Not all achievement diary rewards are added in game, the only one I have seen that can be collected daily is Zaff's battlestaves.
Bert will automatically deliver 84 buckets of sand to your bank each day (unless you are an Ultimate Ironman).
The Flax keeper will exchange 250 noted flax daily for 250 noted bow strings.
Robin offers 39 pots of Bonemeal and 39 free buckets of slime each day in exchange for bones.
these are just a couple picked off of wiki from the elite reward section.
