The Biotech D product is a liquid biomass with the same combustion characteristics as heavy fuel. It is a mixture of products from the distillation of Crude Tall Oil (CTO). CTO is a residue of the Kraft process that converts resins into pulp. The Tall Oil is one of the sustainable products recognized by the European Directive (RED - Renewable Energy Directive).
Fioul Industries obtained ISCC-EU certification in July 2017 for Biotech D. ISCC-EU is a private standard that transposes RED requirements on renewable energy, that defines a list of eligible products, the traceability of products when purchased and sold, and the calculation of GHG emissions.
