Environmental Impact

Our process provides major low carbon, environmental, health, and resource utilization benefits versus comparable products made by crude refiners and ULO re-refiners that utilize hydrogen.

Scope 1 emissions are estimated from direct energy usage, and Scope 2 emissions are generated indirectly by purchases from suppliers. Scope 3 emissions are associated with feedstock and products. Our Scope 3 emissions achieve a sizeable net carbon reduction because approximately 2/3 of every ULO gallon we process becomes base oil. Base oil is not burned and thus does not generate material emissions. However, 100% of ULO not processed becomes dirty burning fuel, creating high levels of CO2 and particulate matter (PM).

2. Emissions are measured from Group III base oil with a viscosity index equal to 125. We believe this is conservative since the viscosity index of Envidigm's base oils is expected to increase as the quality of all finished lubricants (the precursor to ULO) continues to rise.
