Reduce-reuse-recycle, or the more elaborate refuse-reduce-reuse-repair-remake-recycle,
is an easy-to-remember guide for how to become more circular.
From a sustainability point of view it is very seldom true that new is better.
In essence, it points towards lower consumption, longer usage periods, reuse of materials, and thereby prevention of waste.
Evidently, reduce-reuse-recycle is predominantly directed towards the end customer, and it clashes with consumerism and the linear-economy mantra that new is better.
