Hi Gordon, Good to make contact with a fellow bio-er! I did see your messages on the forum mate, but to be honest, I have all the oil I can use now anyway. Suzzudis (Michael) is the bloke to see, he is just starting out and he lives near Sandgate. I reckon he would welcome a good source. I collect around 800-1000 litres per month from my supplies and that is all I can handle at once, so I will bow out if that's okay. I do appreciate the offer though mate, thank you. Where do you get your other supplies from and how much are you paying for catalyst and meth? I currently get my meth from Darra and pay about $250 a drum, caustic comes from Redcliffe and pay about $65 for a 25 kg bag.
