As the biodiesel industry convenes for a national conference in San Diego today, one of the topics of discussions will be the loosening of the renewable fuel standard.

Among the participants will be Seattle-based General Biodiesel, a company that turns used cooking oil into vehicle-grade fuel. The company ‘s CEO is upset over backpedaling by the federal government on incentives for more use of alternatives.

KING5 Interview with Jeff Haas

Washington state has been a leader in the biofuel industry, producing millions of gallons of biodiesel and supporting hundreds of family wage jobs. Now, though, the EPA is considering reducing the mandatory mixture of ethanol and biodiesel in our gas pumps by hundreds of millions of gallons. It’s a move Freeman thinks could kill an important economic engine for Washington.

We’re calling on all biodiesel supporters to make your voice heard by writing a letter asking the Administration to approve a reasonable volume increase for biodiesel under the Renewable Fuel Standard next year.

The letter is posted at the right of this page. Simply fill in your name and contact information, and the letter will be sent via email to the appropriate federal officials. Biodiesel is the first and only EPA-designated Advanced Biofuel to reach 1 billion gallons of annual production, with commercial-scale production across the country. The industry has exceeded RFS volume requirements each year and is on pace to do so again this year, with projected production of at least 1.7 billion gallons. This is an incredible renewable fuels success story.

However, the Administration has proposed a 2014 RFS volume of 1.28 billion gallons, a sharp reduction from this year’s projected production and a potentially devastating proposal for the future of our industry. It is critical that we make our voice heard as the Administration proposes and finalizes this rule.

• How to send the letter:

Simply enter your information into the boxes provided including; your first and last name, address, and e-mail. Click the SEND button and your information will be automatically inserted into the template letter and sent to administrators at the Environmental Protection Agency, Office of Management and Budget, The White House Office of Energy and Climate Policy, and the U.S. Department of Agriculture.

• What’s the purpose of the letter?

The EPA’s draft 2014 volume proposal is moving through the regulatory process. Our industry has proven it has the capacity to continue its successful growth well beyond the proposed level of 1.28 billion gallons, and it is imperative that the biodiesel industry make its voice heard to show the real benefits of increasing biodiesel production.

King County Residents to “Get Out the Grease” on November 17th

KIRKLAND,WA - The city of Kirkland is always looking for ways to do right by its residents and the environment we all share. On November 17th from 11am-1pm, it is partnering with General Biodiesel to host the first “Get out the Grease” recycling initiative for Kirkland residents.  Rather than dumping old cooking oil down the kitchen sink, which can lead to costly visits by the plumber, residents now have a new, free recycling resource at their fingertips – a public cooking oil drop off depot where every gallon collected will be transformed into low carbon biodiesel.

The “Get out the Grease” event and new oil collection depot will be located at the North Kirkland Community Center at 12421 103rd Ave NE, Kirkland, WA 98034.  All residents of Kirkland and the surrounding areas are encouraged to attend on Saturday, November 17th from 11am-1pm to recycle their used cooking oil, learn about other recycling opportunities offered by the city of Kirkland, and meet and greet representatives from the city of Kirkland and General Biodiesel. Additionally, General Biodiesel will be hosting a raffle for everyone who attends the event, with prizes including a personal deep fryer!

The new oil-recycling depot is a permanent fixture, open and available to the public 24/7. As everyone gears up for a holiday season full of cooking and fried foods, remember to dispose of the left over oil responsibly at a collection depot.

General Biodiesel Honored for Third Consecutive Year at Green Washington Awards
News photo

In Washington State, many will agree that the word “sustainability” has become synonymous with “responsibility.”

People and businesses alike are constantly looking for new ways to incorporate environmentally responsible practices into day-to-day efforts, and they are succeeding.  Seattle Business magazine annually recognizes these efforts at the Green Washington Awards, with this year’s event occurring this past week on November 1st. The Green Washington Awards acknowledged the 50 greenest companies and institutions in Washington that demonstrate pronounced leadership in the areas of sustainability, green practices, and commitment to our environment and the future of our natural resources. General Biodiesel is proud to announce it was named to the “2012 Washington Green 50” list, making this the third consecutive year the company has been honored at the event.

