Pellet Focus ized fuels. Since then, the technology to manufacture pellets, as well as the technology of pellet-burning stoves, has advanced. The new burning technology in today’s stoves and inserts re- quires a very specific quality of pellet. Because of the inconsis- tencies found in pellet production, the industry has been look- ing to develop an updated standard that will meet the needs of consumers heating with pellet stoves. The original standards defined criteria for premium and stan- dard grade pellets and were quickly adopted by industry, PFI members and non-members alike. However, recent technol- ogy has made it apparent that the original standards lacked key components. The grades were too broad, test methods were not early 20 years ago, the U.S.-based Pellet Fuels Institute (PFI, www.pelletheat.org) developed an original set of pel- letized fuel standards to help bring consistency to pellet- defined, and specified quality control or quality assurance prac- tices and means of enforcement were lacking. To address these issues, the PFI Standards Committee began a standards review process in 2005 and rewrote the standards over a period of four years. The new standards defined in PFI Standard Specifications for Residential/Commercial Densified Fuel (available at http://pelletheat.org/2/StandardSpecification WithCopyright%20.pdf) were approved by membership vote in July 2008, and implementation began in February 2009. Cri- teria for the four grades of pelletized product are defined in the document, and the standardized methodology for testing each parameter is identified. The PFI Quality Assurance/Quality Control (QA/QC) Pro- gram for Residential and Commercial Densified Fuels (http:// pelletheat.org/2/QA_QCprogramREVISED.pdf) document pro- vides an industry-wide quality management system for demon- strating compliance with the standards. The QA/QC Program includes product grading based on a year’s worth of testing data, quarterly data evaluation to verify continued compliance, a pro- ficiency testing program for third-party testing laboratories, and a registration page on the PFI website to list compliant pellet producers and test laboratories. Fuel standards awareness has been one of the most dis- cussed, anticipated, and debated topics of the PFI membership for more than four years now. With the standards approved, and following input from its members, PFI has created a label to identify the pellet grade and its practical use. The label will designate a pellet fuel as Super Premium, Premium, Standard, or Utility grade and include maintenance expectations for each fuel. So, for example, if a pellet stove is labelled to burn only Super Premium grade pellets, consumers will be able to find and read the PFI label on a bag of pellets and know that they are purchasing the pellet product that will burn best in their appliance. The PFI Standards Program is in the early stages of imple- mentation, but many pellet manufacturers are more aware of the quality and consistency of their fuel than ever before. More test- ing is being done in-house, and changes are being made to im- prove the finished product. More than 20 manufacturers have made investments in testing equipment, and many others are in the process.
