Anyone who is in business producing, transporting or disposing of waste has to comply with the legal duty of care with respect to waste.
Under this, waste must only be given to a person authorised to take it away (a registered waste carrier), and special documents describing the waste (waste transfer notes) must be made and exchanged, and kept for at least two years.
Middlesbrough Council has the power to demand to see copies of waste transfer notes, and it's an offence to fail to produce them when asked.
Offenders may go to court and face being fined, but prosecution can be avoided by paying the fixed penalty.
