Bio Tech Oils UK, which turns used cooking oil into diesel, has now been slapped with a 19,000 pounds fine after a trainee worker at the company poured four barrels of toxic glycerine down a drain.
According to The Sun, the disposal of the glycerine caused the death of hundreds of fish, frogs and birds over a three-mile stretch of a river near Tredegar, South Wales.
The award-winning firm has admitted to disposing the chemicals in such a way.
Bio Tech Oils UK supplied all the generator fuel for July's Live Earth gig at Wembley.
However, the company now faces utter ruin.
