Went into a pub yesterday, a friend said to landlord, what do you do with oil, "A lad used to collect it, but hasnt been for a while, there 4 cans (nearly 80L) outside, would you like to take it? I used to put it in centre of bin and pile rubbish all the way round it..........."
I explained how bad it was for the environment when it decomposes anaerobically.
10p Litre is a fair price for buyer and seller, imv. As I wrote earlier links on
http://www.vegetableoildiesel.co.uk/forum/viewthread.php?tid=8253 cover collection and WTNs etc etc.
