of its first Mobile Hemp To Biodiesel Production Unit.
A problem for the biofuel industry has always been locating cost-effective products for conversion into biodiesel. Until recently Hemp was simply too expensive to consider for biodiesel, but with the passage of the farm bill hemp costs are expected to decrease. Given that Hemp seed has a better cloud point and cetane value plus similar oil content to other seeds such as Canola, Hemp will quickly become a viable and better alternative.
Company President Joe Spadafore stated "Today is a very exciting day for us. Extreme has many projects in the pipeline to go after the growth in the cannabis sector. On behalf of XTRM Investors we would like to congratulate President Obama on today's signing".

Biodiesel > The Fuel of The Future
Welcome to Extreme Biodiesel, home of the "Extractor", our standard water-wash processor, and the "Extreme Extractors", with our exclusive 2 and 5 hour waterless filtration systems.
Our new "Extreme Mini-Refineries" produce at least 600 gallons of biodiesel per day! We can also custom-build larger processors to accommodate your biodiesel needs.
After years of research and development, Extreme Biodiesel offers the finest constructed and most user-friendly processors in the biofuel industry. We are the cutting edge leaders in new technology and will continue to achieve technological advances in biodiesel production in our on-site laboratory.
At Extreme Biodiesel, we use only the finest components in constructing biodiesel processors. By using polyethylene and polypropylene materials, all of our fittings and hoses are biodiesel compatible. Unlike many biodiesel product manufacturers, we do not use white PVC, galvanized pipe or rubber hoses/tubing in our construction as these materials will eventually degrade, swell, crack and leak. The Apollo brass valves we use are made of the finest materials: including stainless steel inserts and Teflon seals.
Our custom biodiesel tanks are made with double-thick polyethylene. These tanks allow for production of 20 to 100 gallons of biodiesel in a single batch! You cannot find these biodiesel tanks anywhere but through Extreme Biodiesel.
With our exclusive "Methoxide Mixing System" you will never come into contact with both the methanol and lye together. These two chemicals are highly toxic to breathe in and will burn upon contact. Thus, we have added a separate, totally enclosed motorized methanol pump for your safety.
Our exclusive "Extreme Extractor" is a unique waterless system that completely eliminates the time consuming steps of water-washing and drying that is found in most biodiesel processors. It can produce up to 100 gallons of biodiesel in as little as 5.5 hours! And, with the "Extreme Extractor," wastewater disposal is eliminated!
If you already own a processor and are tired of water-washing, you can also purchase the "Extreme Purification System" separately. You will find all of these waterless systems well worth the price!
Biodiesel will have your engine run cooler, quieter, and eliminate up to 90% of emissions. Biodiesel will also reduce up to 90% of exhaust smoke, and most importantly, it's friendly to our environment!
Making biodiesel is simple. All you need to make biodiesel is vegetable oil (waste or virgin), methanol and lye. The vegetable oil-to-biodiesel-ratio is approximately 1:1. On average, you can produce biodiesel for as little as $0.80/Gallon!
Considering today's outrageous diesel prices, just think of the savings you will enjoy with your own biodiesel processing system from Extreme Biodiesel!
xtreme Biodiesel's Standard Extractor
The Standard Extractor is Extreme Biodiesel's original processor. It was released after 2 years of research and development. We spared no expense in our design, safety, and functionality of our Extractor systems.
Unlike most of the other biodiesel processors on the market today, we only use high quality components in the construction of our biodiesel Extractors to include: Polypropylene, Polyethylene, and Teflon. These components are fully compatible with all of the necessary chemicals for processing biodiesel.
Our custom tanks are made specifically for processing biodiesel by using double cross-link polyethylene for added strength and durability. You cannot find these tanks anywhere but at Extreme Biodiesel. Our custom tanks exceed the standards of all those found on the Internet today!
The Standard Extractor utilizes a water-wash process to purify the biodiesel. It is as simple as connecting a garden hose to the Extractor and turning on the water. The Extractor does the rest. The water-wash process puts out about 4 gallons of water per hour in a fine mist over the top of the biodiesel. Because the water is heavier than oil, it falls through the biodiesel and captures all of the soaps, glycerins and methanol, leaving a clean washed biodiesel.
At this stage, drain the glycerin from the bottom of the tank. Glycerin can be composted or you can make soap with it. Your biodiesel is now ready to be dried.
The drying of the biodiesel is done either by Mother Nature and her sunlight, or simply by heating up the biodiesel until it is clear and dry.
