Apparently a significant proportion of material put in the blue recycling bins is not clean waste. This contaminates other waste , increasing the chance that entire consignments are rejected. Since the waste recycling market is increasingly demanding, the volume of recycling reduces and so does the income from it.
We are asked to ensure that what we put in our blue bins is both clean and appropriate for recycling. This article on the Suffolk Recycling website sets out what can be recycled and includes a document you can download as a reminder.
