Question 1

How do synthetic PAG lubricants reduce industrial carbon emissions?

Accepted Answer

PAG lubricants reduce CO2 emissions in two main ways. Their low friction coefficient increases mechanical efficiency, reducing electricity required to run motors. Their exceptional thermal stability extends oil life, lowering the frequency of oil changes, manufacturing demand, and waste disposal emissions.

Question 2

What is the typical energy efficiency gain when switching from mineral oil to PAG?

Accepted Answer

In industrial gearboxes, particularly high-reduction worm gears, switching from mineral oil to PAG can improve mechanical efficiency by 4% to 8%. This energy savings directly reduces the factory's electricity consumption, significantly lowering Scope 2 carbon emissions.

Question 3

How does extending lubricant drain intervals lower Scope 3 carbon footprint?

Accepted Answer

Extending drain intervals reduces the total volume of lubricant required over a machine's lifetime, directly decreasing Scope 3 upstream emissions associated with oil refining, formulation, transport, packaging, and downstream waste disposal emissions.

Question 4

Is polyalkylene glycol biodegradable?

Accepted Answer

Certain PAG chemistries, specifically water-soluble and low-molecular-weight PAGs, are highly biodegradable and classified as Environmentally Acceptable Lubricants (EALs), further minimising their environmental impact compared to persistent mineral oils.
