<s>[INST] The next text is a question of a member of the European parliament:"Regrettably, some businesses which transport waste are trying to dump waste illegally in the new Member States in central and eastern Europe.   Would it be possible to establish a European central registration system for waste transport and to require transporters to notify the system as to what type of waste they were transporting, what vehicle they were using for the purpose, where it was being taken to and whether it had reached its destination?  Can we expect the introduction of a uniform EU system for marking HGVs, railway wagons and freighters carrying consignments of waste in such a way as to distinguish between types of waste, thus making it easier for the authorities to monitor such transport? If so, when is such a system likely to be introduced?"
