As the author and link mention, the key is whether this is commercially viable. It mentions that the factory
should be able to produce about 35M L of crude from about 80k tons of tires (sorry, gotta use American
spelling in my post! :) ).
According to some slipshod math of mine, 35 million liters of oil comes to about 220,458 (approximately) barrels of oil (one barrel = 42 US gallons or 158.76 liters). You can run through that much oil in less than a day, probably, but the point is that they can get oil from something that would otherwise be going to waste.
Now, what's interesting is the tires themselves. Used tires have a lot of uses, like making pavement, surfaces for playgrounds, shoe treads, and a host of other things. What I thought was funny is that around the time the Firestone tire recall broke, NPR interviewed the head of a used-tire reclaiming company (they're one of the firms that makes old tires into different things) and asked if they were pleased about those 6.5 million tires. As I recall, the president of the company kind of snorted and said that 6.5 million tires was small change compared to what they were used to dealing with.
