What are supermarkets doing to fight plastic?

About 6.3bn tonnes of plastic waste had been generated globally by 2015, with almost 80% of it going to landfills or the natural environment.
And despite extending the 5p charge on single-use plastic bags, major retailers in England still sold 2.1 billion in the last financial year.
In a bid to tackle the problem, the PM has called on supermarkets to introduce “plastic-free” aisles and consider taxes and charges on single-use plastic items like food containers.
