Solid Biofuels in Trading Form in Global Markets

The objective of this chapter is to provide unambiguous and clear classification principles for solid biofuels and to support efficient trading of biofuels and good understanding between seller and buyer. In this chapter, the traded forms of solid biofuels are presented. The classification of the solid biofuels in this chapter is based on the biofuel origin and source. The standardized properties of graded wood pellets, wood briquettes, wood chips, firewood and non-woody pellets, and briquettes are explained. This chapter also presents the ENplus certification scheme, a scheme initially designed in 2010 by Deutsches Pelletinstitut GmbH (DEPI) as a quality certification scheme for wood pellets in the heating market and which has prevailed in the field of solid biofuels standardization. A reference is also implemented for other wood pellet standards. The chapter concludes with the required fuel quality assurance and control processes.
