Put it in a pile, and wait. 3 to 12 months, depending on temperature and conditions, will compost it nicely.

Suggestion by Michael S
compost it, but it requires a lot of nitrogen to decompose, don’t just apply it to plants it will starve them

Suggestion by craig
Mix in an equal amount of green material, grass clippings, vegetable scraps from the kitchen, etc. Keep it moist, not wet and turn the pile at least once a week. Should be ready for you in 8 to 10 weeks

    Spread it on the ground about 6-12 inches thick, depending on the area you have available and the amount of sawdust you have. Then spread 5 layers of black and white newspaper and then pile leaves and cutting and twigs on top and dampen with a hose about every week or so. This will decompose in about 8-12 weeks depending on your zone.