Once dried, you are now ready to experience the benefits of Biodiesel!
| ||* All systems receive a complete titration kit that includes a digital scale, pH solution w/color chart, pipettes, beakers and bottles. Also included is a step by step illustrated operation manual, safety goggles, gloves and bung wrench. |
Extreme Biodiesel's Extreme Extractor
The Extreme Extractor is our exclusive waterless purification system that comes in 2-hour and 5-hour models. Our Extreme Extractor is designed after the Standard Extractor; however, one great addition has been made. We have added a dry wash, or "waterless" system that eliminates the need for water-washing. This results in a faster yield of biodiesel!
The Extreme Extractor purification system is based on a basic concept that the biodiesel industry adopted a few years ago. It works on the same principle as Ion Exchange. We at Extreme Biodiesel have taken this concept and adapted it to the small-scale process used in our systems.
The filtering agent used is our own blend of products that create this unique system. This will only add .11 cents per gallon to your total per gallon price and with the time saved, it is well worth the minimal expense.
Extreme Extractor 2-Hour Purification System
The 2-hour system can filter 100 gallons of fuel in 2 hours and be ready to burn in any diesel motor. So, that means in a total of about 5 hours, you can go from vegetable oil to clean burning Biodiesel.
Maintenance on the filter system is a breeze. It's as simple as performing a flush cycle on the first tank using Methanol every 3000 gallons. This methanol can then be reused in your beginning process.
Every 12,000 to 14,000 gallons, you change out one tank of media that you can purchase from Extreme Biodiesel. The spent media can then be composted or just thrown away. It is 100% biodegradable.
Extreme Extractor 5 Hour Purification System
The 5-hour system can filter 100 gallons of fuel in 5 hours and be ready to burn in any diesel motor. In about 8 hours you can go from vegetable oil to clean burning Biodiesel.
Maintenance on the filter system is as simple as performing a flush cycle on the first tank using Methanol every 1000 gallons. This methanol can then be reused in your beginning process.
Every 5000 to 6000 gallons you change out one tank of media that you can purchase from Extreme Biodiesel. The spent media can then be composted or thrown away. It is 100% biodegradable.
**With both of our Extreme Extractors, the dry wash purification system is the best possible way to purify your biodiesel in the quickest way known. You can feel confident that the biodiesel coming from your new Extreme Biodiesel waterless system will be a quality fuel you can count on!
Extreme Biodiesel's Extreme Mini-Refinery
The Extreme Biodiesel Mini Refinery is extremely unique in the world of Biodiesel. This waterless system is the only system on the market that can make 600 gallons per day utilizing the best technology known in the industry-and at minimal cost.
The Mini Refinery is built to be used continuously, every day, and does not require rest. We construct this refinery using only the finest materials available.
The Mini Refinery includes a heating system that is an electric pass-through heater and a 300 gallon tank and filtration system. This way you know before processing that your oil is free of large debris. You can also choose any voltage configuration.
We now offer a new optional waste oil heater that runs on vegetable oil, as well as, biodiesel. Not only will this reduce your processing cost, but it will also earn you money. You may qualify for state and federal tax credits for burning waste oil. Check with your local tax authority.
The filtration unit on the refinery will run 3000 gallons before requiring a methanol rinse, and will last 12,000 to 14,000 gallons before needing to recharge the system.
All of this is wrapped into one tidy package that only takes about 25 feet x 10 feet of space. This is truly an incredible mini refinery and at only $19,999, it is by far the most "bang for your buck!"
In today's world, one can hardly escape the subject of fuel prices and fuel supply. For a number of different reasons people have turned from standard petroleum based fuel sources and looked for a reliable alternative fuel. Biodiesel is one such fuel that experts and enthusiasts have embraced as not only their idea of a "fuel of the future", but is also their choice for a fuel for today. But, what isBiodiesel?
Biodiesel is a fuel containing some of the same traits as conventional diesel fuel.Biodiesel is made from high quality vegetable oils through a manufacturing process that can be done on a large scale - such as a refinery, or on a small scale - such as a home Biodiesel kit. The primary use forBiodiesel right now is as a substitute for petroleum based diesel fuel.
