Forestry ethanol also called 2nd generation etanol
For more than a century, so-called sulphite spirit has been manufactured in Sweden, which is ethanol from residual products of the pulp and paper industry. Today there is only a sulphite factory left in Sweden, Aditya Birla Domsjö in Ornskoldsvik, and it is therefore only here that this type of ethanol is produced in the country today.
This ethanol is classified as second generation ethanol, since the raw material used is a residual product from an existing production process, in this case, special cellulose for viscose. In day-to-day language, this is also called forestry ethanol. First generation ethanol is produced from agricultural products such as sugar cane, cereals or corn.
Today SEKAB uses this ethanol in order to provide a series of premium products in the areas of both chemicals and fuel. On request, we can however produce all of our products from second-generation ethanol. These products are renewable, sustainable, and they have extremely good climatic properties.
Second generation ethanol has two major advantages. Firstly, the huge climate advantages compared to fossil fuels, which are even greater than normal bioethanol. Secondly, there is no risk that it will compete with food production since it is produced from a residual product.
It is partly for these reasons that SEKAB has established a dedicated process to develop for instance ethanol from various types of biomass and wood raw materials, and this is a process that provides very broad applications. Already today, we see a great demand for and interest in second-generation ethanol, and we aim to see large-scale production as soon as possible.
