The Environment Agency has hosted an international summit on tackling waste exports.
Authorities from more than 30 countries were represented by a total of 100 delegates at the event in Liverpool.
EA national intelligence manager Chris Smith gave a presentation on how the watchdog tracks down international waste criminals, and how international intelligence is shared.
Smith said: “The illegal export of waste is a global problem that requires a global response. This illegal trade has a detrimental effect on communities and the environment, creates financial disadvantages to legitimate business and can create a negative image of the UK waste industry.”
Waste minister Lord Taylor said: “As regulators, one of the key ways you can achieve more without necessarily expending significant resources is to share your knowledge, experiences and expertise as regulators and learn from each other.
“Working together you can achieve much more than working alone. The illegal export of waste is a global problem and requires countries to work collaboratively to ensure the controls put in place to protect vulnerable countries are not exploited.”
