Recycling versus recyclability In general, paper and board are easily re-usable after their manufacture. This is daily practice in paper mills by re-using dry broke from finishing operations and off-quality paper. Exceptions are special characteristics like wet-strength paper and the like. On its further path, paper and board gets converted by applying coating colours, inks,
