New report shows Germany's biodiesel quality continues to improve

By Ron Kotrba | May 01, 2018

Germany’s biodiesel quality management association, AGQM, has released its 2017 quality report from the sampling of biodiesel producers and warehouse operators throughout the country last year in three sampling campaigns. According to the organization, 53 samples were taken and 1,060 parameters were analyzed, all of which met or exceeded the DIN EN 14214 biodiesel standard and even stricter AGQM requirements.

“Only 14 limits were violated but all violations where within the precision of the method,” AGQM stated. “This is an improvement to the previous year where three limits were violated outside of the precision of the method.”

The parameters considered to be particularly critically by the automotive industry, including alkali metals such as sodium and potassium, all measured values below 3 milligrams per kilogram (mg/kg) of fuel, with the combined maximum limit of 5 mg/kg in the specifications. Earth alkali metals such as magnesium and calcium all measured below the determination limit of 1 mg/kg. For phosphorus, all but two values were below 0.5 mg/kg.

The detailed quality report, including an information sheet with all the average values for the individual parameters, can be found on AGQM’s homepage under “quality.”
