There are more than 1,000 illegal waste sites in Britain, causing huge pollution and ruining people's lives. Are the authorities doing enough about the problem?
It is all, obviously, about the money: saving it, for the waste producer; making it, for the illegal operator. "Broadly speaking, it's at least 50% cheaper to get rid of stuff illegally," says Rutherford. "Here, a legitimate company will charge £180-£200 per skip. The bad boys will be asking £100-120, cash. You can see the temptation for the producer."
Meanwhile, of course, people like Tim will be "pocketing the £100; avoiding the costs of all the various permits, licences and taxes; burning the waste; pulling out any valuable scrap metal, and selling it. You rent the corner of a farmyard or a field or an industrial unit, buy a few skips, and you start dumping. It's really very easy money."
