Is there anything useful I can do with charcoal ash?

Is there anything I can do with charcoal ash from grilling other than throw it in the garbage (after it's cooled)?

Would my neighbors who garden or compost have any use for it? I grill all the time, and I hate to add to the landfill but I'm not switching to gas... Does anybody have an idea of a useful or environmentally-friendly way to dispose of it?

    If you're really on the DIY tip, you have a lot of time to kill, and you're using hardwood lump/chunk charcoal you can use the ashes to make lye which you can then use to make soap, bio-diesel, and lutefisk.

    I throw it on the bindweed and horsetails to kill them.

    Charcoal ash from briquettes is nasty and shouldn't be used. Briquettes have all kinds of crap in them that aren't wood ash. If you're using chunk charcoal, the ash could theoretically be used, but it's extremely alkaline and thus a bad idea for most of your plants. The soil in WA tends to be too alkaline already; the most common pH amendment is to try to acidify the soil, not alkalize it. I wouldn't think it would have much nutritive value aside from amending the pH.

    Throw it out.

    Could you mix it with something to use as a building material?
