Senator BROWN(4.43 p.m.) —I have no problem with that. The problem with what the minister had to say is that he claimed it is environmentally defensible to burn waste oil. It is simply not. The second point I was making was that the government is doing almost nothing to ensure that waste oil is recycled in this country. I would like to hear from the minister what the government is actually doing to ensure that waste oil is recycled, using those processes that Senator Margetts quite correctly referred to and that I was referring to as far as Tasmanian innovation is concerned.
