Economical and tribological aspects of usage of native oils obtained from waste berry seeds as alternative bases of lubricating substances

Key words:

base oils, motion resistances, wear, berry seed
extracts, extracts obtained under supercritical CO2
conditions.

Summary
The article presents the assessment of economic and tribological aspects of the use of
native oils obtained from waste seeds: blackberry, raspberry, blackcurrant and chokeberry as
ecological, alternative bases of lubricating substances. On the basis of current literature
reports, economic and environmental aspects of oil production from waste seeds of berry
plants by supercritical carbon dioxide method were presented. The influence of the type of
base oil used on resistance to motion, wear and anti-wear properties of the obtained lubricants
was also analyzed. Two types of tests: seizure tests, with linear load increment and at constant
load (T02 four-bullet-tester device) were carried out.
