The permit applies to any van designed to carry cargo, pick-up trucks and cars towing a twin axle trailer. It also applies to any car, MPV or SUV or other vehicle that appears to have been adapted to operate like a van (for example by the removal of seating to increase the space inside) and appears to be a commercial-type vehicle. The use of anything towed that is not a trailer originally designed for the purpose of carrying goods is not permitted and will be refused entry to the household waste recycling centres if carrying waste for disposal. Site operatives have the right to refuse entry of such vehicles without a permit. Any vehicle (including vans) carrying trade waste are not permitted at the household waste recycling centre. The sites are for residents who wish to dispose of their household waste.
