Put a gate up right on the road side, that way the council are responsible for rubbish not you. If the rubbish is on your land the police can not do a thimg about it even if you catch them, you will have to take them to court but if its on council land or roads then the police will take them to court if they have the evedience to do so. You can get motion camers to record of a company called Bushware, not sure how good, they do seem quit cheep.
