CAMPAIGNERS claim animal-waste firm Omega Proteins flouted planning conditions over the bank holiday weekends.
The company is banned from shuttling material between its two sites in Swalesmoor Road, Halifax, and Thornton Road, Bradford, on public holidays.
But residents living along the route say there were dozens of lorry movements on Good Friday and the Royal Wedding day.
Graham Fawthrop, of campaign group Smelly Wagons, said: “The plant has been operating as normal. They know full well they are breaking all the conditions.”
At a planning inquiry last year, the firm admitted carrying out illegal lorry movements.
It won an appeal to double the number of vehicles in and out of its Bradford rendering plant – but admitted it had been operating above permitted levels.
A spokesman for the firm’s parent company, the Leo Group, denied any wrongdoing on the day of the Royal wedding.
He said: “The country’s meat industry, of which we play a major part, operates throughout the year to meet supermarkets’ demands. Many businesses were operating as normal on Friday April 29.”
He refused to comment on claims about the other bank holiday.
Mr Fawthrop, who says he has video evidence, has reported the alleged incidents to planning authorities.
