Process Data set: soybean meal and crude oil production (en) en

Key Data Set Information
Location BR
Geographical representativeness description Data represents the operation of a general mill in any location of Brazil.
Reference year 2015
Name
soybean meal and crude oil production
Technical purpose of product or process Typical oil mill designed for soybean oil production by means of exclusively solvent extraction (includes pre-cracking of soybeans, dehulling, oil extraction and meal processing ). No previous mechanical extraction is included.
Synonyms soybean oil extraction
Classification
Class name : Hierarchy level

General comment on data set Type of process: ordinary transforming activity Parent relation Ecospold2: none Tags: Macroeconomic Scenario: Business-as-Usual This dataset represents the operation of a mill with regards the processing of 1 kg of soybeans. The products and respective uses are indicated as follows: 1) crude oil: further refined to become edible or used as it is to produce biodiesel; 2) meal and hulls that are consumed as animal feed. Lecithin that is used as an emulsifier in the food industry is also reported as a third product in one literature, but its was disregarded as its amount represents less than 1% of total outputs and no economic market value for it was found. Although no primary data was obtained from producers, secondary data used in this dataset represents the general industrial process of most Brazilian mills (oil obtained via combination of mechanical and solvent extraction). Different sources vary mainly in terms of electricity consumption and type of energy feedstock used to supply the boiler. Data used in this dataset represents the average of 3 sources (indicated in the Bibliography); the exception applies to data gaps, in which case information from the existing ecoinvent dataset were adopted.

Time representativeness
Data set valid until 2016
Time representativeness description Data is valid for the entire period. Time period for the most of the data collected for this dataset.
Technological representativeness
Technology description including background system The technology level of this process is: Current/n/n Typical oil mill designed for soybean oil production by means of exclusively solvent extraction (includes pre-cracking of soybeans, dehulling, oil extraction and meal processing ). No previous mechanical extraction is included. Included activities start: This activity starts after the receive of soybean from the field. Following operational processes go from pre-cracking of soybeans through crude oil production. Included activities end: System boundary is at the oil mill (gate-to-gate). No further treatment of crude to refined oil is included.
