Questions about ash and bones

[Beethoven-此喵非彼喵]

I have had about 53k ash and 22k bones. Is there a way to get rid of them? these things have token too much spaces. I put them outside in the field. but it still takes about nearly 3 years to disappear.

How are you storing the ash and bones? Both decay much more quickly when sitting on bare ground without any flooring beneath them while outdoors, with no roof overhead. Are you letting your enemies rot on the stockpile? Setup a separate stockpile area for bones only. Once enemies decay they leave only a few bones behind but take up an entire stockpile space. Your haulers will consolidate all those bones into a much smaller stack in the bone stockpile. That saves a lot of room. I don't really care how long it takes for the bones to decay then since they take up so little space.

The ground type also makes a pretty big difference in the time it takes for decomposition. Dirt/grass ground is the fastest while objects on limestone ground will take longer to decompose. Weather is also a factor, so make sure that these areas have no roof above them. Rain/snow speeds up the decomposition.
