Freedom’s Sentinel, Operation Red Dragon, Liberty Shield, National Sword and Green Quest. They all sound like the names given to military interventions of recent years. And, in fact, they all are, apart from one, which is a Chinese government programme aiming to improve the quality of recycling. And, no, it’s not Green Quest (a short lived American operation investigating terrorist financing sources). Rather, the programme seeking to prevent imports of poor quality recyclates is National Sword, a surprisingly aggressive title for such an environmentally beneficial endeavour.
