Filter item from Inventory.Add(...) if entity.Name == blacklistedItem; in "Recycler.cs" in SimpleRecycler.Recycler || Line 120

I even wrote the code for you...

    public static void DoInventoryChanges(RecyclingAnalysisContext analysisContext, Inventory inventory, Player player)
    {
        GameObject blackItem = GameObject.Find("HookConfigsHere");

        Plugin.Log.LogDebug($"Inventory changes requested");
        foreach (var entry in analysisContext.Entries)
        {
            if (entry.Amount == 0 && entry.InitialRecipeHadZero && entry.Prefab != blackItem) continue;
            var addedItem = inventory.AddItem(
                entry.Prefab.name, entry.Amount, entry.mQuality,
                entry.mVariant, player.GetPlayerID(), player.GetPlayerName()
            );
            if (addedItem != null)
            {
                Plugin.Log.LogDebug($"Added {entry.Amount} of {entry.Prefab.name}");
                continue;
            }
            ...
        }

This would be very easy and would provide players with a way to additionally remove specific items from crafting recipes which they do not want returned at all in the recycler, such as Coins.