General Biodiesel’s business model utilizes the power of partnerships and commerce as a means of caring for the environment and supporting the local economy. Its GreenPartner™ cooking oil recycling program has grown to include thousands of businesses since its inception. General Biodiesel collects these businesses’ used cooking oil and transforms it into biodiesel, which is a low-carbon and sustainable substitute for petroleum diesel fuel. “We are very proud of our ties to the local community and environment,” said Zach Shelton, Vice President of Recycling Operations at General. “Community scale energy production that uses local renewable resources as the input for the manufacturing process is the cornerstone of our brand. Our recycling partners make a conscientious decision to keep their waste streams local where the benefit to their customers, families, and employees is greatest. This network is very important to local sustainability.” The environmental benefits of the GreenPartner™ program are stunning – to date, millions of gallons of used cooking oil have been recycled into biodiesel. In terms of carbon footprint alone, General Biodiesel is on track to reduce the equivalent of nearly 20 million pounds of carbon dioxide from entering our atmosphere by the end of 2012.

General Biodiesel is it is the only company of its kind incorporated in Washington State whose mission is to improve the entire Pacific Northwest community. All other companies providing used cooking oil recycling services to Washington State businesses export the waste, along with the value add process as well as the potential associated jobs and environmental benefits, out of the state. General Biodiesel keeps these benefits in state and provides a cost-effective, local, and environmentally friendly cooking oil disposal alternative to the GreenPartner™ businesses that believe in a strong local economy.

General Biodiesel Achieves National “BQ 9000” Fuel Quality Certification
News photo

On July 2, 2012, following a multi-month prerequisite review period and a comprehensive two-day on site audit, the National Biodiesel Accreditation Commission (NBAC) approved General Biodiesel as a fully accredited BQ 9000 biodiesel producer.

BQ 9000 is a nationally recognized fuel quality control program run by the NBAC and the National Biodiesel Board ( Elements of the program include extensive laboratory testing in order to demonstrate fuel quality exceeds the minimum American Society for Testing and Materials (ASTM D6751) specifications, as well as compliance with storage, sampling, testing, blending, shipping, distribution, and fuel management protocols. The program is rigorous and, once obtained, provides the highest level of quality assurance to customers.

“At General Biodiesel, we earn our customer’s confidence and loyalty by providing the highest quality products and services,” said Jeff Haas, Chief Operating Officer at General Biodiesel.  “Our team proudly ensures our products meet and exceed current industry standards through a relentless focus on continuous improvement”.

General Biodiesel is Washington’s only in-state manufacturer of biodiesel produced from recycled cooking oil, a true waste-to-energy process. Biodiesel is clean burning, biodegradable, and non-toxic. It can be used in any diesel compression engine, fuel tank, or pipeline without modification. Because biodiesel fits easily into the existing liquid energy infrastructure it has become a great start to solving America’s energy independence challenges, and is considered a ‘now’ green technology.

General Biodiesel is Named a 2012 Washington Manufacturing Award Finalist
News photo

Washington State’s only waste-to-energy biodiesel manufacturing company, General Biodiesel, has been named by Seattle Business magazine as the Silver Finalist in the Emerging Manufacturer category of the 2012 Washington Manufacturing Awards.  These awards honor manufacturing companies across all disciplines based on several criteria, including employee programs, efforts made to increase productivity and quality, programs created to reduce energy consumption and waste, investments made to increase capacity, new services or products developed, and improvements to revenues and profitability. 

“Our concept is simple: we collect waste vegetable oil from businesses with kitchen fryers, recycle it into the highest quality biodiesel fuel possible, and pass the savings on to our customers,” said Yale Wong, CEO. “However, making all of this happen requires a lot of hard work.  The Emerging Manufacturer Silver Award is a very nice recognition of our success and I’d like to give all of the credit to our employees.”

This recognition marks a proud moment for General Biodiesel.  It is dedicated to growing, despite the economic downturn, and has the production numbers to prove it—in 2011, the company produced six times more fuel than it did in 2010, and has even bigger plans in store for 2012 and beyond.

2011-2012 Holiday Grease Drive Successful in Generating Positive Energy, Locally
News photo

The results are in!  For the 2011-2012 holiday season General Biodiesel and King County Wastewater Management teamed up to provide community residents with a green (and free!) solution to dispose of a common kitchen waste: used cooking oil.  This year’s grease drive was a success for the community and our local environment.

