PELLET QUALITY AND CERTIFICATIONA certified pellet complies with parameters stipulated by a certification organization. Pellet quality and type depends on raw materials and the production process. Wood pellets with high bark content are usually dark, while pellets manufactured from wood without bark are light. As far as colour goes, the drying process plays a key role: during this process, the material can be singed, and in this case white changes to grey. But this has no effect on the capabilities of the pellets as fuel and source of heat, ash content, resistance, and abrasion.Certification regulations differ in individual countries, for example:Austria – ONORM  7135.Germany – DIN 51731 a DIN plus.Great Britain – The British BioGen Code of Practice for biofuel (pellets)United States of America – Standard Regulations & Standards for Pellets in the US: The PFI (pellet)Switzerland – SN 166000Sweden – SS 187120Currently Ukraine and Russia have no pellet quality standards. Mandatory certification requirements are also lacking for similar products at a legislative level. Manufacturers in Ukraine and Russia primarily use the German DIN plus standard. As of 1 January 2010, Europe has new quality standards for fuel pellets (EN 14961-2) that will be certified via an international EN plus certificate. ENplusThe ENplus certifications system was created in 2011 as the result of an agreement within the scope of the EPC (European Pellet Council), and thus enjoys the support of the entire European pellet manufacturing industry.The certification scheme is based on EN 14961-2, and its objective is to promote high-quality wood pellets throughout Europe as a non-industrial source of energy.A key advantage of ENplus certification is that pellet quality is monitored throughout the process that includes production, storage, and transport to the consumer.Not Just Certified PelletsENplus certification also involves supervision of the production system and adoption of specific procedures that always allow for timely delivery of high-quality pellets.Who Manages Certification?ENplus certification is directly managed by associations representing the interests of their country’s industries that are part of the EPC, which is in turn part of AEBIOM (European Biomass Association), the owner of the licence for the ENplus label.
