One of the UK's largest waste management companies has been convicted of breaking the law on overseas exports.
The Environment Agency prosecuted Biffa Waste Services Ltd for sending waste collected from households, such as used nappies and food packaging, that the Company claimed was waste paper, to China.
The export of unsorted household recycling waste from the UK to China has been banned since 2006.
After a three-week trial, a jury at Wood Green Crown court found Biffa guilty of two breaches in May and June 2015. Paper can legally be sent to the People's Republic, but heavily contaminated other waste cannot.
The Jury did not accept Biffa's version of events, that consignments leaving its depot in Edmonton four years ago complied with the law because they comprised of waste paper.
Evidence gathered by investigators at Felixstowe port clearly identified the contents of seven 25-tonne containers bound for China as including, plastics, electrical items and metal.
In fact, when Environment Agency officers searched the cargo, they found everything from women's underwear and plastic bottles, to metal pipes and even a damaged copy of a 12-inch record (by Deee-Lite).
Instead of waste paper, investigators discovered diverse discarded debris such as shoes, plastic bags, an umbrella, socks, hand towels, unused condoms, video tapes, toiletries and electric cables. The nappies and sanitary towels gave off a pungent "vomit-like" smell when inspected by Environment Agency officers.
Biffa was also trying to export laminate flooring, coat hangers, pet food containers, toilet wipes, latex gloves to china.
Jurors heard Biffa used two companies, or brokers, to act as intermediaries to manage the deal to send the waste to two delivery sites on the South China Sea coast.
The first broker took up a request from a Chinese client in April 2015 to arrange a shipment of 5,863 tonnes of mixed waste paper by contacting Biffa. A price of around £350,000 was agreed for the export, due to take place the following month.
At the same time, Biffa agreed with a second broker to ship 4,992 tonnes of mixed paper in a contract worth almost £290,000.
The Environment Agency prevented any of the seven containers from leaving Felixstowe.
Sarah Mills, an enforcement manager from the Environment Agency said, "our officers found anything and everything in Biffa's containers at Felixstowe. They were marked as waste paper, but contained a totally unacceptable level of contamination with other waste".
"The guilty verdicts justify our decision to prosecute Biffa".
Biffa pleaded not guilty at an earlier hearing to two counts of breaching the Transfrontier Shipment of Waste Regulations SI 2007/1711. These Regulations make it an offence to breach the European Waste Shipment Regulations 1013/2006, which bans the export of waste collected from households to China.
The Judge deferred sentencing until 27 September. The Court was told the Environment Agency and Biffa had agreed a figure of £9,912 to be paid for proceeds of crime.
