you could use it mixed with the chips as mulch in an area that you want to kill off weeds or keep them down. Ive used it on flower gardens for years, obviously also have to provide good compost/ manure etc as well over time, but it rots down fabulously, particularly beneath shrubs. Each week I used to (when I had a smaller immaculate garden!) put the clippings in a thin layer about 4-5cm deep over the whole garden. Evenly put down it looks tidy. Placed thicker over weedy areas that you want to kill off, the mulch does the work for you as it heats up. Make sure not to put it too thick though, as you dont want a stinky mess, and be careful around surface rooting shrubs such as rhodos and camellias that it never heats up enough to damage the surface roots. A whole lot easier than composting it, and builds up the humus in your garden.
