Before and after. The compost bins at the South London Botanical Institute had fallen into a state of disrepair. I set about giving them an upgrade by renewing the front and internal sections with new posts and slats. The contents of the three sections had morphed into one general pile.

 Now it will be possible to generate compost on a three bin cycle. Ideally a composting system has more than one bin. In this case I have consolidated the good composted compost into the bin nearest the camera. The furthest bin can now be filled up ad hoc with garden and kitchen waste, then the middle one. By the time the existing compost has been used up there will be new compost ready to use at the other end. And so it goes.
