Mr de Lange is cautiously optimistic about the future for bio-fuel. It was a very useful project. We have developed a pyrolyser which works. We have looked into using it in gas turbines, diesel engines, and also conventional boilers. It's not really commercial yet, because a number of problems remain to be solved and a number of issues have to be looked at further.
Similar projects are underway elsewhere, especially in Britain, Sweden and Finland.
In Sweden they don't have their own oil resources, but they have large forests and also stringent objectives in reducing carbon dioxide emissions. On a European level there is quite some interest in this technology.
