Barcelona Uses Underground System to Handle Its Trash

 While you may not speak Spanish, watch the video anyway and get the idea of what Barcelona, Spain is doing to handle its trash. Bins are placed in every neighborhood and the trash is separated by type, etc., compressed and sent underground for processing into energy. No trash trucks -- just clean streets.

I will look into to see how much it cost to build and operate.

PS Thanks to Regina Walter, owner of Grounds, for sending me the video.
