Comentário geral This dataset represents the operation of a mill with regards the processing of 1 kg of canola grain with in average 18% moisture content, by using mechanical extraction followed by the use of solvent. The product considered is canola dried meal, which can be used as animal feed. According to primary data collected at a canola processing plant, between 0.60 kg of canola meal per kg of canola grain is produced. The plant is located at the south region of Brazil, and is responsible for the processing of almost all the canola produced in the Brazil by the time of the project implementation.
A current industrial process is used to obtain canola vegetable oil, through the combination of mechanical and solvent extraction, but it should be mentioned that infrastrufture of the plant is more than 20 years old. Differentiation can occurs regarding electricity consumption and type of energy feedstock used to supply the boiler. A few exceptions are applied, where data gaps are filled with information from the existing ecoinvent dataset, mainly from brazillian dataset for soybean oil. This activity starts with the transpot of the grains from the field to the plant (in average 200 km), reception, cleaning and drying of canola grain up to 13% moisture content, followed by oil extraction, and disolventizing, drying and griding of meal,resulting in dried meal, being conidered a gate-to-gate system. An allocation approach is applied based on a massic criterion.
