Spotlight Bioenergy International No 81, 5-2015 31 On the subject of ethanol, the world’s first oil refinery integrated ethanol plant was commissioned this summer in Gothenburg, Sweden. A modular proprietary technology developed by Finnish company St1 Biofuels,the 5 million litre per annum capacity plant was supplied to North European Bio Tech Oy (NEB), a company that processes biowaste feedstock into biofuels. The plant uses biowaste and process residue from local bakeries and stale bread from shops as feedstock. It uses excess heat from the refinery for its process heat, and utilises the existing internal cooling and wastewater treatment infrastructure. The ethanol is then blended directly with gasoline and stored in the existing tank farm for delivery to the client. It is the first “export” plant delivered by Stl Biofuels. In Finland, St1 Biofuels have five ethanol plants located at various food processing and beverage industries with a combined annual capacity of 11 million litres. A 10 million litre per annum cellulosic ethanol plant is currently under construction in Kajaani and projected to begin production in mid-2016. In Norway borre gaard operates one of the world’s most advanced integrated pulpmill biorefinerïes in Sarpsborg. Here it produces advanced biochemicals, biomaterials and cellulosic ethanol. Ethanol production capacity is 20 million litres per annum. Although a so-called first generation ethanol plant Sweden’s Lantmännen agroetanol 230 000 m3 per annum facility in Norrköping is perhaps one of the most energy and resource efficient ethanol plants of its kind achieving GHG savings of up to 90 percent compared to fossil gasoline or diesel. The largest ethanol producer in Sweden it recently launched its Agro Cleanpower 95 a ED95 fuel for diesel engines. The raw tall diesel (RTD) feedstock used by Preem is supplied by Sunpine, a processing company based in Piteå, Sweden, in which Preem has a stake, together with Sveaskog, Södra Skogsägarna, KIRAM and Lawter. In 2010, Sunpine opened a SEK 350 million (≈ EUR 37.2 million) facility in Piteå to convert tall oil from the pulp industries into RTD using a proprietary energy efficient fractionation process developed by KIRAM. The RTD is then shipped to Preem’s refinery in Gothenburg. Sunpine have also begun extracting rosin to supply to Lawter. Also in Piteå, renewable dimethyl ether (DME) producer LTU Green Fuels has announced that its BioDME is being tested for industrial heating usage blended with LPG (propane). In a project with FLOGAS Sweden AB a first delivery of 20 percent BioDME blend propane has been shipped to an asphalt plant where it will be tested. BioDME is produced by gasification of black liquor, a by-product of the pulp industry at a pilot plant owned and operated by LTU Green Fuels. Its BioDME is also undergoing testing by Volvo Trucks as a diesel fuel replacement. Finnish forest industry major UP M has declared its ambition to become a major player in the production of advanced biofuels. In mid-2012 it followed suite on the crude tall oil to renewable diesel track when it began construction of its EUR 175 million biorefinery at its Kaukas mill in Photo courtesy UPM/Markku Repo
