Yes, we can burn the piles every day but they respawn the next morning and the whole burning and hauling the ash away process starts over. Taking a playable Sim and making that Sim the designated leaf pile burner is a waste of gaming time. I have better things for my Sims to do. I have found a couple of workarounds for this problem but the repetition of the actions and the amount of time it takes away from actual gameplay is a pain in the neck. The first time I burned all the leaf piles in my worlds it took over an hour of my gaming time before they were gone. Some piles had to be burned several times, of course, but that was the first time they had been burned. Some leaf piles did not spawn during the winter but some refused to budge no matter how many times I burned them. Each day I opened the game the first thing I had to do was take a playable Sim away from whatever tasks that Sim needed to do and have him or her travel and burn the newly spawned piles. That is not a gameplay feature. It's a bug that clearly has to be fixed.
I am not thrilled about using a mod to deal with this. I have other mods I prefer to have in my game. But I am trying to cut back on how many mods I use. If I install a new mod it has to be one that enhances my game or takes care of a bug. Lately, many of my game enhancing mods are sitting in a save file and are not in my game because the devs haven't been able to fix the bugs that affect my game the most. I am not angry about it, just feeling disappointed because this latest patch broke a lot of things that had been fixed months ago. Desperate times call for desperate measures, I guess. :)
