The other day while Googling composting and worms, I happened upon a municipal composting program that was selling bins that had been converted from large green recycling cans, the sidewalk ones with wheels. They were set up just like the 55-gal flow thru systems that show up on this forum: access door on the lower portion and grid to hold back the composting materials. I meant to share it here, but now I can't find the website. Has anyone else seen this?
