Compost Kitchen Scraps

One way to keep a huge amount of material from landfills is to compost. DC Urban Gardeners has a great website about composting: Composting 101 for DC Residents. However, many in urban areas may not have the space to compost. Common Good City Farm on 3rd and V Streets NW will be collecting kitchen scraps and other compostable materials after February when they reopen the farm. Common Good City Farm is an amazing place. Since January 2007, they have provided over 400 bags of fresh produce to low-income DC families, taught over 600 DC residents in workshops, engaged over 500 DC school children, and hosted over 1000 volunteers. I'll bet that some DC residents compost, even though they don't have enough space to use their compost. Is there some place where people could donate their compost? To the DC city government? To local neighborhood associations?