In different parts of the world, different plants are used as the source for the vegetable oil that is made into Biodiesel. Theoretically, any vegetable grown can be broken down and turned into Biodiesel, but right now most Biodiesel producers use one primary crop as their source. In America, the primary crop grown for Biodiesel production is corn. Corn, being one of the more common crops grown in American, provides a readily available supply of vegetable matter for Biodiesel manufacturers. In much of Europe, rapeseed is used in the production ofBiodiesel. And, in Southeast Asia the primary plant grown for the manufacture of Biodiesel is Soy. After going through the manufacturing process, there is little difference in the properties ofBiodiesel made from one plant over another.
The process used to manufacture Biodiesel from pure vegetable oil is called ester interchange. In the process, the vegetable oil is combined with a much smaller amount of Methanol. Methanol can be manufactured by the fermentation of starch or sugar and it can also be produced from natural gas. The vegetable oil and methanol are placed in a small quantity of an alkaline catalyst and it is in this process that the chemical makeup of the vegetable oil is altered. The result is a clean burning fuel with a viscosity (flow properties) approximating that of standard diesel fuel. During this process, approximately 90% of what is manufactured is Biodiesel fuel, while the remaining 10% is in the form of the glycerine that was broken down from the vegetable matter. This glycerine can also be used in other applications in the chemical industry, making the manufacture of Biodiesel practically waste-free.
The current uses for Biodiesel are mainly limited to that of being a cleaner burning replacement for petroleum based diesel fuel. Biodiesel can be both economically viable and highly efficient for most mobile applications. There may be some minor performance and usage differences between diesel and Biodiesel and they will vary from vehicle to vehicle. It is possible for most modern diesel engines to burn standard Biodiesel. Currently, Biodiesel is also marketed as a Biodiesel/Ethanol mix or a Biodiesel/Diesel mix.
Still a young industry by any measure, Biodiesel is on it's way to becoming one of the brightest lights in the search for a viable alternative-fuel.
Biodiesel Myths & Facts
Myth: Biodiesel is an experimental fuel and has not been thoroughly tested.
Fact: Biodiesel is one of the most thoroughly tested alternative fuels on the market. A number of independent studies have been completed with the results showing biodieselperforms similar to petroleum diesel while benefiting the environment and human health compared to diesel. That research includes studies performed by the U.S. Department of Energy, the U.S. Department of Agriculture, Stanadyne Automotive Corp. (the largest diesel fuel injection equipment manufacturer in the U.S.), Lovelace Respiratory Research Institute, and Southwest Research Institute. Biodiesel is the first and only alternative fuel to have completed the rigorous Health Effects testing requirements of the Clean Air Act. Biodieselhas been proven to perform similarly to diesel in more than 50 million successful road miles in virtually all types of diesel engines, countless off-road miles and countless marine hours. Currently more than 300 major fleets use biodiesel.
Myth: Biodiesel does not perform as well as diesel.
Fact: One of the major advantages of biodiesel is the fact that it can be used in existing engines and fuel injection equipment with little impact to operating performance. Biodiesel has a higher cetane number than U.S. diesel fuel. In more than 50 million miles of in-field demonstrations, B20 showed similar fuel consumption, horsepower, torque, and haulage rates than conventional diesel fuel. Biodiesel also has superior lubricity and it has the highest BTU content of any alternative fuel (falling in the range between #1 and #2 diesel fuel).
Myth : Biodiesel doesn't perform well in cold weather.
Fact:Biodiesel will gel in very cold temperatures, just as the common #2 diesel does. Although pure biodiesel has a higher cloud point than #2 diesel fuel, typical blends of 20% biodiesel are managed with the same fuel management techniques as #2 diesel. Blends of 5% biodiesel and less have virtually no impact on cold flow.
Myth: Biodiesel causes filters to plug.
Fact:Biodiesel can be operated in any diesel engine with little or no modification to the engine or the fuel system. Pure biodiesel (B100) has a solvent effect, which may release deposits accumulated on tank walls and pipes from previous diesel fuel use. With high blends of biodiesel, the release of deposits may clog filters initially and precautions should be taken to replace fuel filters until the petroleum build-up is eliminated. This issue is less prevalent with B20 blends, and there is no evidence that lower-blend levels such as B2 have caused filters to plug.
Myth : A low-blend of biodiesel in diesel fuel will cost too much.
Fact: Using a 2% blend of biodiesel is estimated to increase the cost of diesel by 2 or 3 cents per gallon, including the fuel, transportation, storage and blending costs. Any increase in cost will be accompanied by an increase in diesel quality since low-blend levels of biodiesel greatly enhance the lubricity of diesel fuel.
