Just to give you a perspective in terms of.... I'll focus more on the lignocellulosic biomass like forest biomass. If you look at all of Canada, we are talking about...and this is mostly the residues. About 21 million tonnes of forest residue is available per year. If you think about the production of how much, let's say, ethanol or liquid fuel you can produce, it's generally 200 litres in a tonne.
With these residues that are available today, currently most of the operations are just piled on the roadside and burned to prevent forest fires as part of forest management practices, so these are not currently used. You can look at others, for example, straw. If you look at the whole of Canada, we are looking at about 28 million to 30 million tonnes of straw. There are some other uses, but again, the majority of this is left in the field to rot and it emits CO2. You do have the potential to use these large feedstocks, which are lignocellulosic feedstocks.
Municipal solid waste is another big one where you have about 25 million to 30 million tonnes—
