What is the connection between a Christmas tree, chewing gum, used fry oil and 14 flashlight batteries?

Sharply focused on recycling used oil via its self-contained, sealed-cell system, the company has completed a technology demonstrator program (not for production but it is understood the results are expected to contribute to improved molecular efficiency in production) to show what can be achieved by using some unlikely ingredients to create a lubricant from recycled resources.