Myth: Biodiesel causes degradation of engine gaskets and seals.
Fact: The recent switch to low-sulfur diesel fuel has caused most Original Equipment Manufacturers (OEMs) to switch to components that are also suitable for use with biodiesel. In general, biodiesel used in pure form can soften and degrade certain types of elastomers and natural rubber compounds over time. Using high percent blends can impact fuel system components (primarily fuel hoses and fuel pump seals) that contain elastomer compounds incompatible with biodiesel, although the effect is lessened as the biodiesel blend level is decreased. Experience with B20 has found that no changes to gaskets or hoses are necessary.
Myth : No objective biodiesel fuel formulation standard exists.
Fact: The biodiesel industry has been active in setting standards for biodiesel since 1994 when the first biodiesel taskforce was formed within the American Society for Testing and Materials (ASTM). ASTM approved a provisional standard for biodiesel (ASTM PS 121) in July of 1999. The final specification (D-6751) was issued in December 2001. Copies of specifications are available from ASTM at astm.org.
Myth : Biodiesel does not have sufficient shelf life.
Fact: Most fuel today is used up long before six months, and many petroleum companies do not recommend storing petroleum diesel for more than six months. The current industry recommendation is that biodiesel be used within six months, or reanalyzed after six months to ensure the fuel meets ASTM specifications (D-6751). A longer shelf life is possible depending on the fuel composition and the use of storage-enhancing additives.
Myth : Engine warranty coverage would be at risk.
Fact: The use of biodiesel in existing diesel engines does not void parts and materials workmanship warranties of any major US engine manufacturer.
Myth : The U.S. lacks the infrastructure to prevent shortages of the product.
Fact: There are presently more than 14 companies that have invested millions of dollars into the development of the biodiesel manufacturing plants actively marketing biodiesel. Based on existing dedicated biodiesel processing capacity and long-term production agreements, more than 200 million gallons of biodiesel capacity currently exist. Many facilities are capable of doubling their production capacity within 18 months.
Myth : There is no government program to support development of a biodiesel industry.
Fact: The U.S. Department of Agriculture announced in January 2001 the implementation of the first program providing cost incentives for the production of 36 million gallons of biodiesel. Bills supporting the use of biodiesel and ethanol were also introduced to the U.S. Congress in 2003, including one that would set a renewable standard for fuel in the U.S. and one that would givebiodiesel a partial fuel excise tax exemption. More than a dozen states have passed favorablebiodiesel legislation.
The Benefits and Challenges of Biodiesel
One of the ways to make driving more sustainable is to reduce the world's dependence on non-renewable resources. By developing vehicles capable of running on renewable fuels, such as biodiesel, we're addressing concerns about the environmental impact of driving.
In the United States, biodiesel is primarily made from soybeans. It's typically sold in blends using 2 to 5 percent biodiesel (the remaining 98 to 95 percent is traditional petroleum-based diesel). These blends are called B2 or B5.
Most diesel vehicles can use B2 or B5. Diesel vehicles have been successfully operated on B20 and B100, but this is not recommended unless the vehicle's fuel system has been modified and the fuel quality controlled.
Biodiesel can also be made from waste cooking oils and animal fats, but the resulting fuel is problematic due to the wide variation in properties from these waste streams.
Benefits of Biodiesel
The use of biodiesel has several benefits:
· The production and consumption of biodiesel fuel reduces emissions of CO2, a contributor to global warming.
· Building a stable market for biofuels strengthens the farming economy and lessens our dependence on foreign petroleum exports.
When comparing fuel properties, biodiesel presents some significant challenges that must be overcome before it can be widely used at high concentrations:
· At high temperatures, biodiesel can oxidize if air is present, causing the formation of acids and solids, which can corrode and plug fuel system components. Additives can help prevent this deterioration.
· Much as vegetable oils become cloudy in the refrigerator, biodiesel will form wax at cold temperatures. These wax crystals plug fuel filters, so flow-improving additives are necessary in cold weather.
· Biodiesel tends to carry water into the vehicle fuel system instead of shedding it in the water separator, which leads to further fuel system corrosion. This issue can be addressed through proper fuel blend formulation and vehicle development.
· Biodiesel crops yield comparatively less energy per unit of crop area than that available for ethanol crops.
Expanding Biodiesel Use
To allow for more extensive use of biodiesel, we're working with other manufacturers and fuel providers to address concerns related to use of higher biodiesel concentrations and establish national and international specifications for biodiesel quality.
