A businessman who illegally dumped waste across parts of north Wales profited more than £8m a judge ruled today.
William O'Grady was given a confiscation order of £213,525 which he will have to pay within six months or he will serve two years in prison.
He was found guilty of dumping construction waste at three sites in Caernarfon.
The Environment Agency for Wales said: "We want to send a clear message to criminals that we will not only prosecute them for environmental offences but also pursue them for benefits derived from their illegal activities.
"This is important not only for the sake of the environment and people’s health, but also for the wider waste industry. It’s important that businesses that work within the law are not disadvantaged by illegal operators."
