18 Mar 2022 --- New research from DS Smith exposes the “Dirty Dozen” – the top 12 items contaminating mixed or paper recycling streams due to plastic and food presence. The most commonly recycled culprits include junk mail, food trays and pulp fruit trays. The research also shows that over a third (36%) of UK consumers don’t believe their recycling impacts the environment. This “Dirty Dozen” results in an average of 391 million bin bags worth of plastic waste being collected from one paper mill alone every year.
