A plant that turns leftover biowaste from local bakeries into advanced bioethanol has been integrated at an oil refinery in Gothenburg, Sweden.

Delivered to North European Bio Tech Oy (NEB), the first Etanolix plant from the Finnish energy company St1 will process biowaste and residues from local bakeries and spoiled bread from shops into ethanol for transport fuel.

The Etanolix process was developed as part of an EU funded LIFE+ Project and produces ethanol from biowastes. The process starts with the collection and transport of raw materials to the refinery. The ethanol plant will then produce both 85% ethanol and a by-product called stillage, which can be used as animal feed or for the production of biogas.

The 85% ethanol is then dehydrated to approximately 100% ethanol. After a quality check, the ethanol is pumped to the refinery storage tanks and blended according to specification.