When biodiesel fuel quality can be controlled, we expect that controlled fleet operations will be able to switch to next-generation biodiesel-capable vehicles.
We're conducting research with Michigan State University to discover potential fuel-processing steps to improve the properties of biodiesel. If successful, this research will open the door to more extensive use of biodiesel.
What is Biodiesel?
Why should I use biodiesel?
Biodiesel is better for the environment because it is made fromrenewable resources and has lower emissions compared to petroleum diesel. It is less toxic than table salt and biodegrades as fast as sugar. Since it is made in the USA from renewable resources such as soybeans, its use decreases our dependence on foreign oil and contributes to our own economy.
Is Biodiesel the same thing as raw vegetable oil?
No! Biodiesel is produced from any fat or oil such as soybean oil, through a refinery process called transesterification. This process is a reaction of the oil with an alcohol to remove the glycerin, which is a by-product of biodiesel production. Fuel-grade biodiesel must be produced to strict industry specifications (ASTM D6751) in order to ensure proper performance. Biodiesel is the only alternative fuel to have fully completed the health effects testing requirements of the 1990 Clean Air Act Amendments. Biodiesel that meets ASTM D6751 and is legally registered with the Environmental Protection Agency is a legal motor fuel for sale and distribution. Raw vegetable oil cannot meet biodiesel fuel specifications, it is not registered with the EPA, and it is not a legal motor fuel.
For entities seeking to adopt a definition of biodiesel for purposes such as federal or state statute, state or national divisions of weights and measures, or for any other purpose, the official definition consistent with other federal and state laws and Original Equipment Manufacturer (OEM) guidelines is as follows:
Biodiesel is defined as mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats, which conform to ASTM 6751 specifications for use in diesel engines. Biodiesel refers to the pure fuel before blending with diesel fuel. Biodiesel blends are denoted as, "BXX" with "XX" representing the percentage of biodiesel contained in the blend (ie: B20 is 20% biodiesel, 80% petroleum diesel).
How do biodiesel emissions compare to petroleum diesel?
Biodiesel is the only alternative fuel to have fully completed the health effects testing requirements of the Clean Air Act. The use of biodiesel in a conventional diesel engine results in substantial reduction of unburned hydrocarbons, carbon monoxide, and particulate matter compared to emissions from diesel fuel. In addition, the exhaust emissions of sulfur oxides and sulfates (major components of acid rain) from biodiesel are essentially eliminated compared to diesel.
Of the major exhaust pollutants, both unburned hydrocarbons and nitrogen oxides are ozone or smog forming precursors. The use of biodiesel results in a substantial reduction of unburned hydrocarbons. Emissions of nitrogen oxides are either slightly reduced or slightly increased depending on the duty cycle of the engine and testing methods used. Based on engine testing, using the most stringent emissions testing protocols required by EPA for certification of fuels or fuel additives in the US, the overall ozone forming potential of the speciated hydrocarbon emissions from biodiesel was nearly 50 percent less than that measured for diesel fuel.
Can biodiesel help mitigate "global warming"?
A 1998 biodiesel lifecycle study, jointly sponsored by the US Department of Energy and the US Department of Agriculture, concluded biodiesel reduces net CO² emissions by 78 percent compared to petroleum diesel. This is due to biodiesel's closed carbon cycle. The CO² released into the atmosphere when biodiesel is burned is recycled by growing plants, which are later processed into fuel. Is biodiesel safer than petroleum diesel? Scientific research confirms that biodiesel exhaust has a less harmful impact on human health than petroleum diesel fuel. Biodiesel emissions have decreased levels of polycyclic aromatic hydrocarbons (PAH) and nitrited PAH compounds that have been identified as potential cancer causing compounds. Test results indicate PAH compounds were reduced by 75 to 85 percent, with the exception of benzo(a)anthracene, which was reduced by roughly 50 percent. Targeted nPAH compounds were also reduced dramatically with biodiesel fuel, with 2-nitrofluorene and 1-nitropyrene reduced by 90 percent, and the rest of the nPAH compounds reduced to only trace levels.
Can I use biodiesel in my existing diesel engine?
Biodiesel can be operated in any diesel engine with little or no modification to the engine or the fuel system. Biodiesel has a solvent effect that may release deposits accumulated on tank walls and pipes from previous diesel fuel storage. The release of deposits may clog filters initially and precautions should be taken. Ensure that only fuel meeting the biodiesel specification is used.
