Since 2011, biofuel may only be described as sustainable if it meets legal criteria concerning sustainability. This means that throughout the entire production chain, from cultivation to end use, it must be possible to prove that specific criteria are fulfilled.
Among other requirements it must be possible to establish where the raw material was grown and that growing it did not spoil an area of high biological value. The environmental impact of the product must also be limited throughout the entire production cycle so that emissions of greenhouse gases are not too large.
Rapeseed is cultivated
During the cultivation of rapeseed, mineral fertilizer is used that directly or indirectly contributes to emissions of greenhouse gases which leads to emissions of nitrous oxide. Farm vehicles are often driven using fossil fuel. These two issues have a significant impact on climate. However, an increasing number of mineral fertilizer producers are treating their products for nitrous oxide and this combined with farmers using more effective methods and machinery means that emissions of nitrous oxide are being reduced continuously.
Rapeseed is crushed
Energy is needed to crush rapeseed. The process also produces rapeseed feed, a byproduct that can replace soya feed that is imported and transported across long distances. This phase therefore has a positive environmental effect.
Biodiesel is produced
Rapeseed oil, methanol and energy are used during production. A by-product from the process, glycerine, can be used as a replacement for fossil fuels, which compensates for the energy used in the process. Glycerine is also used in other products such as body lotion, soap and paint.
Biodiesel is burnt
The carbon dioxide generated when rapeseed oil is burnt corresponds to the carbon dioxide consumed by the rapeseed plants during cultivation. Natural gas-based methanol creates a small surplus of carbon dioxide, but the use of renewable methanol in this phase reduces this impact.
Market’s highest climate benefit
To meet current and future environmental goals, continuous development is carried out to offer improved climate benefit for users of fossil fuels. The EU’s target is for renewable energy to account for 10% of all fuels. Verdis Polaris™ Aura consists of a base of Scandinavian rapeseed oil and renewable methanol that has no fossil origin. Verdis Polaris™ Aura therefore enables a carbon reduction of over 60% and it currently offers the best climate benefit on the market.
