Biodiesel is widely used as a renewable and clean burning alternative to mineral diesel. Its most common use is in transport where it fuels cars, buses and tracks, delivering benefits both to the environment and to vehicle engines. It improves engine lubrication, it burns more completely thereby reducing emissions, it’s virtually sulphur free and can increase engine life and fuel economy.
So it’s no wonder that it is playing a significant role in reducing reliance on fossil fuels, in reducing carbon dioxide emissions and featuring strongly in many corporate carbon reduction strategies. Biodiesel can be produced from a wide range of oil-based materials. Our raw materials include tallow, a residue from the meat industry, and other highly degraded raw materials such as oils and fats recovered from the sewerage network as well as grease trap wastes and fatty/oil food wastes. Using feedstocks that are wastes and residues of other industries means that as well as delivering significant greenhouse gas savings over mineral diesel, our biodiesel is also highly sustainable. In fact it is the most sustainable of any of the current commercial biofuels.
Our sophisticated plant pre-treats the feedstock to ensure that moisture, contaminants and other insoluble materials are removed. Oils then move to a pre-esterification phase, then onto full transesterification. After that, our by-products of glycerine and fertiliser are drawn off. The resultant raw biodiesel is washed and then purified by distillation to ensure that the quality of the final product meets European Standards. Univice will have the only site in Poland to use continuous distillation technology.
