With the demand for more environmental protection and the use of sustainable resources for energy generation, biogenic solid fuels are moved more and more into the public interest. Among the solid biofuels, wood is the most important energy sources.

DIN CERTCO has tested and certified fuel produced from wood, as compressed wood, since the 1990s, which makes it one of the very first certification bodies for biomass fuels. Reference is made to this certification in DIN 51731, which was valid at the time.