In this partnership, King County Wastewater and General Biodiesel provided a free recycling solution for used cooking oil to all members of the community in King and Pierce Counties.  This solution came in the form of 12 easily accessible drop-off tanks located in key neighborhoods.  Area residents took the extra step in promoting a sustainable Pacific Northwest by participating in the grease drive and bringing their used cooking and fryer oil to one of General Biodiesel’s containers. 

The grease drive kicked off in November of 2011 and was completed in January of 2012.  Through this recycling program, all oil collected from these tanks was recycled and transformed into sustainable biodiesel fuel.  In terms of environmental benefits, the combustion of this biodiesel in area engines represents a carbon footprint reduction of over 25,000 lbs compared to petroleum-based diesel!

Due to the positive response to these community tanks, the majority will stay in place all year.  Scroll down to find the community tank nearest you.  Thank you to everyone who participated—and continues participating—in this community oil recycling program.  Every gallon General Biodiesel collects contributes to promoting a cleaner environment, creating local green jobs, and supporting local biofuel production.

Clean tech job creation is a hot topic in Washington as employers across the board look forward to a new year of growing their business, expanding their workforce, and pushing forward with sustainability initiatives.  This is especially true for the young biodiesel industry as it builds the foundations to becoming a stable, mature market in the future.  This is only possible with support at the local, state, and national policy level.

Congressman Jay Inslee, who is running to be Washington’s next governor, visited General Biodiesel, the state’s only waste-to-energy refinery using regionally generated cooking oils to create low-carbon biodiesel, on Monday in support of the biodiesel industry’s promise as a growing employer of clean economy jobs.  “These are the kinds of innovations that will make Washington a global leader in fueling our planet cleanly and sustainably,” said Inslee at General Biodiesel’s South Seattle plant. 

According to a recent economic study by Cardno ENTRIX, an international natural resource management consulting firm, the biodiesel industry is doing its part in supporting clean tech job creation in the United States.  In 2011, domestic production soared to over 908 million gallons of biodiesel, which supported more that 31,000 jobs and generated nearly $1.7 billion in income.  Projecting forward to 2015, the same study estimates the biodiesel industry will support more that 74,000 jobs and $4 billion in income.

Autodesk Helps General Biodiesel Cost-Effectively Expand Operations

General Biodiesel, a clean tech company focused on converting used cooking oil into low-carbon biofuel, used Digital Prototyping and piping and instrumentation diagramming (P&ID) software from Autodesk, Inc. to expand and make process improvements to its main production facility. The company estimates that it saved more than $500,000 on the plant upgrade project.

As part of its plant improvements, General Biodiesel used Autodesk Inventor and AutoCAD P&ID software to design a sophisticated pre-treatment system that enables higher yields from converting used cooking oil into fuel. This pre-treatment system helps produce exceptionally clean-burning fuel and is one of the lowest carbon diesel alternatives available on the market, offering 85 percent less carbon dioxide emissions than conventional petroleum diesel.

For this year’s 2010 Green Washington Awards, Seattle Business Magazine’s judges noted an important trend toward reuse, a form of recycling that is more environmentally responsible than simple composting, and decided to break it out as a separate category.

The winner in this category was General Biodiesel, a Seattle company founded in 2006 by Yale Wong that recycles cooking oil and animal fats to produce biofuel.  All of General Biodiesel’s biofuel is sourced, produced and sold locally, enabling the company to operate at a low cost.  According to the EPA, biodiesel based on cooking oil produces 85 percent less life-cycle carbon dioxide per gallon than petroleum diesel, making it one of the cleanest burning, and least environmentally damaging, fuels on the market.  With 28 employees, the company’s process also creates local jobs.  This year the company will recycle 600,000 gallons of used cooking oil and reduce carbon dioxide production by an estimated 10 million pounds.

The company will continue to be based in Seattle, but Williams said it made sense to sell the smaller plant since very little work had been done there since last year. “It’s great to see our site being put to continued good use as a biodiesel production facility,” John Plaza, who founded Imperium in 2004 and built the Seattle plant under the name Seattle Biodiesel. “We are happy to have General Biodiesel as the new owners of our original facility.”
