My final question is for Ms. Leung.
Your business model depends upon an adequate supply of material. I hear Mr. Hargreave saying we're at 25% diversion rate and we could be at 60%. Both of you agree that if you look at it differently it is actually a huge amount of value that we're just flushing down the toilet. So the question I have for you is this. Can you access sufficient amounts of material on a regular basis at a cost level that can keep you going 100% on a daily basis?
