Crude glycerin 60%

This Glycerin is fully vegetable and is created as a by-product in the production of biodiesel. Biodiesel is usually produced from rapeseed oil, but this can also be sunflower or soybean oil. The process consists of pressing the oil seed, after which the crude oil is refined. Then it is processed by means of esterification converted into biodiesel and glycerin. The latter covers approximately 10% and finds its way towards the production of biogas.
