Our fuel comes from a variety of regional suppliers to keep your fuel close to home. The BQ-9000 certification is a voluntary fuel accreditation program that involves ISO 9000-type inspections and periodic fuel testing. The program includes: storage, sampling, testing, blending, shipping, distribution and fuel management practices. The certification process includes an application review and on-site inspection by independent auditors. Only a very small number of biodiesel producers hold the BQ-9000 certification.
The oil used in refining our biodiesel is from used cooking oil, canola and camelina crops. Canola is grown for livestock feed, however the added value is in the waste material which is processed into biofuel. Camelina is a common crop used in field rotation. It can grow in harsh conditions without the need for fertilizers while replenishing the soil. Traditionally a wasted crop once harvested, it now serves double duty as a highly efficient fuel.
Biodiesel itself is considered to be carbon neutral. During the life-cycle of the fuel, as much carbon dioxide is absorbed as is emitted. Using biodiesel in place of gasoline or petro-diesel significantly reduces your vehicle emissions. In comparing B-100 biodiesel to petro-diesel, the following figures have been provided by the EPA*
Unburned hydrocarbons are reduced by 67%
Carbon monoxide is reduced by 48%
Particulate matter is reduced by 47%
Sulfates are reduced by 100%
Polycyclic aromatic hydrocarbons (PAH) are reduced by 80%
Nitrated PAHs are reduced by 90%
*These figures are estimates. The EPA has no comparative results for gasoline vs. biodiesel emissions.
Biodiesel is a great way to reduce our dependence on fossil fuels, but completely escaping from the petroleum economy is nearly impossible. Unfortunately, there are still some non-renewable inputs necessary to get the fuel from the fields to your car’s tank. Therefore, Dr. Dan’s and the Sustainable Fuel Coop is committed to using the best quality locally sourced supply available.
Frost on your windshield does not mean that our biodiesel will gel. Dr. Dan’s biodiesel has been winterized to withstand normal winter use in the Puget Sound region. If you drive to and from work, you are heating your fuel. Just like putting a bottle of olive oil in the refrigerator, it takes time for biodiesel’s ambient temperature to drop to the point of gelling. If you drive a truck, your fuel tank is more exposed. Your vehicle’s fuel tank will reach ambient temperature sooner than a car whose mass surrounds the fuel tank.
General rule of thumb: when the weather has been cold enough long enough to freeze the ground solid, you need to take action to prevent your biodiesel from gelling. We suggest, during these cold spells, to blend petro-diesel (20%) with our biodiesel to prevent problems. When purchasing petro-diesel, make sure to verify that it is a winter blend. A winter blend petro-diesel has a lower chill point than other diesel blends. Also, look for a fuel filter on the side of the diesel pump. Petro-diesel that has been properly filtered is less likely to leave particulates in your fuel tank.
