The UK also has one of the most innovative food preparation facilities in Europe, the Kanes salad factory in Evesham. It is topped with a wildflower roof featuring nearly 90 species of wildflower and natural grasses. The seed mix was prepared in consultation with leading ecologists to try to minimise the impact on the local environment. The pre-grown wildflower blanket sits on top of a standing seam roof and is combined with solar panels to create an eco-friendly finish to the entire factory. The development also won the 2013 National Federation of Roofing Contractors Sustainable Roof Award for Green Roofing.
