I try this

minecraft:coal:0:100(:1 (this is charcoal) the bracket there is to prevent smileys.

but it doesnt work also where should I put that text?
S:"Item WhitelistHERE?" <HERE?
>HERE?

Thanks if you could help me out

You are looking for this section to add things exclusively to the recycler whitelist:

# Whitelist an item to be recyclable. The entry must be in the form ::::[<nbt data (seriously don't try to make this by hand)> (optional)] The weight is as though the item was added to a bag, but the items whitelisted are not added to any loot bags.
S:"Item Whitelist" <
>

How you wrote it, the config is adding coal (metadata 0 in 1.7.10, charcoal is metadata 1) with a weight of 100 and a malformed nbt entry that if I remember my code right will just throw an info message in the log.
