Theresa May’s new environment plan sets ambitious goals for plastic waste reduction. But there’s lots of room for slippage. One goal is to eradicate all “avoidable” plastic waste, though it’s not clear how “avoidable” will be defined. A few concrete measures are now in place, such as the 5p plastic bag charge being extended to cover all businesses in England. And, in order to tackle the spread of tiny plastic particles, the government recently announced a ban on microbeads in personal care products.
