A plant that turns leftover biowaste from local bakeries into five million litres of advanced bioethanol has been integrated at an existing oil refinery in Gothenburg, Sweden.
Delivered to North European Bio Tech Oy (NEB), the first Etanolix plant from Finnish energy company St1 will process feedstocks such as biowaste and process residue from local bakeries and bread from shops that is past its sell-by date into ethanol for transport fuel.
The ethanol plant has been integrated into the St1 oil refinery in Gothenburg, with staff also operating the Etanolix plant.
The Etanolix process has been developed as part of an EU funded LIFE+ Project and produces ethanol from biowastes.
Steps to producing Bioethanol;
- Raw-material from the food industry is collected and transported to the refinery
- The ethanol plant produces both an 85% ethanol and a by-product called stillage. The stillage can be used as animal feed or the production of biogas
- The 85% ethanol is then dehydrated to approximately 100% ethanol
- After a quality check the ethanol product is pumped to the refinery storage tanks and then blended to finished product according to specification
- Delivery of the gasoline from the refinery to terminals and retail sites.
The Finnish investor of the new Gothenburg ethanol plant, NEB, is an associated company of SOK Corporation and St1.
The production capacity of the plant will be leased to North European Oil Trade Oy (NEOT), sister company to NEB.
The Gothenburg project has been selected for inclusion in the Life+ programme of the European Commission, which provides funding for projects for instance on energy, the climate, environmental management, industry and production, waste management and environmental policy.
