EN14214 standard developed in 1997 for Fatty Acid Methyl Ester (FAME). Introduced in 2004 for all EU member states. Allows 5% FAME in EN 590 diesel, meeting EN14214 standard
TBHQ is a synthetic phenol derived from hydroquinone with tert-butyl group. Used as food preservative for unsaturated oils and animal fats. Extends storage life in various foods. Applied in perfumery as fixative and industrial stabilizer. Used as antioxidant in biodiesel and in varnishes
Biodiesel was first produced in 1853 by Patrick and Duffy through vegetable oil transesterification. Modern biodiesel production emerged in 1930s through transesterification of vegetable oils. Biodiesel is made from fats and contains long-chain fatty acid esters
HVO is made by hydrocracking or hydrogenation of vegetable oil. Chemical formula is CnH2n+2 with excellent low temperature properties. Can be produced from various oils including canola, algae, and palm oil. Green diesel reduces greenhouse gas emissions by 40-90% compared to fossil diesel
Acid value quantifies acidity of water-insoluble substances like oils and fats. Measured as milligrams of KOH needed to neutralize 1 gram of sample. Determined by titration with potassium hydroxide using phenolphthalein indicator
Biodiesel prices are expected to decline in coming months. European Union imposed 36.4% anti-dumping duties on Chinese imports. North American refiners are shifting away from biodiesel production
