Waste oils are stored in barrels and tanks, and are subsequently transported
by tank trucks to recycling plants. Waste oil recycling is mainly done
using the vacuum distillation technique, which is the most effective of all.
During vacuum distillation, oils are divided into separate fractions of base oils which can be used
to produce fresh motor, hydraulic and other oils,
as well as tar used in the production of asphalt, bitumen, etc.
This definitely is not the only recycling technique; however, others such as purification
and centrifugation are not as effective, and the resulting products have more specific applications.
