Two men who made £1.2m from dumping more than 14,000 tonnes of waste, including asbestos, across London and Essex have been jailed.
James Kelleher, 39, and Patrick Anderson, 51, were sentenced to 14 and 22 months respectively for conspiracy to unlawfully deposit controlled waste.
They carried out their illegal operations by using false names, Inner London Crown Court heard.
Kelleher is from Dagenham, east London, and Anderson is from Ireland.
Both pleaded guilty to the conspiracy charge.
'Blighting our environment'
The pair dumped 750 lorry loads of waste from January 2003 to June 2004 at 15 sites on both public and privately-owned lands.

Much of the £340,000 clean-up costs were picked up by the taxpayer.
It was the first time that the Environment Agency (EA), which led the investigation, had used a European Arrest Warrant to bring back a defendant from abroad to face charges. It was used to bring Anderson back to face justice in the UK after he left for Ireland.
It said the case highlighted how organised criminals were increasingly "blighting our environment" through the profitable crime of fly-tipping industrial and construction waste.
