Anti-aircraft shells, shotgun cartridges and bullets were discovered on the sorting line of a materials recycling facility (MRF) run by Grosvenor Waste Management in Fengate, Peterborough, yesterday. Staff were evacuated and the police called in the bomb squad from RAF Wittering to deal with the find. The MRF was shut down for two hours while X-rays were taken. Luckily they showed that the munitions no longer contained explosives. Police had also stopped lorries visiting the site until it was declared safe. Peterborough City Council spokesman Gareth Roberts said: We can assume that they had been put in a green waste bin as that is where the contents on the sorting line comes from. Bomb Squadron media communication officer Tony Walsh said: It is important that anybody who comes across ammunition must not dispose of it in a normal waste bin or metal recycling bin. The police must be informed straight away. Roberts added: Discarding live or even spent ammunition in this way is extremely irresponsible and dangerous. The protection of people working at the MRF is paramount, and items such as these clearly compromise their safety and understandably cause them a lot of distress. We need to make sure that whoever is putting these items in their bin, whether intentionally or not, realises the potential risk to staff and understands the importance of only placing certain household materials in the green bin for recycling. This is the second time ammunition has been found among recyclables at the Fengate MRF. In March shells, bullets and cartridges were mixed in with recyclable materials sorted at the facility. On that occasion the police dealt with the ammunition.
