Burn piles, lol.
If it is mostly shrub cuttings, leaves, and small brush that is relatively small (under 1" or so) you can do this.
Find an inconspicuous natural area of your property and get an old midsize lawn mower as your "chipper", or at least an old set of blade on a better machine, just don't start trying to cut up logs with it. Dump some debris out, run over it a few times, and repeat till done. It will compost pretty darn quickly after that. I happen to have 2 acres and woods with no neighbors on 3 sides beyond that so it feels more like 10 acres, but it could work to a degree on smaller properties. Obviously you won't be doing this in the parking lot of your local storage facility or in an office/warehouse environment. But looking out my window I cannot even tell my "pile" of cuttings was ever there, as it's level with the soil in the woods and now covered in leaves. Anything leafy absolutely disappears to dust with a good mulching setup.
Worst case, do this but rake up the now greatly diminished cuttings volume for disposal elsewhere.
If you are doing really large volumes, you really should find a proper dump place. It's just a cost of doing business on that scale. And if working out of your home, you really should aim to eventually be in an area zoned AG or something else appropriate so you're not bespoiling the residential area with your debris problems, equipment, and comings and goings of employees.
Downside to that is, I have to help the owner cut the trees down AND haul it over to the house for him but each time I do it, I take about a cord of wood with me.
