Environmental information RAJA cardboard boxes are 100% recyclable and corrugated cardboard has the highest recycling rates of any packaging in the UK. On average, 76% of our boxes are made from recycled fibres and the ‘recycling loop’ is so efficient that used boxes can be recycled, remade and reused in just two weeks.
