Take the year-round supply of yard clippings, tree trimmings, kitchen waste and compost them! Bigger cities even give out composting bins for citizens to use along with recycling bins. Seattle has a great program for this. The compost is then used in the city parks, and even sold to the public! This reduces what is put into the landfill (which we have to pay for), and ends up with a usable, sell-able product. The program would even employ additional city employees!

Here's an article about Seattle's program:
