Technical fat for the production of biofuel is produced from technical animal fat and / or technical vegetable oils, followed by mechanical and chemical cleaning of unwanted micro and macro elements, chemical adjustment of physico-chemical parameters and subsequent transesterification.
Depending on the quality, technical fat is produced in 1, 2, 3, 4 types
An example of a product record when ordering and (or) in other documents:
"Animal fat technical grade 1 TU 10.11.50-001-09252559-2019."
Technical fat must comply with the requirements of GOST 1045, these specifications and be manufactured according to the technological instructions in compliance with production requirements and special technological processes.
According to physico-chemical indicators, technical fat must meet the requirements given in table 1.
