There's been a lot of talk here about the scale of putting this in and what the actual life cycle is. I'd like to refer to a significant project, our largest one that we have in California right now, where we actually converted an existing and yet no longer viable petroleum refinery. We bought a 63-acre parcel just about 10 miles east of Long Beach. It was a 100-year-old asphalt refinery. It started out as a crude refinery and we're converting that. We saved the jobs. We kept every single employee who was there.
We're converting that into a 25,000 barrel per day renewable diesel and sustainable aviation refinery. We're operating right now at about 4,000 barrels a day and by 2023 it will be at 25,000 barrels a day, all using waste products, recovered vegetable oils and used cooking oils, etc.
In terms of the life-cycle analysis of these, it's been pretty clearly established right now. We want to make sure we're comparing apples to apples with the data that is now available as opposed to data that was available 15 or 20 years ago. There have been significant advances in that.
We find that the demand for the product and our primary customers are obligated party oil and gas companies. That's who we partner with. We have a joint venture with Shell, who is our neighbour in Hamilton. We've been supplying them for over 10 years.
We find that the oil and gas companies are the ones—
