DeKalb County is one of the few counties that collects yard waste, composts it, and returns it to citizens for their use. I recently toured the composting facility to see how it operates.
yard waste arrives in big trailers
the material is piled into long windrows while waiting to be ground up
a loader puts it into the top of a huge tub grinder
a big truck transports the ground up material to long piles
it’s stored in the piles for 6 – 8 months. The internal temperature of the pile is taken each week. When the pile cools down it is turned, to put surface material into the center causing everything to be composted.
after several months the yard waste is almost completely broken down
piles of compost are available for DeKalb citizens at three locations
